This study evaluated the reliability and failure modes of regular and horizontally mismatched implant-abutment connections by subjecting them to step-stress accelerated life testing. The reliability was found to be not significantly different between the regular and mismatched groups. A Weibull analysis showed similar modulus and characteristic strength values between groups. The chief failure mode for both groups was fracture of the abutment screw. The results indicate that varying the implant diameter did not compromise the mechanical reliability of the connection.
This study histologically evaluated root resorption and repair in beagle dogs' mandibular premolars after orthodontic intrusion with different force magnitudes. Root resorption was present in all teeth, regardless of applied force. Significant differences were found between root regions, with apices and interradicular regions most affected. Force magnitudes between 50-200g did not show significant differences in amount of resorption. Resorption was most frequent at apices and furcation. The induced root resorption after continuous intrusive forces between 50-200g was not clinically significant.
This study used 3D finite element analysis to investigate the effect of different bone qualities (D1-D4) on stress distribution in an implant-supported mandibular crown. The analysis found that bone qualities D3 and D4 experienced the highest von Mises stresses at the neck of the implant under a 300N load. Placement of implants in bone with greater cortical thickness and density (D1-D2) reduced stress concentration and is more favorable for implant stabilization and osseointegration. However, long-term clinical trials are needed to determine the relationship between bone quality and stress distribution on implant success.

This study used finite element analysis to analyze the biomechanical interactions in alveolar bone surrounding dental implants with smaller-diameter abutments. Twenty models were created that varied the implant position relative to the bone crest, loading direction, and cortical bone thickness. The results showed that loading direction and implant position were the main factors affecting stress distribution in the bone. Models with the implant shoulder placed 1 mm above the bone crest had higher stress values than other positions. Off-axis loading also significantly increased stress values compared to axial loading. The study suggests that implant position and loading direction are crucial for stress distribution in bone.
This study evaluated morbidity after bone graft harvesting from the anterior or posterior iliac crest for maxillofacial and orthopedic procedures. 97 patients underwent either anterior or posterior iliac crest bone harvesting to augment the jaws. Postoperative pain levels were similar for both approaches based on patient questionnaires, with pain decreasing over 6 months. Most patients reported their scars were similar and nearly all would undergo the procedure again, suggesting both approaches provide bone grafts with acceptable morbidity. The posterior approach allows harvesting of larger amounts of bone.
This research article analyzes the biomechanical behavior of a virtual model of the mandibular bone loaded with monophasic and biphasic dental implants through finite element analysis (FEA). The purpose is to evaluate the biomechanical differences between monophasic and biphasic implants and assess their proper clinical use. The FEA shows that the stress distribution on the bone crest is different for the monophasic and biphasic implant configurations. Specifically, the case with the monophasic implants shows a maximum stress slightly higher than the biphasic implant case. However, the stress distribution on the mandibular ridge appears more uniform for the monophasic implant case.
Classification of sagittal root position in relation to the anterior maxillar...droliv
This study aimed to classify the relationship between the sagittal root position of maxillary anterior teeth and their osseous housings using cone beam computed tomography scans. The scans of 100 patients were reviewed and the sagittal root positions were classified into 4 categories. The results showed that 81.1% were classified as having the root against the labial cortical plate, 6.5% in the middle of the housing, 0.7% against the palatal plate, and 11.7% engaging both plates. An understanding of sagittal root position provides useful information for treatment planning immediate implant placement and provisionalization.

This study evaluated the influence of finishing and polishing procedures on the decision to replace existing amalgam restorations. Twenty amalgam restorations from 6 patients were photographed before and after being polished. 27 clinicians and students reviewed the before and after photos and indicated whether replacement was needed. Before polishing, 44% of restorations were deemed replaceable, but after polishing this decreased significantly to 21%, with secondary caries being the main reason for replacement. The study concluded that finishing and polishing reversed the decision to replace many old amalgam restorations.
This technical note describes an arthroscopic technique for addressing both a rotator cuff tear and a cyst within the greater tuberosity. The authors debrided the cyst cavity to create a socket, then implanted a resorbable scaffold to provide structure and promote bone ingrowth. This allowed the standard rotator cuff repair to then be performed. MRI at 6 months showed healing of both the cyst and rotator cuff tear. The technique provides a readily available option for surgeons facing this clinical challenge.

This technical note describes an arthroscopic technique for addressing both a rotator cuff tear and a cyst within the greater tuberosity. The authors present a 1-step procedure using porous, resorbable scaffolds to fill the cyst defect at the time of rotator cuff repair. The cyst is thoroughly debrided and a matching implant is placed flush with the bone. Standard rotator cuff repair is then performed. In a 57-year-old patient, MRI at 6 months showed healing of both the cyst and rotator cuff. The technique provides an option for surgeons facing this clinical challenge with minimal additional time or morbidity.

1. The study evaluated the effect of implant shape, length, and diameter on primary stability as measured by resonance frequency analysis.
2. It found that tapered implants had higher implant stability quotient (ISQ) values than parallel implants, and that longer implants had higher ISQ values than shorter implants.
3. Implant diameter also affected ISQ, with wider diameter implants having higher stability than narrower implants. The study concluded that tapered implant shape, longer length, and wider diameter can provide better primary stability.
This document provides an overview of the history and evolution of anterior cruciate ligament (ACL) reconstruction techniques. It discusses early techniques from 1919 using fascia lata and tendon grafts with poor results. Improved techniques emerged in the 1960s-1970s using tendon grafts with better fixation. The use of hamstring and patellar tendon grafts became more common from the 1980s onward. Recent developments include anatomic double bundle reconstruction and the use of allografts. The document also reviews the biology, mechanical properties, fixation methods, rehabilitation considerations, and potential complications of different graft options used in ACL reconstruction.
The document presents a geomechanical wellbore stability model developed for an exploratory well in Colombia's Middle Magdalena Basin, which uses linear elastic theory, well log data, and laboratory tests to estimate mechanical properties and stress states. The model was calibrated using data from previously drilled wells and validated during drilling of the exploratory well. Developing this model allowed the company to formalize its geomechanical modeling methodology in Colombia.
This document discusses treatment options for edentulous patients in the mandible, including conventional dentures, tissue-borne implant supported prostheses, and implant-supported prostheses. It describes in detail the procedures for placing 2, 4, or 5 implants to support overdentures or fixed prostheses. Placement of implants can help patients regain function and confidence by stabilizing dentures or providing a fixed solution.
Numerical Investigation on the Stability of an Underground Mine Opening in ...Premier Publishers
The stability of an underground opening is an essential factor in the mine operation; the proper prediction of the stability is mandatory for the optimum support design and smooth mine operation. Previous researchers have identified the presence of pre-existing natural fractures as a critical factor for the stability of subsurface opening. However, the variation of natural fracture impact due to different fracture parameter value is yet to be identified. Fracture intensity, orientation, and opening are the most dominant parameters that determine the magnitude of the impact on stability. This study has built an underground mine tunnel model using Itasca’s software 3DEC and analysed the sensitivity of the aforementioned essential parameters. Moreover, the built model has been analysed for varying fracture density, orientation, scaling exponent and distribution and the corresponding displacements of the tunnel in different directions are simulated. The outcome of this study is helpful for the prediction of the mine opening stability and the optimization of support system design.
Split Pectorales Major and Teres Major Tendon Transfers for Reconstruction of...Peter Millett MD
Isolated ruptures of the subscapularis and anterosuperior rotator cuff lesions are encountered more rarely than supraspinatus or anteroposterior rotator cuff tears. In certain circumstances, reconstruction of the tendon may not be possible due to fatty degeneration and atrophy of the subscapularis muscle or poor tendon quality. Tendon transfer may represent the only surgical option for treatment. A pectoralis major tendon transfer is an acceptable salvage option for irreparable subscapularis tendon ruptures. Although limited functional goals may be expected in most cases, the majority of patients obtain a good pain relief, which improves their function below chest level. Addition of the teres major component to the transfer may be beneficial in cases where both the upper and lower portion of the subscapularis muscle is irreparable.

The document summarizes a journal club discussion on autologous chondrocyte implantation (ACI) for treating articular cartilage defects in the knee. It provides details on the ACI procedure, which involves harvesting cartilage cells from a patient's knee, growing them in culture, and implanting them back into the defect using a periosteal patch or collagen membrane. The document compares ACI to other cartilage repair techniques like microfracture and drilling, finding ACI can regenerate hyaline-like cartilage while other techniques only produce fibrocartilage with limited lifespan. Rehabilitation guidelines and long-term assessment of ACI grafts via MRI, biopsy and arthroscopy are also summarized.
THE EFFECT OF CHEMICAL FIXATION ON THE STRUCTURAL PROPERTIES OF HUMAN COLLATE...Dr. Abdurahman Salem
Chemical fixation is commonly used to preserve soft tissues for mechanical testing, but it can alter tissue properties. This study compared the mechanical properties of human knee collateral ligaments that were chemically fixed versus non-fixed. The ultimate tensile strength and structural stiffness of the fixed ligaments were not significantly different than the fresh ligaments. Despite the cross-linking effect of common fixatives like formaldehyde and phenol-formaldehyde, fixation had a negligible impact on the strength and stiffness of the collateral ligaments based on testing of a small number of human specimens.
This document summarizes research from several studies on orthodontics and craniofacial research. It discusses tolerance for deviations in eye and mouth position, using 3D imaging to track facial changes in identical twins over time, examining differences in palate length in fetuses with Down syndrome, measuring friction of different archwire and bracket combinations, evidence of temporary loss of cell membrane integrity during orthodontic tooth movement, identifying growth patterns of the mandibular condyle through molecular and biochemical analysis, and investigating the use of stem cells for craniofacial and dental tissue engineering applications like periodontal and orthognathic surgery.
This document describes a numerical modeling study to predict the strength of St. Peter Sandstone pillars used in underground mining. Finite difference models were created of pillars with dimensions of 12.192 m x 12.192 m x 9.144 m and a room width of 10.3632 m, based on dimensions used successfully in an abandoned Iowa mine. The models applied varying overburden loads to the pillars to determine stress-strain behavior and peak stress. An empirical pillar strength formula was developed and used to establish a relationship between pillar stress, safety factor, and maximum stable overburden depth for factors of safety of 1.5 and 2.
Revision Total Ankle Arthroplasty to Tibial Stemmed Implant: A Case Reportskisnfeet
This case report describes the revision of a failed total ankle replacement (TAR) using two different methods. Initially, the failed TAR was revised using a tibial stemmed implant. However, this revision failed due to infection, requiring a second revision involving removal of the implant and tibiotalocalcaneal arthrodesis with a retrograde nail. While the tibial stemmed implant revision had short term success in other patients, this case demonstrates the difficulty and risk of infection in revision surgeries.
Reliability and failure modes of internal conical dental implant connections ...Marcelo Januzzi Santos .`.
This study evaluated the reliability and failure modes of internal conical dental implant connections supporting maxillary incisor crowns. Forty-two implants from two different manufacturers were tested using step-stress accelerated life testing. Both implant systems had similar reliability and failure modes, with fractures occurring at the abutment-implant connection and screw neck region. The study found no significant differences in reliability or failure modes between the two internal conical implant connection systems tested.
This document discusses methods for measuring implant stability, including resonance frequency analysis (RFA). It provides details on RFA and how it works. RFA involves connecting an adapter to the implant to perform non-invasive analysis of peri-implant bone. RFA measurements are displayed as implant stability quotients (ISQs) from 1-100, with higher numbers indicating greater stability. The document also reviews other measurement techniques such as insertion torque, percussion tests, radiography, and histomorphometry and their limitations.

This study assessed the effects of a chair-side argon-based non-thermal plasma treatment on the surface characteristics and integration of dental implants. Scanning electron microscopy and optical interferometry showed the plasma treatment increased surface roughness and energy levels by removing adsorbed carbon species. X-ray photoelectron spectroscopy confirmed decreased carbon and increased levels of titanium and oxygen after plasma treatment. In a beagle dog model, implants treated with non-thermal plasma for 20 or 60 seconds had significantly higher removal torque values after 2 and 4 weeks of healing compared to untreated implants, indicating improved early biomechanical fixation.

Methods used to_assess_implant_stabilityAsmita Sodhi
This document reviews various methods used to assess implant stability. It discusses that while histologic analysis was traditionally used, less invasive methods are now preferred. It summarizes methods including radiographic analysis, cutting torque resistance analysis, reverse torque testing, modal analysis, and resonance frequency analysis. The document focuses on describing cutting torque resistance analysis and resonance frequency analysis in more detail. It concludes that objective guidelines for assessing implant stability have not been fully established and experience still dominates clinical decisions.
The effect of vibration on the rate of leveling and alignmentEdwardHAngle
This study evaluated the effects of vibration therapy using an AcceleDent device on the rate of orthodontic leveling and alignment in the mandibular arch. The study found that patients who used the AcceleDent device for 20 minutes per day experienced faster leveling and alignment times compared to control groups. For leveling, the AcceleDent group achieved the desired outcome in an average of 160 days, which was 48 and 55 days faster than the study and pre-study control groups respectively. For alignment, the AcceleDent group achieved the desired outcome in an average of 93 days, which was 27 and 38 days faster than the study and pre-study control groups, though the differences for alignment were not
The study evaluated the precision of fit between implant frameworks fabricated using different techniques and implant abutments in a patient simulation model. Three techniques were compared: 1) one-piece cast frameworks, 2) Procera machined and laser-welded frameworks, and 3) laser-welded frameworks. Laser videography was used to measure the gap between bearing surfaces of each framework component and corresponding abutment. The results showed significant differences in precision of fit between techniques, with laser-welded frameworks exhibiting the best fit compared to one-piece cast frameworks.
This document discusses various studies that have compared self-ligating brackets to conventional brackets. Some of the key findings include:
- Studies have found that self-ligating brackets produce significantly less friction than conventional brackets ligated with elastics or metal ties. However, the amount of friction depends on factors like archwire size and bracket design.
- When correcting large misalignments (6mm or more), passive self-ligating brackets were able to generate forces for alignment while conventional brackets did not produce any forces.
- Most studies found no significant differences between self-ligating and conventional brackets in terms of efficiency of tooth movement, alignment times, rates of canine retraction, or anchorage loss. However
This document discusses implant biomechanics and treatment planning considerations for restoring posterior quadrants. It notes that implant restorations must be designed to avoid overload, as excessive loads can lead to bone loss and implant failure over time. Key factors discussed include implant number, length, alignment relative to curves of Spee and Wilson, and linear versus curvilinear configurations. Curvilinear arrangements are emphasized as withstanding more load than linear arrangements due to greater cross-arch stabilization. Case examples demonstrate successful long-term outcomes and failures where biomechanics were not adequately considered.
The document discusses the design of implants for unstable extracapsular proximal femur fractures. It notes the limitations of current implant designs, which fail to provide adequate stability and allow fracture collapse and implant failure. New implant designs need to control factors like bone quality, fracture geometry, reduction quality, implant choice, and placement. Computer modeling is used to simulate fractures, apply cyclic loading, and test the stability of various implant designs, including a proposed new indigenous nail design. The finite element analysis provides data on implant migration and the number of load cycles implants withstand before failure.
The authors wrote a letter to the editor in response to an article on the learning curve associated with using a new cephalomedullary femoral nail. They note several factors that could impact the learning curve that were not addressed, such as using cerclage cables or open surgery for complex fractures. The authors also point out inconsistencies in the reported data on patient characteristics and medical histories, such as bisphosphonate use, that require clarification to properly evaluate the results. The letter aims to provide additional context and perspectives to more fully understand the learning curve analyzed in the original study.
This document discusses implant biomechanics and treatment planning. It notes that implant overload can lead to bone loss and failure if excessive loads are placed on implants during treatment planning. Linear implant arrangements are less predictable than curvilinear arrangements, especially in posterior areas with heavy biting forces. The number of implants, their arrangement, angulation, length, diameter and the quality of surrounding bone all influence the load bearing capacity of implant restorations. Treatment plans must be designed to minimize non-axial forces and prevent implant overload.
This study characterized mini-implant insertion patterns and maximum anchorage forces using CT imaging and tensile testing in human cadavers. Longer implants provided more anchorage but also increased risk of anatomical damage. Maximum anchorage was best predicted by a combination of bone density, insertion depth, and implant length. Variability between cadavers highlights the need to consider individual bone quality. Future work should study dynamic forces and inflammation effects on stability.
This document discusses implant parameters, materials, and digital planning. It summarizes key factors that influence stability including the micro-gap, geometry like platform switching, and biomechanics such as stress distribution. For materials, it evaluates abutments and suprastructures made from titanium, zirconia, lithium disilicate, and other materials. Case examples demonstrate the use of different materials for single crowns, bridges, and full anatomical restorations. Factors like chipping rates, strength, and survival are considered for selecting the optimal restoration material.
This article reviews literature on fracture of dental implants and presents a case report. It finds that implant fracture is a rare but severe complication with multiple potential contributing factors. These include design flaws, poor fit of superstructures, excessive occlusal forces, location in high stress areas like the posterior mandible, small implant diameter, metal fatigue, and bone resorption around implants. The case report describes a titanium implant that fractured after 4 years due to metal fatigue, which was potentially caused by bone loss facilitated by leakage of toxic nickel ions from the implant's non-precious metal crown. This suggests corrosion and ion leakage should be considered a possible risk for late implant fractures.
The document discusses the biomechanics of space closure during orthodontic treatment. It covers topics such as determinants of space closure including axial inclination and midline discrepancies. It also discusses fundamentals of anchorage control including extraoral forces, intermaxillary elastics, and tipping movements. Additionally, it describes strategies for differential space closure such as applying different moment-to-force ratios to anterior vs. posterior teeth. The center of resistance during anterior retraction is also examined.
This document summarizes a literature review on the crown-to-root ratio (CRR) as a factor in evaluating teeth for fixed or removable partial dentures. It discusses that CRR refers to the relationship between the visible crown portion of the tooth above bone compared to the root portion embedded in bone. An ideal CRR is considered 1:1.5 to 1:2. While CRR is one factor, other issues like bone support, mobility, and opposing occlusion must also be considered. The document reviews several studies but notes there is lack of consensus on CRR's influence and that prognosis depends on multiple clinical factors.
The document discusses factors that influence the load bearing capacity of dental implants, including:
1. Curvilinear implant arrangements have the greatest load bearing capacity compared to linear arrangements.
2. Excessively long cantilevers (>20mm) and wide occlusal surfaces can lead to prosthesis failures and implant overload due to increased forces.
3. The trabecular bone structure in the mandible allows it to withstand forces better than the maxilla, making posterior mandibular implants more successful.

1) Understanding the mechanisms of peri-implant bone healing is important as dental implants are increasingly used in more challenging situations.
2) There are differences in how cortical and trabecular bone heal, with trabecular bone healing more rapidly through new bone formation versus cortical bone healing through slower remodeling.
3) Classifying bone as "poor quality" based on its trabecular nature is a misnomer, as trabecular bone is well suited for rapid healing due to its vascular and cellular composition.

O documento descreve um caso clínico de extração de um dente fraturado e inserção imediata de um implante usando o sistema Cone Morse Duocon da Signo Vinces. O implante foi inserido após fresagem do osso, biomateriais foram usados para preencher o defeito ósseo, e um provisório removível foi colocado imediatamente após a cirurgia.
O documento descreve um caso clínico no qual implantes dentários estavam expostos e vestibularizados, levando à perda óssea considerável. O tratamento envolveu o uso de um sistema de tubo-parafuso chamado Micro-UCLA Metálica para corrigir o ângulo dos implantes e mascarar sua exposição, resultando em uma solução reversível, segura e que restaurou a forma, função e estética.
O documento descreve o caso de um paciente que recebeu implantes dentários usando o Sistema Duo - Signo Vinces. Os implantes foram inseridos após planejamento com radiografia e uso de guia cirúrgico. Substitutos ósseos e membrana de colágeno foram usados no sítio. A técnica envolveu incisão conservadora e fresagem com kit cirúrgico. Os implantes apresentaram estabilidade primária e uma prótese provisória foi instalada após 7 dias.
Este estudo avaliou biomecanicamente e histologicamente implantes dentários cilíndricos e cônicos em cães. Os implantes cônicos mostraram valores de torque de remoção significativamente maiores e formação óssea adequada em ambos os grupos nas duas semanas após a inserção. Os resultados indicam que ambas as macrogeometrias promovem a osseointegração inicial, mas os implantes cônicos melhoraram o desempenho mecânico.

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

In response to the urgency and scale required to effectively address climate change, open source solutions offer significant potential for driving innovation and progress. Currently, there is a growing demand for standardization and interoperability in energy data and modeling. Open source standards and specifications within the energy sector can also alleviate challenges associated with data fragmentation, transparency, and accessibility. At the same time, it is crucial to consider privacy and security concerns throughout the development of open source platforms.
This webinar will delve into the motivations behind establishing LF Energy’s Carbon Data Specification Consortium. It will provide an overview of the draft specifications and the ongoing progress made by the respective working groups.
Three primary specifications will be discussed:
-Discovery and client registration, emphasizing transparent processes and secure and private access
-Customer data, centering around customer tariffs, bills, energy usage, and full consumption disclosure
-Power systems data, focusing on grid data, inclusive of transmission and distribution networks, generation, intergrid power flows, and market settlement data

From Natural Language to Structured Solr Queries using LLMsSease
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.
