Classification of sagittal root position in relation to the anterior maxillary osseous housing for immediate implant placement a cone beam computed tomography study
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 document discusses dental implants and the importance of soft tissue and bone health for implant success. It covers topics like osseointegration between implants and bone, gingival shrinkage during healing, the peri-implant soft tissue seal, the need for keratinized gingiva, and maintaining the biological width of peri-implant soft tissues. Patient factors like age, smoking, and diseases as well as local bone quality can influence implant success. Proper implant placement and surgical technique are important to support the overlying soft tissues long-term.
Dental implants can replace missing teeth by surgically placing artificial titanium fixtures into the jawbone. There are typically two surgical phases - the initial implant placement and a later surgery to uncover the implant after healing. The implant then receives an abutment and final prosthetic restoration. While dental implants can provide many benefits over other tooth replacement options, there are also potential complications at various stages that a dentist must take steps to prevent and manage. Proper patient evaluation, surgical planning and technique, as well as post-operative care are important to achieve successful long-term outcomes.
This document discusses the classification, etiology, diagnosis, and treatment of infrabony pockets. It defines infrabony pockets as pathological pockets where the base is apical to the alveolar crest. Infrabony pockets are classified based on their morphology and the number of remaining osseous walls. The etiology is often related to factors like tooth anatomy, position, occlusal trauma, and subgingival plaque. Diagnosis involves radiographs and probing to map the pocket. Treatment aims to eliminate signs and symptoms by addressing the etiology, scaling, curettage, and sometimes splinting mobile teeth.
The document discusses gingival curettage, which involves using instruments to remove diseased soft tissue from periodontal pockets. It defines curettage and provides the history of the procedure. The basic technique is described as using curettes to scrape the inner lining of the pocket to remove ulcerated epithelium and damaged connective tissue. Indications include edematous pockets aiming to reduce inflammation and shrink tissue. Healing after curettage is examined through a study showing revascularization of the wound site over time.

They are indicated when tooth mobility impairs function or comfort, while contraindications include poor oral hygiene or insufficient firm teeth for stabilization. The document reviews different splint designs and their advantages of stabilizing teeth, but also notes disadvantages like hindering oral hygiene.
Platform switching involves using a smaller diameter abutment on a larger diameter implant. This shifts the implant-abutment junction inward and away from the crestal bone. According to the document, platform switching reduces crestal bone loss in the following ways: 1) It shifts the inflammatory cell infiltrate inward, decreasing its effect on the crestal bone. 2) It maintains the biological width between the implant and bone. 3) It decreases stress levels in the peri-implant bone by shifting the stress concentration area away from the bone-implant interface. The document discusses the concept, history, advantages, and limitations of platform switching.

This document provides instructions for trying in crown and bridge restorations. It describes evaluating the proximal contacts, marginal integrity, stability, occlusion, and esthetics. For proximal contacts, the contact should be neither too tight nor too loose. Margins should be closed with no more than 50 μm gap. The restoration should be stable without movement. Occlusion should be evaluated for centric and excursive contacts using shim stock or marking materials. Finally, contours, surface texture, and characterization should be evaluated for esthetics.
This document discusses the different types of root resorption, including external root resorption. External root resorption is classified into external surface resorption, external inflammatory resorption, external replacement resorption, and external cervical resorption. External surface resorption is a self-limiting resorption caused by trauma or orthodontic treatment. External inflammatory resorption is often seen radiographically as an extensive lesion caused by necrotic pulp. External replacement resorption replaces the root surface with bone in a process called ankylosis. External cervical resorption is a localized resorptive lesion of the cervical area that may progress in an apical or coronal direction.

Do pre existing micro cracks play a role in the fracture resistance of roots ...Nadeem Aashiq
The document discusses a study that investigated whether pre-existing microcracks play a role in the fracture resistance of non-root filled mandibular incisors. Micro-CT was used to examine 60 teeth for microcracks. Teeth were then subjected to fracture testing. The results showed that 79% of teeth had microcracks, but the number of microcracks only explained 0.65% of the variance in fracture resistance. Most fractures did not correlate with microcrack location or position. The study concluded that there was no clear relationship between the presence of microcracks and fracture resistance of the teeth.
This document provides an overview of trends in endodontic treatment toward a more minimalistic, tissue-preserving approach known as "bio-minimalism." Recent developments discussed include:
1) Advances in instrumentation and imaging technologies like nickel-titanium files, microscopes, and cone-beam CT that improve access and debridement while minimizing tissue removal.
2) Shifting access cavity designs toward greater dentin preservation and a more constrained outline to minimize cuspal flexure.
3) New obturation materials like bioceramics that provide antimicrobial properties and sealing without requiring large tapers or excess removal of inner root structure.
4) Moving beyond traditional concepts to evaluate shifts in protocols based
This case series examines a new surgical technique for regenerating interimplant papillae using subepithelial connective tissue grafts. 10 patients with missing papillae between implant restorations received the new procedure involving buccal and palatal incisions made away from the papilla to preserve blood supply, and tunneling performed with a specialized instrument. The papillae scores improved on average from 0.8 to 2.4 after 16 months, demonstrating regeneration of the papillae over 11-30 months. However, long-term studies are still needed to validate the technique and outcomes.
A new method to mesure mesiodistal angulation and faciolingual with cbctNielsen Pereira
This document describes a new method for measuring the mesiodistal angulation and faciolingual inclination of whole teeth using cone-beam computed tomography (CBCT) images. The method involves digitizing reference points on a typodont's teeth and archwires to define coordinate systems for measuring tooth angles. Measurements using this new CBCT-based method were compared to measurements from a coordinate measuring machine, showing the new method can accurately measure tooth angles. The ability to measure whole tooth angles in 3D from CBCT images could improve orthodontic diagnosis and treatment planning.

Over an average observation period of 28.8 months, the estimated 5-year survival rate was greater than 98.6%. Statistical analysis showed no significant difference in survival rates between implants with abutments angled 0-15 degrees and 20-45 degrees. Good esthetic and functional outcomes were observed.
This document discusses removable partial denture occlusion and articulator selection. It begins by explaining the need for natural and artificial teeth to coexist harmoniously. It then discusses the confusion that exists regarding occlusion despite frequent discussion in literature. Multiple occlusal schemes and articulators are available, and clinicians must consider the individual patient's needs rather than be limited by a single approach. Articulator selection depends on the clinician's experience and the case complexity. Simple articulators are used for limited cases while semi-adjustable and fully adjustable articulators allow for more complex cases and simulation of dynamic jaw movements.
This document discusses factors affecting the selection of patients for implant retained prostheses. It outlines that a thorough patient evaluation including medical history, dental evaluation through examination and imaging, and informed consent is required. The dental evaluation assesses bone quality and quantity, occlusion, and adjacent teeth. Indications for implants include missing teeth from congenital defects, trauma, or being edentulous. Contraindications include certain medical conditions, smoking, drugs/alcohol, or inadequate bone. Proper patient selection is key for implant success and satisfying treatment outcomes.
This document discusses factors to consider when selecting patients for implant retained prostheses. It outlines general patient factors like medical history and motivation that should be assessed. A thorough dental evaluation including extraoral and intraoral exams, various radiographs, and bone density assessment is important. Patients should provide informed consent and understand expectations, risks, and commitments. Clinical indications for implants include missing teeth due to congenital defects, trauma, or being edentulous. Contraindications include conditions that could compromise bone healing or the patient's ability to maintain implants. A multidisciplinary approach may be needed for complex cases.
This document discusses various methods of mixed dentition analysis used to predict the size and space needed for unerupted permanent teeth based on measurements of erupted primary and permanent teeth. It describes Nance analysis, Huckaba's method, Moyer's analysis, Tanaka Johnston analysis, Hixon-Oldfather prediction method, and Staley and Kerber method. The document emphasizes that mixed dentition analysis helps evaluate space availability and plan treatment during the transition from primary to permanent dentition.
Cbct is the imaging technique of choice for comprehensive orthodontic assesmentNielsen Pereira
CBCT is proposed as the imaging modality of choice for comprehensive orthodontic assessment and treatment planning for several reasons:
1) CBCT provides accurate 1:1 geometry which allows for precise measurements and assessments of structures in all three planes of space, unlike 2D imaging.
2) It allows for accurate localization of impacted or ectopic teeth and assessment of root resorption, important factors for developing an effective treatment plan.
3) Features like airway assessment, temporomandibular joint imaging, and periodontal evaluation can be reviewed from CBCT volumes with no additional radiation exposure.

Biomechanical aspects of monoblock implant bridges for the edentulous maxilla...droliv
1) The document discusses biomechanical concepts of occlusion and articulation for implant-supported bridges in edentulous jaws.
2) It recommends using a bilateral balanced group guidance occlusion pattern rather than canine guidance to distribute forces and minimize stress on implants.
3) Temporary bridges placed immediately after implantation can help establish the new guidance pattern before placing definitive bridges.
Treatment of severe sinus infection after sinus lift procedure a case reportdroliv
This case report describes a patient who developed a severe sinus infection after undergoing a sinus lift and grafting procedure. Two weeks postoperatively, the patient reported pain, drainage from the nasal cavity, and yellow mucus discharge from the right nostril. A CT scan revealed thickening of the Schneiderian membrane and scattered graft material, as well as ostium stenosis (narrowing of the sinus opening). Management included endoscopic nasal examination and ostium enlargement by an otolaryngologist, along with antibiotic treatment and full removal of the graft and diseased tissue. The report concludes that the patency of the sinus ostium should be carefully evaluated before sinus lift procedures using CT scans, and otolaryngology consultations
Longevity of teeth and implants a systematic reviewdroliv
This systematic review analyzed 11 studies on tooth loss and 9 studies on implant loss with at least 10 years of follow-up. The incidence of tooth loss varied between 1.3-20% over 10-30 years, depending on the population and maintenance levels. Bone loss around teeth was 0.2-0.8 mm over 10 years. Implant loss varied between 1-18% over follow-up periods ranging from 10-20 years, with bone loss around implants of 0.7-1.3 mm over 10 years. Direct comparisons between teeth and implants were difficult due to heterogeneity between the studies.
Longevity of teeth and implants a systematic reviewdroliv
SUMMARY
This systematic review analyzed 11 publications on teeth with 3,015 subjects and follow-up periods ranging from 10-30 years. The incidence of tooth loss was 1.3-5% in most studies but 14-20% in two studies of rural Chinese populations. The percentage of subjects experiencing tooth loss varied from 25-75%, highest in Chinese populations and untreated periodontitis patients. Bone loss appeared small (<1mm) in well-maintained patients. Nine implant studies with 476 subjects and follow-up up to 20 years found implant loss varied between 1-18%. Bone loss around implants was 0.7-1.3mm in most studies. Comparisons of longevity are difficult due to heterogeneity.
Shouts and whispers an introduction to immunoregulation in periodontal diseasedroliv
This document summarizes current research on immunoregulation in periodontal disease. It discusses how the host immune response, influenced by genetic and environmental factors, determines susceptibility to periodontal pathogens. Key points:
1) The host immune response, particularly the balance between pro-inflammatory Th1 and anti-inflammatory Th2 responses, plays a major role in disease outcome.
2) Cytokines are central to immune communication and determining the Th1/Th2 balance. The roles of IL-1, IL-6, IL-10, IL-11, IL-12, IL-15, and IL-18 in periodontal disease are discussed.
3) Multiple factors can influence the Th1

This analysis characterized adverse events reported to the FDA's MAUDE database after oral and maxillofacial procedures involving recombinant human bone morphogenetic protein 2 (rhBMP-2). The database contained 83 reports of adverse events from 2007 to 2011. Many reports described off-label uses of rhBMP-2, despite some uses and patient populations being contraindicated. The most commonly reported adverse events included local reactions, surgical site infections, graft failure, and wound complications. Over 30% of patients required additional surgery to address adverse events. Graft failure and pseudarthrosis were more commonly reported after off-label uses.

The editorial discusses the influence of bias in implant dentistry research and reporting. It notes that personal preferences can lead to biased perspectives that do not allow for impartial consideration of alternative views. Recent trends have shown an unintended but misguided indirect bashing of early pioneers of osseointegration and their conservative approach. Bias has no place in scientific research and reporting of results, which should objectively present data without reaching conclusions beyond what is supported. A return to fundamentally sound research design and honest reporting of results without bias is needed.
