The document discusses occlusal considerations for implant-supported prostheses. It introduces various occlusal terminology and explores the significance of occlusion on osseointegrated implants. The document outlines the goals of implant protective occlusion (IPO), which aims to distribute occlusal forces appropriately to minimize stress on implants and surrounding bone. IPO principles include using thin articulating paper for initial adjustment, equalizing contacts under heavy bite forces, avoiding non-axial and offset loads, and designing the occlusion around the weakest component. The document also discusses factors like implant angulation, crown height, bone quality and the materials used for occlusal surfaces.
This document discusses clinical and laboratory remounting in complete dentures. It begins by introducing complete dentures and the importance of proper occlusion. Errors can occur during the fabrication process that affect occlusion. Remounting procedures, including laboratory and clinical remounting, are recommended to identify and correct occlusal errors. Laboratory remounting involves using a split-cast mounting technique to remount the dentures on an articulator after processing. Clinical remounting takes new interocclusal records in the patient's mouth and mounts the dentures on an articulator to correct errors made during the initial records. Selective grinding is then used to refine the occlusion based on the remount records.
Occlusal Considerations For Implant Supported Prostheses Implant Protectes O...Mohammed Alshehri
Trauma from occlusion refers to pathological changes in the periodontium caused by excessive force from chewing muscles. While excessive force alone does not cause tissue breakdown, it may act as a co-factor in plaque-induced periodontal disease by enhancing the rate of progression. Proper treatment of plaque is important to arrest tissue destruction, even if occlusal trauma persists. Treating occlusal trauma alone through adjustment or splinting may reduce mobility but not stop further breakdown from untreated plaque.
This document discusses occlusal schemes for implants, known as implant protective occlusion (IPO). IPO aims to reduce stress at the implant-bone interface through 14 considerations including eliminating premature contacts, positioning occlusal contacts over implant bodies, reducing cantilever lengths, and decreasing crown heights. The goals of IPO are to reduce force magnification, improve force direction, and increase the implant support area to promote implant longevity and success.

Prosthetic options in implant dentistryNAMITHA ANAND
This document discusses various prosthetic options in implant dentistry. It begins by introducing different treatment options for completely and partially edentulous patients, noting that implant dentistry provides more options compared to traditional dentistry. It then covers Misch's classification system for prosthetic options (FP1-FP3, RP4-RP5), which are determined by the amount of hard and soft tissue replacement needed. The document discusses different prosthesis types for complete and partial edentulism in detail. It also covers considerations for prosthesis design such as crown height space, bone width, implant positioning and restorative materials. In conclusion, the optimal prosthetic option depends on the patient's existing oral condition and treatment goals.
The document discusses different concepts of complete denture occlusion including:
1. Bilateral balanced occlusion aims to limit tipping of dentures during parafunctional movements by having simultaneous contact on both sides in centric relation.
2. Other types discussed are monoplane (neutrocentric) occlusion and lingualized occlusion, which may centralize forces and minimize tipping.
3. Factors like condylar inclination, incisal guidance, cuspal inclination, and compensating curve affect occlusal balance, though research has not shown one occlusion type to be clearly superior.

Implant treatment plan for completely edentulous patientDr. Shashi Kiran
This document discusses classification and treatment planning for completely edentulous patients. It begins by classifying available bone into four categories (A-D). It then classifies edentulous ridges into three types based on bone quality in different regions. Treatment options for the edentulous mandible include removable overdentures (OD1-OD5) supported by 2-5 implants, as well as fixed restorations. The OD options involve placing implants between the mental foramina and adding more implants and connections to improve stability. Fixed options either place implants between the foramina with distal cantilevers or add implants above the foramina to improve support in flexing areas.
INDIRECT RETAINERS IN CAST PARTIAL DENTURESAamir Godil
The document discusses indirect retainers in cast partial dentures. Indirect retainers are components located away from the primary abutment tooth that help control movement of the denture base. They work by resisting rotational movement around the fulcrum line when forces are applied. The most effective location for an indirect retainer is as far from the fulcrum line as possible, typically on a canine or first premolar tooth. In addition to preventing movement away from tissues, indirect retainers can help reduce torque on abutments, stabilize the denture against horizontal movement, and provide auxiliary support to the major connector. Common forms include auxiliary occlusal rests, canine rests, cingulum bars and lingual plates.
This document discusses various types of clasps used for retaining removable partial dentures, including their designs, indications, advantages, and disadvantages. It focuses on clasps suitable for free end saddle cases, explaining how their design and positioning affects forces on abutment teeth during function. Properly designed clasps like the RPA allow rotational movement to relieve destructive torquing forces, while improperly positioned clasps can place torquing forces on teeth. The survey line and centers of rotation are important considerations for clasp design.

This document discusses preventive prosthodontics at the primary, secondary, and tertiary levels. At the primary level, prevention includes oral hygiene, fluoride application, diet counseling, and protective devices like mouthguards. The secondary level focuses on early detection and treatment of issues like occlusal interferences, bruxism, and sleep apnea. Tertiary prevention aims to limit disability through complex treatments, rehabilitation with prosthetics, and carefully timed extractions to prevent ridge resorption.
Attachments in removable partial prosthesishamide norouzi
An attachment is a connector used in removable and fixed prosthodontics that consists of two parts: a female part attached to a tooth, implant, or ridge that acts as a retainer, and a male part attached to the prosthesis. Attachments are classified based on their location, fabrication method, retention mechanism, and degree of movement allowed. Key factors to consider when selecting an attachment include the condition of the abutment teeth and ridge, space available, and the patient's dexterity. Common attachment types include intracoronal, extracoronal, stud, bar, and telescopic attachments.
This document discusses occlusion in removable partial dentures. It outlines several types of occlusion including static and dynamic occlusion. Desirable occlusal contacts are bilateral contacts of posterior teeth in centric occlusion. Methods for establishing occlusion include direct apposition of casts if enough teeth remain, interocclusal records with posterior teeth, or using occlusal rims. The functionally generated path method can also be used to develop a dynamic occlusion record without an articulator. Proper occlusion is important for the success, comfort and longevity of removable partial dentures.
This document discusses different treatment options for edentulous maxillas including fixed prostheses and implant supported/assisted prostheses. It covers patient selection factors like resorption patterns, jaw relations, lip line, sinus anatomy and economics. Minimum implant requirements, biomechanics, complications and different types of fixed prostheses like PFM and hybrid are described. The document also presents a clinical case of an implant supported fixed partial denture.

The document discusses the neutrocentric concept for arranging teeth in complete dentures. The neutrocentric concept proposes using flat teeth without any inclines in any direction to minimize forces that could cause denture instability. The key aspects are using a single flat plane of occlusion parallel to the residual ridges and eliminating cusps and inclines on posterior teeth to direct forces towards the supporting tissues. This concept aims to preserve residual ridge integrity by preventing destructive forces.
Implants can provide support and retention for fixed or removable prostheses. There are various types of implants classified based on location and surgical exposure. Osseointegration is the key mechanism for implant integration with bone. Implants are indicated for fully and partially edentulous patients to improve function, aesthetics and quality of life over conventional dentures. Treatment options include implant overdentures, fixed bridges and single tooth implants. Masticatory performance is improved with implant supported or retained dentures compared to conventional dentures.

This document summarizes key concepts regarding occlusion for implant-supported fixed dental prostheses. It notes that unlike natural teeth which have periodontal ligaments to absorb forces, implants lack this and forces are concentrated at the crestal bone. As such, implant occlusion schemes aim to reduce bending moments and distribute forces axially. Recommendations include using flat fossa and grooves, narrow occlusal tables, reduced cuspal inclines, stiffer materials, and avoiding excursive contacts to protect the implant and surrounding bone.
Dental implants require different biomechanical considerations from natural teeth. Also, with one of the criteria for long-term implant success being “occlusion,” it becomes imperative for the clinician to be well
versed with the different concepts when rehabilitating with an implant prosthesis.
1. The document describes the process of using a digital impression and preliminary jaw relation record to fabricate custom trays (CAD/CAM trays) for making definitive impressions.
2. A digital impression of the edentulous jaws is taken using an intraoral scanner, and a preliminary jaw relation record is made by scanning a jig made of polymerized silicone putty placed between the jaws.
3. CAD software is used to create images of custom trays based on the digital impression and jaw relation record. The custom trays can then be fabricated using 3D printing.

1. Stability in complete dentures is influenced by factors like residual ridge anatomy, quality of soft tissues, impression quality, occlusal planes, tooth arrangement, and contour of the polished surface.
2. Various muscles like the buccinator, orbicularis oris, and mentalis can impact denture stability if the denture borders and contours do not allow for proper function.
3. Establishing balanced occlusion is important for stability, as imbalanced forces can displace the denture during jaw movement.
This document outlines the planning sequence for designing removable partial dentures (RPDs). It begins with a diagnostic assessment and preliminary impressions to obtain diagnostic casts. The casts are then mounted in centric relation. The ideal RPD design is then drawn on paper, considering factors like abutment teeth, the dental arch, and occlusion. The design is surveyed on the study casts to determine the most advantageous path of insertion and withdrawal. The design is then revised and finalized. Key steps in the design process are discussed, including the use of rests, connectors, and different types of retainers for mandibular and maxillary designs. Issues to consider for each component are also outlined.
This document provides an overview of occlusion concepts including:
- Common terminology like centric relation, maximum intercuspation, and anterior guidance.
- Types of occlusion like Dawson's classification, canine protected occlusion, group function occlusion, and balanced occlusion.
- Descriptions of tooth alignment, relationships between dental arches, types of mandibular movements, and occlusal considerations for treatment planning.

This document discusses indirect retainers in removable partial dentures. It defines an indirect retainer as a component that assists the direct retainer in preventing displacement of the distal extension denture base through lever action on the opposite side of the fulcrum line. The functions of indirect retainers are to reduce twisting forces and help stabilize the denture. Factors like fulcrum lines, connector rigidity, and rest effectiveness determine the indirect retainer's effectiveness. Common types include auxiliary occlusal rests and canine extensions. Properly designing indirect retainers based on a patient's dentition can improve the support and stability of a removable partial denture.
A RPD derives support from two main sources periodontally sound natural teeth & residual alveolar processes and associated soft tissues.
A RPD that is supported by healthy natural teeth possesses adequate stability and retention to resist functional displacement.
However, a RPD that is not entirely bounded by natural teeth will move when a load is applied.

The document discusses various concepts of occlusion for fixed partial dentures, including bilaterally balanced occlusion, unilaterally balanced occlusion, and mutually protected occlusion. Bilaterally balanced occlusion aims for simultaneous contact on both sides but is difficult to achieve, while unilaterally balanced occlusion distributes forces to multiple teeth on the working side only. Mutually protected occlusion relies on anterior guidance to prevent posterior contact during excursive movements. The concepts vary in their distribution of forces and indications depending on a patient's needs.
Class II malocclusion results from a protrusive maxilla or retrusive mandible and presents clinically with a distal step, large overjet, and deep bite. Cephalometric findings include a maxillary protrusion or retruded mandible. Early intervention during mixed dentition utilizes a Kloehn facebow to apply orthopedic forces to restrain maxillary growth and distalize the upper dentition into a Class I relationship.
This document discusses open bite, including its definition, classification, causes, and management. Open bite is classified as anterior, posterior, dental/simple, or skeletal/complex. Causes include hereditary factors, environmental factors like mouth breathing, thumb sucking, and trauma. Management depends on the patient's age and involves things like habit control, growth modulation, functional appliances with bite blocks, and sometimes orthognathic surgery. High pull headgear is discussed as a way to control vertical growth.
Class II malocclusion can be intercepted during mixed dentition using a Kloehn facebow to apply orthopedic forces to the maxilla. The facebow restrains maxillary growth and distalizes the upper teeth towards a Class I relationship. Long term effects include maintaining arch width and reducing need for future extractions. The appliance is effective but requires good patient compliance with wear.
1. Class II malocclusion features a distal position of the lower molar or mandible, or protrusion of the maxilla and maxillary teeth.
2. Early intervention with a Kloehn facebow cervical headgear can help intercept growing maxillary excess in the mixed dentition stage.
3. Treatment involves applying orthopaedic forces with the headgear to restrain maxillary growth and distalize the upper dentition into a Class I relationship.

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).

Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

2. The Dorland Medical Dictionary defines occlusion as "closing action" or
"closing state." In dentistry, the relationship between the maxillary and
mandibular teeth during jaw movement and making useful contacts is
called occlusion.
s.farrokhi 2
6. The three occlusal patterns, Included balanced occlusion, Group function, and
mutually protected, can be successfully used for implant-supported restorations.
s.farrokhi 6
7. (Implant protected occlusion) IPO
• Aim
• Changes in conventional occlusion patterns to coordinate with
implant-supported restorations.
s.farrokhi 7
8. Benito et al., In an overview, stated that patients generally divide
into two main and significant groups:
s.farrokhi 8
11. Occlusion of posterior single implant restoration
In this case, the light tapping should be lighter on the
implant's crown than on the adjacent teeth.
s.farrokhi 11
12. Occlusion of posterior single implant restoration
Under heavy clenching in MIC or CO mode, contact on
the implant and the tooth is similar
s.farrokhi 12
13. Occlusion of posterior single implant restoration
In lateral eccentric movements, the posterior single implant restoration should
not be placed on the loading to reduce the possibility of horizontal force on the
implant.
s.farrokhi 13
14. Occlusion of posterior single implant restoration
In the protrusive movement, the anterior teeth play a guidance role, and the
posterior implant should be completely discluding.
s.farrokhi 14
15. Occlusion of anterior single implant restoration
• Under the light force of the anterior single implant restoration, they should not have any contact.
Under heavy pressure, the contact on the single anterior implant should be similar to the
adjacent tooth. Still, in the eccentric movements, the anterior single implant restoration should
be entirely out of contact.
s.farrokhi 15
16. Occlusion of anterior single implant restoration
• Adjustment of occlusion of a single unit of canine teeth is similar to a single implant of the
anterior teeth. A single canine implant should not use in eccentric movements, except in special
situations such as class 2 patients. Other adjacent teeth should also be used in the anterior
guidance. First, the lateral tooth, and then the detachment is the premolars.
s.farrokhi 16
17. Supported occlusal design with anterior and posterior implants
• Kennedy classification class 4:
• There should be no contact with the implant-supported anterior bridge in MIC, and the posterior
natural teeth should bear the force. If the natural tooth has good support, group function or
canine guidance is suitable. If possible, this restoration should be out of occlusal contact in all
eccentric movements.
s.farrokhi 17
18. Supported occlusal design with anterior and posterior implants
• Kennedy classification class 3:
• There is gentle contact under light force on the implant segment and under heavy pressure on the
implant, and tooth restoration is similar. There should be no contact with the implant restoration
in a protrusive and eccentric movement. And the anterior guidance is created on the natural
tooth.
s.farrokhi 18
19. Supported occlusal design with anterior and posterior implants
• Kennedy classification class 2:
• In the MIC or CO under the implant restoration's gentle contact force so that natural teeth can be
intruded. In heavy occlusion, simultaneous contact between the tooth and the implant must
occur to uniform the force distribution.
• When the posterior restoration is opposite the implant support, there should be no contact under
the gentle force, but in heavy contact force bed on the implant restoration is similar to other
teeth.
• In eccentric movement, Any contact should be avoided
s.farrokhi 19
20. Supported occlusal design with anterior and posterior implants
• Kennedy classification class 1:
• Under low to medium intensity force in MIC, contacts on posterior implants and with mild
intensity on anterior teeth.
• In lateral eccentric movements, the natural anterior teeth should guide and separate the
posterior portion.
s.farrokhi 20
21. Occlusal design in eccentric movement Occlusal design in MIC or CR Clinical status
Bilateral balanced occlusion with
lingualized occlusion (in typical ridges)
In severely resorbed ridge: monoplane
occlusion
Under the gentle and heavy force:
bilateral Uniforms contact
Overdenture
Bilateral balanced :If there is a denture in
front of it
If the front arch is toothed, group function
or mutually protected with a shallow
anterior guide
Absence of worker and non-worker
contacts on the cantilever section
Under the gentle and heavy force:
bilateral Uniforms contact
Full-Arch Fixed Implant-
Supported Prostheses
