Posterior Crossbite
Posterior crossbite can be caused by skeletal factors like a narrow maxilla or wide mandible, or dental factors such as teeth erupting in the wrong position. Treatment depends on the cause, but may involve rapid or slow palatal expansion using appliances to widen the maxilla. For skeletal crossbites, expansion appliances are cemented and activated to apply force across the midpalatal suture. For dental crossbites, lighter forces from things like elastic threads or springs are used to move individual teeth. Crossbites caused by jaw shifting are treated by eliminating interferences and expanding a narrow arch. Habit-induced crossbites are addressed by treating the underlying habit. Correcting crossbites early in the
Interceptive orthodontics
This document discusses interceptive orthodontics and serial extraction procedures. It defines interceptive orthodontics as recognizing and eliminating potential irregularities in the developing dentofacial complex.

Impression techniques in removable partial dentures
This document discusses various impression techniques for removable partial dentures. It describes different types of impression materials and trays used for anatomic and functional impressions. Key techniques discussed include the fluid wax technique, McLean's occlusal loading technique, Hindle's finger loading technique, and Rapuno's single tray dual impression technique. The objectives of a corrective or functional impression are to record tissues under loading and distribute forces evenly. Selective tissue placement aims to direct forces to areas better able to withstand stresses while protecting more vulnerable areas.
Jaw relation in rpd
This document discusses the importance of recording jaw relations when fabricating removable partial dentures (RPDs). There are several methods for recording jaw relations, including direct apposition of casts, interocclusal records with posterior teeth remaining, and using occlusion rims. Centric relation should be recorded for distal extension RPDs or when the opposing arch is edentulous, while centric occlusion is preferred when natural teeth can guide the mandible. Proper jaw relation and occlusion are necessary to distribute forces optimally and prevent damage to teeth or bone.
Occlusion In Fixed Partial Denture
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.
11.anterior tooth selection
- Anterior teeth are primarily selected based on esthetic requirements while posterior teeth are selected based on masticatory function and occlusion.
- Factors to consider in anterior tooth selection include morphology, size, color, placement based on anatomical landmarks and guides.
- Careful evaluation of the patient's existing dentition, facial characteristics, and preferences are important in selecting the right anterior teeth.

20.(new)occlusal schemes monoplane-neutrocentric concept
20.(new)occlusal schemes monoplane-neutrocentric conceptwww.ffofr.org - Foundation for Oral Facial Rehabilitiation
1) The neutrocentric concept assumes the plane of occlusion is parallel to the denture foundation and not dictated by condylar inclination, with no vertical overlap or compensating curves.
2) When setting the teeth, the maxillary anteriors are positioned so their incisal edges and the midpoint of the retromolar pads define the flat occlusal plane.
3) Both the anterior and posterior teeth on the dentures are set on this flat occlusal plane with about 1/3 horizontal overlap of the posterior teeth.18.occlusal schemes monoplane with balancing ramps
18.occlusal schemes monoplane with balancing rampswww.ffofr.org - Foundation for Oral Facial Rehabilitiation
This document discusses the monoplane occlusion scheme with balancing ramps for complete dentures. It begins by explaining that monoplane occlusion attempts to minimize tipping forces by reducing inclined plane contacts between the maxillary and mandibular teeth. Balancing ramps are added to counteract forces from Christiansen's phenomenon. The document then provides step-by-step instructions for setting up the anterior and posterior teeth in the maxilla and mandible to achieve the monoplane scheme, including positioning the balancing ramp.Complete dentures 16.occlusal schemes lingualized occlusion

Prosthodontics Procedures and Complications - Posterior Quadrants
Prosthodontics Procedures and Complications - Posterior Quadrantswww.ffofr.org - Foundation for Oral Facial Rehabilitiation
This document discusses prosthodontic procedures and complications in posterior quadrants. It covers topics such as exam and workup, selection of implants, platform switching, abutment selection, provisional restorations, and new technologies like shape memory sleeve abutments. Key points addressed include that no implant design has been proven superior for marginal bone loss, and custom abutments offer better control of margins and occlusal thickness than prefabricated abutments. New technologies aim to simplify procedures and improve retrievability of restorations.Single tooth
This document discusses single tooth defects in the posterior quadrants and their restoration. It compares fixed dental prostheses to implants, noting that implants are generally preferred when adjacent teeth are healthy or nearly so. For endodontically treated teeth, a fixed restoration is preferred if sufficient tooth structure remains and occlusion and parafunction are minimal. Considerations for implant placement include anatomic factors, timing of placement, and prosthodontic issues like abutment selection and cement versus screw retention. The goal is to restore function while avoiding complications like fracture, overload, and peri-implantitis.
Restoration of posterior quadrants
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.
Implants and rp ds
This document discusses the use of implants to supplement removable partial dentures (RPDs) in various clinical situations. Implants can be used to improve support, stability, and retention of RPDs when existing dentition is compromised. Common scenarios include using implants in extension base RPDs, with questionable implant anchorage or unfavorable configurations, to replace lost implants in key locations, replace a lost natural tooth abutment, or supplement insufficient existing dentition. Resilient attachments are often used to retain implant-assisted RPDs while avoiding implant overload. Complications can include peri-implantitis, loose abutments, and wear of attachments. Overlay RPDs are also discussed as an option to
Computer guided
This document discusses computer guided treatment planning and implant placement. It describes how computer guided planning allows visualization of potential implant sites in 3D and more precise placement compared to free-hand drilling. Fully guided surgery uses surgical templates to control position, angle, depth and diameter of osteotomies, while semi-guided surgery controls initial position and angle only, allowing more flexibility. Fully guided is used for edentulous patients, while semi-guided is preferred for partially edentulous patients where soft tissue manipulation or bone grafting may be needed.
Angled implants
This document discusses dental implants, specifically angled (tilted) implants used to restore edentulous maxillas. It describes several approaches for using tilted implants, including placing 4-6 implants with angled abutments to offset the implant angles, or using co-axis implants where angulation correction is subgingival. Tilted implants provide advantages like longer distal implants, improved primary stability, and eliminating the need for sinus augmentation. Studies show success rates above 90% for tilted implants.
Restoration of endodontically treated teeth
Restoration of endodontically treated teethwww.ffofr.org - Foundation for Oral Facial Rehabilitiation
Crowns significantly improve the success of endodontically treated posterior teeth but do not improve the success of anterior teeth. Posterior teeth require crowns more often than anterior teeth due to greater cuspal deflection after root canal treatment. The main purpose of a post is to retain a core, not strengthen teeth. Posts should extend to retain 5mm of gutta percha and not exceed 7mm in molars. The diameter of posts should not exceed one-third of the root diameter and range between 0.6-1.2mm. A ferrule of at least 2mm helps prevent tooth fracture.Provisional restorations
Charles J. Goodacre presents on provisional restorations in fixed prosthodontics. He discusses the functions and requirements of provisional restorations including protection, mastication, esthetics, positional stability, and providing diagnostic information. He describes various provisional restoration resins and their properties. Goodacre also outlines different types of provisional restorations including prefabricated, custom-fabricated, direct and indirect techniques. He demonstrates techniques for direct provisional restorations using templates and indirect restorations fabricated by a laboratory.
Secondard impression materials
This document discusses secondary impression materials used in fixed prosthodontics. It defines an impression as a negative reproduction of prepared teeth that provides information to fabricate a crown or fixed prosthesis. Impressions can be physical materials or digital scans. Physical impressions include reversible hydrocolloid, condensation silicone, polysulfide, polyether, and addition silicone. Custom trays are often used and are fabricated from autopolymerizing or light-cured resin. Ideal impressions accurately record all prepared surfaces and maintain dimensional stability until the laboratory casts are made.
Fluid control and tissue managemtent
This document discusses techniques for fluid control and tissue management during fixed prosthodontic impressions. It describes the need to displace gingiva to record tooth structure below the finish line. Various methods of fluid control are outlined, including retraction cords, suction, and isolite systems. Retraction cords should be moistened with hemostatic agents before gentle placement to displace tissue. The document recommends a two-cord technique using different diameter cords and additional hemostatic agents if needed to control bleeding and produce accurate impressions. Proper fluid management is essential for high quality fixed prosthodontic impressions.
Ceramics in fixed prosthodontics considerations for use in dental practice
Ceramics in fixed prosthodontics considerations for use in dental practicewww.ffofr.org - Foundation for Oral Facial Rehabilitiation
This document provides an overview of ceramics used in fixed prosthodontics. It discusses various types of ceramics including glass ceramics, glass infiltrated mixtures, and polycrystalline ceramics. Examples mentioned include lithium disilicate, zirconia, and alumina. The document reviews clinical indications and uses of different ceramics, as well as case considerations, preparation designs, and causes of failure. An outline is provided of the topics to be covered in the presentation on ceramics in dental practice.Dental cements and cementation procedures
1) There are two main hardening mechanisms for dental cements - acid-base reactions and polymerization reactions. Common cements that use acid-base reactions include zinc phosphate, polycarboxylate, and glass ionomer cements. Resin cements use a polymerization reaction.
2) Zinc phosphate cement has a long history of success but lacks adhesion and fluoride release. Polycarboxylate cement bonds to tooth structure and has short mixing/working times. Glass ionomer cement releases fluoride and bonds to tooth structure.
3) Resin-modified glass ionomer cement combines the benefits of glass ionomer cement with the strength and handling of resin, providing good early strength and reduced moisture sensitivity.
Single tooth defects in the posterior quadrants
Single tooth defects in the posterior quadrantswww.ffofr.org - Foundation for Oral Facial Rehabilitiation
1. Single tooth defects in the posterior quadrants can often be restored with either fixed dental prostheses or dental implants, depending on the clinical situation and anatomical factors.
2. Implant placement can be immediate, delayed, or staged depending on factors like infection, bone quality, and proximity to anatomical structures.
3. Site enhancement procedures may be needed to augment bone in order to place implants in ideal positions and ensure adequate bone volume.Dental implants cement retention vs screw retention
Dental implants cement retention vs screw retentionwww.ffofr.org - Foundation for Oral Facial Rehabilitiation
This document discusses cement retention versus screw retention for dental implants. Both methods can be used if done properly. Cement retention is simpler but risks residual cement being left under gums, which can lead to peri-implantitis. Screw retention allows easy removal but requires access holes. Residual subgingival cement is the major problem, as it is difficult to fully remove and can cause inflammation and bone loss over time.12.resin bonded prostheses
This document summarizes research on the success rates and complications of resin bonded prostheses (RBPs). It finds that on average, 26% of RBPs experience complications within 4 years, increasing to 28% after 5 years, with debonding being the most common at 21%. Debonding rates are higher for posterior teeth, longer spans, and cantilever designs. Tooth preparation techniques like covering lingual and proximal surfaces, adding proximal grooves or pinholes, and occlusal rests can reduce debonding. Maintaining a minimum of 0.5mm occlusal clearance and 1mm metal thickness also impacts success. Proper diagnosis, treatment planning and cementation techniques are keys to optimizing longevity
11.tp & fpd designs
This document is a lecture on fixed partial denture (FPD) designs by Charles J. Goodacre from Loma Linda University School of Dentistry. The lecture discusses key considerations for FPD treatment planning including tooth stability, occlusal forces, abutment selection, and material choices. It provides examples of different FPD designs for single and multiple tooth replacements in the maxilla and mandible. Challenges with each case such as cantilevers, oral hygiene access, and risk of failure are evaluated. The goal is to create the best online programs of instruction in prosthodontics.
10.rest rct
Crowns significantly improve the success of endodontically treated posterior teeth. Posts are primarily used to retain cores and do not strengthen teeth. The appropriate post length is to extend to the radiographic apex with 5mm of gutta percha retained. Post diameter should not exceed 1/3 of the root diameter and range from 0.6-1.2mm. A ferrule of at least 2mm is recommended to prevent root fracture.
9.dental cements
This document discusses various dental cements and cementation procedures. It describes the compositions, characteristics, and mixing procedures of different cement types including provisional cements, zinc phosphate cement, polycarboxylate cement, glass ionomer cement, resin-modified glass ionomer cement, resin cement, and calcium aluminate cement. It also outlines various clinical procedures for cementation such as provisional crown removal, tooth preparation, crown placement, adjustment, and cement cleanup.
