Study Notes
Dentistry
- Encompasses the study and application of measures designed to prevent deterioration of the oral structures.
- Focuses on improving oral health through clinical procedures.
- Aims to relieve pain, treat oral disease, maintain masticatory efficiency, and restore esthetics.
Prosthesis
- Artificial replacement of a missing body part.
Prosthodontics
- Branch of dentistry concerned with restoration and maintenance of oral function, comfort, appearance, and health.
- Achieved through restoration of natural teeth or replacement of missing teeth and tissues with artificial substitutes.
- Two categories: removable and fixed.
Removable Prosthodontics
- Deals with replacing teeth and structures for edentulous or partially edentulous patients with removable substitutes.
Fixed Prosthodontics
- Concerned with restoration or replacement of teeth with non-removable artificial substitutes.
Crown
- Artificial replacement restoring missing tooth structure, surrounding the remaining structure with materials like cast metal, porcelain, or combinations.
- Aims to reproduce form and function of the tooth and potentially enhance appearance.
- An extracoronal restoration.
Full Veneer Crown
- Covers all surfaces of the clinical crown.
- Can be made entirely of metal, all porcelain, or a metal-ceramic combination.
Partial Veneer Crown
- Restores only a portion of the clinical crown.
Three-Quarter Crown
- Partial coverage cast crown that restores occlusal surfaces and all axial surfaces except the facial surface.
- Retained by grooves prepared on the proximal surfaces.
Reversed-Three Quarter Crown
- Modified ¾ crown with buccal surface prepared instead of the lingual surface.
One-Half Crown
- Partial coverage cast crown involving mesial surface, mesial halves of buccal and lingual surfaces, and half of the occlusal surface.
- Retained by buccal and lingual grooves.
Seven-Eighth Crown
- Extension of the three-quarter crown including a major portion of the facial surfaces, usually the disto-buccal cusp.
- Retained by buccal and mesial grooves.
MacBoyle Retainer
- Modified three-quarter crown with retention from two grooves at the labio-proximal line angles.
- Indicated for mandibular anterior teeth.
Pin-Ledge Retainer
- Partial coverage restoration retained by two ledges and three pins, two incisally and one gingivally.
Temporary Crown
- Crown made and used temporarily to protect the prepared tooth until the permanent crown is completed.
Intracoronal Restorations
- Replace missing tooth structure within the crown of the tooth.
Inlay Retainer
- Intracoronal cast restoration that restores proximal and occlusal surface of the tooth without covering the cusp.
- Used to support occlusal rest in fixed-supported bridges.
Onlay Retainer
- Modification of the inlay with cusp overlay on the occlusal surface to protect the integrity of remaining tooth structures.
