Study Notes
Introduction to Prosthodontics
- Prosthodontics focuses on artificial replacements for missing body parts, particularly in dentistry.
- Involves diagnosing, planning treatment, and maintaining oral function and aesthetics for patients with missing teeth or maxillofacial tissues.
- Prosthesis refers to any artificial replacement, while dental prosthesis specifically addresses teeth and associated structures.
Definitions and Types of Dentures
- Partial Denture: Restores one or more teeth but not the entire arch; can be removable or fixed.
- Removable Partial Denture: Can be taken out by the patient; often constructed from durable materials, such as cobalt chromium alloy.
- Fixed Partial Denture (FPD): Secured to teeth or implants, cannot be removed by the patient; suitable for short spans of tooth loss.
Objectives of Removable Partial Denture Treatment
- Improve aesthetics, especially for anterior teeth.
- Restore function in phonetics and mastication.
- Prevent adjacent teeth from shifting or tilting.
- Fill gaps left by missing teeth to prevent atrophy.
- Enhance psychological well-being of patients.
Causes of Tooth Loss
- Dental caries: Leading cause in individuals under 35.
- Periodontal disease: Common in individuals over 35.
- Trauma or accidents: Results in sudden tooth loss.
- Congenital missing teeth: Naturally occurring absence of teeth.
Indications for Removable Partial Dentures
- Situations requiring distal extension or bilateral stabilization.
- Significant loss of residual ridge or questionable prognosis of remaining teeth.
- Immediate replacement post-extraction or for patients under 18.
- Economic considerations play a role in treatment choice.
Fixed Partial Denture Indications
- Short spans with unilateral bounded edentulous spaces.
- Specific Kennedy classifications for effective design.
Dental Implant Therapy
- Dental implants are made of alloplastic materials, inserted beneath the mucosa to support prostheses.
- Not all patients qualify for implants due to various contraindications including unfavorable anatomy and uncontrolled diseases.
Key Terminology
- Diagnostic Cast: Replica of oral structures for treatment planning.
- Denture Supporting Structures: Tissues that support dentures, essential for stability.
- Support, Stability, and Retention: Key concepts for denture functionality, focusing on resistance to displacement.
Types of Dentures and Their Components
- Interim Denture: Temporary prosthesis for aesthetics and function before a definitive solution.
- Abutment: Supporting part of a prosthesis.
- Height of Contour: Greatest circumference of a tooth at a selected axial position.
Concepts in Denture Design
- Undercut: Area below tooth contour, important for prosthesis retention.
- Path of Insertion: Direction in which a denture is placed.
- Guiding Planes: Parallel surfaces on abutment teeth aligning with the insertion path.
- Bounded and Free-End Edentulous Areas: Different classifications of missing teeth areas based on their support.
Treatment Planning and Alternatives
- Treatment plan outlines procedures post-diagnosis for patient care.
- Alternatives to removable partial dentures include fixed partial dentures, implants, or complete dentures.
