Review of attachments for removable partial denture design: 1. Classification and selection
The International Journal of Prosthodontics
|January 1, 1990
Summary
Dental attachments, mechanical devices for removable partial dentures, are classified by manufacture, location, and flexibility. This review compares them to traditional clasps, aiding treatment decisions.
Area of Science:
- Dentistry
- Prosthodontics
- Biomaterials
Background:
- Removable partial dentures (RPDs) often utilize direct retainers to ensure stability and retention.
- Conventional clasp-type retainers can have esthetic and biomechanical drawbacks.
- Dental attachments offer an alternative direct retainer system for RPDs.
Purpose of the Study:
- To review and classify different types of attachments used in removable partial denture treatment.
- To provide a systematic method for categorizing attachments based on key characteristics.
- To compare the use of attachments with conventional clasp-type direct retainers.
Main Methods:
- Literature review of attachments for removable partial denture treatment.
- Development of a classification system for attachments.
- Comparative analysis of attachments versus clasp-type retainers.
Main Results:
- Attachments are mechanical devices functioning as direct retainers, distinct from clasp assemblies.
- Classification criteria include precision/semiprecision (manufacture), internal/external (location), and rigid/resilient (flexibility).
- Design variations further differentiate attachment types.
Conclusions:
- A comprehensive classification system for dental attachments is presented.
- Understanding attachment characteristics aids in selecting appropriate direct retainers for RPDs.
- Attachments offer distinct advantages and disadvantages compared to conventional clasps.
