Summary
Dental schools primarily use enamel modification and cast restorations for removable partial denture abutment preparations. Amalgam, composite, and acid-etched restorations are also common choices.
Area of Science:
- Dentistry
- Prosthodontics
- Dental Materials
Background:
- Removable partial dentures (RPDs) require precise abutment preparations for optimal function and longevity.
- Understanding current trends in abutment preparation is crucial for dental education and clinical practice.
Purpose of the Study:
- To survey dental schools regarding their preferred methods for abutment preparation in RPD cases.
- To identify the most frequently utilized restorative materials and techniques for RPD abutments.
Main Methods:
- A questionnaire was distributed to 58 dental schools globally.
- Data was collected from 43 responding institutions detailing their approaches to abutment preparation for RPDs.
Main Results:
- Enamel modification and cast restorations remain the predominant techniques for RPD abutment preparation.
- Amalgam alloys are widely employed, with composite and acid-etched retained restorations also being utilized.
Conclusions:
- Traditional methods like enamel modification and cast restorations continue to be favored for RPD abutments.
- A range of restorative materials, including amalgam and composite, are incorporated into abutment preparation strategies.
