Summary
This study classifies dental crown and bridge removal systems, offering clinicians guidance for selecting appropriate methods based on clinical situations. It details various removal systems and their applications.
Area of Science:
- Restorative Dentistry
- Dental Materials
Background:
- Dental crowns and bridges have a long lifespan but can fail due to various reasons.
- Removal of temporary restorations is simple, but definitive cast crowns with unknown cements present challenges, often requiring destructive removal methods.
- Conservative disassembly of crowns and bridges can facilitate restorative and endodontic procedures.
Purpose of the Study:
- To classify existing systems for dental crown and bridge removal.
- To describe the mechanisms of various crown and bridge removal systems.
- To provide guidance on the appropriate use of these systems in different clinical scenarios.
Main Methods:
- A comprehensive PubMed search was conducted using keywords related to crown and bridge removal and failure up to January 2010.
- Bibliographies of relevant reviews and articles from key dental journals were manually searched.
- Existing crown and bridge removal systems were categorized based on their mechanisms and applications.
Main Results:
- The study identified various mechanisms and devices for removing dental crowns and bridges.
- A classification system for these removal tools was proposed.
- Information on the application and rationale for using different systems was compiled.
Conclusions:
- A systematic classification of crown and bridge removal systems is lacking in published literature.
- This article provides a much-needed classification to aid clinicians in selecting appropriate removal techniques.
- Understanding and categorizing these systems can improve clinical decision-making for failed restorations.
