Summary
Full coverage restorations (FCRs) impact periodontal health. Successful FCRs restore function without harming biology, requiring careful execution of all treatment phases, not just marginal placement.
Area of Science:
- Dentistry
- Periodontology
- Prosthodontics
Background:
- The placement of full coverage restoration (FCR) margins relative to the gingival crest has been debated for decades.
- Focus has often been on mechanical aspects like marginal fit and configuration.
- Periodontal health is crucial for restorative success.
Purpose of the Study:
- To review the scientific evidence on full coverage restoration margin placement and its effect on periodontal health.
- To highlight that restorative success depends on biologic adaptation and function restoration, not solely marginal design.
Main Methods:
- Literature review of scientific evidence.
- Analysis of factors influencing periodontal health in relation to FCRs.
Main Results:
- Marginal quality and fit are important but insufficient for periodontal health.
- Successful FCRs must restore masticatory system form and function without adverse biologic impact.
- Biologic adaptation must be respected throughout all technical phases of treatment.
Conclusions:
- Periodontal health is paramount for successful full coverage restorations.
- A holistic approach considering all treatment phases and biologic limits is essential for FCR success.
