Summary
Achieving complete passivity in implant-supported fixed prostheses is challenging. However, professionals should utilize available technology to ensure an acceptable clinical fit, prioritizing patient biologic, aesthetic, and functional health.
Area of Science:
- Dental Implantology
- Prosthodontics
- Biomaterials Science
Background:
- Implant-supported restorations are widely used in modern dentistry.
- Treatment success hinges on the passive fit of implant-prosthesis components.
- Misfit can compromise the longevity and function of dental implants.
Purpose of the Study:
- To review literature on passivity and misfit in implant-supported fixed prostheses.
- To identify factors influencing passivity and methods for evaluating misfit.
- To discuss the clinical implications of misfit and biologic tolerance.
Main Methods:
- A comprehensive literature search was conducted using the MEDLINE database (PubMed).
- English-language peer-reviewed articles were analyzed.
- Focus areas included acceptable passivity levels, misfit classification, and evaluation methods.
Main Results:
- Complete passivity in implant-supported prostheses is difficult to achieve.
- Various factors influence the passivity of the prosthesis framework.
- Misfit can lead to biologic, aesthetic, and functional complications.
Conclusions:
- While perfect passivity is elusive, striving for an acceptable clinical fit is crucial.
- Technological advancements can aid in minimizing prosthesis misfit.
- Prioritizing patient outcomes requires a focus on biologic tolerance and functional parameters.
