Ceramic facet as an alternative to replacing a implant-supported crown in infraocclusion - clinical case
Abstract
Introduction: Scientific evidence has shown us that dental implants do not adapt to the natural eruptive process of the teeth, so over the years they can stand in infraposition in relation to the neighboring teeth, especially when the implants have been placed in patients at the age of growth.
Case Report: In this case report, an alternative is considered to avoid removing the implant-supported crown and having to make a new one by adhering a lithium disilicate veneer. The application of hydrofluoric acid and silane is considered the gold standard for the conditioning of glass ceramics, but it presents high toxicity and is a protocol-sensitive method.
Conclusion: The objective is to propose an alternative for the preparation and conditioning of ceramics based on ammonium polyflouride under absolute isolation. This approach involves returning the patient´s function and aesthetics with a conservative and economical treatment compared to total replacement of the prosthesis.
Keywords: Dental veneers; Ceramic; Ammonium poly-fluoride; Dental esthetics; Dental implants; Hydrofluoride acid.
