USE OF CUSTOM ABUTMENTS IN PROSTHETIC TREATMENT WITH IMPLANT-SUPPORTED RESTORATIONS

Abstract

Today, implantation surgery allows for a predictable result in the rehabilitation of patients with partial or complete absence of teeth. Modern technological capabilities allow dentists and dental technicians to use numerous approaches to the choice of materials, ways of manufacturing individual abutments and their final design. However, there is no definitive protocol for the selection of all components of the structure. The purpose of this study was to review the literature on the mechanical and aesthetic results of using customized implant abutments in the replacement of dentition defects with implant-supported prosthetic structures. A literature search was conducted using the PubMed electronic database using the search term "custom abutment". The search period covered the period from January 2012 to December 2022. The final review included 32 articles. The review of current scientific sources provided preliminary evidence that in most cases, the use of customized implant abutments makes it possible to perform predictable restoration of function in patients with missing teeth. At the same time, dentists have a wide range of materials in their arsenal to achieve highly aesthetic results without significant compromise in mechanical performance compared to classic titanium abutments. Further modernization of approaches to the standardization of the manufacture of individual abutments is likely to lead to the everyday use of such structures not only in areas of the oral cavity where the requirements for aesthetics are increased to the maximum, but also to their use in other situations.
