Achieving ideal esthetics in osseointegrated prostheses. Part I. Multiple units
This article describes two new abutments that are intended to enhance the esthetics and function of the implant prosthesis while keeping it in harmony with the periodontium. Part 1 discusses the EsthetiCone, designed for use with multiple-unit restorations, which allows subgingival placement of porcelain for maximal esthetics. Unlike traditional abutments, the EsthetiCone is placed 4 to 6 weeks after the fixture is uncovered. Therefore, the size and type of abutment are chosen by the restorative dentist, rather than by the surgeon. Guidelines for abutment selection and placement are provided in this paper.
