Abstract

Implant abutments are artificial devices that are connected to the dental implants after the healing process is over. The abutments are used to attach a crown, bridge, or removable denture to the implant fixtures. Accurate prosthodontic rehabilitation is the key factor for providing the long-term success and the survival of osseointegrated implants. A precise fit of the implant is crucial since microgaps at the implant–abutment interface allow for microbial colonization, which can lead to peri-implant tissue inflammation. Polyetheretherketone (PEEK) has been used for academic investigations and commercialization of several dental devices, such as dental implants, abutments, healing caps, orthodontic braces, and most notably denture prosthetic frameworks. Keywords: Implant Abutment, PEEK, CAD/CAM, Emergence profile.

Highlights

The prosthodontist’s ability to conceptionalize the end result of treatment and to envision the final prosthesis in the space of the oral cavity is a major clinical asset in planning and placing the prosthetic anchors in bone
Once an implant is well integrated with the surrounding bone, its long-term success is heavily dependent on restorative biomechanical factors
The oral microbial flora attachment to PEEK abutments is comparable to those made of titanium, zirconia and polymethylmethacrylate.[17]

Summary

Introduction

The prosthodontist’s ability to conceptionalize the end result of treatment and to envision the final prosthesis in the space of the oral cavity is a major clinical asset in planning and placing the prosthetic anchors in bone. Metal or plastic Abutment: These abutments are used following exposure of the implant platform and prior to the final restoration They are used in the provisional phase and help to customize the form, shade, soft tissue profile and the occlusion prior to the definitive restoration. The TiN coating covers the entire abutment except for the contact area between the abutment/ implant and screw/abutment This type of titanium abutment is ideal for esthetically challenging cases with thin soft tissue or when using an all-ceramic crown. Because of titanium’s unique physical properties, titanium abutments are the first choice for posterior implants These abutments are available as prefabricated stock or CAD/CAM milled customized abutments.[15] Fig. 3.
