Influence of Implant Component Materials on Peri-Implant Soft Tissue Healing: A Comparative Histological and Immunohistochemical Study in Humans.

Background: Recently, the importance of peri-implant soft tissue integration quality has been recognised as an essential factor in the long-term success of dental implant rehabilitation.

Aim: The aim of this study was to explore the influence of three materials commonly used in implant dentistry, namely titanium (Ti), dental adhesive resin (Re) and polyetheretherketone (PEEK), on the peri-implant soft tissues.

Methods: In this clinical randomised comparative study, 37 bone-level implants were placed, and experimental transmucosal healing abutments made of different materials were randomly assigned to each implant.

Clinical and radiographic assessment of circular versus triangular cross-section neck implants in the posterior maxilla: Five-year follow-up of a randomized controlled trial.

Objectives: Dental implants with a triangular neck design have been developed in order to maintain peri-implant bone. The primary aim of this randomized controlled trial (RCT) was to assess after 5 years the peri-implant bone stability and the peri-implant soft tissue conditions with this new triangular implant neck design compared to a conventional round neck implant design.

Material And Methods: This is a secondary evaluation of a RCT including 34 patients.
