Clinical Use of Laser-Microtextured Abutments: A Case Series

Abstract

This article discusses the clinical use of laser-microtextured abutments on dental implant restorations. Four cases are presented, each using one of the four commercially available laser-microtextured abutment styles. Numerous preclinical and clinical studies have shown the positive effects of laser microtexturing on the implant platform in limiting crestal bone loss and benefiting soft tissue stability. Other histologic studies of laser microtexturing on the implant abutment have demonstrated the ability of this specific feature to block epithelial downgrowth and provide a functional connective tissue attachment to the abutment surface. Other abutment designs, styles, and materials have only demonstrated a soft tissue seal with epithelial adhesion and a circular ring of connective tissue fibers around the abutment without direct contact. This article presents clinical and radiographic case examples from a private practice perspective on the longterm successful use of microtextured abutments with respect to crestal bone levels, exceptional soft tissue health, and stability with minimal sulcular depth.

Soft tissue integration of different abutment surfaces: An experimental study with histological analysis

“…A Systematic review (Iglhaut et al., 2014) stated that the micro‐grooved surface could be associated with a longer connective tissue attachment and minor bone resorption around implants. In agreement with these findings, some studies have recently shown that a modified prosthetic abutment surface promotes the creation of a more robust perpendicular collagen fiber attachment to the abutment at the early stage (Nevins et al., 2012a; Nevins et al., 2012b; Shapoff et al., 2016).…”

Influence of Laser‐Microtextured Surface Collar on Marginal Bone Loss and Peri‐Implant Soft Tissue Response: A Systematic Review and Meta‐Analysis

“…After duplicates were discarded, 63 records remained. Review of the titles and abstracts resulted in 22 articles identified as full‐text articles, and seven were excluded for the following reasons: follow‐up <12 months; 44 , 45 redundant studies; 32 LMS design not only in implant neck; 21 , 46 performed with additional surgeries such as hard 47 or soft tissue 48 augmentation. Finally, 15 eligible articles 21‐31,33‐36 were included in this study.…”

Cytocompatibility of Titanium, Zirconia and Modified PEEK after Surface Treatment Using UV Light or Non-Thermal Plasma

“…Abutments as transmucosal parts of an implant are expected to achieve early soft-tissue adhesion, demonstrating good soft-tissue biocompatibility. Modifications of implant abutment surfaces have been the focus of recent research [10,11,12].…”
