“…Subsequent research demonstrated that it would recur after removal of adjacent sulcular epithelium when a laser-microtextured component was replaced. 7,8 Other abutment designs and abutment-implant connections may have a positive effect on limiting crestal bone loss over time. Various histologic studies demonstrate the parallel arrangement of collagen fibers to a variety of abutment surface materials, smooth and machined titanium, gold, zirconia, and other ceramics.9-12 This arrangement creates a circumferential cuff only attached to the abutment by epithelial hemidesmosomes.…”

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.

“…Nevins et al revealed the reintegration of connective tissue after 15 weeks around a laser treated abutment ( 17 , 23 ). Other recent pre-clinical studies showed that when using a standard smooth surface healing abutment an overall superior soft tissue attachment to the abutment surface is achieved by de-epithelializing the crevice and replacing the abutment with a Laser-Lok® one ( 24 ). For this reason, all implants were definitively restored with Laser-Lok® abutments.…”

BackgroundThe goal of the current study is to assess the difference in connective tissue adherence to laser microtextured versus machined titanium abutments.Material and MethodsSix patients were selected and each of them received 2 implants, one combined with a laser treated abutment and one with a machined abutment. After three months, the abutments were retrieved together with their surrounding gingival tissue for histological analysis. Qualitative and quantitative evaluation of microscopical images was performed to assess the presence or absence of adherence between the soft tissues and the abutment, and the percentage of soft tissue adhered to the two different surfaces.ResultsIntimate adherence between connective tissue and the laser treated abutments, while on machined abutments no adherence was detected. A significant difference was found in the percentage of surface in contact with soft tissue between both implant abutments p=0.03.ConclusionsWithin the limitation of the current study, it can be concluded that connective tissues show enhanced adherence to microtextured abutments compared to machined abutments. Key words:Abutment, connective tissue, dental implant, gingiva, human, laser.
