Effect of laser-microtexturing on bone and soft tissue attachments to dental implants: A systematic review and meta-analysis

Abstract

Background. It is critical to understand laser-microtextured implant collars’ influence on peri-implant pocket depths and marginal bone levels, especially in crucial areas. The present review investigated the peri-implant marginal bone loss (MBL) and pocket depths and failure rates of dental implants with laser-microtextured collars. Methods. An electronic search was run in the PubMed and Embase databases until September 15, 2019. Randomized and prospective clinical studies comparing peri-implant MBL and pocket depths and failure rates between implants with laser-microtextured and machined collar surfaces were included. Five studies (two cohort studies and three RCTs) were included in the meta-analysis after the inclusion and exclusion criteria and qualitative assessments were applied. The risk ratio of osseointegrated implant failure and mean differences in peri-implant MBL and pocket depths were calculated using the Comprehensive Meta-Analysis (CMA) software. Results. Implants with laser-microtextured collars exhibited significantly better marginal bone level scores (P<0.001; MD: 0.54; 95% CI: 0.489‒0.592) and a significant reduction in peri-implant probing depths than implants with machined collars (P<0.001; MD: 1.01; 95% CI: 0.90‒1.13). The assessed studies showed that 17 out of 516 implants failed (3.29%), comprising nine implants with machined (3.62%) and eight implants with laser-microtextured collars (2.98%). However, no significant differences were detected in the implant neck surface characterization (P=0.695; RR: 1.205; 95% CI: 0.472‒3.076). Conclusion. This study suggests that laser-microtexturing of implant collar significantly affected the peri-implant MBL and probing depths. Although no significant differences were noted in implant failure rates between implants with laser-microtextured and machined collar surfaces, the peri-implant MBL and probing depths with laser-microtextured collars were significantly lower than the machined collars.

Tissue-Level Laser-Lok Implants Placed with a Flapless Technique: A 4-Year Clinical Study

“…A recent review reported that the fibro-collagenous attachment around the microgrooved neck might stabilize the bone and reduce crestal bone resorption [ 28 ]. Previous in vitro investigations revealed osteoblast attachment on the laser-microtextured neck and cell alignment along the microgroove directions [ 29 ].…”

Influence of rough micro-threaded and laser micro-textured implant-neck on peri-implant tissues: A systematic review

“…This is because the maxilla and mandible differ in bone quality ( Dank et al, 2019 ). Besides microgrooves, other factors influencing MBL include bone-grafting, placement of implant in fresh alveolar sockets, duration of healing, existing occlusion, angulation of implant, and loading strategy ( Koodaryan and Hafezeqoran, 2021 ).…”

“…The micron-level surface topography promotes more effective interlocking of the bone at the implant interface ( Barfeie et al, 2015 ). In a laser micro-textured surface (LMS) design, a laser ablation technique powered by a computer is applied to the implant neck to achieve 8–12 µm microgrooves ( Chen et al, 2017 , Koodaryan and Hafezeqoran, 2021 ).…”

Custom-Made Composite Shade for Matching an Odd-Shaded Restoration

“…Tooth #9 was extracted under oral conscious sedation with least traumatic technique [15] utilizing Periotomes (BioHorizons, Birmingham, AL, USA), and a 4.6X12mm, 3.5 mm platform implant was inserted (Tapered Internal Plus LaserLok, BioHorizons, Birmingham, AL, USA). This specific implant was chosen to enable "platform switching" [8] along with its LaserLok characterization at the cervical area [10].…”
