Clinical, radiographic, and esthetic evaluation of immediately loaded laser microtextured implants placed into fresh extraction sockets in the anterior maxilla: a 2-year retrospective multicentric study

Abstract

Objectives: To assess the clinical, radiographic, and esthetic outcomes of implants with a laser microtextured collar placed in the anterior region of the maxilla at the time of tooth extraction and immediately temporized.

Methods: Forty-six Tapered Internal Laser-Lok BioHorizons implants were immediately placed and immediately restored with nonfunctional loading in 46 patients (24 men and 22 women) with a thick gingival biotype, ideal gingival level/contour, and postextraction intact walls. Survival rate, cortical bone loss, and periimplant mucosal responses were evaluated at 6, 12, and 24 months.

Results: Survival rate was 95.6%. Mean mesial and distal marginal bone loss, 24 months after installation, were 0.58 mm (SD = 0.53; range, 0.17-1.15) and 0.57 mm (SD = 0.70; range, 0.42-1.10), respectively. A mesial and distal papilla regrowth mean of 1.8 and 1.5 mm, respectively, were found. The midfacial soft tissue levels showed 0.12 mm of mean recession after 24 months.

Conclusion: Immediate implants with a laser microtextured surface restored at the day of surgery, may be considered as a predictable procedure in terms of implant survival and hard and soft tissue remodeling.
