ABSTRACT Histological and clinical studies confirm that laser microtexturing of implant collars favors the attachment of connective fibers and reduces probing depth and peri-implant bone loss, when compared to machined collars. This prospective study aimed at assessing the alveolar dimensional changes after imme- diate transmucosal implants placement (Laser- Lok® microtextured collar) associated with bone regenerative procedures. MATERIALS AND METHODS Thirteen implants (Single-Stage Implant Sys- tem® , BioHorizons, IPH. Inc.) were placed immediately into single-rooted extraction sock- ets. Peri- implant defects were treated with bovine-derived xenografts (Laddec® , BioHori- zons, IPH. Inc) and resorbable collagen mem- branes (Mem-Lok® , BioHorizons, IPH. Inc.). RESULTS At 6-months surgical re-entry, Laser-Lok® microtextured collar provides more favorable OBJECTIVES To assess the clinical, radiographic, and aesthetic outcomes of implants with a laser microtextured collar placed in the anteri- or region of the maxilla at the time of tooth extraction and immediately temporized. METHODS Forty-six Tapered Internal Laser-Lok® Bio- Horizons implants were immediately placed and immediately restored with non functional loading in 46 patients (24 men and 22 wom- en) with a thick gingival biotype, ideal gingi- val level/contour and post extraction intact walls. Survival rate, cortical bone loss and peri-implant mucosal responses were evalu- ated at 6, 12, 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 re-growth mean of 1.8 mm and of 1.5 mm, respectively, was found. The midfacial soft tissue levels showed 0.12 mm of mean recession after 24 months. CONCLUSION Immediate implants with a laser microtex- tured surface restored at the day of surgery, may be considered a predictable procedure in terms of implant survival and hard and soft tissue remodeling. conditions for the attachment of hard and soft tissues, and reduces the alveolar bone loss.
