Soft and Hard Tissue Modifications at Immediate Transmucosal Implants (with Laser-Lok Microtextured Collar) Placed into Fresh Extraction Sites: A 6-Month Prospective Study with Surgical Reentry

Histologic and clinical studies confirm that laser-microtextured implant collars favor the attachment of connective fibers and reduce probing depth and periimplant bone loss when compared with machined collars. This prospective study aimed at assessing the alveolar dimensional changes after immediate placement of a transmucosal implant with a Laser-Lok microtextured collar associated with bone regenerative procedures. Thirteen implants were placed immediately into single-rooted extraction sockets. Peri-implant defects were treated with bovinederived xenografts and resorbable collagen membranes. At 6-month surgical reentry, the Laser-Lok microtextured collar provided more favorable conditions for the attachment of hard and soft tissues and reduced the alveolar bone loss.
