Histologic and clinical studies confirm that laser-microtextured implant collars favor the attachment of connective fibers and reduce probing depth and peri-implant 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 bovine-derived 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.
组织学和临床研究证实，与机械加工的种植体颈部相比，激光微纹理种植体颈部有利于结缔组织纤维附着，并减少探诊深度和种植体周围骨丢失。本前瞻性研究旨在评估即刻植入带有激光锁定微纹理颈部并结合骨再生程序的穿黏膜种植体后牙槽骨尺寸的变化。13枚种植体即刻植入单根牙拔牙窝。种植体周围骨缺损用牛源异种骨和可吸收胶原膜治疗。在6个月的再次手术时，激光锁定微纹理颈部为软硬组织附着提供了更有利的条件，并减少了牙槽骨丢失。
