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.
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.
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.
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.
评估在拔牙时植入上颌前部并即刻临时修复的带有激光微纹理颈部的种植体的临床、影像学和美学效果。
46例患者（24名男性和22名女性），其牙龈生物型厚、牙龈水平/轮廓理想且拔牙后牙槽窝壁完整，即刻植入46颗锥形内部激光锁定BioHorizons种植体并进行无功能负载的即刻修复。在6个月、12个月和24个月时评估种植体存活率、皮质骨吸收和种植体周围黏膜反应。
种植体存活率为95.6%。植入后24个月，近中边缘骨吸收和远中边缘骨吸收的平均值分别为0.58mm（标准差=0.53；范围为0.17 - 1.15）和0.57mm（标准差=0.70；范围为0.42 - 1.10）。近中和远中乳头平均分别再生长1.8mm和1.5mm。24个月后，面部中部软组织水平平均退缩0.12mm。
手术当天植入并修复的具有激光微纹理表面的即刻种植体，在种植体存活以及软硬组织重塑方面可被视为一种可预测的手术方法。
