This prospective study evaluated clinical results of immediately loaded Biomet 3i implants with different surface topographies. Thirty-three periodontally compromised patients received 163 implants (130 in the maxilla and 33 in the mandible; 132 NanoTite and 31 Osseotite). After a mean loading period of 57 months, the survival rate was 96.3%. Mean crestal bone loss was 1.6 mm. No difference in bone loss was detected between the two surfaces. Only 6% of the implants had peri-implantitis based on total bone loss above 2 mm from the day of surgery in conjunction with probing depths of > 4 mm.
这项前瞻性研究评估了不同表面形貌的Biomet 3i即刻负重种植体的临床效果。33名牙周状况不佳的患者接受了163颗种植体（上颌130颗，下颌33颗；132颗NanoTite和31颗Osseotite）。平均负重期为57个月后，生存率为96.3%。平均牙槽嵴骨吸收为1.6毫米。两种表面之间未检测到骨吸收差异。仅6%的种植体在术后当天距种植体2毫米以上的总骨吸收且探诊深度>4毫米的情况下发生种植体周围炎。
