Tissue integration of one-stage, nonsubmerged ITI implants over a 5-year period is documented. Fifty-four implants were placed in 38 partially edentulous patients. No implants had detectable mobility after a healing phase of at least 3 months, and there were no clinical signs of peri-implant infection. Radiographs revealed no peri-implant radiolucencies and all implants were in favorable positions for fixed prosthetic restorations. Following completion of the prosthetic treatment, all patients were placed in 3-month oral hygiene recall programs. Annual dental examinations included evaluation of each implant according to fixed criteria. Three years after implant placement, 51 of 53 implants (96.2%) were evaluated as successful (one patient was lost to the study). Acute peri-implant infections were associated with two implants; both were classified as late failures. The results demonstrated that one-stage transgingivally healing ITI implants integrate dependably in the tissue and that successful tissue integration can be maintained for at least 3 years.
记录了5年期的单阶段、非潜入式ITI种植体的组织整合情况。在38名部分牙列缺损患者中植入了54颗种植体。在至少3个月的愈合期后，没有种植体出现可检测到的松动，也没有种植体周围感染的临床迹象。X线片显示种植体周围无透射区，所有种植体位置适合进行固定义齿修复。修复治疗完成后，所有患者都进入了3个月的口腔卫生复诊程序。年度牙科检查包括根据固定标准对每个种植体进行评估。种植后3年，53颗种植体中的51颗（96.2%）被评估为成功（1名患者退出研究）。有2颗种植体发生急性种植体周围感染，均被归类为晚期失败。结果表明，单阶段经龈愈合的ITI种植体在组织中可靠整合，并且成功的组织整合至少可以维持3年。
