Clinical follow-up was conducted on 127 cylindrical implants placed in 21 patients after 5 years of function: 75 implants were coated with titanium plasma spray (TPS) and 52 implants were coated with hydroxyapatite (HA). The aim of the study was to assess possible differences in clinical function and success rates for each implant type. Clinical and radiographic evaluations were conducted, and the periodontal indices of gingival bleeding, plaque, and calculus were measured. Cumulative data were analyzed for differences by implant type and jaw location. No significant differences were found between the 2 implant systems according to the periodontal parameters studied; however, 5-year success rates were 86.7% for TPS-coated implants and 94.3% for HA-coated implants. The periodontal probe index presented abnormal values in the patients with systemic disease and those who were provisionally restored with single-tooth restorations, complete screw-retained dentures, and fixed partial dentures. There were no differences regarding implant placement when mandibles and maxillae were compared. Long-term success rates were outstanding for HA-coated implants and acceptable for TPS-coated implants after 5 years of function. No significant differences were found between the 2 surfaces.
对21例患者植入的127颗圆柱状种植体进行了5年功能后的临床随访：75颗种植体采用钛等离子喷涂（TPS）涂层，52颗种植体采用羟基磷灰石（HA）涂层。本研究的目的是评估每种种植体类型在临床功能和成功率方面可能存在的差异。进行了临床和影像学评估，并测量了牙龈出血、菌斑和牙石的牙周指数。对累积数据按种植体类型和颌骨位置分析差异。根据所研究的牙周参数，在两种种植系统之间未发现显著差异；然而，TPS涂层种植体的5年成功率为86.7%，HA涂层种植体的5年成功率为94.3%。牙周探针指数在患有全身疾病的患者以及采用单颗牙修复体、完全螺丝固位义齿和固定局部义齿临时修复的患者中呈现异常值。比较下颌骨和上颌骨时，种植体植入情况无差异。在5年功能后，HA涂层种植体的长期成功率出色，TPS涂层种植体的长期成功率可接受。两种表面之间未发现显著差异。
