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.
