A Comparison of Hydroxyapatite-Coated Micro-Vent and Pure Titanium Swede-Vent Implants
Evian, Cyril I. / Cutler, Susan A.
This article compares the survival rates of two root-form implants- hydroxyapatite-coated (HA-coated) Micro-Vent and pure titanium Swede-Vent implants-during a 6-year period. A total of 390 implants were placed in 166 patients aged 18 to 81 years. Fifteen implants were lost before prosthesis placement, and one was lost after prosthesis loading. The overall success rates were 96.8% for the HA-coated Micro-Vent implants and 95.2% for the titanium Swede-Vent implants. The survival rates were similar for both the maxilla and the mandible and for the anterior and the posterior areas. Although most of the HA-coated implants were generally placed in types 3 and 4 bone, results indicated that the survival rate was similar to that of pure titanium implants, which were placed more often in types 1 and 2 bone.
