Objective To provide basis for cl inical appl ication of ANKYLOS dental implants by following up alveolar bone status of 318 pieces of restored ANKYLOS dental implants. Methods Between February 2008 and August 2009, 170 patients with dentition defect underwent placement of ANKYLOS dental implants (318 pieces). There were 74 males (133 pieces) and 96 females (185 pieces) with an average age of 43.8 years (range, 23-68 years). After operation, the periapicalX-ray films were taken to observe osseointegration around the neck of implant, alveolar bone resorption, and survival ofimplants. Results All patients were followed up at 6, 12, and 24 months after operation. There were 9 failure implants witha total dental implants survival rate of 97.17% (309/318): 3 at 6 months, 4 at 6-12 months, and 2 at 12-24 months, showing no significant difference in dental implants survival rate among 3 time points (χ2=0.470 3, P=0.492 8). New bone formed around the neck of implant in 4 cases at 6 months and in 31 cases at 12 months; at 6, 12, and 24 months, the bone increase was (0.392 7 ± 0.217 4), (0.633 5 ± 0.202 1), and (0.709 0 ± 0.199 1) mm, respectively, showing significant differences among 3 time points (P lt; 0.05). At 6, 12, and 24 months after operation, the bone loss of other patients was (0.392 7 ± 0.217 4), (0.716 7 ± 0.220 3), and (0.723 2 ± 0.215 4) mm, respectively, showing significant differences among 3 time points (P lt; 0.05). Conclusion After restoration with ANKYLOS dental implant, alveolar bone status is good and the implant success rate is high during short-term follow-up. But further observation and study are required for long-term effectivness.
