Abstract：AIM:To study the effects of different repair methods for severe alveolar bone atrophy(RBH≤5 mm) treated with osteotome sinus floor elevation. METHODS:53 patients underwent osteotome sinus floor elevation with bone graft and dental implant for the posterior maxilla area by the same physician.69 dental implants were screw-retained(30) and cement-retained(39)respectively for crown repair.The patients were followed up 1,2 and 3 years after treatment. Im-age data,perioimplants index and satisfaction scores of the patients were evaluated and compared between the 2 groups. RESULTS:The marginal bone loss and apical bone loss were not statistically different between 2 groups.In the 6 points of periodontal depth,5 check points were P>0.05 between 2 groups,except for the distant lingual point(P<0.05). The pa-tients'satisfaction was above 5 scores (between 2 groups, P>0.05). CONCLUSION: For patients with severe alveolar bone atrophy,it is feasible to use the osteotome sinus floor elevation and use screw-retained or cement-retained crown re-pair for the individual patient.
