Abstract: Objective： To retrospectively evaluate the short-term clinical and radiologic outcomes of a conical bone-level implant with internal hexagonal connection. Methods： A total of 68 conical bone-level im- plants(MIS SEVEN) with internal hexagonal connections inserted into 23 patients were included. Patients were followed up. The survival rate and the marginal bone loss were evaluated by clinical and radiologic examinations. Results： The implant survival rate is 100% within 68 implants. The medial and distal mar- ginal bone loss were(0.02±0.57) mm and (0.14±0.57) mm, respectively, during the average 12.2mouths fol- low-up. Conclusions： High implant survival rate was achieved by this conical bone-level implants with internal hexagonal connections. Marginal bone level was relatively stable. Short-term clinical outcomes were reliable.
