| Purpose With the development and maturation of dental implant prothesis technology,more and more people choose implant as first restoration.People not only consider the long-term function of implants,but also take esthetic effect into account,especially pay attention to esthetic effect of the maxillary anterior teeth area.To study the osteogenic ability and effect of Bio-Oss & Perio Glas in the peri-implant bone defects of maxillary anterior teeth.Methods 20 cases(12 male,8 female)of anterior teeth trauma are selected from patients treated at Stomatology Dental Implant Center of Anhui Medical University from 2014 to 2016,with a total number of 32 implants,which were selected to graft with two kinds of bone substitutes ‘Bio-Oss & Perio Glas' respectively,with a total number of 32 implants.The permanent crown restoration was performed 6 months after operation.1 year follow-up after operation was made to evaluate the osteogenic ability and effect after implant-supported prostheses through implant survival rate?PES?MBL?width of the labial and palatal bone and satisfaction of the patients.All the patients were required to scan CBCT before operation,after operation,6 months after operation,and 12 months after operation.Results The survival rates were 100%.Soft tissue recovers well and shows no statistical significance in the difference of PES.There was statistical significant difference between two kinds of bone substitutes' changes after operation and 6 months after operation.While it shows no statistical significant difference between 6months and 12 months after operation.Also there was no significant difference in the change of MBL between 6 and 12 months after the operation.Conclusion Bio-Oss and Perio Glas both have good osteogenic ability and effect in the peri-implant bone defects of maxillary anterior teeth.By comparison,it was found that the absorption of Bio-Oss was slow,which was beneficial to the maintenance of width of the labial bone and had a good esthetic effect. |
