Mesiodistal Bone Loss of Fresh Socket Placed Implants and Delay Placed Implants at the Anterior of the Maxilla

Introduction: Immediate implant placement in fresh extraction sockets provides the advantage of shorter treatment time along with minimizing the number of surgical interventions. Materials and methods: Subjects were studied in two groups: in group 1, subjects received a fresh socket placed implant at the anterior of the maxilla and in group 2, a delay placed implant was inserted at the same site. The mesial and distal marginal bone level was measured using parallel technique radiography in time 0, 12, 24 and 36 months after loading. Results: Seventy subjects were studied in two groups. Analysis of the data using a repeat measure test demonstrated the similar bone loss patterns between two groups. Time has a significant effect on bone loss in time 1, 2, 3. The amount of bone loss increased as time passed after loading time. Comparison of bone loss in both groups demonstrated that the amount of bone loss in the central site was more than the lateral site in three measurement times for the group 2 but in the group 1, a significant difference was not observed. Conclusion: Comparison of marginal bone loss in fresh socket placed implants and delay implants did not show a significant difference. Also a continuous bone resorption was observed over the time in the both groups. It may be needed to investigate other success criteria in fresh socket placed implants for making an appropriate treatment plane.
