Objective:
This study aims to investigate the bone remodelling and resorption in immediate implantation and restoration of clinical implant-supported overdentures.
Materials And Methods:
Six adult domestic dogs were divided into 2 groups: In the experimental group, 6 implants were immediately placed in each mandible, the distal end implants were inclined distal to the long axis of the tooth at an angle of 30 degrees, and restored immediately. As the control group, the animals underwent immediate implant placement with single denture restoration, respectively, nontilting and tilting at 30 degrees in the long axis of the tooth. The osseointegration index (OI) and rate of bone ingrowth fraction were measured, and the peri-implant bone remodelling was observed. The marginal bone loss was measured in the slices of bone-implant and analyzed.
Results:
New bone regenerated and had remodelled in each group. The experimental group had no statistically significant differences, when compared with other groups, except the tilted implant control group, in terms of the OI and bone ingrowth fraction.
Conclusion:
Obvious bone absorption did not statistically significantly occur in implant-supported overdenture of immediate implant placement and function with satisfactory new bone and OI.
