Abstract

Objectives :
The aim of this study was to evaluate clinically and radiographically alveolar Bone dimensional Changes after flapless immediate implant placement.

Material and methods:
Thirty-two Patients were divided into two groups;
Group A (control group): received flapped immediate implants combined with xeno graft.
Group B (Test group): received flapless immediate implants combined by xeno-graft. Evaluation include Presence of infection.Wound dehiscence. Implant exposure. Graft exposure or loss. Soft tissue dehiscence. Implant stability. Buccal bone height and lingual bone height of the extracted socket. Ridge width.

Results:
buccal bone height, flapless group showed a significant lower (0.09 mm) Change than flap (1.13 mm). Ridge width, at 2, 4, 6 mm, flapless group showed a significant lower Change than flap. Flapless group showed significant higher implant stability than flap.

Conclusion:
the flapless group has shown a lower reduction in height and width after placing immediate implants and filling the residual gap with an organic bovine bone. More ridge reduction was observed for the flapless group.
