Abstract
The aim of this study was to compare between osseointegration of immediate
implant placement in fresh dentoalveolar socket versus infected dentoalveolar
socket.The teeth extraction were done atrumatically as possible without
mucoperiosteal flap elevation, and without the use of any graft material.
Ten patients were participated in this study and they were free from any
systemic or local health conditions that can compromise implant success.They
received ten submerged TUT endosseous root form implants to replace their
missed single teeth.
The surgical procedures that applied in this study were performed under local
aneasthesia. The surgical procedure included atraumatic extraction, drilling
through the socket by subsequent drills to the selected depth and width that achieve
implant stability and maximum adaptation between the implant and socket wall.
Each patient was evaluated clinically and radiographically immediate postoperative,
6 weeks 12 weeks and 24 weeks. Clinical evaluation included pain,
tenderness, and infection, and swelling, soft tissue healing and implant exposure.
On the first day after surgery post operative minimal or no edema was observed,
and discomfort or mild pain were reported. All patients continued the follow up
periods without any signs of infection, gingivitis or Peri-implantitis. Three implant
from both group were observed with cover screw exposure at 12 week follow up.
After exclusion of one case in early stage of the study, which were replaced by
another case due to buccal plate perforation due to infection. On the other hand,
The radiographic evaluation revealed no peri-implant radiolucency around all
fixtures which indicated successful osseointegrated implants.
Summary and Conclusion
105
Radiographic evaluation was done in order to assess the bone density and
crestal bone loss. There was significant increase in the bone density in both groups
after 6th week till 24th week, however no significant statistical difference were
reported at 24 weeks. There was significant increase in the crestal bone loss in both
groups after 6th week till 24th week, while There was no significant difference in
the bone density and crestal bone loss between both groups through all the
evaluation periods.
