ABSTRACT
Objective:
To compare the bone dimensional changes following tooth extraction alone with extraction plus ridge preservation ( using deproteinized boving bone mineral Bio-Oss? and bioresorbable collagen mambrane Bio-Gide?) in periodontal compromised extraction sockets .Methods:
Eighteen molars of sixteen subjects requiring tooth extraction because of periodontal destruction were enrolled in this study .The subjects were assigned to the control group ( extraction alone , EXT) or to the test group ( ridge-preservation procedure with Bio-Oss? and Bio-Gide?, RP) .Parallel periapical X-rays and cone-beam computed tomography ( CBCT ) scans were taken immediately after tooth extraction alone or plus ridge-preservation ( baseline ) and 6 months later .The changes of horizontal ridge width and vertical ridge height were assessed .Results:
At the central buccal aspect , the ridge height increased 2 .9 mm in RP group, and reduced 1.0 mm in EXT group.At the distal buccal aspect , the ridge height increased 1.45 mm in RP group, and reduced 1.45 mm in EXT group.The differences between the groups reached statistical significance (P0.05).Conclusion:
The ridge-preservation approach using Bio-Oss? in combination with Bio-Gide? can significantly increase vertical ridge height and horizontal ridge width after tooth extraction compared with extraction alone in periodontal compromised molars .
