Summary
Socket preservation with buccal overbuilding did not prevent bone loss after tooth extraction. While one technique showed less vertical bone loss, neither method fully compensated for ridge alterations.
Area of Science:
- Dental implantology
- Periodontology
- Oral surgery
Background:
- Tooth extraction often leads to significant ridge alterations.
- Socket preservation techniques aim to minimize these changes.
- Buccal overbuilding is explored as an adjunct to socket preservation.
Purpose of the Study:
- To histometrically evaluate ridge alterations after socket preservation alone.
- To assess socket preservation with additional buccal overbuilding.
- To compare different socket preservation and augmentation techniques.
Main Methods:
- Four treatment groups were established in beagle dogs.
- Treatments included socket filling with BioOss Collagen and various grafting techniques.
- Histometric analysis evaluated vertical and horizontal bone dimensions.
Main Results:
- All groups experienced horizontal and vertical bone loss.
- Socket preservation with combined free gingival/connective tissue graft (Tx 4) showed significantly less vertical buccal bone loss.
- No significant differences in horizontal bone dimensions were observed.
Conclusions:
- Buccal overbuilding combined with socket preservation may not fully counteract post-extraction ridge alterations.
- Further research is needed to optimize techniques for ridge preservation.
