Summary
Ridge preservation procedures using bioactive glass maintained 77% of alveolar width. Computed tomography (CT) revealed less width reduction than vertical bone loss after 3 months.
Area of Science:
- Dental implantology
- Bone regeneration
- Periodontal surgery
Background:
- Alveolar ridge defects often necessitate bone augmentation before dental implant placement.
- Ridge preservation procedures (RPP) aim to minimize bone resorption after tooth extraction.
- Bioactive materials are utilized to enhance bone healing and preservation.
Purpose of the Study:
- To three-dimensionally evaluate bone changes following ridge preservation procedures (RPP) using computed tomography (CT).
- To quantify horizontal and vertical bone dimensions at alveolar sites treated with RPP.
Main Methods:
- Subjects requiring implant therapy underwent tooth extraction and RPP with bioactive glass.
- Computed tomography (CT) scans were obtained within 1 week and 3 months post-surgery.
- Superimposed CT scans allowed for horizontal and vertical radiographic measurements of bone changes.
Main Results:
- RPP preserved approximately 77% of original alveolar width, with a mean width loss of 1.8 ± 1.1 mm.
- Vertical bone loss averaged 2.7 ± 1.1 mm on the buccal aspect and 1.9 ± 1.2 mm on the lingual aspect.
- Significant differences in bone dimensional changes were observed between width and vertical measurements.
Conclusions:
- CT imaging effectively assessed bone changes after RPP.
- Ridge preservation procedures with bioactive glass demonstrated favorable bone maintenance at 3 months.
- Bone width was better preserved compared to vertical bone dimensions of the alveolar walls.
