Background:The aim of this study was to evaluate the prognosis of minimal invasive horizontal alveolar ridge augmentation using small incision and subperiosteal tunneling technique.Methods: This study was conducted on 10 partially edentulous patients with horizontal alveolar bone deficiency in 12 areas that need horizontal alveolar ridge augmentation for future implant placement. Cone beam computer tomography was done for sites that need implant placement preoperatively. Xenogeneic bone was used for grafting deficient horizontal alveolar ridge sites using the flap technique in 6 areas and using the subperiosteal tunneling technique in another 6 areas for future implant placement. Cone beam computer tomography was done for grafted sites immediately postoperative and 6 months postoperative.Results: This study was conducted on 10 patients and included 12 implant sites. No complications related to bone grafting were found and there was an adequate clinical prognosis.Regarding the difference from pre-operatively to 6 months post-operatively, a slightly higher increase in ridge width was recorded in subperiosteal tunnel group (1.48±0.99) in comparison to flap group (0.91±0.94), with no statistically significant difference (p=0.086). Conclusions:The bone graft material retained within a pouch formed using small incision and subperiosteal tunneling technique resulted in additional increase within the width of the alveolar ridge than the flap technique.
Purpose: To compare success rate as well as difference of marginal bone loss around immediately placed non-functionally loaded implants in osteoporotic patients versus non-osteoporotic patients. Material & Methods: The present study was conducted on 12 patients, six of them were osteoporotic and the other six were normal healthy patients. Both groups underwent immediate post extraction implantation, with a total of 16 implants. Each patient was a candidate for single tooth replacement in the mandibular arch at the premolar area. CBCT was performed at the intervals of immediately after implant installation and 6 months postoperatively. This is to determine radiographic bone loss from initial surgery. Periotest was used to determine the implant mobility at the intervals of immediately after implant installation and 6 months postoperatively. Results: The marginal bone level (flushed implant-bone crest to implant apex) baseline records at time of implant placement was used for all cases as a reference. And then, measurements were taken again after six months to detect the change in the marginal bone level for both groups. After 6 months, the mean marginal bone loss of the osteoporotic group was slightly higher than the normal group but yet not of significant difference. There was no statistically significant bone loss difference between the two groups either in coronal or sagittal sections.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
