Abstract
Aim: The aim was to compare the value and efficiency of sticky bone in the augmentation of horizontal alveolar ridge deficiency when used with or without xenogeneic bone graft for esthetic endosseous implant placement. Methodology: A total of 12 sites that require bone grafting for implants placement for class IV ridge classification (2-4 mm residual alveolar width) were included in the study. 4 patients received horizontal augmentation using sticky bone prepared from 1:1 mixture of autogenous and xenograft bone covered by the PRF membrane.The other 4 patients received horizontal augmentation using sticky bone preparation of autogenous particulate bone covered by the PRF membrane. A modification of miniscrews for stabilization of the bone graft was introduced during the research course. CBCT scans were taken immediate postoperative and after 6 months to measure the horizontal bone gain in both groups. Results: Bone measured at 2, 5, and 10 mm from the alveolar crest. In control group, a mean width gain of 0.79±0.99 mm was observed immediately after surgery and a 0.37±1.39 mm mean width gain was detected 5 months post-surgery. A total width gain of 1.27±1.13 mm was measured from baseline to 5 months post-surgery. While in intervention group, a 0.14±0.84 mm mean width gain was observed at immediate post-operative period. However, a mean width reduction of 0.32±1.69 mm was measured 5 months post-surgery and total width reduction of 0.18±1.33 mm was measured from baseline to 5 months.There was no statistically significant difference in width mean changes between both treatment groups immediately post-operative (P=0.119) and after 5 months (P=0.330). While the control group yielded a higher total width gain from baseline to 5 months compared to the intervention group (P=0.017)
