ABSTRACT:-
Objective: The objective of this study is to evaluate the crestal bone loss and survivability of dental implants in non-vascularized iliac crest grafts and free vascularized fibular flap in mandibular reconstruction. Materials and Methods: This study included eighteen patients which were divided into two groups. The first group (n=9) underwent non-vascularized iliac crest graft while the second group (n=9) underwent vascularized free fibular flap with delayed implant insertion in both groups. A total of 48 dental implants were placed and after 3 months, a second-stage surgery for implant loading with the planned prosthesis was performed. All succeeded implants were loaded with fixed implant supported prothesis. Radiographic assessment of crestal bone loss was recorded along with the percentages of the survived implants and statistically analyzed. The data was explored for normality using Shapiro-Wilk tests and were analyzed with independent t-test and Fisher’s exact test with a significance level of 0.05. Results: Crestal bone loss was significantly higher in the iliac graft group than in fibular graft group. Regarding the survivability results, 25 implants placed in the vascularized fibular graft group were successful in function. While for non vascularized iliac graft group 18 implants were successful. However, there was no significant difference between both groups. Conclusions: The crestal bone loss around the dental implants placed in vascularized free fibular grafts were less compared to those placed in non-vascularized iliac crest grafts. The survivability of the dental implants placed in both grafts were comparable.
