简要总结
The goal of this clinical trial is to evaluate the bony changes around dental implants in non-vascularized iliac crest grafts and free vascularized fibular flap in mandibular reconstruction.
The main question it aims to answer are:
• evaluate the bony changes around dental implants and it's survival rate in both groups
详细描述
The current prospective study was conducted on 10 patients that were selected and admitted for early or delayed mandibular reconstructive surgery from the outpatient who were referred to the department of Oral and Maxillofacial Surgery Faculty of Dentisry, Ain Shams University in the period from January 2018 till June 2022.
The patients in this study were divided into two groups. First group endured non-vascularized iliac crest grafting with delayed implant insertion while the second group endured vascularized fibular flap with delayed implant insertion. Implant placement was done six months after performing reconstructive surgery.At the second stage surgery, all succeeded implants were loaded with fixed implant supported prothesis. Follow- up was done 1 week, 2 weeks, 4 weeks, 8 weeks and 12 weeks postoperatively.
Crestal bone stability was analyzed using CBCT radiographs along with the percentages of of the survived implants and ISQ values were measured using an ostell device.
