Resorbable vs Non-resorbable Barriers with Immediate Implantation after Functional Loading under Overdenture

Abstract

Aim The aim was to evaluate the bone height and bone density of the peri-implant area with resorbable and non-resorbable barriers as guided tissue regeneration with immediate implants after functional loading under mandibular overdenture. Materials and methods Eight male patients (the age ranged between 45 and 60 years old), who had the upper jaw as fully edentulous and the lower jaw with only two remaining canines and indicated for extractions, were selected. Each patient received two immediate implants after extraction of remaining canines and were divided into two groups: Group I: The left side received non-resorbable barrier and group II: The right side received resorbable barrier. Radiographic evaluation was done for marginal bone height loss and bone density immediately after overdenture insertion and 6 months later. Results Mean marginal bone loss with non-resorbable barriers was 0.7 ± 0.16 mm and with resorbable barrier was 0.6 ± 0.1 mm, with nonsignificant difference between the two groups. There was significant increase in bone density with resorbable barrier after 6 months of functional loading, with significant difference between the two groups. Conclusion There was no difference in marginal bone height changes between resorbable and non-resorbable barriers with immediate implant under overdenture. However, after 6 months of functional loading, bone density increased with the use of resorbable barrier over non-resorbable barriers. Using of resorbable barrier with immediate implantation did not require second stage surgery for removing the barrier as with the non-resorbable one. How to cite this article Elkholy S, Elcharkawi H.
