Buccal bone graft with surgically assisted rapid maxillary expansion in young adults; A cone beam computerized tomographic comparative study

Abstract

Objectives: The aim of this study was to evaluate the dentoskeletal effect of buccal bone graft with buccal surgically assisted rapid maxillary expansion in young adults using cone beam computed tomography. Methods: The current randomized clinical study was conducted on a total sample of 21 orthodontic patients. The sample with mean age 20 Y. CBCTs were taken before and after orthodontic expansion. The patients were divided in to three groups, group I: consisted 7 patients treated with Hyrax expander, in conjunction with selected Buccopalatal corticotomy, group II: consisted 7 patients treated with Hyrax expander, in conjunction with selected Buccal corticotomy only, group III consisted 7 patients treated with Hyrax expander, in conjunction with selected Buccal corticotomy only, followed by immediately placement of bone graft directly over the decorticated plate. Results: The results showed high significant increase in buccal bone thickness in the group III. On the other hand, there was a significant decrease increase in buccal bone thickness in groups I&II. Conclusion: The buccal bone graft with surgically assisted RME in young adult leads to increase in buccal bone thickness than the other technique without bone graft. The other two techniques without bone graft showed significant reduction in buccal bone thickness.
