Abstract

Introduction: Present study assessed the incidence of bond failures of orthodontic attachments during various orthognathic surgeries.
Materials and Methods: Treatment records of 100 patients undergone ortho-surgical rectification of skeletal malocclusion were divided into four groups: Maxillary Advancement (Max A), Maxillary Superior Repositioning (Max SR), Mandibular Advancement (Mand A), and Mandibular Setback (Mand S) surgery groups (25 patients, 200 molar tubes and 500 brackets in each group). The bond failure numbers for molar tubes and brackets during the surgical procedure were recorded. Values obtained from groups were added to attain the total number of bond failures during maxillary surgery and mandibular surgery.
Results: The incidence of bond failures did not differ significantly between Max A & Max SR groups and Mand A & Mand S groups (P-value>0.05). The incidence was higher in maxillary compared to mandibular surgery group (P-value<0>0.05).
Conclusions: The overall incidence of intra-operative bond failures reported was 4.75%. The debonding of molar tubes was more frequent (7.3%) than brackets (3.7%), with more incidence during maxillary surgery (5.57%) as compared to mandibular surgery (3.92%). Among the various orthognathic surgical procedures studied, the maximum bond failures were noted for maxillary superior repositioning (5.85%) and the least for mandibular advancement surgery (3.6%).
