Are Bondable Buttons a Better Option than Intermaxillary Fixation Screws for Achieving Maxillomandibular Fixation? A Prospective Randomized Clinical Study.

AIM: The aim of this study was to identify a better option in achieving maxillomandibular fixation (MMF) comparing bondable buttons and Maxillomandibular Fixation screws in achieving Maxillomandibular Fixation. PATIENTS AND METHODS: In this randomized clinical trial, study sample was derived from the population of patients who reported with minimally displaced mandibular fractures and who required Maxillomandibular Fixation. The patients were divided into two groups. In Group I (n = 20), Maxillomandibular Fixation was done with Maxillomandibular Fixation screws; on the other hand, in Group II (n = 20), bondable buttons were used. In both the groups the patients were analyzed for the time duration required in minutes for securing and removal of Maxillomandibular Fixation, plaque accumulation and postoperative stability. Plaque accumulation was evaluated using TURESKY-GILMORE-GLICKMAN modification of the Quigley-Hein plaque index. The complications encountered during and after the surgery were also analyzed.
RESULTS: The plaque accumulation and time required for placement and removal in group I were more as compared to group II. In Group I, there were more complications as compared to Group II such as tooth root damage, screw loosening, screw breakage and infection.
CONCLUSION: Bondable buttons are a better choice for achieving Maxillomandibular Fixation in comparison with Maxillomandibular Fixation screws for the treatment of minimally displaced mandibular fractures. Further studies with a bigger sample size must be carried out. © The Association of Oral and Maxillofacial Surgeons of India 2019.
