Abstract
ABSTRACTIntroduction: The surgically assisted rapid maxillary expansion is a procedure that reduces the resistance of the sutures correcting the posterior crossbite in adults. Objective: The aim of this study was to evaluate the periodontal status of 17 adults submitted to this procedure. Methods: The clinical attachment level (CAL), gingival recession, attached gingiva and bleeding were evaluated in maxillary first premolars and molars, central and lateral incisors of right and left sides before surgery, 5 days and 6 months after. Means, standard deviation, medians, minimum and maximum values were compared among the evaluations using the Friedman and McNemar tests. Results: There was a statistically significant increase in CAL in the right central incisor, right and left premolars and right and left molars. There was a statistically significant increase in gingival recession in the right and left premolars and molars. The amount of attached gingiva significantly decreased in right premolars and right and left molars. There was increase in bleeding in most of the teeth. Conclusion: Results indicated that the surgically assisted rapid maxillary expansion might cause alterations in periodontal tissue.
Highlights
The surgically assisted rapid maxillary expansion is a procedure that reduces the resistance of the sutures correcting the posterior crossbite in adults
Due to the frequent use of the surgically assisted rapid maxillary expansion (SARME) in the correction of transverse skeletal discrepancies in adults and the scarce data in the literature regarding possible periodontal alterations caused by this procedure, the present study aimed to investigate the periodontal status of patients after appliance installation, at the fifth day and six months after surgery
STATISTICAL METHODS The measurements of clinical attachment level, gingival recession, bleeding, and attached gingiva were performed at three distinct times: after the appliance installation (T0), at the fifth day after surgery (T1) and 6 months after surgery (T2) for each tooth
Summary
The surgically assisted rapid maxillary expansion is a procedure that reduces the resistance of the sutures correcting the posterior crossbite in adults. AND LITERATURE REVIEW Rapid maxillary expansion (RME) is a procedure used in the treatment of young patients with maxillary atresia In adults, this procedure has high failure rates due to increased rigidity of the maxillary sutures, and it can cause dental inclinations, osseous dehiscence and gingival recession.[1,2,3,4] For this reason, the surgical separation of the midpalatal suture has to be performed. This procedure has high failure rates due to increased rigidity of the maxillary sutures, and it can cause dental inclinations, osseous dehiscence and gingival recession.[1,2,3,4] For this reason, the surgical separation of the midpalatal suture has to be performed This procedure named surgically assisted rapid maxillary expansion (SARME) is indicated[5,6,7] in adult patients to correct significant transversal maxillary atresia, posterior crossbite, failure of orthopedic expansion and reduction of buccal corridors of smile.[8,9]. More conservative techniques are described in the literature, without osteotomy of the midpalatal suture and of the pterygomaxillary suture.[6]
