“…A meta-analysis was not performed for this reason. Twenty-one studies 3,4,6,8,9,15,[18][19][20][22][23][24][25][26][28][29][30][31][32][33][34] were retrospective, five studies 7,11,12,16,17 were prospective, and four studies 5,10,21,27 were prospective and randomized. Six studies 10,18,[22][23][24]33 compared the results with a control group of the same age, and eight studies 4,6,10,12,22,[32][33][34] analyzed the long-term effects of RME.…”

“…1 The applied force causes widening and gradual opening of the midpalatal suture, compression of the periodontal ligament, bending of the alveolar processes, and dental tipping. 2,3 Although RME has been recognized as a safe and reliable orthopedic procedure that allows correction of the maxillary transverse deficiency in growing patients, some investigations [4][5][6][7][8][9][10] have focused on the unwanted consequences of heavy forces on sutures, periodontal alveolar bone, and dental structures identified as ''Adverse Effects'' (AEs). Moreover, other authors 11,12 have reported that RME with conventional appliances promotes the anterior and inferior displacement of the maxilla with a consequent posterior-inferior rotation of the mandible.…”

Objective: To assess the scientific evidence that rapid maxillary expansion (RME) causes Adverse Effects on the midpalatal suture, vertical dimension, dental and periodontal structures in growing subjects. Materials and Methods: Electronic databases were searched for articles dated through December 2011. The quality of the studies was ranked on a 13-point scale in which 1 was the low end of the scale and 13 was the high end. Results: Thirty relevant articles were identified. The amount of midpalatal suture opening ranged from 1.6 to 4.3 mm in the anterior region and from 1.2 to 4.4 mm in the posterior region. At the end of the active phase, RME resulted in slight inferior movement of the maxilla (SN-PNS +0.9 mm; SN-ANS +1.6 mm), increased tipping of anchored teeth from 3.4u to 9.2u and bending of the alveolar bone from 5.1u to 11.3u. In the long term, RME did not modify the facial growth patterns, and no significant changes on dentoalveolar structures were observed. Of the 30 studies, 2 were medium-high quality, 8 were medium quality, and 20 were low quality. Conclusions: RME always opened the midpalatal suture in growing subjects. The vertical changes were small and transitory. In the long-term evaluation, an uprighting of anchored teeth was observed and periodontal structures were not compromised.

“…Although many different RME appliances have been developed to minimize the dento-alveolar inclination (Memikoglu andİşeri, 1999 andBaşçiftçi andKaraman, 2002), occurrence of dento-alveolar tipping is unavoidable (Wertz, 1970 andBishara andStaley, 1978). Asanza et al (1997) and Ciambotti et al (2001) found less molar tipping in patients treated with a Hyrax expander according to their studies. This difference may owe to the different measurement techniques employed for the determination of inclination.…”

“…There have been some studies (24,25) suggesting that there was lower tipping in the posterior teeth after RME with acrylic bonded appliance and there have been some other studies (26,27) which found more tipping in RME groups than in slow expansion groups. In our study, after the active expansion period, U6R° value increased to 8.9° in SRME and 9.39° in RME groups.…”

Anah tar Ke li me ler Öz AbstractObjective: The purpose of this study was to compare the skeletal, dentoalveolar and periodontal effects that occurred after rapid maxillary expansion (RME) and semirapid maxillary expansion (SRME) with an acrylic splint bonded expansion appliance and also to compare the degree of root resorption in the supporting teeth during expansion. Materials and Methods:The sample of the study included 19 patients having maxillary constriction requiring bilateral upper premolar extraction. The semi-rapid group consisted of 10 patients and the rapid group consisted of 9 patients. Lateral and posteroanterior (PA) cephalometric radiographs were taken at the beginning of the treatment, at the end of expansion and after 3 months of retention period. Eleven patients underwent low-dose computed tomography (CT) at the beginning of treatment and at the end of retention period, after giving informed consent. The evaluation of root resorption was made using a scanning electron microscope from the extracted teeth. Results: Both lateral and PA radiographs showed similar changes between the groups. Posterior nasal cavity width, palatal maxillary width, the distance between palatinal roots and the distance between incisor roots showed significant increase in the CT measurements. Buccal bone thickness decreased and palatal bone thickness increased in all molar and premolar teeth examined. Root resorption was seen in both groups, but no significant differences were observed between the groups. Conclusion: Some differences were seen in short-time effects between SRME and RME but these differences were temporary and disappeared at the end of the retention period. The qualitative evaluation of the roots showed that the location and degree of the root resorption were similar between the groups.Amaç: Bu çalışmanın amacı, akrilik splintli bonded ekspansiyon apareyi ile yapılan yarı hızlı maksiller ekspansiyon (SRME) ve hızlı maksiller ekspansiyon (RME) ile meydana gelen iskeletsel, dentoalveolar ve periodontal etkileri; ayrıca tedavi sırasında destek dişlerde meydana gelen kök rezorpsiyonunun şiddetini karşılaştırmaktır.
