“…This type of malocclusion may be corrected in different manners, including slow expansion, [1][2][3] rapid expansion [4][5][6] and surgically assisted expansion. 7,8 Most rapid maxillary expansion treatments employ fixed tooth-tissue-borne and tooth-borne expanders. Rapid maxillary expansion is characterized by a widening of the midpalatal suture produced by forcing a lateral shift of the two horizontal processes of the maxilla.…”

Rapid palatal expansion: a comparison of two appliancesAbstract: This study analyzed occlusal radiographs to compare the transverse changes produced in patients treated with rapid maxillary expansion using two types of appliances. The sample consisted of 31 children aged 7 to 10.6 years, of both genders, with posterior cross-bite. Fifteen children were treated with a tooth-borne expander and 16 were treated with a tooth-tissue-borne expander. Occlusal radiographs obtained at treatment onset and at the end of the retention period were digitized. The following variables were measured: intermolar distance (IMD), interapical distance (IApD), interbase distance (IBaD) and interarm distance (IArD). The results revealed increases in all measurements in both groups after rapid maxillary expansion. Comparison between groups revealed that the increases were greater in patients treated with the tooth-borne expander, except for the IArD measurement, which presented the same increase in both groups. Even though the IMD measurements differed between expanders, they were proportional to the activation of the appliances (IBaD). The increase in the IApD measurement was proportionally greater in the group treated with the tooth-borne expander (0.7:1.0) than in that treated with the tooth-tissue-borne expander (0.4:1.0). It was concluded that both appliances had similar effects, although the tooth-tissue-borne expander produced a lesser opening at the apical region of the incisors.

“…Wertz and Haas have suggested that the vertical increase which was seen after RME was not permanent (3,21). In our study, a downward and backward movement of the mandible was observed in both groups, but there were no significant differences between the groups.…”

“…In the literature, some studies suggested that A point moves forward and downward with RME (3,(8)(9)(10)(11)(12)(13) but controversial views are also present (14)(15)(16)(17)(18). In the present study, some increases in SNA angle and the distance of the A point to the vertical reference plane (VR A) were measured in both groups, but these results showed no statistical significance.…”

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.

“…1,2 To date, the decision of whether to use surgically assisted RME (SARME) has been an age-based one, although no reliable correlation between chronological age and changes in the midpalatal suture in skeletally mature patients exists. 3 Since SARME results in a higher morbidity than conventional RME, 4,5 finding ways to determine if and to what extend the expansion of the maxillary complex will need surgical assistance or not is important to reducing the potential risks for the patient. 6 A decrease in the midpalatal suture width, which can be age and functional related, [7][8][9] is a potential prognostic factor for an increase of the resistance against conventional RME.…”

Objective: To conduct a pilot study to investigate the potentiality to determine the midpalatal sutural width radiographically with a flat-panel volume computed tomography (fpVCT) in a porcine model. Materials and Methods: Bone samples from the midpalatal suture of five young (16 weeks) and five old (200 weeks) sus scrofa domestica were gathered. The midpalatal suture width was measured via fpVCT and compared to respective histological preparations. Results with P , .05 were considered significant.
