“…Garib et al [11] concluded that minimal buccal tipping of the molars occurs with rapid expansion and more buccal tipping is seen with slow expansion. Their study however was conducted on non cleft patients.…”

Background: Management of patients with cleft lip and palate (CLP) includes orthodontic treatment prior to bone grafting. Palatal expansion is done using slow or rapid palatal expansions (RPE). Controversy still exists regarding choice of expansion appliances used. This study was conducted to find out whether the Quad helix appliance represents a reasonable alternative to using conventional rapid maxillary expansion appliance among cleft lip and palate patients. Methods: Twenty cleft lip and palate patients had orthodontic study models taken prior to expansion and at the end of expansion. There pre and post treatment study models were analyzed for changes in intermolar width, molar tipping and molar rotation. Result: The difference in molar tipping, increase in intercanine and molar width between slow palatal expansion (SPE) and rapid palatal expansion (RPE) group was not statistically significant. A difference between the two groups was found in the ability to rotate molars. Conclusion: The clinical findings suggest that maxillary expansion using the Quad helix appliance represents a reasonable alternative to using conventional rapid maxillary expansion appliances among cleft patients.

“…[9][10][11][12] Since the maxillary bones contribute significantly to nasal cavityÕs anatomical structure, the effects of RME are not just limited to the maxilla but extend to the surrounding nasal structures. [13][14][15][16] Conventional tomography has been used to evaluate volume changes in the nasal cavity after RME. 15,17 These authors reported that the internal area and volume increased significantly throughout the nasal cavity.…”

“…Several studies have exposed the effects of the RME in the nasal cavity (FARRONATO et al, 2008;GARIB et al, 2005;IWASAKI et al, 2014). Additionally, this study performed measurements of nasal cavity in stages T1 and T2 of treatment.…”

“…Several studies have addressed the dentoskeletal effects of these expander appliances (AKYALCIN et al, 2013;ASANZA et al, 1997;BAYSAL et al, 2013;FARRONATO et al, 2008;GARIB et al, 2005;GARRETT et al, 2008;IWASAKI et al, 2014;LAGRAVÈRE et al, 2010;REED et al, 1999;RODRIGUES et al, 2012;SARVER;JOHNSTON, 1989), however, the comparison between them still remains controversial, especially regarding to the vertical effects. Some authors concluded that the bonded expander increases the transverse dimension of the maxilla, but limits or even eliminates changes in vertical dimension (ASANZA et al, 1997;SARVER;JOHNSTON, 1989).…”

“…However, these methods are not appropriate for examining the changes during and after RME therapy because they are based on a two-dimensional representation of a three-dimensional object (AKYALCIN et al, 2013). Conventional radiographs can cause an overlap of the images, which compromises the diagnostic accuracy (GARIB et al, 2005). With the advent of the cone-beam computed tomography (CBCT), the clinician is enabled to acquire images in any plane without overlapping structures, and allowed to evaluate skeletal and dental changes quantitatively and three-dimensionally with minimal distortion (AKYALCIN et al, 2013;BAYSAL et al, 2013).…”

Cone-beam computed tomography evaluation of dentoskeletal effects produced by the bonded expander and hyrax: a pilot study

et al. 2016

ABSTRACT:The dentoskeletal effects produced by the bonded expander, principally the vertical ones, are controversial in the literature when compared with the effects produced by the hyrax, and have also been scarcely studied by means of cone-beam computed tomography (CBCT). This study aimed to evaluate the horizontal and vertical dentoskeletal effects produced by the bonded expander and by the hyrax using CBCT. The study sample consisted of ten patients, divided equally into two groups according to facial and cephalometric features: group 1, vertical facial growth pattern (two males, three females; mean age, 7.7 years) and group 2, normal facial growth pattern (three males, two females; mean age, 8.3 years), treated by bonded expander and hyrax, respectively. The patients were subjected to a CBCT scan before expansion and another scan four months after the end of the activations, when the expander was removed. Within each group and between the groups the horizontal and vertical effects were assessed using Student's t-test. The sample size was predetermined, and 5 patients were needed in each group to detect the differences at P < 0.05 with 90% power. Among the horizontal changes assessed, the nasal floor width (P = 0.03) and the greater internal width in the posterior region (P = 0.00) showed a statistically significant increase only for group 1, and the mandibular molar verticality showed a statistically significant increase only for group 2. The vertical changes showed no statistical differences within groups (P > 0.05). Comparing the two groups there were no statistical differences for any assessed change (P > 0.05). Considering there were no differences of the effects between the appliances, the bonded expander produced no greater vertical control compared to the hyrax. Nevertheless, further study is recommended in a larger sample size using CBCT.
