“…11,18,19 Most studies showed that RME procedures reduce the amount of alveolar bone at different levels. 20,21 Garib et al 10 found a 3.8-mm decrease in the BABH of the first molar and observed that tooth-borne RME appliances decreased bone levels more than did tooth-tissue-borne appliances. To our knowledge, no studies have been published about the buccal alveolar bone effects of asymmetric RME.…”

Objective: To quantitatively evaluate the effects of asymmetric rapid maxillary expansion (ARME) on cortical bone thickness and buccal alveolar bone height (BABH), and to determine the formation of dehiscence and fenestration in the alveolar bone surrounding the posterior teeth, using conebeam computed tomography (CBCT). Materials and Methods: The CBCT records of 23 patients with true unilateral posterior skeletal crossbite (10 boys, 14.06 6 1.08 years old, and 13 girls, 13.64 6 1.32 years old) who had undergone ARME were selected from our clinic archives. The bonded acrylic ARME appliance, including an occlusal stopper, was used on all patients. CBCT records had been taken before ARME (T1) and after the 3-month retention period (T2). Axial slices of the CBCT images at 3 vertical levels were used to evaluate the buccal and palatal aspects of the canines, first and second premolars, and first molars. Paired samples and independent sample t-tests were used for statistical comparison. Results:The results suggest that buccal cortical bone thickness of the affected side was significantly more affected by the expansion than was the unaffected side (P , .05). ARME significantly reduced the BABH of the canines (P , .01) and the first and second premolars (P , .05) on the affected side. ARME also increased the incidence of dehiscence and fenestration on the affected side. Conclusions: ARME may quantitatively decrease buccal cortical bone thickness and height on the affected side.

“…35,56 While all studies on rapid palatal expansion treatment demonstrated both dental and alveolar tipping, none found detrimental effects (such as dehiscences or fenestrations) to the alveolar bone supporting the posterior teeth. [57][58][59][60][61][62][63] CBCT images are clear enough to measure alveolar bone thickness to an accuracy of 0.6 mm. 64,65 In fact, one recent study suggested that CBCT images with a voxel size of 0.4 mm actually overestimate alveolar bone loss following rapid palatal expansion.…”

Cone beam computed tomography use in orthodontics

Cone beam computed tomography (CBCT) is widely used by orthodontists to obtain three‐dimensional (3‐D) images of their patients. This is of value as malocclusion results from discrepancies in three planes of space. This review tracks the use of CBCT in orthodontics, from its validation as an accurate and reliable tool, to its use in diagnosing and treatment planning, and in assessing treatment outcomes in orthodontics.

“…[39]CBCT studies on SARPE showed that it has a significant clinical impact on the periodontium.It includes decrease in the buccal alveolar bone thickness( BABT) on most teeth ,increase in the palatal alveolar bone thickness , considerable decrease in the buccal alveolar crest level and decrease in the interproximal alveolar crest level on the mesial aspect of both central incisors. [2] CBCT studies to find immediate and postretention effects of RPE showed significant increase in transverse dimensions at the crown and apex levels of first molars.At the end of active phase of expansion the buccal bone plate thickness of the supporting teeth showed a significant decrease and after a retention period of 6 months there was recovery of both buccal and lingual plate thickness. [40]Banded and bonded hygienic expanders had similar effects on the buccal bone of the maxillary posterior teeth.…”

“…In skeletally immature patients, rapid orthopedic palatal expansion (RPE) is a common method of treatment. [2] Transverse separation of the maxillae through rapid palatal expansion also has the potential for increasing arch perimeter by unravelling crowding in the maxillary arch and helps in correction of disharmonies in thetransverse plane between maxillary and mandibular arches. This procedure which was used as a method of crossbite correction has now has its application for levelling the curve of Wilson, reducing the dark spaces in the buccal corridors and perhaps increase in airway patency [1,4] The increase in palatal width is the result of growth in the midpalatal suture, which itself undergoes a continual morphological change at the histological level, becomingsuccessively more complicated from birth to the cessation of development.…”
