“…17,24,25 Leung et al 26 showed that alveolar bone height and thickness can be measured quantitatively with great accuracy, with more than 0.870 correlations. Sun et al 23 observed that decreasing the voxel size from 0.40 mm to 0.25 mm could improve the accuracy of alveolar bone linear measurement from the CBCT images. Molen 27 recommended that a voxel size less than 0.30 mm could provide better average spatial resolution for adequately visualizing alveolar bone.…”

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.

“…(SCHEI et al, 1959;SUOMI et al, 1971) Um dos critérios de inclusão foi a necessidade de o paciente ter sido submetido à cirurgia de enxerto ósseo alveolar secundário, por esta ser a cirurgia de escolha devido às inúmeras vantagens, dentre elas a de garantir suporte periodontal para a irrupção e preservação dos dentes adjacentes à fissura sem interferir no crescimento da maxila. Todas as cirurgias tiveram como área doadora a crista ilíaca, por ser uma área discreta, com maior quantidade de osso medular esponjoso (FREIHOFER, KUIJPERS-JAGTMAN, 1989;GOUDY et al, 2009;KOOLE,BOSKER, VAN DER DUSSEN, 1989;QUERESHY et al, 2012) , LANGDON, 1991;FEICHTINGER,MOSSBOCK, KARCHER, 2007;KAWAKAMI et al, 2003;LILJA et al, 2000;SILVA FILHO et al, 2000;SILVA FILHO et al, 1999;TAI,SUTHERLAND, MCFADDEN, 2000;TAN et al, 1996) GARIB et al, 2010c;HILGERS et al, 2005;HONDA et al, 2004;KOBAYASHI et al, 2004;LASCALA,PANELLA, MARQUES, 2004;MAH et al, 2011;MARMULLA et al, 2005;MILLER,KUO, CHOI, 2003;MISCH,ERICA, SARMENT, 2006;PINSKY et al, 2006;SUN et al, 2011;TIMOCK et al, 2011;TSIKLAKIS,SYRIOPOULOS, STAMATAKIS, 2004) As tomografias foram realizadas com um voxel de 0,25mm, para obtenção de maior resolução espacial, permitindo a visualização das tábuas ósseas alveolares.…”

AimTo compare the linear and angular measurements of the mandibular symphyseal region using lateral cephalometric (LC) and cone beam computed tomography (CBCT) images.Materials and MethodsOne hundred patients justifying both LC and CBCT exposures were included. Both lateral cephalometric and CBCT images of the patients were used for angular and linear measurements. Angular measurements included vestibular concavity and lingual and tooth inclination angles. Vestibular and lingual cortical bone and total bone thickness measurements were obtained for the comparison of linear measurements. Three radiologists performed the measurements on 200 images. Comparison of the measurements and the imaging methods were done using paired‐ and Wilcoxon t‐tests. Inter‐observer reliability was evaluated with the intra‐class correlation coefficient (ICC).ResultsA significant difference was observed between measurements of two imaging methods for tooth inclination and vestibular concavity angles; however, no difference was found between LC and CBCT measurements for lingual inclination angle (p > 0.05). Vestibular cortical bone and total bone thickness measurements showed a significant difference (p < 0.05), whereas no difference was obtained in lingual bone thickness measurements of two imaging methods (p > 0.05).ConclusionCBCT imaging is recommended in selected patients where recipient bone or bone augmentation site(s) reveal suspect in clinical examination and lateral cephalometric imaging may not reveal the true anatomic structure and relationships.
