“…Some limitations in accuracy have been reported for 0.3-mm voxel CBCT image evaluations, although they allow for precise measurements. [27][28][29] Alveolar bone with a thickness less than 0.3 mm may wrongly be diagnosed as ABD 28 and still be overestimated in a false-positive result in very thin bony plate regions. 28 Peterson et al 30 also reported an increase in the prevalence of ABD when measured using CBCTs as compared with clinical measurements.…”

Objectives The objectives were to evaluate and compare the presence of bone dehiscence before and after orthognathic surgery. Materials and Methods In this retrospective study, 90 cone-beam computed tomography (CBCT) scans from 45 patients were evaluated. Class II (n = 23) and Class III (n = 22) orthodontic patients who were being prepared for orthognathic surgery were measured. CBCT scans were obtained about 30 days prior to (T0) and 6 months after (T1) double jaw orthognathic surgery. The distance between the cemento-enamel junction (CEJ) and the alveolar bone crest was assessed at the buccal and lingual surfaces of all teeth, on both sides and arches, except for the second premolars and the second and third molars. A total of 1332 sites were measured for Class II (644) and Class III (688) patients. The software used was OsiriX (version 3.3 32-bit). Data were compared with Wilcoxon and McNemar tests at the 5% level. Results Bone dehiscence before surgery was present in 26% and 15% of the Class II and III groups, respectively. The presence of dehiscence increased to 31% in the Class II and 20% in the Class III patients after surgery (P < .05). Conclusions The prevalence of dehiscence increased slightly in Class II and Class III surgical-orthodontic patients after orthognathic surgery. Temporary vascular supply reduction and oral hygiene difficulties may explain these results; however, more studies are needed.

“…The thickness of the anterior alveolar bone has been investigated using CBCT (Chen et al, 2010;Menezes et al, 2010;Nowzari et al, 2012), yet few studies have assessed the height and inclination of alveolar bone, which might be the result of difficulty in selecting reference lines on 2D sections that generated from 3D CBCT scans. The lower mandibular line (LML) defined as the bisecting line of the right and left tangent lines to the lower border of mandibular angles and the mandibular symphysis (Downs, 1948;Yamada et al, 2007), and another line passing through the point menton and tangent to the most superior point in inferior border of the mandibular body (Yu et al, 2009), have been used to assess the inclination of the lower incisors and the overlying alveolar bone.…”

To propose a method of establishing the reference mandibular plane (MP), which could be reestablished according to the coordinates of the reference points, and then facilitate the assessment of anterior alveolar morphology using cone beam computed tomography (CBCT), sixty patients with bimaxillary protrusion were randomly selected and CBCT scans were taken. The CBCT scans were transferred to Materialism's interactive medical image control system 10.01 (MIMICS 10.01), and three dimensional models of the entire jaws were constructed. Reference points determining the reference MP were positioned in the coronal, axial, sagittal windows, and the points were exactly located by recording their coordinates in the interfaces of software. The reference MP provided high intra-observer reliability (Pearson's r 0.992 to 0.999), and inter-observer reliability (intra-class correlation coefficients (ICCs) 0.996 to 0.999).

“…A tomografia computadorizada por feixe cônico foi à ferramenta utilizada para realização desta pesquisa. Este exame permite avaliar as tábuas ósseas com nitidez expondo o paciente a menor dose de radiação que um exame obtido por tomografia multislice (Kobayashi et al, 2004;Loubele et al, 2008 Fuhrman, 1996;Tsunori et al, 1998;Nakajima et al, 2005;Mol;Balasundaram, 2008;Loubele et al, 2008;Garib et al, 2010;Lund et al, 2010;Menezes et al, 2010). Os softwares disponíveis para avaliar imagens geradas por tomografias computadorizadas oferecem ferramentas que permitem ajuste de brilho, contraste e ampliação das imagens visando o aumento de nitidez das mesmas (Fuhrman, 1996;Tsunori et al, 1998;Kobayashi et al, 2004;Loubele et al, 2008;Mol;Balasundaram, 2008;Lund et al, 2010).…”

Sei que estou em suas orações e tenho certeza de que essa energia me fortalece. Aos meus primos, Toninho e Cacá, pelo carinho e companhia. Sempre os considerei irmãos e a nossa estada em São Paulo fortaleceu esses laços. As minhas cunhadas Luciana Alves e Renata Nidalchichi pelo carinho que dedicam a mim e minha família. AGRADECIMENTO ESPECIAL Ao meu orientador, Prof. Dr. José Rino Neto, pela oportunidade de realizar o sonho de aprimorar o meu aprendizado nesta instituição. Serei eternamente grata por ter me recebido com respeito, atenção, dedicação, nunca poupando esforços para obter o melhor resultado em todos os projetos. Esteve disposto na tarefa de orientação, antevendo os momentos de dificuldade e dando incentivo. Obrigada por conduzir meus trabalhos de forma rigorosa incentivando-me a buscar a verdade com persistência e honestidade.
