ObjectiveTo determine the relationship between buccal bone and soft tissue thickness at teeth in the premaxilla by means of non-invasive registration methods. Materials and MethodsBuccal bone thickness at central incisors, lateral incisors and canines was measured at five reference points (1-5mm from the top of the alveolar crest) on CB-CT scans of 21 patients. The corresponding buccal gingival thickness was measured by the use of an ultrasonic device. Spearman's correlation coefficient was calculated to assess the correlation between buccal bone and soft tissue thickness at each tooth type ResultsMean buccal bone thickness (SD) at central incisors, lateral incisors and canines was 1.07mm (0.34mm), 1.16mm (0.54mm) and 0.98mm (0.37mm), respectively. For central incisors, 68% of all sites had a thickness <1mm and 32% had a thickness between 1.0 and 2.0mm. At lateral incisors, 44% demonstrated buccal bone thickness between 0 and 1.0mm, 48% between 1.0 and 2.0mm and 8% 2mm. For canines, 57% of the sites were <1mm thick; 41% were between 1.0 and 2.0mm thick, and 2% demonstrated 2mm thickness. Mean gingival thickness (SD) at central incisors, lateral incisors and canines was 1.37mm (0.32mm), 1.33mm (0.32mm) and 1.08mm (0.25mm), respectively. The correlation between buccal bone and soft tissue thickness was moderately positive (=0.406; P<0.001 ConclusionsA thin buccal bone wall (<1mm) may be expected in over half of the central incisors and canines. The correlation between buccal bone and soft tissue thickness was moderately positive
