Anthropometric evaluation of labial alveolar bone dimension of maxillary anterior teeth in Kuantan population: a conebeam computed tomography study
Introduction: Labial bone with adequate height and width is crucial for an implant to be successfully placed and ensure the stability of treatment outcome in the long term. The objective of this study was to employ cone-beam computed tomography (CBCT) assessment in evaluating the differences in la...

Summary: | Introduction: Labial bone with adequate height and width is crucial for an implant to be successfully placed and
ensure the stability of treatment outcome in the long term. The objective of this study was to employ cone-beam
computed tomography (CBCT) assessment in evaluating the differences in labial alveolar bone morphology among
the Kuantan population in Malaysia. Methods: A total of 60 images taken from Kulliyyah of Dentistry, International
Islamic University Malaysia, between 2009 and 2019 were analysed. The root diameter, labial and palatal plate
thickness, the labial bony curvature angle beneath the root apex, and the distance from the deepest point of labial
bony curvature to the root apex were all measured on each of the maxillary anterior teeth. Results: At 3 mm below
the cementoenamel junction, the mean (± standard deviation; SD) thickness of the labial plate for maxillary anterior
teeth was 1.45 ± 0.62 mm, 1.38 ± 0.50 mm, and 1.61 ± 0.66 mm for the lateral incisor, central incisor, and canine,
respectively. Below the root apex, the labial bony curvature angle was 233.63 ± 17.74 for the central incisor, 235.68
± 17.74 for the lateral incisor and 233.81 ± 11.09 for the canine. Discussion: The result revealed a favourable labial
plate in the Kuantan population when implant in the aesthetic zone is planned. Conclusion: Labial alveolar bone
thickness of the Kuantan population was thin within 1.5 mm while the palatal plate was thick. Overall, labial alveolar
bone was present within 3 mm below the cementoenamel junction. The labial bony curvature was highest and most
curved for the central incisor compared to the lateral incisor and canine. |
