Abstract

Introduction: The maxillary anterior region is becoming a major concern due to its aesthetic relevance. The buccal bone thickness is important for implant placement, orthodontic treatment and restorative treatment. Objective: To assess the thickness of alveolar bone in the maxillary central incisor using cone beam computed tomography (CBCT). Methods: A cross-sectional observational study was conducted at Department of Dental Surgery, Bir Hospital where CBCT of 53 samples from July 2019 till December 2019, the archived CBCT images was assessed retrospectively. The thickness of the labial bone in a direction perpendicular to the outer surface of the tooth root was measured at a distance of 2 mm from the cementoenamel junction (CEJ). The measurement was taken thrice and the mean measurement was considered. Results: The labial alveolar bone thickness in maxillary central incisor was found to be 0.55±0.27 mm at a distance of 2 mm from the CEJ. Only 2 (3.8%) of the samples had an alveolar thickness of >1 mm. No statistically significant difference was found with respect to gender and age. Conclusion: The average thickness of the labial alveolar bone in maxillary central incisor using cone beam computed tomography was found to be thin.

锥形束计算机断层扫描评价上颌中切牙唇槽骨厚度
简介:上颌前区正成为一个主要的关注,由于其美学的相关性。颊骨厚度对种植体植入、正畸治疗和修复治疗具有重要意义。目的:应用锥形束计算机断层扫描(CBCT)评价上颌中切牙牙槽骨厚度。方法:在Bir医院口腔外科进行横断面观察研究,对2019年7月至2019年12月53例样本的CBCT进行回顾性评估。在距牙髓-牙釉质交界处(CEJ) 2 mm处测量垂直于牙根外表面方向的唇骨厚度。测量了三次,并考虑了平均值测量。结果:上颌中切牙唇槽骨厚度为0.55±0.27 mm。只有2个(3.8%)样本的肺泡厚度为bb0.1 mm。性别和年龄差异无统计学意义。结论:锥形束ct显示上颌中切牙唇槽骨平均厚度偏薄。
