Abstract

Statement of problem

Consideration of the thickness of alveolar bone on both the palatal and labial sides and the inclination angle of teeth is important for immediate implant placement in the maxillary anterior region. However, comprehensive research exploring how sex and age influence the thickness of bone and tooth angle in the maxillary anterior region is lacking.

Purpose

The purpose of this clinical study was to investigate the effect of sex and age on the thickness of labial and palatal bone and on the tooth inclination angle of maxillary central and lateral incisors using cone beam computed tomography (CBCT) images in an Asian population.

Material and methods

The labial and palatal bone thickness and the inclination angle of maxillary central and lateral incisors were measured from the CBCT images of 149 participants aged between 20 and 65 years. The correlation between the angles of the maxillary central and lateral incisors and sex and age on the tooth angles and thicknesses of labial and palatal bone was determined statistically.

Results

A high correlation (R=0.73) was found between the angle of maxillary central and lateral incisors. Men had higher angles of the maxillary central and lateral incisors and thicker palatal bone at the middle and root of the teeth compared with women. In both sexes, the angle and palatal bone thickness of maxillary central incisors were significantly higher than those of maxillary lateral incisors. The angle of both maxillary central and lateral incisors decreased gradually with age, with a difference in angle of over 10 degrees.

Conclusions

The study revealed that women exhibited relatively thinner palatal bone compared with men. Additionally, participants aged between 40 and 65 years exhibited significantly thicker palatal bone compared with younger age groups, potentially providing a larger site for implant placement. Furthermore, tooth angle gradually decreases with age in the maxillary anterior region.

在上颌前牙区植入种植体时，考虑性别和年龄因素，对牙齿角度和周边骨厚度进行临床评估。

问题陈述：考虑腭侧和唇侧牙槽骨的厚度以及牙齿的倾斜角度对于上颌前牙区的即刻种植体植入非常重要。目的：本临床研究的目的是利用锥形束计算机断层扫描（CBCT）图像，在亚洲人群中调查性别和年龄对上颌中切牙和侧切牙唇侧和腭侧牙槽骨厚度以及牙齿倾斜角度的影响：从 149 名年龄在 20 岁至 65 岁之间的参与者的 CBCT 图像中测量了他们的唇和腭骨厚度以及上颌中切牙和侧切牙的倾斜角度。通过统计学方法确定了上颌中切牙和侧切牙的角度与性别和年龄在牙齿角度和唇腭骨厚度上的相关性：上颌中切牙和侧切牙的角度之间存在高度相关性（R=0.73）。与女性相比，男性上颌中切牙和侧切牙的角度更大，牙齿中部和根部的腭骨更厚。无论男女，上颌中切牙的角度和腭骨厚度都明显高于上颌侧切牙。随着年龄的增长，上颌中切牙和侧切牙的角度逐渐减小，角度差异超过 10 度：研究显示，女性的腭骨相对于男性较薄。此外，与年轻群体相比，40 至 65 岁的参与者腭骨明显较厚，这可能为种植体植入提供了更大的空间。此外，随着年龄的增长，上颌前牙区的牙齿角度会逐渐减小。
