Dental implants are a known treatment today. It is necessary to have at least 2 mm of bone around the implant, especially in the buccal aspect of the anterior maxilla (esthetic zone). Some systemic conditions, such as menopause, can affect the body's bone mass as well as the alveolar bone. Considering that few studies have been carried out on the effect of menopause on the thickness and topography of alveolar bone, we decided to investigate the effect of menopause on buccal alveolar bone thickness in the anterior maxillary teeth in menopausal women. MATERIAL AND METHODS: In this descriptive-analytical cross-sectional study, two subgroups of menopausal women and nonmenopausal women were considered. Data were extracted from 30 patients referred to a private radiology center in Mashhad for CBCT imaging. In addition, the buccal bone thickness in the crest and middle areas of the anterior maxillary teeth was measured and the difference between the two groups was investigated. The buccal bone thickness of the aesthetic area was evaluated with CBCT Planmeca ProMax 3D Max (Planmeca) by Planmeca Romexis 5.3.4 software, with 200 μm Voxel size and Fov 90 × 60 mm.
In this study, 30 women with a mean age of 49.75 ± 3.65 years in the nonmenopausal and menopausal groups were examined. It was found that the mean buccal bone thickness of the anterior maxilla in the nonmenopausal group (0.65 ± 0.25 mm) was higher than in the menopausal group (0.56 ± 0.20 mm), but the difference was not statistically significant (p = .2999). Only in the crestal bone of the right canine, the average bone thickness in nonmenopausal group (0.77 ± 0.33 mm) was significantly higher than the menopausal group (0.49 ± 0.22 mm) (p = .011).
Owing to changes in the volume and thickness of alveolar bone in menopausal women, the thickness of the buccal bone in the aesthetic area decreases, but this is not statistically significant.
种植牙是目前已知的一种治疗方法。种植体周围至少需要 2mm 的骨组织，尤其是在上颌前牙的颊侧（美学区）。一些全身性疾病，如绝经，会影响身体的骨量和牙槽骨。考虑到关于绝经对牙槽骨厚度和地形影响的研究较少，我们决定研究绝经对绝经后女性上颌前牙颊侧牙槽骨厚度的影响。
在这项描述性分析性的横断面研究中，我们考虑了两组绝经和非绝经的女性。数据是从 30 名因 CBCT 成像而被转诊到马什哈德一家私人放射科中心的患者中提取出来的。此外，还测量了上颌前牙牙槽嵴和中部的颊侧骨厚度，并研究了两组之间的差异。使用 Planmeca Romexis 5.3.4 软件，通过 Planmeca ProMax 3D Max（Planmeca）对颊侧骨厚度进行评估，体素大小为 200μm，视野为 90×60mm。
在这项研究中，我们检查了 30 名年龄平均为 49.75±3.65 岁的女性，其中非绝经组（0.65±0.25mm）的上颌前牙颊侧平均骨厚度高于绝经组（0.56±0.20mm），但差异无统计学意义（p=0.2999）。只有在右侧犬牙的牙槽嵴顶，非绝经组（0.77±0.33mm）的平均骨厚度明显高于绝经组（0.49±0.22mm）（p=0.011）。
由于绝经后女性牙槽骨体积和厚度的变化，颊侧骨的厚度在美学区减少，但这没有统计学意义。
