For orthodontists, the position of the incisors is a key factor in setting treatment goals. Achieving maximum stability requires that they be positioned in the medullary portion of the alveolar bone, balanced with the lingual and labial musculature. Incorrect orthodontic movements can result in root resorption, dehiscences, or even fenestrations.
A systematic review of the bibliography was conducted in accordance with PRISMA recommendations. Searches were made in PubMed, Scopus, and Cochrane Library databases, using the same search terms in each, with no limitation on publication data, up to July 1st, 2024. The review accepted articles in any language. Randomized controlled trials, case-control studies, and cohort studies were included, both retrospective and prospective. Systematic reviews, meta-analyses, case reports, case series, literature reviews, and editorials were excluded. The quality of the articles was determined according to the CONSORT criteria.
The initial database search identified 167 articles: 89 in PubMed, 74 in Scopus, and 4 in the Cochrane Library. Of these, 75 were duplicates, leaving 92. After applying the inclusion criteria, a total of 8 articles were included in this systematic review.
This systematic review highlights the significant relationship between alveolar bone thickness and incisor inclination as assessed by CBCT. The bone thickness varies regionally, with the maxilla generally having thicker palatal bone and the mandible having thinner labial bone. CBCT is indispensable for evaluating cases involving severe skeletal discrepancies, preexisting bone defects, or planned movements beyond the alveolar limits, while traditional methods may suffice for less complex cases. Standardizing methodologies and conducting longitudinal studies with diverse populations are crucial for improving clinical guidelines and ensuring safe, effective treatment planning.
对于正畸医生而言，门牙的位置是设定治疗目标的关键因素。要实现最大程度的稳定性，需将门牙置于牙槽骨的髓质部分，并与舌侧和唇侧肌肉组织保持平衡。不正确的正畸移动可能导致牙根吸收、骨裂，甚至骨开窗。
按照PRISMA建议对文献进行系统综述。在PubMed、Scopus和Cochrane图书馆数据库中进行检索，每个数据库使用相同的检索词，对出版数据无限制，截至2024年7月1日。该综述接受任何语言的文章。纳入随机对照试验、病例对照研究和队列研究，包括回顾性和前瞻性研究。排除系统综述、荟萃分析、病例报告、病例系列、文献综述和社论。根据CONSORT标准确定文章质量。
初步数据库检索识别出167篇文章：PubMed中有89篇，Scopus中有74篇，Cochrane图书馆中有4篇。其中75篇为重复文章，剩余92篇。应用纳入标准后，本系统综述共纳入8篇文章。
本系统综述强调了CBCT评估的牙槽骨厚度与门牙倾斜度之间的显著关系。骨厚度存在区域差异，上颌腭侧骨通常较厚，下颌唇侧骨较薄。CBCT对于评估涉及严重骨骼差异、既往骨缺损或计划超出牙槽界限的移动的病例不可或缺，而传统方法可能足以处理不太复杂的病例。规范方法并对不同人群进行纵向研究对于改进临床指南和确保安全、有效的治疗计划至关重要。
