The aim of our study was to investigate vertical dentoalveolar compensation in untreated patients, in search of an association between vertical facial pattern and alveolar heights. This study involved the participation of 127 untreated Moroccan adults from the patient population of the ODF (Dentofacial Orthopedics) Department at the Center for Dental Treatment and Consultation (CCTD) in Rabat. Full adult dentition was the only criterion for inclusion. Patients with major syndromes and patients with facial clefts were excluded from the study. For the purposes of this analysis, we used profile teleradiography to measure vertical and sagittal skeletal variables as well as vertical dentoalveolar variables in the anterior and posterior maxillary and mandibular regions. We also measured the incisor axes. Analyses and statistical tests were performed with SPSS(®) statistics software (version 9.5 for Windows). Results indicate that: (i) upper posterior alveolar height (UPAH) does not correlate with skeletal variables of facial divergence, but correlates strongly with anterior facial height (AFH) and moderately with posterior facial height (PFH); (ii) lower anterior alveolar height (LAAH) correlates negatively with facial height index (FHI), positively with the FMA and AFH, but does not correlate with PFH; (iii) lower posterior alveolar height (LPAH) does not correlate with skeletal variables of facial divergence; (iv) upper anterior alveolar height (UAAH) changes inversely with FHI, correlates positively with the FMA and does not correlate with PFH.
我们研究的目的是调查未经治疗的患者的垂直牙牙槽代偿情况，以寻找垂直面部形态与牙槽高度之间的关联。本研究纳入了来自拉巴特牙科治疗与咨询中心（CCTD）牙颌面正畸（ODF）科患者群体的127名未经治疗的摩洛哥成年人。纳入的唯一标准是拥有完整的恒牙列。患有主要综合征的患者和面部裂患者被排除在研究之外。为了进行本分析，我们使用侧位远距X线摄影测量垂直和矢状骨骼变量以及上颌和下颌前后部区域的垂直牙牙槽变量。我们还测量了切牙轴。使用SPSS（®）统计软件（Windows版9.5）进行分析和统计测试。结果表明：（i）上颌后牙槽高度（UPAH）与面部发散的骨骼变量无关，但与前面部高度（AFH）密切相关，与后面部高度（PFH）中度相关；（ii）下颌前牙槽高度（LAAH）与面部高度指数（FHI）呈负相关，与FMA和AFH呈正相关，但与PFH无关；（iii）下颌后牙槽高度（LPAH）与面部发散的骨骼变量无关；（iv）上颌前牙槽高度（UAAH）与FHI呈反向变化，与FMA呈正相关，与PFH无关。
