The incidence of congenital hypodontia is increasing in daily practice. Early diagnosis of this dental disorder and the associated skeletal malocclusions is crucial for successful and stable final rehabilitation.
Comparison of cephalometric findings of patients with hypodontia of 1-4 teeth with the measurement results of the control group without teeth agenesis.
We evaluated the lateral X-ray of 41 patients with 1-4 teeth agenesis selected from patients referred for orthodontic treatment to the Orthodontic Department of the University of Medicine and Pharmacy from Târgu Mureş within a two-year period. The results were compared with the values of the age and sex matched control group.
Bilateral upper incisor and lower bicuspid were missing in most of the hypodontia cases. When looking at the NSGn angle predicting the growth direction of the mandible, statistically significant differences were found between the male (p = 0.012), the front (p = 0.010) and the hypodontia group (p = 0.024) and the control group. Regarding the ANB angle, which shows the sagittal position of the maxilla to the mandible, statistically significant differences were found between the subgroups (women, men, anterior or posterior hypodontia) and the control group.
Larger number of skeletal class 3 and vertical hypodivergent tendency were observed in the hypodontia group. Orv Hetil. 2019; 160(6): 214-219.
在日常临床实践中，先天性缺牙的发病率呈上升趋势。早期诊断这种牙齿疾病以及相关的骨骼错牙合畸形对于最终成功且稳定的康复治疗至关重要。
比较1至4颗牙齿先天性缺牙患者的头影测量结果与无牙齿缺失的对照组的测量结果。
我们评估了在两年时间内从转诊至特尔古穆列什医科药科大学正畸科接受正畸治疗的患者中选取的41例1至4颗牙齿先天性缺牙患者的头颅侧位X线片。将结果与年龄和性别匹配的对照组的值进行比较。
在大多数先天性缺牙病例中，双侧上颌切牙和下颌双尖牙缺失。在观察预测下颌生长方向的NSGn角时，男性（p = 0.012）、前部（p = 0.010）和先天性缺牙组（p = 0.024）与对照组之间存在统计学显著差异。关于显示上颌相对于下颌矢状位置的ANB角，在各亚组（女性、男性、前部或后部先天性缺牙）与对照组之间存在统计学显著差异。
在先天性缺牙组中观察到更多的骨骼Ⅲ类和垂直向下发散趋势。《匈牙利医学杂志》。2019年；160(6): 214 - 219。
