目的:使用VR网格对上颌窦体积进行三维评估,并将其与上颌犬的体积相关联,侧切牙,受累和未受累部位的牙槽骨和骨骼尺寸。
方法:在一项回顾性横断面研究中,分析了100例单侧腭阻生上颌尖牙患者的锥形束计算机断层扫描。犬类,侧切牙,使用DICOM文件测量嵌塞侧和非嵌塞侧的上颌窦体积,用三维软件(MIMICS)和VR网格来完成这一评估。
结果:受累侧男性和女性患者的犬切牙和侧切牙体积无明显差异(p>0.05),而上颌窦体积显示统计学差异(P=0.022)在受累侧男性(12642±810)和女性(12481±650)患者之间。在未受影响的男性患者中,犬齿和侧切牙体积之间发现了很强的正相关(r=0.420**,P=0.008)和受影响的侧面(r=0.334*,P=0.038)。
结论:犬体积无显著差异,前牙槽脊的高度(AARHMLI),和上颌侧切牙的前牙槽(ADAHMLI)在受累/非受阻侧,但它显示了男性和女性患者的阻生侧和非阻生侧的侧切牙体积的统计学差异。上颌窦体积显示,男性和女性在受累侧和未受累侧之间存在统计学差异。
OBJECTIVE: Three-dimensional evaluation of maxillary sinus volume using VR mesh and correlate it with the volume of maxillary canine, lateral incisor, and dentoalveolar and skeletal dimensions in both impacted and non-impacted sites.
METHODS: In a retrospective cross-sectional study, cone beam computed tomography scans of 100 patients with unilateral palatally impacted maxillary canine were analyzed. Canine, lateral incisor, and maxillary sinus volumes on the impaction and non-impaction sides were measured using DICOM files, with three-dimensional softwares (
MIMICS) and VR mesh to accomplish this assessment.
RESULTS: There were no significant differences in canine and lateral incisors volumes between male and female patients in the impacted side at (p > 0.05) while the maxillary sinuses volume revealed a statistical difference (P = 0.022) between male (12642 ± 810) and female (12481 ± 650) patients in the impacted side. A strong positive correlation was found between canine and lateral incisor volume for male patients in the non-impacted (r = 0.420**, P = 0.008) and impacted sides (r = 0.334*, P = 0.038).
CONCLUSIONS: There were no significant differences in the canine volume, the height of the anterior alveolar ridge (AARHMLI), and anterior dentoalveolar (ADAHMLI) of maxillary lateral incisors in the impacted/non-impacted side, but it showed a statistically significant difference for the lateral incisors volume in the impacted and non-impacted sides for male and female patients. The maxillary sinus volumes revealed a statistical difference between males and females in impacted and non-impacted sides.
