【摘要】：通过口腔锥形束CT(CBCT)扫描、三维重建和测量上颌第一磨牙与上颌窦及周围牙槽骨的距离,研究上颌第一磨牙即刻种植的可行性。在CBCT系统的软件里对200例上颌骨影像数据进行测量分析,测量上颌第一磨牙牙槽嵴顶至上颌窦底的距离,根分叉顶至上颌窦底的距离,根分叉顶至颊、腭侧牙槽骨表面的距离,牙根间隔牙槽骨在根颈处、根中处和根尖处的宽度,腭根根尖至上颌窦底的距离。上颌第一磨牙牙槽嵴顶至上颌窦底的距离男性平均为(12.80±2.59)mm,女性平均为(11.29±2.18)mm;根分叉顶与上颌窦底之间的骨高度男性平均为(9.15±0.49)mm,女性平均为(9.07±0.46)mm;上颌第一磨牙腭根根尖与上颌窦底之间骨高度男性平均为(2.38±0.69)mm,女性平均为(2.10±0.51)mm。上颌第一磨牙的即刻种植,建议选择牙根间隔牙槽骨为植入位点;腭根的拔牙窝直接植入种植体需慎重考虑。
[Abstract]:The distance between the maxillary first molar and the maxillary sinus and its surrounding alveolar bone was reconstructed and measured by the CT CBCT scanning of the oral conical bundle to study the feasibility of immediate implant of the maxillary first molar. The maxillary image data of 200 cases were measured and analyzed in CBCT software. The distance from the top of the alveolar ridge to the bottom of the maxillary sinus, the distance from the top of the root bifurcation to the buccal and the surface of the alveolar bone on the palatine side were measured. The width of the alveolar bone at the root neck, the middle and tip of the root, and the distance between the apex of the palatine root and the floor of the maxillary sinus. The average distance between the alveolar crest of maxillary first molar and the floor of maxillary sinus was 12.80 卤2.59 mm for males and 11.29 卤2.18 mm for females, the height of bone between the top of root bifurcation and the floor of maxillary sinus was 9.15 卤0.49 mm for males and 9.07 卤0.46 mm for females, respectively. The average height of bone between the sinus floor was 2.38 卤0.69 mm in males and 2.10 卤0.51mmmm. in females. For the immediate implant of maxillary first molar, it is suggested to select the alveolar bone of the root septum as the implant site, and the implant should be carefully considered for the extraction of the palatine root.
