上颌磨牙炎症期拔牙后种植病例的CBCT影像分析

摘要/Abstract

摘要： 目的通过CBCT对上颌磨牙炎症期拔牙后种植病例进行影像分析，探讨上颌磨牙炎症和上颌窦炎症的关系以及种植时机对种植体存留率的影响。方法对73人73例上颌磨牙炎症期拔牙后种植病例的CBCT影像进行分析，将上颌磨牙炎症与上颌窦底的关系分为三组（A组：炎症进入上颌窦内；B组：炎症与上颌窦相接；C组：炎症与上颌窦有一定距离），观察其与上颌窦炎发生的相关性，术后通过测量CBCT冠状面种植体周围骨吸收程度评定种植疗效。结果本实验中A组上颌窦炎发生率100%；B组上颌窦炎发生率77.1%；C组上颌窦炎发生率42.9%。73例炎症期的上颌磨牙种植后有2颗植体脱落，均为即刻种植病例，其他病例CBCT影像分析良好。结论炎症与上颌窦的距离越小发生上颌窦炎的风险越大。拔除病灶牙有利于上颌窦炎的恢复。炎症期拔牙后即刻种植的存留率低于早期种植和延期种植。

Abstract: Objective To analyze the image of the implant cases after extracting inflammatory maxillary molar by CBCT, and discuss the relationship between the degree of inflammation and maxillary sinusitis and the effect of planting time on the survival rate of implants. Methods The study analyzed CBCT images of 73 patients with inflammatory teeth. According to the relationship between inflammation and the bottom of maxillary sinus, there were three groups(Group A: inflammation entered into the bottom; Group B: inflammation connected with the bottom; Group C: inflammation had a certain distance to the bottom), through the measurement of the vertical distance from inflammatory maxillary molar to maxillary sinus bottom to observe their correlation, by measuring the bone resorption degree of CBCT coronal plane to assess the efficacy of planting. Results The incidence of maxillary sinusitis in group A was 100%, the incidence rate of group B was 77.1%, and the incidence rate of group C was 42.9%. There were 2 implants off in the 73 implant cases, which were immediate implant cases. The other cases were good after CBCT image analysis. Conclusion The smaller the distance between inflammation and maxillary sinus, the greater the risk of maxillary sinusitis is. The removal of the diseased teeth is conducive to the recovery of maxillary sinusitis. The survival rate of immediate implant placement is lower than that of early implant placement and delayed implant placement.
