Objective: To summarize the key points in extraction of embedded supernumerary teeth in children under intravenous anesthesia. 前言:目的:探讨在浅静脉麻醉下儿童埋伏多生牙拔除的临床技术要点。
Methods X-ray dental film and panoramic pantomogram were used to determine the location of embedded supernumerary teeth on bases of the geometrical principle of X-ray photography. 方法通过拍摄X线牙片及全景片,结合临床检查,利用X射线照相中的几何学原理确定多生牙的位置,以确定手术入路,然后拔除。
Objective: This study aimed to evaluate the clinical value of digital pantomogram in identification the position of gnathous unerupted supernumerary teeth. 目的:评价数字化断层片在颌骨埋伏多生牙临床定位中的应用价值。
Objective To discuss the application of SCT ( scan and three-dimensional reconstruction technic) in the wholly impacted supernumerary teeth. 目的探讨多层螺旋CT在颌骨埋伏多生牙诊断和定位中的应用价值。
This technique is applied to investigate 9 cases of supernumerary and impacted teeth. 应用该方法检查9例患者的骨内埋伏多生牙和阻生牙。
Objective To analyse the clinic and pathologic features of 100 embeded supernumerary teeth, to find out the rule of cystic change of supernumerary teeth and its relationship to malocclusion, and to present the methods of therapy. 目的通过100例埋伏多生牙的临床与病理分析,寻找埋伏多生牙囊变的规律及与错牙合畸形的关系,提出相应的治疗方法。
Methods Slices from 32 supernumerary teeth were observed under light microscope and compared with normal teeth. 方法选择32颗多生牙,在光镜下观察其切片及磨片的组织学结构并与正常牙对照。
Result: One case originated from the supernumerary teeth on the floor of left nasal cavity, and the other left reversed lateral incisor. Both had the medical history of upper lip and para-nose swelling. 结果:1例起源于左鼻腔底额外牙的含牙囊肿,另1例起源于左鼻腔底倒生侧切牙的含牙囊肿,均有同侧上唇、鼻旁的反复肿胀史。
The purpose of this study is to investigate the incidence and mostly happened area of the congenitally missing teeth and supernumerary teeth in Beijing adolescent in order to approach the relation between the anomaly of tooth number and human evolution. 本文调查了北京地区青少年先天缺失牙和多生牙的发生率、好发部位,探讨先天牙齿数目异常与人类进化之间的关系。
The Clinical and Pathologic Study of Embeded Supernumerary Teeth 埋伏多生牙囊变的临床与病理研究
Conclusion The 4 approaches are especially useful to the embedded supernumerary teeth in anterior maxilla. 结论4种径路均是上颌前部埋伏多生牙拔除的有效方法。
The accurate positions of a wholly impacted supernumerary teeth in bone was ( obtained) based on the measured distances of image between the tooth and the tissues around by the ruler on SCT. 根据CT标尺测量图像与周围结构关系的距离,以确定骨埋伏多生牙的确切位置。
It is the most commonly that supernumerary teeth are impacted in maxillary anterior region with considerable clinical significance. 上颌前部骨埋伏多生牙是多生牙中最常见的一类,临床意义也较大。
Clinical Analysis of Extraction of 36 Cases with Embedded Supernumerary Teeth In the Maxilla 上颌骨埋伏多生牙36例拔除的临床分析
The study of X-ray location method of the embedded supernumerary teeth in fore alveolar bone of maxilla of children 儿童上颌前部埋伏多生牙X线片定位方法的探讨
Clinical Types and Treatment of Embedded Supernumerary Teeth in Maxilla Anterior Region in Children 儿童上颌前牙区埋伏多生牙的临床分型与治疗
Objective: To study the clinical types and treatment of embedded supernumerary teeth in maxillary anterior region in children. 目的:探讨儿童上颌前牙区埋伏多生牙的临床分型及手术处理。
Results the positions of wholly impacted supernumerary teeth in the complex maxilla or mandible anatomy structure images were clear reflected by SCT scan and 3D reconstruction. 结果螺旋CT扫描及三维重建能清晰显示复杂的颌骨解剖图像以及骨埋伏牙与周围结构的关系。
