儿童上颌前部埋伏多生牙临床定位和拔除的研究

The Study of Extraction and Location of Embedded Supernumerary Teeth in Maxillary Anterior in Children

目的:探讨埋伏多生牙的定位与拔除方法。方法:临床门诊患者128例,通过定位X线牙片结合临床检查,分析判断埋伏牙的位置,确定手术进路,然后拔除。结果:128例患者经术前定位,83例位于腭侧,15例位于唇侧,30例位于牙列中,与术中所见一致,无损伤邻牙及伤口感染等并发症发生。结论:通过定位X线牙片对埋伏多生牙进行定位,是一种简便易行的方法,便于选好手术进路。

Objective：To investigate the approach of the location and extraction of embedded supernumerary teeth. Methods： 128 cases of embedded teeth were collected. The tooth radiogram combined with clinical examination was applied to localize the embedded teeth. According to condition and position of the teeth, the operative approach was designed to extract the teeth. Results：Before operation, 128 cases were classified as 83 palate side cases, 15 lip side cases and 30 dentition cases, which was identical to the operative findings. There was no serious complications such as injury in adjacent teeth and wound infection occured. Conclusion： Tooth radiogram is a simple and feasibe technique for location of embedder supernumerary teeth and selecting correct operative approach.
