Stone(1976)曾提出一种快速诊断的简化牙周检查法,可在不到10分钟的时间内指出病员的牙周状况,但他要求事先准备好一套良好的X线全口牙片。新颖的曲面体层摄影技术可以一次曝光。将颌骨和全口牙列显示在一张X线摄片上,获得牙颌系统的全景概念。因此符合牙周病快速诊断的目的。但由于摄影时必须适应曲面情况,而断层的部位也由于牙齿的排列不齐,上下颌骨的解剖形态凹凸不一,以致摄影部位
Stone (1976) proposed a quick diagnosis of a simplified periodontal examination that can identify the patient's periodontal condition in less than 10 minutes, but asked that a good set of X-ray full dental pieces be prepared in advance. The novel surface tomography can be exposed once. The jaw and full mouth dentition displayed in an X-ray film, dental system to obtain the panoramic concept. Therefore, in line with the purpose of rapid diagnosis of periodontal disease. However, due to photography must adapt to the surface conditions, but also due to the location of the fault tooth alignment, the anatomy of the upper and lower jaw uneven, so that the imaging site
