Abstract

The reliability of two panoramic x-ray machines (Philips Orthoralix SD Ceph and Gendex Panelipse II) for determination of the location of the mandibular foramen was studied with the use of human dry mandibles. A significant correlation was found between the location of the mandibular foramen in the radiograph and the narrowest anteroposterior dimension of the ramus. A linear logistic regression equation was developed that could predict the actual location of the mandibular foramen from the radiographs. This finding will improve treatment planning of surgical splitting or fracturing of the ramus in cases that require orthognathic surgery provided the surgeon is aware of which panoramic machine was used. The Philips Orthoralix SD was found to be more reliable for this purpose than the Panelipse II (R² = 0.94 andR² = 0.87, respectively, in the vertical dimension and R² = 0.87 and R² = 0.75, respectively, in the horizontal dimension.

全景x线片上下颌孔的位置

本文研究了两种全景x线机(Philips Orthoralix SD Ceph和Gendex Panelipse II)测定下颌孔位置的可靠性，并使用人干下颌骨。在x线片上发现下颌孔的位置与支最窄的前后尺寸有显著的相关性。建立了一个线性逻辑回归方程，可以从x线片预测下颌孔的实际位置。如果外科医生知道使用的是哪种全景机器，这一发现将改善在需要进行正颌手术的情况下手术分支分裂或骨折的治疗计划。Philips Orthoralix SD在垂直维度上比Panelipse II更可靠(R2 = 0.94和R2 = 0.87，在水平维度上分别R2 = 0.87和R2 = 0.75)。
