This article is the author of the grass-roots hospital to create conditions for Begg orthodontic technology bit by bit adjournment. 1. Homemade head Locator Begg orthodontic technology first for X-cephalometry in order to correctly diagnose and predict the efficacy. According to the principle of cranial positioning, the design of a simple wooden locator (Figure 1,2). Radiological chest radiograph for fixed skull locator, the first lateral radiography. Patients close to the chest frame, sitting or standing sideways, the 20.32 × 25.4cm tablets on the chest frame alignment head lateral,
