The location of refrence points and a control group sample. a The reference bars (*) and points (blue dots) on the distal segment of the mandibular model. The cross-shaped reference bars (*) were designed at the molar (to represent the posterior and dental area) and chin region (to represent the anterior and skeletal area). The reference points (blue dots) at the end of each bar on the simulated and experimental models were compared to measure distraction accuracy. b An experiment model in the control group with the conventional distractor, which was put in place by bending and contouring the fixation plate (★) to the surface of mandible with the help of a positioning guide
