(a) and (b) The customized surgical template was 1.8 mm thick layer average offset based on the teeth/mucosa/bracket contour profiles and ranged from half canine to second molar. The surgical template height was designed to cover the entire occlusal surface and extend to half the crown height to protect the orthodontic brackets bonded onto each tooth. The miniscrew drill paths and guided cylinders were designed 5.3 mm in diameter and 6 mm in height.
