Preoperative measures
COMPLICATIONS
Thorough medical and dental history was taken for all patients to determine the correspondence of the patients to the eligibility criteria. Written consent forms were signed by patients’ guardians/parents after clarifying the treatment plan and possible complications. A maxillary and mid-face CBCT image was captured as a baseline record using CBCT machine (Scanora® 3D with AutoSwitchTM, Soredex, Helsinki, Finland). The exposure parameters were 85 kVp, 15 Ma, and 6 cm FOV.
