B. Radiographic evaluation
CBCT was used to provide radiographic evaluation immediately, 6, and 18 months postoperative. All CBCT scans were performed in the same radiology centre (Planmeca, ProMax® 3D Max, Helsinki, Finland) using the same parameters (89 kVp, 24 s, 10 mA and field of view 6 cm × 8 cm). For image processing and reconstruction, OnDemand3D was used.
