Three-dimensional (3D) technology has gained wide acceptance in dentistry. It has been used for treatment planning and surgical guidance. This case report presented a novel treatment approach to remove and preserve the cortical bone and root-end resection during periapical surgery with the help of cone-beam computed tomography (CBCT), computer-aided design, and 3D printing technology. A 22-year-old male patient presented with a large periapical lesion in the right maxillary central and lateral incisors was referred for endodontic surgery. The data acquired from a preoperative diagnostic CBCT scan and an intraoral scan were uploaded into surgical planning software and matched. A template that could be used to locate root ends and lesion areas was virtually designed based on the data and was fabricated using a 3D printer. With the guidance of the template, the overlying cortical bone was precisely removed and preserved, and apicectomy was performed. The patient was clinically asymptomatic at a 6-month follow-up review. Six months after the surgery, the lesion was healing well, and no periapical radiolucency was observed on radiographic examination. The digitally designed directional template worked in all aspects to facilitate the periapical surgery as anticipated. The root ends were accurately located and resected. The surgical procedure was simplified, and the treatment efficiency was improved. This technique minimized the damage and reduced iatrogenic injury.
