Abstract: The objective is to evaluate the clinical effect of flapless immediate implantation combined with immediate restoration in repairing a single traumatic tooth in the maxillary anterior region and explore the clinical factors that influence the effect of implant restoration in the aesthetic area of anterior teeth. A 20-year-old female patient with post-traumatic crown and root fracture of the left maxillary central incisor. The affected tooth was extracted with minimally invasive surgery and replaced with flapless immediate implantation. The temporary restoration was completed on the same day. Seven months later, the digital impression was taken using a 3-Shape oral scanner, and the integrated screw-retained titanium base (Vario-base)-zirconia crown repair was completed. During the follow-up period of 25 months, ideally soft and hard tissue aesthetic effect was achieved in this patient. CBCT and periapical radiographs with paralleling technique showed good osseointegration, sufficient thickness of labial bone plate, and stable level of marginal bones. This case shows that through appropriate clinical operations, the flapless immediate implantation in combination with immediate restoration in the aesthetic area can obtain a good aesthetic restoration effect.
