Abstract

Aim and objective: The objective of therapy was to replace the missing teeth with a restoration that closely adhered to the natural teeth and soft tissue contour to provide an esthetic outcome. Case description: A 19-year-old male reported a failed fixed partial denture (FPD) in the maxillary left central incisor. The abutment extended to the maxillary right central incisor and the maxillary left lateral incisor. Radiographic examination revealed that the neighboring maxillary right central incisor abutment was nonrestorable. The treatment plan was the extraction of the maxillary right central incisor with socket preservation, modification of the pontic sites for placement of an ovate pontic for the replacement of the missing maxillary upper central incisors with an FPD with the maxillary lateral incisors serving as the abutment teeth. The pontic sites were corrected with a U-shaped flap extended 5 mm palatal from the mid-crestal line. The incision was avoided at the interdental papilla area. The facial flap was elevated. The facial soft tissue was vertically tunneled. The flap was flipped into the facial tunnel and stabilized with horizontal nylon matrix sutures. The surgical site was stabilized with a provisional FPD with an ovate pontic. The final restoration was a full zirconia facial veneered FPD. Results: Surgical site showed significant healing with a natural emergence profile, and interdental papillae filling the gingival embrasure, showing no evidence of recession. At the 1-year follow-up, the gingival thickness improved and the pontic emergence profile was natural. A very stable result for soft tissue volume and interdental papillae were seen. Conclusion: According to the result obtained with rotational flap, it can be used for small anterior defects with promising results, without the need for bone graft procedures or additional tissue graft. Clinical significance: With proper case selection, the use of a rotational flap with a tunnel technique and an ovate pontic in the anterior esthetic region is an alternative treatment option that can successfully restore masticatory and esthetic function.
