Abstract: Objective To observe the esthetic effect and soft tissue stability of the final restoration by using the temporary crown to shape the soft tissue around the implant in the anterior maxilla. Methods In this study, 21 cases of upper anterior maxilla which needed to be implanted were selected. Temporary crowns were carried out immediately or delayed after dental implant. Soft tissues around the implants were shaped. After soft tissues were stabilized, they were duplicated by the custom impression coping technique and the final restorations were completed. The pink esthetic score (PES) was used to evaluate the esthetic effect of soft tissues around the implants. Results Eleven patients with PES≥12, 9 patients with 8≤PES≤11, obtained better esthetic effect. The implant in anterior maxilla in one case supported fixed bridge reparation. Due to the horizontal absorption of alveolar bone, the soft tissues receded. So in the later stage, esthetic treatment was carried out through Gingival Porcelain. Twenty-one patients were observed for one year after final restoration. Then PES was again used to evaluate. The results showed that all the cases obtained good aesthetic effect. Conclusion After anterior teeth implantation, the soft tissues can be shaped by temporary crowns, which can adjust the soft tissues to a better appearance and a stable shape. This method is necessary to implant in the anterior maxilla and is worth popularizing in clinical practice.
