Immediate provisional restoration of a single-tooth implant in the esthetic zone: A case report

Immediate implant restoration of single implants may demonstrate a positive effect on peri-implant soft tissue. Placement of a provisional restoration following implant surgery can create soft tissue contours that resemble normal gingival topography before placement of the definitive prosthesis. This article describes a staged approach of the mandibular permanent right central incisor, which was congenital missing. The proper space for restoration of the missing incisor was created through orthodontic treatment. The scheduled implant site was reconstructed using autogenous bone harvested from the chin region. After a healing period of four months, an implant was installed with the connection of a fixed provisional crown to a prefabricated temporary abutment. The soft tissue around the implant healed according to the contours of the provisional restoration and the emergence profile was used to duplicate the definitive restoration. Peri-implant esthetics was achieved through the staged approach and immediate restoration of the implant.

摘要單顆植體立即性贋復對植體周圍軟組織有正向的作用。在置放永久贋復物前，植牙手術後隨即製作的臨時贋復物可創造出近似自然牙牙齦形態的軟組織外形。本文敘述如何階段性的處理右下正中恆門齒先天缺失伴隨齒槽骨缺損之病例。先經由矯正治療創造適當的贋復空間給先天缺失的下顎門齒。預計放置植體處的無牙嵴缺損以從下頷取得的自體骨做重建。經四個月的癒合期，置入人工植體後隨即接上預製的暫時支台柱及固定的臨時牙冠。調整臨時贋復物的外形來塑形植體周圍軟組織，並複製其萌出外形以製作最終贋復物。植體周圍美觀經此階段性的處理與植體立即性贋復而達成。
