The simple plate made preoperatively was used for flapless im- plant surgery. Temporary restorations induce soft tissue forming and ultimately achieve better aes- thetic results. A middle aged female patient presented at Dalian Stomatological Hospital for a consultation to repair the continuous absence of maxillary anterior teeth (11, 21, 22) with implants. The oral examination and the cone beam computed tomography (CBCT) were carried out and an impression was obtained. When the plaster cast was available, a diagnostic wax-up was made and hot press was used to form a simple plate. A non-impression transfer device called (die) wasmadeontheplastermodel.Flaplessimplantsur- gery was conducted with the guide of the plate; two bone-level implants were placed. The immediately fabricated prosthesis was placed on the same day. The definitive prosthesis was placed after a healing time of six months. During the following period, individual implant stability and soft tissue response to the provisional prosthesis were good. When the definitive prosthe- sis was done after six months, excellent aesthetic results were achieved with the papilla by filling the interdental space, resulting in an absence of the black triangle and a harmoniously scalloped gingi- val margin.
