ABSTRACT

In this paper we present all the steps in the restoration of an edentulous maxilla with implant-supported fixed prostheses cemented over six osseointegrated implants, graphically docu- menting the surgery, the preparation and the placement of the prosthesis.

Clinical case: A 59-year-old female patient with no relevant clinical history. The patient presents a partial resin prosthesis in the upper arch retained by three teeth with cavities and pe- riodontal disease […]. After the study, we decided to restore the upper jaw with an implant-supported metal-ceramic prosthesis cemented on six pillars on implants […]. We placed six MG Inhex® (Mozo-Grau S.L., Valladolid. Spain) implants. The design of the internal connection implant will allow us to minimise peri-implantation bone loss and achieve better aesthetics, especially when the anterior section is involved, as is the case here.

Due to the narrow width of the residual alveolar bone, we needed to perform bone expansion via expansion osteotomes and self-tapping expanders, and we placed abutments at a 15o an- gle for Inhex (Mozo-Grau S.L.) to correct the observed disparallelism.

Conclusions: Given the multitude of possibilities which restorative Implantology allows today, we must know their advantages and disadvantages to individually choose the most appropriate one in each situation. As we see in this case, if the residual maxillary alveolar ridge and the surgical technique allow us to place a minimum of well distributed fixations, implant-supported restoration with a cemented metal-ceramic prosthesis is a good restoration choice, as far as comfort and aesthetics are concerned, in addition to correcting parallelism.
