implants2_2010 The retromolar space is chosen here in more than 70 per cent of cases. Until now exclusively block grafts have been used. _Case description The 36 year old patient wants the gaps in his teeth in the regions 031, 041 to be filled with im- plantsduetohisotherwiseintactdentition.How- ever in this situation the question is raised of whether implantation and necessary augmenta- tion of the crestal jaw line can occur synchro- nously.It was planned for the patient to have au- tologous bone adhered in the region of the 031 vestibular. Hereby the right retromolar space and the right tuber area were considered as donor areas. The patient could be assured pre- operatively that an extraction defect of bone ex- traction would only involve few complaint symptoms. Interoperatively the crestal incision was begun in the areas 031 and 041. After form- ing a minimally invasive mucoperiosteal flap, in particular region 031 showed strong vestibular atrophies. Initially implant drilling was carried out and the bore shaft was extended using bone condenser, i.e. the periimplantational bone was condensed.Subsequently,theimplantbodieswere inserted. Here it became obvious that the implant Fig. 7_the implant body in region 031 must be vestibularly covered with au- tologous bone over approx. 2/3 of its surface.

A “two spade drill” is excel- lently suited to bone extraction. Fig. 10_Bone excavation via simple shaft drilling with the conventional “two spade drill”.
