_Autogenous bone block grafts, bone graft- ing material or a combination of both can be used torestoreanimplantsiteofadequatedimensions in an atrophied maxilla. If the vertical height of the bone is inadequate in the posterior region, a sinus floor lift is often indicated to stabilise the implants safely. In the case presented here, surgical treatment based on Prof. Fouad Khoury’s1, 2 biological con- cept for bone grafting using a combination of autogenous bone block grafts and particulate bone chips is described. The case report also describes the layering technique as part of a sinus floor lift in conjunc- tion with bone grafting material. The objective of the treatment is a restoration with long- term stability and a good aesthetic result. An implant-supported bar-latch design based on Dr Friedrich-Wilhelm Pape’s prosthetic concept (Schellenstein concept) was used.3 I case report _ restoration of atrophied maxillae Fig. 1_The initial clinical situation of the old telescopic restoration.
