| overview its causes are manifold. This is illustrated by the two following examples: Case 4: Augmentation failure The following case presents early failure of an im- plant-based restoration. A sinus lift was performed at a maxillofacial practice in order to later insert im- plants for the rehabilitation of a free-end situation. Both augmentation and healing phase were un- eventful. Implant insertion was planned to be performed in the same practice. However, it was finally carried out in a different practice upon request of the patient. The graft, consisting of a mixture of synthetic bone substitute and autogenous bone was assessed to be healed and loadable following DVT control. In addi- tion, the insertion of three implants and their pros- thetic loading were uneventful and without any spe- cial occurrences. After six months, the patient experienced side ef- fects and inflammation of the periimplant soft tis- sue: a complete failure of the periimplant soft tissue sleeve with the highest-possible probing depth and symptoms such as pain had occurred and ultimately lead to the removal of the implant restorations. Not only was this implantological T a tragedy, but it also can be rightfully declared a total failure (incidentally also starting with a T), moreover one at a very early stage (Figs. 22–29). In conclusion, this case illustrates a classical early implant failure. Case 5: Total failure The final case presentation is an example of a late failure. The 59-year-old patient was characterised by, firstly, being constantly stressed, and, secondly, never having any time to spend for anything. His leading role in sales took its toll and was sometimes Fig. 15: Edentulous maxilla 1996. Fig. 16: Bar in the mouth 1996. Fig. 17: Partial prosthesis before integration. Fig. 18: Integration.
