| Abstract: | This lecture will show you what you can do to improve a weak bone to avoid an early functional mistake or failure of the total reconstruction ... We will discuss how to avoid esthetic failues, an unpleasent situation for both the patient and the dentist, that are often due to lack of bone right from the beginning. Finally we will discuss the option to place an implant in a sub-crestal position which is only possible if you use an implant that has a stable cone connection. The cone connection will avoid any bacterial release, and will therefore avoide any bone loss in the cervical region caused by this bacteria contamination. With this concept we can achieve long lasting esthetic results. |
