In this module Prof. Christer Dahlin explains the principles of minor bone regeneration procedures. The focus is on the biologic principles of GBR, the importance and the choice of membranes, the characteristics of different bone substitute materials and the potential future developments.

When a tooth is considered to be irrational to treat and needs to be extracted every dentist needs to take decisions on whether to let the socket heal spontaneously with a blood clot or whether to perform alveolar ridge preservation procedures. In this module you are going to learn all the important decision-making factors and the clinical handling after tooth extraction to chose either between spontaneous healing after tooth extraction or immediate implant placement or alveolar ridge preservation procedures.

In every clinical situation, which is scheduled for an implant placement, a decision needs to be taken in regards to the right time after tooth extraction to insert the implant. In this module you are going to learn all the important decision-making factors (anatomical, esthetical, clinical, radiographical and patient centered) to chose the correct timing for implant placement after tooth extraction.

The old restorations showed several ceramic fractures and in some areas the framework was exposed. The patient's main concern was the unesthetic appearance of the anterior crowns in the maxilla due to these chippings.

58-year-old woman desires a total refurbishment by reason of compromised esthetics of her front teeth and missing teeth in the upper left jaw. In addition the bridges in the mandibular left and right show chippings.

Male patient (*1955) treated by Dr. D. Büchi. Functional and esthetic rehabilitation through replacement of insufficient crowns and bridges. Additionally implants were placed in the posterior part, to maximize the masticatory performance.

Female patient *1942 by B. E. Pjetursson, L. Adriaens, N. P. Lang (2004-2006). Comprehensive treatment of periodontitis with full mouth reconstruction.
