Unlike bone, which undergoes remodeling by resorption followed by bone apposition, teeth are not subject to physiological remodeling. They are remarkably resistant to physiological remodeling processes. The reason for this is found in the periodontium and cementum. The mechanisms that take effect in this area and the effectiveness of the periodontal system - consisting of gingiva, alveolar bone, periodontium and cementum - after injuries will be visualized in the new scientific 3D film, "Periodontal Regeneration".The visualization of these complex processes is of great interest for academic teaching as well as for the clinician and general practitioner as the cellular interactions are presented in the context of four phases. For the first time scanning electron microscopic images of real cells will be visualized allowing the comparison of their characteristics with computer animated simulations.

Contents: When treating recurrent periodontitis surgically, the challenge is to sacrifice as little soft tissue as possible in esthetically critical areas. This surgical case demonstrates the technique used in patients with narrow approximal spaces.
