Objectives: Use of a soft tissue graft for recession coverage at tooth 23 and for gingival augmentation. Content: 1. Incision around tooth 23, intra-sulcular preparation, mobilization of coronal sliding flap, and pre-flap preparation. 2. Root smoothing, reduction of ground cavity with diamond burs from Perioset system. 3. Preparation and harvesting of connective tissue flap from palate, Emdogain application, and wound closure. 4. Placement of interrupted interdental sutures for fixation of connective tissue flap.

Contents. Aggressive periodontitis leads to early and extensive loss of periodontal supporting tissue. Controlling the infection is of serious importance to avoid further loss of attachment. The surgical procedure is difficult, especially if the tissue is already severely damaged. The challenge for the surgeon is to protect and conserve the tissue as much as possible.

Bone transplants, bone replacement materials, and nonresorbable and resorbable membranes have been and still are being used. In a new therapeutic approach to periodontal regeneration, the root surface is conditioned using an enamel matrix protein derivative (Emdogain, Biora). The protein complex stimulates the regeneration of root cement, which in turn leads to the regeneration of bone and collagen fibers. Since the early 1980's, Professor Lars Hammerström's Swedish research team has performed extensive research and studies on this method and its mode of action. Emdogain is now used for treatment of vertical bone defects and furcation defects. The exposed root surface is first carefully scaled using handheld instruments or a rotating, fine-grain diamond drill. PrefGel EDTA suspension (Biora) is then applied for 2 minutes, then thoroughly rinsed with physiological saline solution. The EDTA suspension serves to remove the smear layer and opens the dentinal tubules, leading to improved binding of Emdogain to the root surface. Emdogain is applied to the blood- and saliva-free root surface immediately after rinsing. Finally, the wound is sutured closed.

The old reconstructions have to be replaced. But how? A challenging case treated by Dr. Sven Mühlemann, University of Zurich.

Before starting the full-mouth reconstruction, the oral-maxillary sinus fistula (oroantral fistula) has to be closed.

In this clinical case session you are going to learn how to plan and execute treatment in a partially edentulous patient situation applying implants within the overall reconstructive treatment concept. In particular you will learn the importance of the preparatory phases of therapy and to plan and treat with the prosthetic aim in mind.

Male patient *1986 by Dr. V. Kokovic (02-10/2007). Anterior single implant placement after orthodontic extrusion and ridge preservation.

This patient (*1971) treated by Dr. Büchi, came to our clinic for a replacement of her poorly fitting removable prostheses. Additionally severe orthodontic problems, i.e. a slanting occlusion plane are bothering the patient and are in need of treatment.

The broken central incisor 21 was replaced with an implant-supported crown. The diastema could be closed with an etch-piece on 11.

Female patient (*1948) suffering from periodontitis wants to reach a state of complete oral health and ideal masticatory performance.
