After this course the students are familiar with the principles of the surgical therapy of periodontal disease. They know which kind of operation is required in special clinical cases and how it is prepared.
Both theoretically and practically, the students learn different flap techniques which allow the removal of concrements and pathogenic microorganisms under visual inspection.
Another item of this course is the resective therapy. By removing parts of the bone a positive bone architecture is built, which leads to a better attachment of the soft tissue. The resective therapy of furcation defects, which contains odontoplasty, root amputation/hemisection and premolarization, is also taught and practised.
The students learn new possibilities and limits of regenerative therapy, which aims at the new formation of periodontal structures. Therefore, bone replacement materials are used to serve osteogenesis, osteoinsuction and osteokonductivity. These materials have different advantages, disadvantages and indications regarding their origin (autologous, allogenic, xenogenic). All their properties are explained in detail.
The „guided tissue regeneration“(GTR) stops the immediate proliferation of the rapid recovering epithelium cells in order to provide enough time for the slow recovering periodontal cells.
This is enabled by a mechanical border. For this purpose, different absorbable and non-absorbable membranes are available. Enamel matrix derivatives such as Emdogain® are available to stimulate the new formation of root cementum. By means of a hands-on-training the handling of these materials is taught.
Furthermore, the theoretical and practical background of the surgical methods of recession coverage is taught. Here the recession is assigned to the corresponding Miller class in order to predict both treatment success and surgical possibilities.
The students know which conditions (oral hygiene, no inflammations, removal of root caries and fillings) need to be fulfilled before a surgery can be done. Depending on the origin of the recession (anatomical like tooth shape or muscle pulls or external influences like trauma or inflammation) different techniques are used.
There are pedicle flaps including rotational pedicels and coronally advanced flaps, as well as free grafts (epithelial and subepithelial).
Furthermore, frenotomy and frenectomy are applied.
