ABSTRACT
The replacement of lost teeth and tooth-bearing tissues with implant-supported prostheses often forced both dentist and technician to choose removable overdentures because they were the only treatment modality possible. By means of a clinical case, this article demonstrates a new approach in framework design that not only expands the limitations of conventional ceramometal implant prostheses, but also eliminates a great number of the hazards that cause implant failure with a new type of suprastructure. The technique enables both the clinician and the technician to apply all of the esthetic possibilities of tooth-supported metal ceramic crown and bridge techniques. This technique combines screw and cementation retention without changing the original treatment protocol. A new casting technique introduced by Sonntag and a new specially developed alloy was used. Essentially, the reconstructive body has been broken down into a screw-retained soft tissue/bone-replacing part using a one-piece casting technique, and a crown-replacing part to be provisionally cemented with a large variety of new possibilities.

The experience gained by the training of dental assistants using individual education programs shows that there is a need for similar training and education of dental hygienists. The presently existing education programs in this field are not related specifically to training of periodontal procedures and prophylaxis and are insufficient for the treatment of patients with periodontal diseases. This was also the conclusion of a committee for dental auxiliary personnel that was recently initiated by the German Society of Periodontology.
