[Clinical results and material behavior of composite, ceramic and gold inlays].

Laboratory-manufactured gold, ceramic and composite inlays were compared with the CAD/CAM produced CEREC inlay experimentally and clinically. The following systems were examined: Dicor, Optec, Hi-Ceram, Du-Ceram, Cerec, Kulzer, Coltene, SR-Isosit composite inlays, and gold inlays (Degulor C) with adhesive fixation (group I) and with zinc oxide phosphate cement (group II). In the clinical trial inlays in 270 teeth were re-evaluated in a total of 73 patients after 2.3 to 5 years. After 3 years the results obtained with Optec, Hi-Ceram and the Coltene composite inlay were less favorable than those of other systems--statistically however, this difference was of rather low significance (p less than 0.05). Fractures of ceramic inlays occurred in 6 cases within 8 months. 10 failures of ceramic and composite inlays were due to secondary caries.

[Periodontal aspects of removable partial dentures].

Periodontal pre-treatment of patients receiving partial dentures should involve three phases: initial therapy; periodontal surgery; home care. For periodontal surgery and/or prosthodontic treatment using precision materials, e.g. telescope retainers, the API (approximal plaque index) should not exceed 30%. To prevent further loss of gingival attachment due to iatrogenic irritation by the dentures preparation of abutments should consistently the para- or supragingival. In patients with few residual teeth telescope retainers, which can be cemented for definitive fit if indicated, are the treatment of choice.
