Rehabilitation of a periodontally compromised case using the conical crown system. Part II.

The aim of this two-part treatment series is on the one hand to emphasize the difficulties a clinician is confronted with when planning complex cases, and on the other hand to reveal the rationale supporting the final treatment plan selection. Among the challenging cases to be considered are periodontal compromised rest dentitions requiring prosthodontic rehabilitation. For these patients the decision-making process deals with the indications and limitations of both the fields of fixed and removable prosthodontics.

Fracture resistance of different zirconium dioxide three-unit all-ceramic fixed partial dentures.

Objective: This study evaluated the fracture resistance of different zirconia three-unit posterior all-ceramic fixed partial dentures before and after fatigue loading.

Material And Methods: Forty-eight zirconia three-unit posterior all-ceramic fixed partial dentures were fabricated using different manufacturing systems and conventionally cemented on human teeth. The restorations were divided according to the system used for manufacturing the frameworks into 3 groups of 16 specimens each (DCS, Procera and Vita CerecInlab).
