[Vertical and horizontal jaw relations in reconstructive dentistry. A critical review].

Despite comprising one of the routine duties of dental practitioners, the methods used for the determination of the vertical and horizontal jaw position differ considerably from dentist to dentist. For the overwhelming majority of patients, however, the techniques generally applied for the maxillomandibular relationship record appear to lead to acceptable results. No method seems to be clearly superior to the other.

[In vitro fracture resistance tests of 3-unit posterior bridges produced by the Procera process].

The aim of this investigation was to evaluate the fracture resistance of three-unit fixed partial dentures manufactured with the Procera-System in vitro. Metal abutments representing the teeth 25 and 27 were prepared with a 90 degrees circumferential internally rounded shoulder. The abutments were duplicated with polyvinysiloxane, and master dies were fabricated.
