Complication rate with prosthodontic reconstructions on ITI and IMZ dental implants. Internationales Team für Implantologie.

The aim of this study was to compare the complication rate of two implant systems with different prosthodontic concepts: rigid conical or resilient support of the suprastructure. In 66 patients, 138 ITI implants were inserted whereas 31 patients received a total of 50 IMZ implants. Over an average observation period of 3.

Intraoral repair of fiber-reinforced composite fixed partial dentures.

Statement Of The Problem: Fractured composite facings may result in replacement of a fixed partial denture unless a reliable intraoral repair method can be provided.

Purpose: This in vitro study tested the quality of an intraoral repair method for fractured facings of fixed partial dentures made of a fiber-reinforced composite system.

Material And Methods: Shear bond strengths of a light-curing composite to a fiber-reinforced composite material were determined after different mechanical surface treatments.

Colour stability of visible light-curing hybrid composites.

The colour stability of six visible light-curing fine hybrid composites was evaluated after 24 and 120 hours of irradiation using a xenon lamp. Discoloration of four shades of each material (A1, A2, A3.5 and B2- Vita shade guide) was measured using a reflection spectrophotometer with the CIE-L*a*b* system.
