An in vitro evaluation of 2 methods for retrieving fractured abutment screw fragments from the intaglio of 4 different implant systems.

Statement Of Problem: When an abutment screw fractures, there is no standardized technique for retrieving it from the intaglio of the dental implant.

Purpose: The purpose of this in vitro study was to assess the relative efficacy of a commercially available screw fragment retrieval kit with a range of standard dental instruments in regard to success and retrieval time. In addition, the effects of other variables on the success rate of screw fragment retrieval and the retrieval time required were also investigated.

The effect of a decontamination protocol on contaminated titanium dental implant surfaces with different surface topography in edentulous patients.

To investigate if it is possible to achieve complete decontamination of dental implant surfaces with different surface characteristics. Twelve implant pieces with an Osseotite surface and 12 implant pieces with a Ti-Unite surface were attached on to the complete lower dentures of six patients and were allowed to accumulate plaque for 30 days. When retrieved, the implant decontamination protocol used, involved both mechanical (PeriBrush™) and chemical (3% HO) decontamination.

Immediate loading of occluding definitive partial fixed prostheses vs non-occluding provisional restorations - 3-year post-loading results from a pragmatic multicentre randomised controlled trial.

Purpose: To compare the clinical outcome of dental implants restored with definitive occluding partial fixed prostheses within 1 week after implant placement with immediate non-occluding provisional restorations to be replaced by definitive prostheses after 4 months.

Materials And Methods: Forty partially edentulous patients treated with one to three dental implants, at least 8.5 mm long and 4.

Immediate occluding definitive partial fixed prosthesis versus non-occluding provisional restorations - 4-month post-loading results from a pragmatic multicenter randomised controlled trial.

Purpose: To compare the clinical outcome of dental implants restored with definitive occluding partial fixed prostheses within 1 week, after implant placement with immediate non-occluding provisional restorations, which were to be replaced by definitive prostheses after 4 months.

Materials And Methods: Fifty partially edentulous patients treated with one to three dental implants, at least 8.5 mm long and 4.
