Study that provides scientific evidence for the clinical advantages of the TRI Bone Adapt thread design.

Title
Stress distribution around TRI-Vent dental implants

Investigator/University
Prof. Lakatos
Budapest University of Technology and Economics, Department of Structural Mechanics

Aim
The effect of micro-grooves in the upper region of the implant, where it is connected to the cortical bone, was examined by comparing the behaviour of the bone around two implants, modelled with the same geometry (one with micro grooves and one with a smooth surface at the cortical bone region).

Study Protocol
Stress distribution around TRI Dental implants with micro-grooves were compared to implants without micro grooves around the top by means of CAD FEM analysis.

Conclusion
From the simulation results, it can be concluded, that – because of the relatively low and evenly distributed stresses in the cortical bone – the TRI Vent thread formation is advantageous in respect of the normal function of the healed implant, compared to those conventional screw implants without grooves in the crestal area.

Study that shows similar primary stability of TRI Vent 4.1 mm implants compared to TRI Vent 4.7 mm implants.

Presented at the 20th Annual Scientific Meeting of EAO 10-13 October 2012, Copenhagen, Denmark.

Aim
Measuring impact of implant diameters on primary stability in relation to three different bone densities in vitro (Soft, Medium, Hard).

Study Protocol
A total of 64 TRI dental implants were placed in fresh bovine bone samples. A loading device, consisting of a digital force gauge and a digital micrometer was used to measure the micromovements of the implant during the application of 25 N lateral forces.

Conclusion
Increasing implant diameter from 4,1 mm to 4,7 mm does not influence significantly the primary stability in any type of bone density.

Study that investigates the influence of implantoplasty (for treating peri-implantitis) on implant stability.

Aim
Implantoplasty, a procedure that is done to smooth contaminated implant surfaces, has been used in the treatment of peri-implantitis. It reduces the implant diameter, which might compromise the implant’s strength. This in vitro study was designed to evaluate the effect of implantoplasty on implant strength.

Study Protocol
32 TRI Vent implants have been used (half 3.7, half 4.7mm). The control group did not receive implantoplasy. The specimens were then loaded 30 degrees off-axis in a universal testing machine until fracture failure occurred.

Conclusion
Within the limits of this study, implantoplasty appeared to weaken the strength of narrower implants. Therefore, this procedure should be performed with caution on narrower, freestanding implants that are subject to greater occlusal force.

Advantages of TRI Octa implants with pink implant shoulder vs. tissue level implants with titanium-coloured neck.

Title
In vitro color changes of the soft tissues caused by a modified pink titanium surface compared to standard restorative materials

Clinic for Fixed and Removable Prosthodontics and Dental Material Science, University of Zurich, Switzerland

Aim
The aim of this study was to analyze the effect of modified pink titanium and other restorative materials on the color of mucosa of three different thicknesses.

Study Protocol
Plates of palatal pig gingiva with different thicknesses are harvested from 10 pig maxillae. Various disks of anodized and pure titanium are placed below the harvested gingiva and translucency is measured with a reflectance spectrophotometer .

Study Progress
Publication expected Q4 2014
