EvOKare studies its solutions and methods starting with an analysis of the problems.
Current splinting techniques involve joining the stumps to the implant platforms and linking them together with a titanium bar, to create a rigid framework to which a temporary prosthetic, or even a final denture can be joined, which allows immediate loading.
However, in the case of end osseous dental implants, the splinting technique involves using intra oral welding, to join the titanium bars to the various stumps on the prosthetic framework.
This technique is not without some disadvantages, as positioning the titanium bars correctly inside the patient’s mouth and welding are strongly dependent on the operator’s skills, and can be hindered by the patient’s movements when opening and closing their mouth, moving their tongue or swallowing, as well as by the presence of blood and saliva in the oral cavity.
The splinting technique currently used also involves using titanium bars which are sold in the form of straight segments about 20 cm long with circular cross section and a diameter generally measuring between 1 and 2 millimetres. The operator manually bends these titanium bars outside of the mouth, so they adopt a shape that reflects the actual arch layout of the implant platforms. However, this manual shaping is always only approximate as far as positioning the various titanium stumps on the implant platform is concerned.
Another drawback with current splinting techniques is that if the titanium bar and the titanium stump to which the bar is going to be welded don’t form a tight fit, the welding between the two parts will fail, and the two copper electrodes used in an intra oral welding machine will produce a flame, which is quite an unpleasant experience for the patient. In such cases, the welding process has to be repeated.
At the present time, the method described above means a dental practitioner has to use intra oral welding.
