The WINTRAY® Impression Tray was developed in cooperation with Dr. Guillaume and Dr. Mazeirat to enable taking an accurate impression of dental implants.
In implant prosthetics the prosthetic result depends directly on the reliability of the pick-up impression, which is required for fabricating the laboratory working model. Stock trays or custom trays made from resin materials do not meet the biomechanical requirements of implant restorations. In order to take pick-up impressions of dental implants for the dental laboratory, dentists must currently use a stock tray and drill some holes through it, therefore destroying the tray, or get a perforated custom tray fabricated in a dental laboratory at considerable costs.
The WINTRAY® Impression Tray was developed in a way that several segments can be removed at the position of the implant.
It is much easier and faster with the latest generation of WINTRAY®, as the segments are only retained using a simple retentive clip instead of a screw compared to our previous well-established model.
The low tray walls also allow closer proximity to the alveolar ridge to produce greater emergence of the impression posts, which is then more clearly visible intraorally. In addition, the shorter tray walls do not press as strongly on the mucosa and are therefore less painful for patients with edendulous jaws. Due to the fact that the windows are larger now the new WINTRAY® can be used of pick-up impressions with divergent axes, which is very useful in the case of superstructures on several abutments.
The WINTRAY® is an impression tray with removable segments – it is rigid, re-usable, can be sterilized and only a single appointment ist required for casting a perfect working model.
