Quattro AV attachment w. acrylic matrix, with acrylic matrix
Description
With this attachment you can adjust the level of friction completely individually on the activation screw. Greater height gives you very good guidance.
Precision attachment for universal use in the intra-, inter- and extracoronal area. High level of comfort due to screw fixing of the patrix to the model cast. The patrix guide is an integrated part of the model cast, which removes the need for any soldering work.
Transfer of the initial position to the investment material can take place either with reversible duplicating material and use of the original patrix, or by processing special duplication patrix in conjunction with silicone duplication.
As it does not have to be soldered to the attachment fixing, potential causes of error are eliminated, and quicker, unproblematic exchange of the patrix is guaranteed - any exchange can be made in no time.
By means of targeted use of the adjusting screw, the wings on the patrix can be spread open in a controlled manner, which permits effective and individual control of the amount of friction in the area of the attachment.
