Application of optical scanning systems and 3D modeling algorithms as a method to control the depth of teeth preparation for fixed orthopedic structures

Background. In orthopedic dentistry at the present stage of its development, a chemical technique for preparing teeth fixed structures dentures has been developed; however, state pulp in response to preparation is not taken into account. As result, medical tactics preserving or extirpating abutment teeth, depending on clinical case, are unreasonable. Given generally accepted rules structures, there significant percentage complications. Controlling depth tooth makes it possible carry out this manipulation as rationally possible, and result ensure effectiveness procedure, based vitality prepared teeth. The aim study determine control studied using digital volumetric scanning technology algorithms graphic 3D editor CAD/CAM system. Materials methods. article presents results system an integrated algorithm modeling structures. Results. Based scanning, working thickness area neck was determined with formation various types chamfer different groups. order hard dental tissues, artificial crown modeled CAD — scanner NeWay (Open Technologies) data ledge were obtained. Conclusions. Method tissues prevent development irreversible morpho-functional changes caused by odontoreparation.
