METHOD OF IMPRINT PRODUCTION IN PROSTHETICS ON IMPLANTS AND TEETH Russian patent published in 2016 - IPC A61C9/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to orthopaedic dentistry, and is applicable in orthopaedic treatment of patients with partial toothlessness. Making impression for making impression dental crown (for example, from composite (Protemp 4), plastic) with S-silicone base layer (for example, Speedex), with A-silicone (for example, Elite HD, Express) or polyester (for example, Impregum). Performing preliminary odonto-preparation under impression dental crown. Dental impression crown is made, on which retentional points are made in form of longitudinal and transverse grooves and perforation opening in grinding surface or by cutting edge. Impression dental crown is fitted on tooth stump. Performing final odonto-preparation for creating space for corrective material piece, ceramic or metal-free structure. Install transfers for impression using closed or open tray technique. Adhesive is applied (for example, Bisico Adhesive) on entire surface of impression dental crown. In impression dental crown correcting material is introduced (for example, Elite HD), and it is positioned on tooth stump. Impression is made with two-phase or monophase impression material. In prepared imprint impression dental crown remains in cast material mass.

EFFECT: due to absence of lines and pores on surface of tooth stump, larger depth of penetration of impression material in subgingival space, method allows to produce high-precision display of prosthetic bed.
