Method for manufacture of reinforced basis of removable prosthesis

FIELD: medicine.

SUBSTANCE: after obtaining of anatomical impressions from both jaws of the patient, the stage of central occlusion determination and models plugging into the occludator/articulator, artificial teeth setting is begun, taking into account the anthropometric indices. The wax structure of the prosthesis in the patient's oral cavity is checked. The wax is replaced by thermoplastic according to the manufacturer's instructions. At that, the basis of the removable prosthesis is reinforced, adding up to 1 wt % of nanostructured titanium dioxide in the form of a powder directly to the polyamide granules, evenly mixing it in the thermoplastic mass. The basis is made of polyamide structural material Vertex ThermoSens.

EFFECT: method allows to increase the effectiveness of orthopedic treatment with removable dentures due to improved strength and aesthetic characteristics, absence of residual monomer in the prosthesis basis construction material.

FIELD: medicine.

SUBSTANCE: invention refers to medicine, specifically dentistry, and is applicable for prosthodontic treatment. A rigid base of the dental arch comprises an elongated rigid member cambering after the dental arch. A front site of the elongated member goes into its back site nearby the canine teeth. The back site is flatter and more horizontal at the sites between the first and second molars.

EFFECT: reducing time expenditures for making the prosthetic dentures, improving the quality and the method for making them.

FIELD: orthopedic stomatology.

SUBSTANCE: method of forming elastic silicone substrate on rigid plastic basis consists in that mechanically and chemically treated surface of rigid basis adjusting to prosthetic bed is moistened with monomer being a member of basis plastic composition, dried, and coated with adhesive primer. After 1 min pause, basis is introduced for 3-4 min into microwave field emitted by source with power 450-600 W. After microwave treatment, surface is coated by cold-cured elastomer and substrate layer is then formed in mouth cavity. Adhesive strength of layer is thus increased by more than 1.5-2 times when compared to conventional method.

EFFECT: increased strength of bond between soft substrate and rigid plastic basis, and prolonged service time of denture.
