A method of manufacturing a laminar dentures
(57) Abstract:The invention relates to medicine, namely to prosthetic dentistry. The technical result - the reduction of the period of adaptation to the removable laminar dentures. The method is carried out by making removable laminar dentures with fenestrated basis. After receiving anatomical prints and manufacture of rigid individual spoons in the anterior hard palate using indelible pencil outline of the transverse folds, impose strict individual spoon for footprint, the boundaries of which do fenestrated hole using fissure boron. Next get a functional impression, determine the Central value of the jaws with wax bases with occlusal rollers, check its correctness, a pin is stuck and put the prosthesis on the upper and lower jaw. 1 Il. The invention relates to medicine, namely to prosthodontics.Currently manufactured full dentures for the upper jaw, the base of which covers all of the hard palate, in some cases, making their use difficult patients because of an thoseare teeth. - M.: Medicine, 1990, S. 174-188).Adaptation to full removable laminar dentures is delayed up to 30 days, and sometimes does not occur at all, and patients refuse to use artificial limbs, despite the sharp disruption of the mouth (chewing, foncia and so on).One of the analogues we offer laminar prostheses with fenestrated basis are prostheses with reproduced on the surface of the base facing toward the language, the architectonics of the hard palate, proposed by J. C. Platicar (Dental Herald, 1905 , No. 10, S. 718) and repeated A. Lange (Soviet dentistry, 1932, No. 1, S. 12).However, the application of the above methods do not always provide the desired result.J. C. Plotecher and A. Lange, offering to play on the lingual surface of the base of the denture in the upper jaw transverse Palatine folds, do not take into account that the plastic base is not as helpless as the mucous membrane of the hard palate and, therefore, is perceived as a foreign body.The closest in technical essence to the proposed method is a method of manufacturing a plate dentures for the upper jaw, including the manufacture of laminar basis with konceptsii to removable laminar dentures.The goal is the fabrication of removable laminar dentures with fenestrated basis.The method is as follows: after receiving anatomical prints using alginate mass Deguprint and manufacture of rigid individual spoons spend their fitting with the use of functional assays Herbst. Then solid sky with indelible pencil outline the transverse crease of the hard palate, impose strict individual spoon to get the printout, on the borders of which further conducts the removal of the basis of the individual spoons window using corrective Lastic mass Xtra using functional assays Herbst. Determine the Central value of the jaws with wax bases with occlusal rollers. Check the wax design dentures and correctness of definition of centric relation. A pin is stuck and put the prosthesis on the upper and lower jaws (see drawing). On the basis 1 of the prosthesis in the anterior hard palate has fenestrated hole 2, which leaves free the transverse folds of the hard palate. Plastic teeth 3 of the upper dentition placed in orthognatic zootoxin the teeth of the upper jaw (type 2 atrophy by Schroeder), complete loss of teeth in the lower jaw (2 a type of Courland). The patient was strongly pronounced gag reflex.The patient had made a full removable dentures on the upper and lower jaw, and on the top was made 2 of the prosthesis: one by the traditional method and the other with fenestrated basis.First, within 30 days, the patient was asked to use a prosthesis made according to traditional methods. Complaints of the patient were mainly confined to the emergence of a gag reflex, loss of appetite, disturbance of taste and tactile sensitivity, although the boundaries of the prosthesis corresponds to the norm. After 30 days of adaptation to the prosthesis has not occurred, and the patient was superimposed prosthesis with fenestrated basis. During the correction, the next day, the patient reported that she is more convenient to use the prosthesis. Hardly been gagging, no changes from gustatory and tactile sensitivity. After 3 days the patient argued that the discomfort associated with the use of prostheses, disappeared completely. After 30 days was conducted by visual inspection, which showed that the patient uses the prosthesis with fenestrated basis, do not feel of their oral cavity adaptation to dentures.The use of this design of the prosthesis, along with the satisfactory restoration of the functions of mastication, promotes rapid adaptation to the prosthesis does not violate the gustatory and tactile sensations, contributes to maintaining the clarity of pronunciation hissing sounds, shown in prosthetics patients with increased gag reflex at 1 and 2 type toothless upper jaw according to Schroeder. A method of manufacturing a removable plate dentures for the upper jaw, including the manufacture of laminar basis with fenestrated hole, characterized in that after receiving anatomical prints and manufacture of rigid individual spoons, in the anterior hard palate chemical pencil outline of the transverse folds, impose strict individual spoon for footprint, the boundaries of which do fenestrated hole fissure boron and receive functional impression, then determine the Central value of the jaws with wax bases with occlusal rollers, check its correctness, a pin is stuck and impose the prosthesis.
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.

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.

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.
SUBSTANCE: method involves using obturating prosthesis having basic and auxiliary surface connected to each other with additional anterior, posterior and two lateral vertically arranged surfaces forming a cavity. The anterior and posterior vertically arranged surfaces have slot-like recesses. Reference notch marks are produced on the auxiliary surface near nose. The alveolar process is manufactured as base and wall. Reference notch marks are produced on the base. Wall has holes for making process lightweight. Teeth are set on the wall.
EFFECT: simplified prosthesis design.
