Abstract
The present invention provides two-material upper jaw base-supported false teeth, and a making method thereof. A base support of the false teeth is composed of white alloy plates with the thickness of 0.2mm and plastic layers with the thickness of 0.1 to 0.3mm. The grinding teeth comprise the white alloy plates so that the abrasion resistance and the capability of crushing food are enhanced. When the false teeth are used by patients, the false teeth have the advantages of small foreign body sensation, clear pronunciation, and thin and firm base support without crack. The false teeth are suitable for whole mouth false teeth and upper jaw half mouth false teeth, and the grinding teeth containing the white alloy plates are suitable for patients without grinding teeth. Although the cost of the false teeth is increased a little, the repair rate is low, the service life is long, and the patients are satisfactory.
Description
The present invention relates to a kind of structure and method for making thereof of two-material upper jaw base-supportod false teeth.It belongs to the dentistry field.
The traditional method that tumbles in jaw half complete denture be impression taking, perfusion model, on
Frame, make cured mould, row's tooth, dress box, remove cured, dress glue, heat treatment, polishing.Its advantage is that technology is simple, easily manufactures; Weak point is, with the plastics upper jaw half complete denture that this method is manufactured, base is thick, and the patient uses the oral cavity sensation of fullness big, and not freely, it is tasteless to take food, and it is influenced to pronounce; Thin excessively as base, then easily break.In addition, the plastics artificial tooth wears no resistance, and is easily flat blunt, influences patient's diet.
Task of the present invention provide a kind of patient use foreign body sensation little, pronounce distinctly, base is thin and big maxillary denture and the method for making thereof of intensity, the easy broken food and wear-resisting of grinding one's teeth in sleep.
Task of the present invention is finished with the following method: the maxillary denture base is made up of the sheet metal of compression moulding and plastic layer placed on it and is combined into one, and the sheet metal surface is shaped on ripple, is beneficial to pronunciation and tongue stirring food.Contain lamellule in grinding one's teeth in sleep, so not only wear-resisting but also easy broken food.The concrete method for making of this artificial tooth is such, behind the impression taking, pours into two plaster models, on one
Frame, another makes mold, in order to the mould of casting pressed metal sheet.Its casting process is, get a plaster model, cavity is downward, places in the nowel that is placed on the flat board, use sand molding, nowel is made the back upset and is made top box for 180 °, and type is made the back and unpacked, and model drops in the nowel, before molding, be cast in melt metal in the cavity of plaster model, take out the cooling back, promptly is the patrix of mould; The melt metal moulding by casting is used in mould assembling after the molding, promptly is the counterdie of mould.The sheet metal of getting ready is placed between the upper and lower mould, use forcing press compression moulding.The peripheral size of sheet metal is less than the outside of alveolar ridge, the inflection 3-5mm of limit portion that is embedded in incisor dens supporter place becomes double-deck, to gain in strength, the opening of six to eight 3-5mm is evenly cut by the limit portion that is embedded in the dens supporter place of grinding one's teeth in sleep, and break engrail off with the fingers and thumb, with the adhesion of increase with plastics, towards even punching out ripple, stricture of vagina is deeply less than 0.2mm with flat on the surface.After sheet metal makes, promptly carry out traditional on
Frame, make cured mould, the cured thick 0.3-0.5mm of base portion.Arrange tooth, dress box then, remove cured, dress glue.Before dress glue, take out and all grind one's teeth in sleep, be coated with separating medium (as sodium alginate), with plastics (as methymethacrylate) the filling teeth cavity of the suitable patient's tooth form color and luster that modulates, and along each axis adding lamellule of grinding one's teeth in sleep, the dens supporter part will be stopped up with plastics then successively with to chew face concordant in the lower end, and the sheet metal of molding is installed, add the thick plastic layer of 0.1-0.3mm on sheet metal top, use forcing press compression moulding after installing glue, heat treatment, polishing.This artificial tooth is applicable to complete denture, the upper jaw half complete denture, contains grinding one's teeth in sleep of lamellule and is applicable to any molar deletion person.
The patient uses two-material upper jaw base-supportod false teeth, and foreign body sensation is little, and conduction cooling heat is fast, pronounces distinctly, and tongue range of activity in the oral cavity is big and flexible.This basal seat area is thin and firm, does not break, and contains the wear-resisting and easy broken food of grinding one's teeth in sleep of lamellule.With the artificial tooth that this method is manufactured, though cost increases to some extent, repair rate is low, long service life, and the patient uses satisfaction.
Below in conjunction with accompanying drawing the present invention is described further:
Accompanying drawing 1 is the longitudinal profile sketch map of two-material upper jaw base-supportod false teeth.
Accompanying drawing 2 is horizontal section sketch maps of two-material upper jaw base-supportod false teeth.
Accompanying drawing 3 is inverted two-material upper jaw base-supportod false teeth sketch maps.
With reference to accompanying drawing 1, the upper jaw half complete denture, its base is made up of sheet metal 1 and plastic layer 2, and sheet metal 1 becomes bilayer 5 at the dens supporter 4 places inflection 3-5mm of incisor 3, and double-deck length is between 20-30mm.
With reference to accompanying drawing 2, sheet metal 1 is evenly cut six to eight openings in 6 the dens supporter 4 place limit portion of grinding one's teeth in sleep, and breaks engrail 7 off with the fingers and thumb, and lamellule 8 adds along 6 the axis of grinding one's teeth in sleep, and lower end 11 is with to chew face 10 concordant.
With reference to accompanying drawing 3, evenly the ripple 9 of punching out is distributed on the surface of sheet metal 1.
Artificial tooth provided by the present invention, its base preferably adopt thick white alloy plate of 0.2mm and the thick plastic layer of 0.25mm because so both non-corrosives, again can be well and the palate tissue fit, and conduction cooling heat is fast.Lamellule in grinding one's teeth in sleep can in addition, contain the system of can giving in batch of grinding one's teeth in sleep of little white alloy plate with the tailing of the thick white alloy plate of the 0.2mm that manufactures base.The molding sand of said casting mould is modulated into 1/3 natural sand and 2/3 Gypsum Fibrosum, and the motlten metal of said casting patrix is molten stannum, and the motlten metal of casting counterdie is molten aluminum.Do not add lamellule in the incisor and be attractive in appearance for artificial tooth, do not influence the service life of artificial tooth like this.
