i) placing the copied refractory material abutment into water, and applying porcelain on the surface of the abutment on the neck edge line when the water absorption reaches a saturated state; after porcelain application, carrying out high-temperature treatment on the copied refractory material abutment to form a porcelain veneer;
j) and (3) grinding the part of the copied refractory material abutment which is subjected to high-temperature treatment and is far away from the porcelain facing, further carrying out sand blasting on the residual part of the copied refractory material abutment on the porcelain facing to remove the residual part of the copied refractory material abutment so as to only leave the porcelain facing, and finally attaching the sand-blasted porcelain facing to the upper part of the copied gypsum material abutment.
Furthermore, the artificial gum is driven into the reproduction gypsum abutment by 5mm-1cm, the artificial gum is used for the gum, the connection of red aesthetic and white aesthetic is observed, and the reproduction process of the refractory abutment and the porcelain facing is operated on a vibrator.
Further, the neckline is made with a special high temperature pen, and the remainder of the partially replicated refractory abutment on the porcelain veneer is away from the nozzle of the blasting during the blasting.
The invention has the beneficial effects that: the porcelain veneer manufacturing method is characterized in that gypsum abutment teeth are copied, a colloid sleeve body is manufactured by taking the abutment teeth as a reference, a refractory material abutment tooth is manufactured by the colloid sleeve body, and a veneer is manufactured on the refractory material abutment tooth, so that the effect of accurately manufacturing the porcelain veneer is realized, the precision of the manufactured veneer is improved, the matching degree of the veneer and the teeth of a user is improved, and the comfort degree and the satisfaction degree of the user in use are improved.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
A method for manufacturing a porcelain facing comprises the following steps:
firstly, checking whether an abutment model has a problem, wherein the abutment model comprises an upper part and a root part, and trimming the root part of the abutment model into the same shape as the root part of the abutment model, so that a gypsum abutment which is convenient to copy is driven into an artificial gum; then, turning a plaster abutment, finishing the root of the plaster abutment to form the same shape as the root of the abutment model, and finishing the attractiveness of the plaster abutment; placing the copied plaster abutment into a tray, and coating high-oil vaseline on the surface of the copied plaster abutment for separating the rubber sleeve body and the rubber sleeve body after the rubber sleeve body is manufactured; the root of the copied plaster abutment is driven into the artificial gum, and the artificial gum is positioned in the oral cavity model according to the real depth of the real tooth in the oral cavity of the user and is used for determining the position of an actual neckline so as to determine the size of the veneer to be manufactured;
then pour into the gypsum in the oral cavity model, extract the gypsum material abutment of reproduction after the gypsum solidifies, form the model recess the same with the gypsum material abutment of reproduction in the gypsum model, do pleasing to the eye finishing to the gypsum model: further fixing the copied plaster abutment in the center of the box by using wax for preventing the copied plaster abutment from deforming, pouring special glue which is uniformly stirred in proportion into the box, wrapping the upper part of the plaster abutment by the special glue, and forming a colloid sleeve body after solidification for serving as a mold for copying the refractory abutment; starting to copy the refractory abutment: after the colloid sleeve body is solidified, separating the copied gypsum-made abutment from the colloid sleeve body, and then pouring a refractory material into the colloid sleeve body; taking out the refractory material after solidification, performing high-temperature treatment for shaping the refractory material abutment, comparing the copied refractory material abutment with the copied gypsum abutment after shaping to ensure that the shapes of the two are completely consistent, then arranging a neck edge line on the copied refractory material abutment for determining the position and size of a veneering, and only applying porcelain on the surface of the refractory material abutment above the neck edge line for manufacturing a porcelain veneering;
starting a porcelain applying process: putting the copied refractory material abutment into water to prevent the refractory material abutment from absorbing water on the ceramic, and applying the ceramic on the surface on the neck edge line when the water absorption reaches a saturated state; after porcelain application, performing high-temperature treatment on the copied refractory material abutment to form a porcelain facing, and shaping the facing formed after porcelain application;
taking a veneering: and grinding the part of the copied refractory material abutment which is subjected to high-temperature treatment and is far away from the porcelain facing, further carrying out residual sand blasting on the rest part of the copied refractory material abutment on the porcelain facing to remove the part of the copied refractory material abutment and only leave the porcelain facing, and finally attaching the porcelain facing subjected to sand blasting to the upper part of the copied gypsum material abutment for detecting the accuracy of the attaching degree, the size and the like of the facing.
The artificial gum is squeezed into to reproduction gypsum material abutment 5mm-1cm for it is the same with the degree of depth that real tooth is located real gum to ensure that reproduction gypsum material abutment squeezes into artificial gum, in order to reach best simulation effect, artificial gum is used to the gum, observes linking of red aesthetic white aesthetic, the reproduction in-process of refractory material abutment and porcelain wainscot will be operated on the shock machine, prevents to have the steam pocket to influence the precision.
The neck flange line is made of a special high-temperature pen, and the residue of the refractory material abutment copied by the rest part of the porcelain veneering is far away from a nozzle for sand blasting in the sand blasting process and is used for preventing the veneering from being damaged in the sand blasting process.
The above examples are intended to further illustrate the present invention, but are not intended to limit the invention to these specific embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be understood to be within the protection scope of the present invention.
