Description

Removable friction fixed artificial tooth

Technical Field

The invention relates to a method for manufacturing a false tooth, in particular to a method for manufacturing a plurality of or whole movable false teeth, and particularly relates to a method for manufacturing a removable friction fixed false tooth.

Background

In dentistry, the success rate and popularity of artificial tooth implantation are the first choice for the medical field to restore the function of the edentulous area of a patient, and for the formation of the artificial tooth implantation process, an artificial tooth root is screwed into the alveolar bone of the oral cavity, and an artificial tooth crown is fixed at the upper end of the artificial tooth root exposed out of the dental pulp, so that the function of the tooth is restored, and the artificial tooth implantation is expected to be used permanently. In the above-mentioned artificial tooth implantation method, the artificial tooth root comprises an implant body screwed into the alveolar bone of the tooth, and a support is locked to the implant body so that the support is exposed outside the gum, after a period of bone fusion, the implant body, the support and the gum bone are integrated to form a support post, and then an artificial tooth impression and a tooth crown are made, and finally the artificial tooth crown is fitted on the support, thereby restoring the function of the tooth. In addition to the establishment of the vertical depth and the occlusal plane, the bearing relationship of different occlusal forces must be considered when manufacturing the false teeth, so that all teeth are stressed in balance when in occlusal contact, and the factors are inseparable from the manufacture of the false teeth. Moreover, the conventional tooth implantation method needs to implant the implant body one by one on the affected part, i.e. one artificial tooth corresponds to one artificial implant body, if a patient needs to implant a plurality of teeth or even rebuild the whole mouth, the treatment process is quite long and complicated, the cost is very high, and especially, if the local tooth bone quantity of the oral cavity of the patient is insufficient, the tooth implantation is easy to fail. In addition, it takes a lot of time to make the denture impression and the dental crown, and the denture after impression is not sufficiently close due to the hyperplasia of gum, which causes the defect of the denture in use.

referring to fig. 2, the implant procedure 10 is to plan the implant site and the number of implants by studying the shape of the patient's mouth and teeth, and after the implant procedure 10 is completed, a predetermined number of artificial implants 11 are implanted into the patient's alveolar bone, and each artificial implant 11 has an abutment 12 extending therefrom, and each abutment 12 is protruded out of the gum surface. In addition, the abutment 12 protruding beyond the gingival surface can be nested with a sleeve cover 13 of suitable size to avoid gingival hyperplasia that could affect the angle and position of the abutment 12.

Referring to fig. 3 to 5, in the first stamping step 20, a sleeve 21 with a size suitable for the support 12 is selected, a support rod 212 is welded on a main rod 211 of the sleeve 21 in a transverse direction (as shown in fig. 3), each sleeve 21 is sleeved on the corresponding support 12 (the sleeve cover 13 is removed), the stamping material is injected on the surface of each sleeve 21 and completely coated, a stamping plate is pressed on the stamping material, and after the stamping material is hardened for 3 to 5 minutes, a model formed by the stamping material is removed, so that the first stamping step 20 is completed. By means of the first impression step 20, a model of the precise angle and corresponding position of each abutment 12 in the implant step 10 can be obtained (see fig. 4 and 5).

The step 30 of fabricating the artificial gum is to take the same support 12 as the step 10 of fabricating the implant as the artificial implant 31, lock and fix an extension rod 311 on the artificial implant 31, stick a support rod 312 transversely to the extension rod 311 (as shown in fig. 6), sleeve each artificial implant 31 into the sleeve 21 belonging to the first impression step 20, coat a separating agent on the surface of the model to facilitate subsequent demoulding, then inject the artificial gum on the surface of each artificial implant 31 to completely coat the artificial gum (without the extension rod 311 and the support rod 312), and remove the artificial gum after drying to obtain a gum model 32, thereby completing the step 30 of fabricating the artificial gum (as shown in fig. 7 and fig. 8).

Referring to fig. 9 and 10, in the second impression step 40, a sleeve cap 41 with a size suitable for the support 12 is inserted into the support 12 protruding out of the gum surface, the first silicone occlusion material is pinched into a long strip shape to press the gum of the affected part, the upper and lower jaws are engaged, after 2 to 3 minutes, the silicone occlusion material is hardened and then taken out, so as to obtain a stable occlusion relation model 42 (including the shape of the gum of the affected part, the support 12 and the occlusion position of the engaged teeth).

Referring to fig. 11, in the metal frame manufacturing step 50, the patient's upper jaw model 51 and lower jaw model 52 are matched with the gum model 32 obtained in the gum simulating step 30 and the occlusion relation model 42 obtained in the second impression step 40, and are set in the occlusion machine to obtain a bending curve of the metal frame, and then the metal frame and the sleeve are welded by resistance spot welding to obtain the metal framework 53 (as shown in fig. 12). After the metal framework 53 is completed, the sleeve of the metal framework 53 can be placed on the upper jaw model 51 (affected part) containing the gum model, then the second silicone occlusion material is injected on the metal framework 53, the lower jaw model 52 (opposite to the teeth to be bitten) corresponds to the upper jaw model 51 before the second silicone occlusion material is dried, and the occlusion foundation of the metal framework 53 is obtained after the second silicone occlusion material is dried.

The artificial tooth manufacturing step 60 is to set the angle of the metal framework 53, then to make the artificial tooth impression and the artificial tooth crown by using the metal framework 53 as the support, the artificial tooth crown is made by combining the composite resin material with the sleeve and the metal framework to form the artificial tooth 61, the artificial tooth crown makes up the missing tooth of the affected area of the patient, the whole artificial tooth covers the sleeve and the metal framework 53, the sleeve opening is exposed from the end face of the artificial tooth 61, the sleeve opening can be sleeved on the support 12 of the artificial implant, so that the artificial tooth crown and the missing tooth of all the missing tooth areas of the affected area are satisfied, and the sleeve and the support 12 are fixed due to the combination relationship of the two, as shown in fig. 13.

The false tooth obtained by the method of the invention obtains a metal framework with accurate size through the first impression step 20, the step 30 of manufacturing the imitated gum and the second impression step 40, then the gum and the crown are manufactured on the metal framework to form the false tooth, and finally each sleeve is sleeved on the support to complete the tooth implantation treatment, therefore, the method can accurately position the size, the angle and the support.
