Temporary tooth prefabricating method

Abstract

The invention relates to a temporary tooth prefabricating method. The method comprises the steps that S1, a doctor obtains three-dimensional image data of the oral cavity of a patient through intraoral scanning; S2, the doctor compresses data obtained by intraoral scanning and sends the compressed data to a manufacturer; S3, the manufacturer prints a virtual oral cavity model according to the intraoral scanning data; S4, temporary teeth are designed and manufactured according to the occlusion relation between the upper teeth and the lower teeth and the adjacent gingival form; S5, the temporaryteeth are worn in the virtual oral cavity model; S6, the temporary teeth are grinded and trimmed according to the gaps between the temporary teeth and the adjacent teeth, the occlusion relation between the upper teeth and the lower teeth and the gingival state; and S7, the adjusted temporary teeth are sent to a hospital. According to the method, by means of intraoral scanning and data transmission, time is saved, patient experience is optimized, and infection is not likely to happen; and meanwhile, the temporary teeth are subjected to simulation test, so that the patient wears more comfortably, the adaptability is higher, the step of debugging in the mouth of the patient for many times is avoided, and the preparation efficiency of the temporary teeth is improved.

Description

technical field [0001] The present application relates to the field of dental implants, in particular to a temporary tooth prefabrication method. Background technique [0002] Temporary teeth are temporary restorations that cannot be worn freely by the patient after the tooth preparation for the fixed restoration and before the final fixed restoration is completed. Temporary teeth mainly prevent the gums from growing to the shoulder, prevent the displacement of the abutment teeth during the crown production process, and at the same time restore the chewing function and pronunciation function. [0003] In the prior art, the preparation of temporary teeth includes 1. making a negative impression before tooth preparation; 2. injecting temporary crown and bridge resin into the prepared impression and waiting for the temporary crown and bridge resin to solidify; 3. When the bridge resin is in the elastic stage, put the primary cured temporary crown and bridge resin into the pati...
