Auxiliary tool for fixing and repairing teeth and use method

Abstract

The invention discloses an auxiliary tool for fixing and repairing teeth and a use method, the auxiliary tool comprises a dental handpiece and a guide plate, the dental handpiece comprises a handle and a machine needle arranged on the handle, one end of the handle is provided with a handpiece, the handpiece is provided with a plurality of positioning points, and the machine needle is located among the plurality of positioning points; the guide plate comprises a plate body, a notch formed in the plate body and a plurality of guide rails located on the periphery of the notch. According to the auxiliary tool for fixing and repairing the teeth and the use method, through an accurate guide rail control mode, a common positioning path is closer to be parallel, the friction force between the false tooth and the abutment is increased, the condition that the fixed false tooth is easy to fall off is effectively avoided, and for preparation of the abutment, a shoulder can be clearer, uniform in thickness and consistent in height; meanwhile, through the cooperation of the guide plate and the dental implanter, the dental implant operation can be completed, and the dental implant is better in applicability.

Description

technical field [0001] The invention relates to the technical field of fixed tooth restoration, in particular to an auxiliary tool for fixed tooth restoration and a method of use thereof. Background technique [0002] The method of fixed tooth restoration is usually to prepare the tooth first, and then make and install the denture. When preparing the tooth, the dentist first uses a dental handpiece to polish and trim the tooth. After the trim is completed, the patient takes an impression and makes a corresponding temporary tooth. , and send the produced model to the denture processing factory, and then after at least several days to complete the production of the denture, and then install the denture. The dental handpiece is a handle with a round handle, and a bur is installed for grinding and trimming the teeth. However, when dentists use dental handpieces to perform actual operations on patients, there are some problems: [0003] One is that during tooth preparation, the...

AI Technical Summary

Problems solved by technology

[0003] One is that during tooth preparation, the use of dental handpieces to grind and trim teeth is entirely dependent on the experience and feel of the dentist. The position of the restoration shoulder of the full crown is variable, and the shape is often blurred or has no shoulder or different shoulders. The position width is uneven, and there are too many limiting factors in the tooth grinding process, such as the doctor's finger strength, wrist strength, arm strength, emotion, fatigue and experience, etc. will interfere with the grinding of the teeth in the patient's mouth, which will affect the health of the patient's teeth. and the service life of the denture, and remove the above unstable factors, there is an inevitable problem of direct manual operation: the parallelism of the common seating path

If more than one abutment is prepared, it is necessary to have a good common positioning path in the preparation process to ensure that the future denture can be in place and tight. If two (or more) abutment teeth are inconsistent, it will make it difficult to fit the denture. In place or not in place, usually in order to make the dentures of multiple abutment teeth in place, the stomatologist often prepares the abutment teeth into a conical shape to achieve the purpose of co-positioning. Excessive wear and tear, but there is no solution at present, and the too inclined abutment teeth will lead to insufficient friction between the fixed denture and the abutment teeth after installation, which will easily cause the fixed denture to fall off, and the bridge body with multiple abutments , once a part of the abutment loosens, it will cause the internal abutment to be corroded and rotted by bacteria, resulting in irreparable consequences;

[0004] The second is that the abutment teeth are polished and trimmed first, and the dentures are made later, and it takes a long time to send the model to the processing factory and receive the model. During this period, the teeth have been polished and become sensitive. It is easy to cause great tooth sensitivity pain and mood swings to the patient, and because the temporary teeth are easy to fall off repeatedly, the process of repeated removal and wearing of the temporary teeth requires repeated drying, which further aggravates the discomfort of the patient;

[0005] The third is that temporary teeth need to be installed in the process from tooth preparation to denture installation, and dentists are required to make temporary teeth for patients. The making and repair of temporary teeth need to consume a lot of time for doctors and patients. Making temporary teeth makes dentists and patients The chair time is greatly prolonged, which reduces the efficiency of dental fixed restoration
