Treatment guide plate for root canal treatment and preparation method thereof

The invention discloses a treatment guide plate for root canal treatment. The treatment guide plate comprises a closing plate, and the closing plate comprises a matching surface matched with a tooth crown shape of a part of teeth or all teeth of an affected tooth or an affected tooth and an adjacent single tooth. Guide holes corresponding to corresponding root canals are formed in the closing plate, one end of each guide hole is located in the matching surface, the position design of the guide holes depends on the three-dimensional stress finite element analysis of the teeth, and a mechanical strut region of the teeth is avoided; when a drill pin penetrates through the corresponding guide hole to drill a marrow hole of the affected tooth, the mechanical strut structure of the affected tooth cannot be damaged by the drill pin, and the anti-stress structure of the tooth is protected; the teeth are prevented from being cracked when biting hard objects after operations. The invention further provides a preparation method. The preparation method of the treatment guide plate for root canal treatment is simple, mature and easy to popularize, and the prepared treatment guide plate effectively avoids damage to the mechanical strut structure of the affected tooth, so that the teeth can be prevented from being cracked when biting the hard objects after the operations.
