Detailed Description

The technical scheme described in the application is further described and illustrated below with reference to examples.

Example 1: a caries treatment tool comprises a grinding head 6, wherein the top of the grinding head 6 is fixed with an ultrasonic transducer 5, the ultrasonic transducer 5 provides a vibration power source for the grinding head 6, and the grinding head 6 is

In the model structure, the surface of the grinding head 6 contacted with the tooth 1 is a silicon carbide surface 61, and the rest non-contact surfaces are smooth surfaces 62; the size of the middle area 7 of the grinding head 6 is smaller than that of the front end and the rear end of the grinding head 6, and clamping grooves are formed in the position of the middle area 7.

Example 2: an inlay for use with a dental caries treatment tool, wherein the inlay 4 is

The inlay 4 is of the same size as the grinding head 6 or of the same upper tolerance as the grinding head 6.

Example 3: a method of treating dental caries using a caries treatment tool and inlay, wherein the method includes the steps of:

firstly, determining the occurrence area of decayed teeth 2 and the damage range of teeth, and selecting a grinding head 6 with a proper size and model;

secondly, ultrasonic grinding is carried out on the decayed tooth region by adopting a grinding head 6 containing an ultrasonic transducer 5, and the tooth 1 is ground by utilizing a diamond surface 61 of the contact surface of the grinding head 6 and the tooth 1;

thirdly, after the upper surface of the grinding head 6 is flush with the surface of the tooth 1, finishing grinding, taking out the grinding head 6, and adhering the inlay 4 with the corresponding model into the groove formed by the tooth 1;

fourthly, the inlay 4 after the gluing is partially decorated, so that the inlay is matched with the teeth 1 to meet the aesthetic requirement.

In view of the above embodiments, the working process and principle of the present application when in use are as follows:

the invention actually provides a method and a tool for simplifying the dental caries restoration process, which aim to avoid the problems of time and cost waste caused by model making and inlay customizing in the original dental caries restoration, and the customized inlay is not necessarily firmly combined with teeth due to the existence of measurement errors, so that the movement and even falling easily occur.

The invention adopts that

The grinding head 6 of the mould structure, the grinding head 6 comprising a diamond face 61 and a smooth face 62, is shown in figure 1. The two faces pointed by the arrows in fig. 1 are non-contact faces with the teeth 1, which are smooth faces 62. The rest is that the teeth 1 need to be contacted in the grinding process, vibration is realized through the ultrasonic transducer 5, and the teeth 1 are ground through silicon carbide, so that grooves suitable for the requirements of the inlay 4 are ground.

Inlay 4 is shaped to accommodate grinding head 6, as

The structure comprises a longitudinal elevation 41 and a transverse elevation 42, and the outer surface of the longitudinal elevation 41 and the upper surface of the transverse elevation 42 are smooth surfaces corresponding to the grinding head 6. The rest is contacted with the tooth 1 and is adhered in the groove formed by the grinding head 6 through medical glue. Inlay in cooperation with grinding head 6 has the advantage of optimizing the patient's visit, reducing patient round trip time and clinical time, and ensuring inlay 4 and teethThe degree of the jogging of the repairing area 3 on the tooth 1 achieves the aim of zero movement. Ideally, the size of the grinding head 6 is the same as the size of the inlay 4, enabling the inlay 4 to be directly embedded after grinding, ensuring that the inlay 4 is not movable within the tooth 1. However, in practical use, since there is an error in the dimensions of the grinding head 6 and the inlay 4, in order to ensure that the inlay 4 fits tightly with the recess formed in the grinding head 6, the dimensions of the inlay 4 should in principle be such that they are within the upper tolerance of the grinding head 6, such that they achieve a transition fit or an interference fit.

According to the above procedure, the doctor only needs to confirm the occurrence range of the dental caries 2 on the tooth 1, confirm the size of the required restoration area 3, then select the grinding head 6 with proper size and model, and the grinding head 6 generates energy by utilizing ultrasonic vibration under the drive of the ultrasonic transducer 5, and grinds the tooth 1 through the silicon carbide surface 61. The shape of the ground groove is the same as that of the grinding head 6, so that the inlay 4 matched with the grinding head can be filled to finish the repairing operation. The method is convenient and fast, reduces the clinical modeling and custom processing links of the original teeth for medical treatment, saves time and cost, and improves the efficiency of the treatment.
