Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of dental preparation operation device, concretely to a dental preparation baffle convenient for operation. BACKGROUND

[0002] The whole process of wearing a full crown prosthesis in a dental operation can be roughly divided into the following steps: initial consultation and tooth preparation, color matching and model making, temporary crown making and wearing, crown making, crown trial wearing, crown cementing, follow-up care and review.

[0003] In the tooth preparation process, the patient needs to closely cooperate with the doctor's operation, and if the patient's tongue body swings and the buccal mucosa is not pulled open enough, it not only hinders the doctor's operation, but also easily grinds the patient's soft tissue. In addition, in the crown cementing step, because the full crown needs glass ionomer cement to be fixed, and this adhesive is soluble in water, it is necessary to strictly prevent moisture. The existing moisture-proof technology often uses rubber dam moisture-proof method and cotton roll moisture-proof method. The former places the rubber dam cloth and the rubber dam clamp together on the neck of the tooth that needs to be moisture-proofed during operation, which blocks the operation area at the neck edge of the full crown prosthesis and the abutment during cementing, thereby affecting the cementing of the prosthesis. In the moisture-proof process, the cotton roll is easily displaced by the movement of the tongue, thereby affecting the moisture-proof effect. For example, the patent with application number CN202320645255.8 discloses a rubber dam clamp that prevents leakage, including a rubber dam clamp body, a clamp placing through hole is longitudinally provided through the bottom of the rubber dam clamp body, a concave beak edge is provided on the inner side of the bottom of the rubber dam clamp body, a beak part clamping contact lining is fixedly installed on the concave beak edge of the inner side of the bottom of the rubber dam clamp body, and a tooth contact glue column is bonded to the inner wall of the beak part clamping contact lining. By setting the beak part clamping contact lining at the concave beak edge of the rubber dam clamp body and setting the tooth contact glue column on the beak part clamping contact lining, the beak part clamping contact lining contacts the tooth through the tooth contact glue column, the tooth contact glue column made of silicone rubber contacts the tooth, the elasticity and deformation effect are good, the contact clamping is more compact, thereby preventing leakage, improving the tightness of the rubber dam clamp and the tooth, achieving the effect of preventing leakage, preventing the medicine from leaking into the oral cavity during treatment, and avoiding the inconvenience of using a sealing agent. However, it still does not solve the problem of the rubber dam obstructing the cementing. SUMMARY

[0004] In view of the deficiencies in the prior art, the purpose of the present utility model is to provide a dental preparation baffle that facilitates operation, which can block the tongue, open the lips, and leave enough space for crown cementing, without affecting the cementing, and can also insert cotton rolls or medical cotton balls into the gap for effective moisture-proofing.

[0023] In order to make the technical means, creative features, purposes and effects achieved by the present application easy to understand, the present application will be further described below in conjunction with specific embodiments.

[0024] Referring to the accompanying drawings Figure 1 to Fig. Figure 5 , a tooth preparation baffle facilitating surgical operation is characterized in that it comprises a tooth preparation baffle body 1 and a clamping base 2, and the tooth preparation baffle body 1 is connected with the clamping base 2 through a connecting arm 3. The tongue is blocked and the lips are pried open through the tooth preparation baffle body 1, so as to facilitate the tooth preparation surgery.

[0025] The tooth preparation baffle body 1 comprises a first baffle 4 in contact with the tongue and a second baffle 5 in contact with the inner side of the lips, and the inner sides of the first baffle 4 and the second baffle 5 are each provided with a protruding upper connecting protrusion 6, the bottom of the upper connecting protrusion 6 is provided with an upwardly recessed first insertion slot 601, and the first insertion slot 601 is connected with one end of the connecting arm 3.

[0026] The clamping base 2 comprises a connecting arch 7 and a tooth side clamping wing 8, the connecting arch 7 is respectively connected with the top of the tooth side clamping wing 8 on the same side at both ends, the outer side of the tooth side clamping wing 8 is provided with a protruding lower connecting protrusion 9, the top of the lower connecting protrusion 9 is provided with a downwardly recessed second insertion slot 901, and the second insertion slot 901 is connected with the other end of the connecting arm 3.

[0027] In use, first hold the tooth side clamping wings 8, clamp the clamping base 2 on the tooth, and then select the specific fixed tooth according to the specific position and number of the full crown restoration tooth, generally select one tooth on the left and right of the full crown restoration tooth, then clamp the clamping base 2 on the tooth, select the appropriate size of the connecting arm 3 and the first baffle 4 and the second baffle 5, first complete the insertion of the connecting arm 3 with the first baffle 4 and the second baffle 5, and finally insert the tooth preparation baffle body 1, the combination of the connecting arm 3 and the clamping base 2. There is a gap between the first baffle 4 and the clamping base 2, and a gap between the second baffle 5 and the clamping base 2, a cotton roll or a medical cotton ball can be placed in the gap to keep the mouth dry, and the tongue is blocked by the first baffle 4 and the lips are stretched by the second baffle 5, which facilitates the tooth preparation operation.

[0028] The connecting arm 3 comprises a lower insertion part 301, a horizontal part 302 and an upper insertion part 303 connected in sequence, the lower insertion part 301 is connected with the second insertion slot 901, and the upper insertion part 303 is connected with the first insertion slot 601.
