Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a personalized passive constraint guide plate and an oral repair tool for inlay bonding. Background Art

[0002] In existing oral restoration technology, porcelain inlays have been widely used as an efficient and beautiful tooth restoration method. However, in actual clinical operations, the bonding process of porcelain inlays is often affected by a variety of factors, resulting in unsatisfactory bonding effects. These factors include limited patient mouth opening, differences in doctor's operating experience, and insufficient operating space. Therefore, how to improve the stability and accuracy of porcelain inlay bonding has become a problem that needs to be solved urgently in the current field of oral restoration.

[0003] Traditional ceramic inlay bonding mainly relies on the doctor's experience and feel to determine the position and direction of the ceramic inlay. At the same time, due to factors such as limited patient mouth opening and insufficient operating space, the doctor's operation in the mouth is often greatly restricted, resulting in a lack of stability and accuracy in the bonding of the ceramic inlay, which affects the restoration effect and service life.

[0004] In the prior art, the bonding effect of ceramic inlays is often improved by using adhesives, optimizing the bonding process, etc. However, these can only improve it to a certain extent and cannot solve the fundamental problems of stability and accuracy.

[0005] In summary, the utility model aims to solve the stability and accuracy problems existing in the bonding process of ceramic inlays in the prior art, improve the repair effect and service life, and optimize the patient's treatment experience. Utility Model Content

[0030] Example 1

[0031] A personalized passive constraint guide for inlay bonding, comprising a guide body 1 and an inlay 2, wherein the guide body 1 is made of a biocompatible resin material, the bottom of the guide body 1 is arranged to fit the surface of the patient's teeth, a placement channel 3 is drilled through the top of the guide body 1 in a vertical direction, and support platforms 4 are symmetrically fixedly installed on two opposite inner side walls of the placement channel 3; connecting hangers 5 are vertically fixedly installed on both sides of the top of the inlay 2, the inlay 2 enters the placement channel 3 through the top of the placement channel 3, and the connecting hangers 5 on both sides of the top are respectively placed on two support platforms 4.

[0032] It should be noted that the specific structure of the guide body 1 requires the collection of the patient's oral model and personalization according to the treatment needs. The inner wall of the bottom of the guide body 1 fits with the outer wall of the patient's teeth, so that the guide body 1 can cooperate with the patient's teeth to achieve the effect of fixing the guide body 1. The edge of the placement channel 3 is rounded to reduce the stimulation and discomfort of the device to the oral tissue; at the same time, the specific positions of the two support platforms 4 in the placement channel 3 are determined according to the occlusal surface morphology of the inlay 2 and the positions of the two connecting hangers 5 on the top of the inlay 2.

[0033] Specifically, in the present embodiment, the guide plate body 1 is installed in a fitting manner on the tooth surface of the patient, so as to facilitate accurate positioning of the tooth on which the inlay 2 is to be installed; by placing the channel 3 and the support platforms 4 on both sides of the channel 3, it is convenient to constrain and guide the inlay 2 so that the inlay 2 can accurately act on the target tooth, thereby increasing the accuracy of the bonding of the inlay 2.

[0034] Furthermore, a groove 6 is formed on the top edge of the support platform 4 away from the side wall of the placement channel 3 .

[0035] Furthermore, the guide plate body 1 includes two mutually symmetrical U-shaped support plates 101 and two connecting rods 102 for connecting the support plates. The inner side of the bottom of the U-shaped support plate 101 is set in contact with the surface of the patient's teeth. The two connecting rods 102 are fixedly installed between the two U-shaped support plates 101 and are located on the inner and outer sides of the patient's teeth. The opening formed by the two U-shaped support plates 101 and the two connecting rods 102 is the placement channel 3.

[0036] Furthermore, the connecting hanger 5 includes a vertical rod 501 and a horizontal rod 502, one end of the vertical rod 501 is vertically fixedly installed on the top edge of the inlay 2, one end of the horizontal rod 502 is vertically fixedly installed on the outer side wall of the other end of the vertical rod 501, and the horizontal rod 502 extends to the outside of the inlay 2 respectively.

[0038] Specifically, in this embodiment, through the cooperation between the cross bar 502 and the groove 6, the inlay 2 can be further supported in a limited position, thereby achieving the effect of passively restraining the inlay 2 and preventing the inlay 2 from shifting during the bonding process, thereby affecting the installation effect of the inlay 2.

[0039] It should be noted that the size and structure of the cross bar 502 and the size and structure of the groove 6 depend on specific circumstances.

[0040] Workflow: First, use an oral scanner to obtain a virtual oral model of the patient, then set the inlay 2 on the virtual oral model, and determine the structure of the guide body 1, the size and position of the placement channel 3, and the setting of the connecting fasteners, so as to achieve the purpose of personalized customization according to the patient's tooth structure and treatment needs, and then set support platforms 4 on both sides of the placement channel 3, and finally the designed guide body 1 is produced using 3D printing technology.

[0041] The prepared guide plate body 1 is fixedly installed on the patient's tooth surface according to the preset position, and then the doctor can accurately and intuitively observe the situation of the target tooth surface through the placement channel 3, and then the inlay 2 is placed on the target tooth through the placement channel 3, and at the same time, the connecting hanger 5 on the top of the inlay 2 is engaged with the groove 6 of the support platform 4, and then the connecting hanger 5 and the support platform 4 are initially bonded and fixed with an adhesive to further increase the stability of the inlay 2. Then the doctor begins to bond the inlay 2, and with the assistance of the guide plate body 1, acid etching, intra-oral positioning, adhesive application and uniform pressurization are performed, and finally, the connecting hanger 5 is ground off with professional tools, the guide plate body 1 is removed from the mouth, and the final blending is performed to make the surface of the inlay 2 smoothly transition to complete the entire treatment process.
