preparation example Construction

[0048] The present invention also provides a preparation method of a resin guide plate for adhering to the periodontal splint, comprising the following steps:

[0049] S1: Scan the patient's mouth with an intraoral scanner to obtain the patient's dentition information to form a digital model;

[0050] S2: Design the resin guide plate loose tooth fixation device according to the patient's digital oral model, figure 1 ;

[0051] S3: Design digital periodontal splint and splint positioning device on the patient's digital oral model, figure 2 ; If the fiber tape resin periodontal splint is made by manual indirect repair on the printed patient dentition model, the splint is scanned after the splint is completed to generate a digital model with splint information, and then the design of the splint positioning device is completed;

[0052] S4: The loose tooth fixing device and the splint positioning device are solidly formed by 3D printing / NC milling / die-casting.

Embodiment 1

[0064] A method for manufacturing a resin guide plate for a lingual periodontal splint used for auxiliary bonding indirect repair, refer to Figure 1-Figure 5 , proceed as follows:

[0065] S1: Scan the patient's mouth with an intraoral scanner to obtain the patient's dentition information to form a digital model;

[0066] S2: Design the resin guide plate loose tooth fixation device according to the patient's digital oral model, figure 1 ;

[0067] S3: Design digital periodontal splint and splint positioning device on the patient's digital oral model, figure 2 ; If the fiber tape resin periodontal splint is made by manual indirect repair on the printed patient dentition model, the splint is scanned after the splint is completed to generate a digital model with splint information, and then the design of the splint positioning device is completed;

[0068] S4: 3D printing / CNC milling / die-casting method is used to solidly form the loose tooth fixing device and the splint posi...

Embodiment 2

[0084] A method for making a resin guide plate for assisting the direct bonding of a labial fiber tape resin splint is performed according to the following steps: when a patient's periodontal splint needs to be arranged on the labial side, the loose tooth retention device adopts the design and manufacture of Embodiment 1 and The difference between the design and manufacture is S2. The front groove of the loose tooth retention device in the resin guide for auxiliary bonding of the periodontal splint needs to be set on the lingual side, wrapping part of the lingual side and the incisal end of the dentition. ,refer to Figure 9 . In this example, since the repositioning of the periodontal splint is not involved, the splint positioning device may not be provided.

Abstract

The invention relates to a multifunctional resin guide plate for assisting in bonding a periodontal splint and a preparation method of the multifunctional resin guide plate, the multifunctional resin guide plate comprises a loose tooth fixing device and / or a splint positioning device, and the splint positioning device is an optional device and can be detachably connected with the loose tooth fixing device. The multifunctional resin guide plate for assisting in bonding the periodontal splint is manufactured by utilizing a whole-course digital technical means according to a digital model of a natural curved surface form of a tooth, so that the problems of too thick bonding layer, poor stress and the like caused by loose tooth displacement in the bonding process can be avoided; through computer aided design software, the multifunctional resin guide plate is visual in design and convenient to modify and observe; the loose tooth retention device, the clamping plate positioning device and the periodontal clamping plate can be assembled and formed through the high-precision 3D printing / numerical control milling / die-casting forming technology, and the problem of assembly difficulty caused by entity errors is solved.

Description

technical field [0001] The invention belongs to the field of oral restoration and periodontal, and in particular relates to a multifunctional resin guide plate for auxiliary bonding of periodontal splints and a preparation method thereof, which can be applied to the bonding operation of any form of periodontal splint in the oral cavity, and is especially suitable for CAD / CAM for precise bonding of periodontal splints. Background technique [0002] Periodontal disease is a destructive disease of periodontal tissue caused by plaque, inflammation, trauma and other factors. As the most common oral chronic inflammatory disease in humans, the incidence rate in the Chinese population is still high. [0003] The direct harm of periodontal disease is the gradual loosening and displacement of the teeth, the inability of patients to chew, affecting the appearance, pronunciation and mental health. The loose teeth and the surrounding relatively healthy teeth are connected by splints to...
