Problems solved by technology

[0004] However, at present, the location of the cortical bone removal in PAOO surgery is determined by the periodontist combined with the patient's CBCT based on experience, and lacks a very accurate understanding of the anatomical structure of the operation area, resulting in low operation efficiency and high risk, especially for those who are just beginning to contact For novice doctors in this operation, the probability of iatrogenic injury such as tooth root injury is high

Embodiment 1

[0035] Such as figure 1 , 2 As shown in and 5, the present invention first discloses a guide plate system for periodontal accelerated osteogenesis assisted orthodontic treatment, which includes a guide plate body 1 that is 3D printed using transparent polymer materials. The upper tooth surface retaining plate 3 and the alveolar bone retaining plate 5 opposite to the alveolar bone cortex 4, the tooth surface retaining plate 3 is provided with a crown fitting surface that fits the tooth crown 2, and the alveolar bone The bone retention plate 5 is provided with a guide hole 6 for drilling the alveolar bone cortex 4, so that the drill bit 13 is guided through the guide hole 6, thereby improving the drilling efficiency and positioning accuracy, thereby reducing surgical complications the goal of.

[0036] In this embodiment, when setting specifically, the guide hole 6 is evenly arranged along the vertical direction of the tooth root, the guide hole 6 is located between the roots ...

Embodiment 2

[0046]In this embodiment, an ultrasonic positioning alarm device is added on the basis of the first embodiment. The ultrasonic positioning alarm device includes an ultrasonic probe 14 and an alarm device 17. Specifically, one side of the guide hole 6 is matched with a probe jack 12. For inserting the ultrasonic probe 14, the ultrasonic probe 14 faces the position of the drilled hole. The ultrasonic positioning alarm device also includes a wireless sensor 15 and a single-chip microcomputer 16, the ultrasonic probe 14 is connected with the wireless sensor 15, the wireless sensor 15 is connected with the single-chip microcomputer 16, and the single-chip microcomputer 16 is connected with the alarm 17. Among them, the ultrasonic probe 14 selects Ultrasonix#C5-2, the wireless sensor 15 selects the NRF24L07 wireless sensor, and the single-chip microcomputer 16 selects the STC-51 series STC89C52 single-chip microcomputer as the main control chip, and the alarm 17 selects the HYR1704U ...

Embodiment 3

[0048] In this embodiment, on the basis of Embodiment 1, as image 3 and 4 As shown, it also includes a roller card positioner installed on the alveolar bone retention plate 5, the roller card positioner includes an I-shaped guide rail 7 and a U-shaped slider 8, and vertical rails are arranged on both sides of the I-shaped guide rail 7. The extended chute 9 is provided with chute teeth, the two sides of the U-shaped slider 8 are pivotally connected to the roller 10, and the roller 10 is provided with roller teeth that can mesh with the chute teeth, and the I-shaped guide rail 7 A through hole 11 that can penetrate to the alveolar bone cortex is provided, the I-shaped guide rail 7 is provided with a through hole 11, and the guide hole 6 is arranged on the U-shaped slider 8, so that when the surgeon drills a hole in the vertical direction of the tooth root In the process, every time the roller 10 moves a position, the drill bit 13 can be quickly inserted into the drilling hole,...

Abstract

The invention discloses a periodontal acceleration osteogenesis auxiliary orthodontic treatment operation guide plate system and a forming method thereof.The periodontal acceleration osteogenesis auxiliary orthodontic guide plate system comprises an ultrasonic positioning alarm device and a guide plate body formed by 3D printing, wherein the guide plate body comprises a tooth surface retention plate capable of being attached and fixed to a dental crown and an alveolar bone retention plate opposite to alveolar bone cortex; the ultrasonic positioning alarm device comprises an ultrasonic probe and an alarm; a dental crown attaching face attached to the dental crown is arranged on the dental face retention plate; and a guide hole used for drilling the alveolar bone cortex and a probe insertinghole used for inserting the ultrasonic probe and facing a drilling position are formed in the alveolar bone retention plate. The bone cortical area can be accurately positioned, and the purpose of reducing operative complications can be achieved; furthermore, in a drilling process, ultrasonic positioning, monitoring and alarming of drilling depth can be achieved, the purpose of preventing tooth roots, nerves and important tissue structures from being damaged due to too deep drilling is achieved, and the safety of an operation is further improved.

Description

technical field [0001] The invention belongs to the technical field of medical auxiliary equipment, and specifically relates to a 3D printed periodontal accelerated osteogenesis assisted orthodontic treatment guide plate system and a forming method with an ultrasonic positioning and alarm function. Background technique [0002] Malocclusion affects patients' aesthetic, periodontal and mental health. With the development of the economy, more and more adults are undergoing orthodontic treatment, but the treatment time and cost lasting 2-3 years are a major challenge for adult orthodontics. How to shorten the time of tooth movement so as to shorten the time of the whole orthodontic treatment is the research focus of many clinicians and scientific researchers. In recent years, periodontal accelerated osteogenesis-assisted orthodontic treatment (Periodontal Accelerated Osteogenic Orthodontics, PAOO) can effectively accelerate the movement of orthodontic teeth. The resistance to...
