Description

Novel accurate positioning accessory for bracket-free invisible appliance

Technical Field

The invention relates to the field of dental instruments, in particular to a novel accurate positioning accessory for a bracket-free invisible appliance.

Background

Resin accessories are needed to be bonded on the tooth surface before invisible correction, and the aim is to ensure that the invisible correction device in a transparent tooth socket shape is tightly attached to the tooth surface to play a role in retention, so that the resin accessories can assist in correcting the tooth to move in the three-dimensional direction so as to achieve the purpose of correction. The accessory is necessary in the invisible correcting process and can assist the correcting device to be in place and the resin bulge for tooth movement. The accuracy and success of the bond between the attachment and the tooth surface is critical to invisible appliances. The attachment is bonded by filling resin in the groove of the attachment bonding template of the invisible appliance, then putting the tooth socket of the attachment bonding template on the dentition in place, and bonding the resin with the tooth surface which is subjected to acid etching in advance by light curing and illumination. For the accuracy of attachment bonding, it is necessary to have the bonding template closely conform to the tooth surface and fully seat, otherwise it may result in improper attachment bonding position or improper attachment bonding morphology. At present, accessories are mainly bonded by resin materials in a transparent polyester template mode, and the mode has the following defects: 1. the template accuracy is not high, resulting in errors in the thickness of the bonded attachment profile, purely in terms of tooth movement effect expression. 2. The template is worn in the daily wearing and taking off process, so that the expression of the moment generates errors. 3. Often the attachments fall off during the correction process, the attachments need to be re-bonded, and thickness errors and loss of moment expression of the template attachments occur during the re-bonding process. I.e. the corrective force applied to the attachment by the step of correction is lost in re-bonding. 4. Attachment adhesion can cause resin to spill over the base, leading to errors and potential dental plaque accumulation. 5. When the accessory is adhered, a dental assistant is required to press or enable a patient to bite the joint surface of the adhering template of the invisible appliance through cotton so as to ensure the complete positioning of the template, a doctor applies pressure points on the buccal surface of the adhering template through dental auxiliary equipment forceps or probes so as to overflow redundant resin, the shape correctness of the accessory is ensured, and then the adhering template is cured by light under the conditions of light curing and the like. However, in the existing operation, a dental assistant and a doctor need to press the bonding template tooth socket simultaneously, so that the operation is inconvenient and the patient is uncomfortable. In addition, because the invisible appliance accessory bonding template tooth socket is made of a plastic material with a smooth surface, the invisible appliance is easy to slip when being pressed by applying force to the buccal surface by using the existing dental appliance, the bonding template tooth socket cannot be stably controlled to be always attached to the tooth surface, and then the light-curing bonding process of the accessory is influenced, so that the operation is inconvenient, resin cannot be attached to the tooth surface, the accessory bonding fails, and then the accessory needs to be bonded repeatedly, or the phenomenon that the accessory is successfully bonded, but the bonding force is small, and the accessory falls off in the treatment process occurs.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a novel accurate positioning accessory for a bracket-free invisible appliance, so that the accessory can be accurately and tightly attached to the tooth surface.

In order to achieve the purpose, the invention provides the following technical scheme: a novel accurate positioning accessory for a bracket-free invisible appliance comprises an invisible appliance accessory and an accurate positioner connected with the invisible appliance accessory; in order to improve the manufacturing precision of the accessory, the accessory is molded separately in advance, and the invisible appliance accessory is a personalized customized and molded geometric body matched with the orthodontic tooth surface.

In order to improve the accuracy and success rate of the adhesion between the attachment and the orthodontic tooth and make the attachment simple and convenient to install, the accurate positioner is manufactured by 3D software design and a 3D printer according to the shape of the orthodontic tooth, and is matched with the orthodontic tooth to form an arm-type retention sleeve which is made of resin.

In order to simplify the accurate positioner and ensure the installation accuracy, the accurate positioner is formed by mutually crossing a longitudinal retention arm and a transverse retention armImitationThe upper part of a longitudinal retention arm of the arm-type belt-shaped sleeve with the outline on the surface of the tooth is jointed with the occlusal surface of the orthodontic tooth, and the first and second side parts are jointed with the palatal side surface of the labial and buccal surface of the orthodontic tooth; the upper part of the transverse belt is attached to the near-far middle occlusal surface of the orthodontic tooth.

In order to ensure that the accurate positioner does not generate displacement on the orthodontic tooth, the first side part and the second side part of the two longitudinal retention arms are respectively provided with a first transverse auxiliary retention arm and a second transverse auxiliary retention arm which are matched with the labial-buccal surface and the side surface of the jaw of the tooth.

In order to facilitate the separation of the accessory from the precise positioner, the invisible appliance accessory is connected with the top end part of the side part of the longitudinal retention arm, and the connection mode can adopt an adhesive structure or an embedding structure.

In order to make the attachment easier to be separated from the precise positioner, the scarf structure of the invisible appliance attachment connected with the top end part of the first longitudinal retention arm is as follows: the top end part of the first retention arm is provided with an embedding groove matched with the invisible appliance accessory for arranging the invisible appliance accessory.

In order to improve the strength of the accessory, the invisible appliance accessory is made of ceramic or resin.

The invention has the beneficial technical effects that: 1. because each accessory and the accurate positioning sleeve are manufactured and molded independently, the precision error of each accessory generated when the original template is adopted for manufacturing is avoided, and the accessories can be accurately positioned; 2. because the accessory can be manufactured separately in advance, the accessory material can adopt ceramic material, so that the strength of the accessory is enhanced, and the phenomenon that the previous accessory is frequently fallen off or abraded when the accessory adopts a resin accessory can be avoided; 3. the installation is simple and convenient, and quality problems can not occur.
