Description

Positioning resin guide plate for bonding bridge

Technical Field

The utility model belongs to the mouth rehabilitation field, concretely relates to location resin baffle for bonding bridge can be applied to the bonding operation of the front teeth bridge that bonds in the oral cavity, is particularly useful for the accurate bonding of single-ended bonding bridge.

Background

The bonded fixed bridge, referred to as bonded bridge for short, was first in the seventies of the last century. With the continuous development of dental materials and the continuous progress of bonding technology, the bonded fixing bridge has become a common minimally invasive prosthesis in aesthetic dental restoration, and the bonded fixing bridge is mainly retained by bonding force.

Most anterior tooth bonding bridge retainers are tongue-side wing plates, and the most common form is a single retainer single-end bridge. If the double-end retainer is selected, under the functional state, torsion can be generated when the mobility and the moving direction of the abutment teeth on the two sides are inconsistent, so that the single-end bonding bridge is debonded, and because the retainer on the other side can still play a role, the retainer is not easy to be timely discovered by a patient, so that caries of the abutment teeth on the debonding side is caused.

The bonding of the bonding fixing bridge of the anterior tooth area is mainly positioned by hand at present. The design of the tongue side retaining wing enables the bonding fixing bridge to be prone to inclination or torsion when being bonded in place, particularly the difficulty in locating is increased after the tissue surface of the retaining wing is coated with the resin water gate heater, and the single end bonding fixing bridge is particularly suitable for the bonding fixing bridge. Once the bonding and fixing bridge does not reach the designed position when in place, the lingual wing plate of the bonding and fixing bridge cannot be tightly attached to the abutment, so that the bonding layer is locally too thick, secondary caries is easily caused, and bonding failure is possibly caused. An inaccurately seated bridge may also create occlusal interference as well as aesthetic defects. Although the preparation of the tooth body can help to limit the direction of the adhesive bridge in the position channel by preparing the mechanical retention shape and adjusting the adjacent surface convexity of the abutment tooth and the adjacent tooth, the grinding and cutting amount of the tooth can be increased invisibly, which is contrary to the concept of minimally invasive restoration.
