AI Technical Summary

Problems solved by technology

However, due to the complex shapes of complete dentures and the complex and diverse materials, it is difficult to ensure that each denture is firmly bonded to the base. In addition, each denture, base, and the whole after each denture is connected to the base are difficult to clean.
[0003] Therefore, there is still a large room for improvement in the existing technology

Embodiment 1

[0018] Embodiment one, a kind of bonding method of complete denture, comprises the following steps:

[0019] A. Abutment treatment, before applying the adhesive, the unexposed dentin tooth tissue is sandblasted with glycine or alumina to obtain a clean surface, and the exposed dentin is sealed with dentin adhesive to avoid Use bicarbonate sandblasting, otherwise the bonding effect of the dentin layer will be reduced. In addition, the cavity part is cleaned with a brush and treated with pumice powder or fluorine-free paste;

[0020] B. Treatment of the abutment, protecting the shape and connection holes of the abutment, and cleaning the surface of the abutment;

[0021] C. Restoration treatment, first zirconia-reinforced lithium silicate glass-ceramic is etched with hydrofluoric acid for 15-25 seconds, and then cleaned with pressured water spray;

[0022] D. Bonding. First, the abutment and the abutment are perfectly bonded, and then the abutment, the abutment and the zirconia...

Embodiment 2

[0025] Embodiment 2, when bonding, first shake the dentin treatment agent, use a disposable brush or micro brush to apply the etching agent, wait for 25-35 seconds, and let it dry naturally by air for 15-25 seconds.

[0026] In this embodiment, in the step B, the abutment includes a titanium abutment and a zirconium abutment, and the titanium abutment is cleaned by steam or ultrasonic to ensure that there is no contact pollution on the bonding surface, and the bonding surface treatment agent remains 1 minute, and fully dried by air, the inside of the zirconium abutment mouth was cleaned with alcohol, and the outside of the zirconium abutment mouth was cleaned with acetone.

Embodiment 3

[0027] Embodiment 3, when bonding, first stir the adhesive primer, then apply the acid etchant and wait for 25-25 seconds, then use air to blow gently for 15-20 seconds, any excess material must be removed, and it is necessary to use Light curing, the light curing time is 1-2 minutes.

[0028] In this embodiment, in the step B, the prosthesis is cleaned with an ultrasonic cleaner, and 98% alcohol is used for cleaning for 1-3 minutes.

Abstract

The present invention relates to the technical field of dentures, in particular to a bonding method for complete dentures. The present invention ensures the bonding between each denture and the base through four steps of abutment treatment, abutment treatment, prosthetic treatment and bonding. The connection is firm, and each denture, base, and the denture and base can be cleaned thoroughly.

Description

technical field [0001] The invention relates to the technical field of dentures, in particular to a bonding method for complete dentures. Background technique [0002] With the aging population in our country, the number of edentulous patients is still high. Complete dentures are still the most important restoration method for edentulous patients. However, the traditional production steps of complete dentures are cumbersome and complicated. The experience of doctors and technicians, There are high requirements for operating techniques and personal qualities. Therefore, if CAD / CAM technology can be brought into the field of complete dentures, it will be a boon for edentulous patients, young doctors and technicians. At the same time, removable complete dentures can also be used for attachment-supported overdentures, as well as implant-fixed complete dentures. However, due to the complex shape of the complete denture and the complex and diverse materials, it is difficult to e...
