Description

Pressing tool for veneering bonding

Technical Field

The utility model belongs to wainscot technology field, concretely relates to wainscot is pressing means for bonding.

Background

The dental veneer is a thin sheet prosthesis which is attached to the surface of a tooth to repair and improve the tooth. Currently, in the process of adhering the tooth veneers, the tooth veneers need to be pressed by tweezers or bare hands. One of the difficulties of veneering bonding lies in that the pressing force during veneering bonding is not well controlled, and tests show that the vertical pressing force of the veneering on teeth is most suitable to be 0.8N-1N, the veneering is easy to suspend when the force is too small, the veneering is easy to fall off at the later stage, and the cracking of the veneering and the excessive overflow of the adhesive are easily caused when the force is too large, so that the bonding effect is influenced. In the past, whether the doctor presses the veneers to be in place depends on the hand feeling of the doctor, no standard exists, and the probability of some bonding failures can be caused by simply depending on experience. Training out the feel of a doctor also requires a large amount of manpower and material resources, and failed bonding can affect the confidence of the doctor and bring pain to customers.

In view of the above problems, the applicant has proposed a pressing tool for surface adhesion.
