The bridge design and production of the posterior teeth bonding

1. after dental bonding bridge retainer design

The connection angle of the missing gap side of the cheek side of the line angle and far from the center line of the buccal to the preparation of the adjacent ditch. A high degree of lack of gap proximal edge of the Long Line should not be less than 3mm, whether side should be cut grinding of the adjacent tooth tissue, in order to guarantee the strength of the proximal connection body, the occlusal surface of the tongue side should cover 2/3 of the lingual cusp.

2. Production methods

Abutment preparation: nearly missing teeth side of the adjacent surfaces, the tongue and adjacent buccal axis surface corner suddenly reduced to the gingival 1 ~ 2mm, adhesive surface co-gingival height of minimum 3mm proximal surface of the two abutment teeth nearly missing teeth gap side of the Preparation of co-care nest, and take advantage of the occlusal surface dental instruments occlusal District. Base occlusal gingival direction should be made ​​common seated Road.

Production of metal bridge: Preparation of an impression, filling anhydrite model, the production of the overall stent wax type, embedding, casting. Metal stents have good resistance retention (metal flange thickness of about 0.5mm), the case does not affect the bite and beautiful, to maximize the tongue flap (solid planes), cheek sudden Hop surface care. Gingival flap edge should leave the gingival margin of 1mm, the edge into a blade-shaped. Bicuspid bridge cheek surface can be used porcelain or composite resin (should retention device) making the need for aesthetic,

Try them: bonded bridge trying on metal stents with the fit of the tooth, bridge abutment surface tight gums, multi-directional pressure does not move, do not shake and What are the factors that affect the price of whitening not dislocation, early point of contact. Light cleansing covered with plastic sheets by the polished, sandblasted and coated with coupling agent of the bonding surface or electrolytic treatment.

Bonding: the bonding surface of the abutment teeth etching to complete the adhesion of composite resin bonding.
