repair composite resin bonding

Sticky crown (especially porcelain crowns), fixed denture adhesive, inlays,
Veneer, indirect method to complete resin restorations.
Usually a paste - paste formulations for bonding metal and opaque porcelain restorations.
Dual-cure: start, and then continue with chemically cured,
Suitable transparent adhesive restorations such as crowns, indirect method finished resin restorations.
Light-curing: Single component. portable dental unit Curing may be used alone, or light-cured matrix
Dual curing catalyst added. These products use the object consistent with the dual-cure.
In order to obtain the best physical properties, operation is the key.
Light-curing and dual-curing materials, light is a must,
After 10 minutes the polymerization generally get the best performance.
Some brands of adhesive material handling combined with dentin bonding agent,
Increases the complexity of clinical use.
These materials are widely used for bonding repair techniques, especially bonding ceramic restorations
Failure occurs and the material itself and operate in addition to technical defects, the
 Cyclic stress fatigue is a factor,
It is reported that the average life expectancy chemical curing repair of 8 years
Material itself is not much problem, endo motor the individual patient doctors and nurses have allergy symptoms,
Especially when using dentin bonding systems should avoid contact with the skin. n place is not complete, polymerization shrinkage and consequent leakage will be on micro-
Pulp causing pathological damage. The formation of micro-leakage can cause allergies and tooth repair failed.
Binding adhesive used to reduce the incidence of micro-leakage
[Disadvantages]
Advantages - High strength, low solubility, and enamel, dentin,
Alloy and porcelain restorations high surface adhesion properties (mechanical or chemical bonding).
Disadvantages - operating techniques sensitivity; seated difficulties; film thickness higher.
Pulp stimulation; micro-leakage; remove excess adhesive material more difficult.
In the adhesive porcelain veneers, composite resin inlays, crowns and other restorations good light transmission properties when
Using different colors, transparent, translucent or opaque,
Color coordinated with the prosthesis resin adhesive material is required to achieve beautiful.
All-ceramic restorations need to pass it with the adhesive material adhesive tooth tissues
Together to obtain strength, the hydrofluoric acid treatment to obtain ceramic adhesive side mechanical retention,
Then silane for further chemical processing.
The composite resin restorations complete curing of the adhesive the basic requirements.
Using light-cured resin adhesive material, the thickness should not exceed porcelain 1.5mm,
So as to ensure sufficient light to enter. If you use masking agents or porcelain veneers too thick,
Manufacturers recommend using a dual dual-cure resin paste adhesive material.
Resin adhesive material widely used for special aesthetic restoration of the adhesive,
The adhesive bridge dental cement is preferred. In addition to the lack of retention,
 Shedding fixed prosthesis adhesive, resin adhesive material can also be used to achieve the purpose.
Resin bonding material application more troublesome, these materials can not be completely avoided
Pulp irritation. Have dental products better retention is not a conventional prosthesis
Requires the use of resin-bonded materials.
Resin bonding material must be used with the adhesive,
 Avoid shrinkage of the resin and tooth structure caused fissures produced.
