Spiel: Bonding Systems (Enamel, Dentin, Compomer, Interfusion, Resin Cement) OVERVIEW OF BONDING SYSTEMS:

A. Goals of Bonding (and Adhesion):

1 . Sealing

B. Definitions and Terminology pertaining to Adhesion:

1 . Terminology for adhesion:

a. Adhesive- material forming the layer

m. Adherend- base being bonded

c. System (EBS, DBS) and

providers (EBA, DBA, ABA)

2 . Adhesive devices:

a. Adhesive layer

(Adherend/ Adhesive)

b. Adhesive joint

(Adherend-1/ Adhesive/ Adherend-2)

C. Steps in Formation of Good Adhesion (for Retention):

(1) Clean adherend

(2) Great wetting

(3) Personal adaptation

(4) Bonding

Oral Materials" Enamel-Dentin-Amalgam Bonding and Composite Cements" Page 2 D. Connect Strengths (Measure of Devastation of Adhesion): (1 MPa = 145 psi)

1A. Shear Bond Strength (SBS):

> SBS = (1. 5-2) x THE BEST SPINNER'S;

> SBS = (1/3-1/4) x TBS

> Enameled surface bonding = 18-22 MPa

> Dentin bonding sama dengan 10-35 MPa

> Concoction bonding sama dengan 3-22 MPa

> SBS for dentin = 165 MPa

2A. Tensile Connect Strength (TBS):

E. Factors determining functionality:

1B. Micro-Shear Bond Strength (SBS)

2B. Micro-Tensile Connect Strength (TBS)

1 ) Operator factors (etching, cleansing, drying, and bonding techniques)

2 . Design (preparation) and Substrate factors (smear layer, wetness content,... )

a few. Materials factors (product, modulus, thickness,... )

4. The teeth location elements (lesion style, local morphology, flexure, arch)

a few. Patient factors (F exposure, diet, era, occlusal stress,... )

F. Style (functions) of bonding devices (3, a couple of, 1-components):

1 . Fitness (clean and/or...
