ISO/TS 19736 – Bonding Test Between Polymer Teeth and Denture Base Materials

Dentistry — Bonding Test Between Polymer Teeth and Denture Base Materials

 

 

ISO/TS 19736 specifies a test method for bonding of polymer teeth to denture base materials.

This test method is not designed to prove the properties of polymer teeth and denture base materials

This test method examines the bonding behaviour along the bonding surface. A measurement of the bond strength of polymer teeth to denture base material is only

meaningful if the fracture is at least partially adhesive, i.e. progresses along the bonding surface.

This test method is not designed to prove the properties of the polymer teeth and the denture base materials

Universal Testing Machine with built-in load cell, for measuring forces between 10 N and1000 N.

The load cell shall have a measuring inaccuracy of 1 % of the fracture force in accordance withISO 7500-1, Class 1


ISO/TS 19736  Test Procedure

Fix the polymer-mounted teeth in a mounting device .

Use a universal testing machine with a cylindrical flat shear pin for the application of the load  Use a guided shear-pin.

The load direction shall be on the palatal surface of the polymer tooth, vertical (approx. 90°) to the long axis of the tooth.

The shear pin shall with half of its area contact and apply the load on the incisal edge of the tooth.

The test equipment shall prevent any lateral deflection or change of position of the specimen.

Apply a crosshead speed of 1 mm/min until the specimen fractures

*** Before conducting this ISO standard , it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.

 

***PARSROS  offers several types of grips and fixtures which will enable you to perform a variety of tests

  that are accurate and repeatable.
