GAITAN-FONSECA, C. et al. Push-out prototype for evaluating the bonding force between reconstruction materials in endodontic treatments. RIIIT. Rev. int. investig. innov. tecnol. [online]. 2020, vol.8, n.46, pp.1-10.  Epub 05-Fev-2021. ISSN 2007-9753.

The obturation and prosthetics reconstruction in an endodontic treatment involves the use of new materials, these materials must be passed for several test for proving their correct performance. One of these tests consists in measuring the bonding force between the reconstruction materials, and the dental piece by a mechanical test called “push-out test”. In this work, a prototype capable of making the push-out test that includes a friendly user interface for its operation is presented. The equipment is simulated in Fusion 360 making a finite element analysis to obtain the security factor and von Mises stress, and based on these, select adequate materials for its manufacturing. The prototype was tested for fracturing dental pieces with diverse internal materials and proved a proper operation that meets the actual specifications requested by dental professionals.

Palavras-chave : bonding force; finite element analysis; prototype; push and out test.
