Abstract:

Se propone la extensometría como método para el análisis del estrés de polimerización en los materiales a base de resina frente a los métodos experimentales tradicionales. Se describe y aplica el método propuesto (colocando en cavidades clase 11una banda extensométrica a 0'5 cms del margen cavosuperficial gingival), se analiza su validez y se valoran sus ventajas e inconvenientes. The aim of this study is to analyse the use of extensometry as a research method in restorative dentistry. We made class 11cavities in premolars previously selected, in which we set strain gauges 0,5 cm away from the margin cavity and parallel to the cavity' s floor. All phases in process were registered with strain gauges. The advantages and disadvantages of this technician dental materials are taking into account.
