Marginal fit of metal-free crown, observed in scanning electron microscope after three years in function
Journal Title: RSBO - Year 2009, Vol 6, Issue 2
Abstract
Introduction: Ceramics are considered an excellent choice as esthetic restorative material, but relevant questions like marginal fit require more attention in manufacturing than conventional systems. Objective: This work evaluated the marginal adaptation of an In-Ceram crown over a tooth that, after three years, had been indicated to extraction by orthodontics. Material and methods: The evaluation was by mean scanning electron microscope. Results and conclusion: It was found values of gaps between 157 and 390 μm, getting a statistic average considered greater than the accepted by literature.
