These values were higher than those obtained in this study, and the difference may be related to the different methods and systems used to assess the fit: Matty used artificial teeth, cemented the crowns with a 5 kg load and sectioned them bucolingually. He also made three vestibular and palatine measurements, and his slices were separated by 100 microns. Francine compared Procera with metal porcelain crowns, reporting values of 54 and 29 mm respectively. He used molars and cemented the crowns with a 5 kg load. The values in the present study are lower, and once again this could be due to the different methodologies used. There are no reported studies about Zirkon zahn 'smarginal fit to compare the present study with.
Francine comparó coronas de Procera y metal porcelana, encontró valores de 54 y 29 µm respectivamente, utilizó molares y cementó las coronas con una carga de 5 kg, por lo que también se observa que probablemente por los sistemas y métodos utilizados los valores en este estudio son menores que los obtenidos por este autor y con lo que se afirma que existen diferentes metodologías para estudiar la adaptación marginal y de su elección, dependerá importantemente su interpretación.
