The ball mill as a means of investigating the mechanical failure of dental materials
Objective: The main purpose of this paper is to present a new method of predicting clinical performance using mechanical loading in a ball mill. Methods: A series of four experiments (two involving a hybrid composite and one each on orthodontic brackets and bands) is described in which the ball...

RK Dentistry Objective: The main purpose of this paper is to present a new method of predicting clinical performance using mechanical loading in a ball mill. Methods: A series of four experiments (two involving a hybrid composite and one each on orthodontic brackets and bands) is described in which the ball mill was used to subject specimens to mechanical fatigue.

There is also a significant difference (P < 0.001) in the MST of sandblasted bands when compared to the untreated bands.
