 |  | belleGlass NG Opaceous Dentine more closely matches the coefficient of thermal expansion (CTE) of natural dentine. This means belleGlass Ng will look and act virtually the same as the natural tooth structure. | In-vivo measurements of wear over a five year period showed belleglass to average only a little over 1.2 microns a year – closer to the wear rate of natural teeth than any other material tested. | |
