INTRA-ORAL SURFACE NON-AQUEOUS HYDROPHOBIC COATING COMPOSITION AND METHOD

摘要

In order to meet the increasing demand for both dental and orthodontic treatment, many three-dimensional intra-oral scanning methods have been developed. The greatest problem of the current coating methods is that most aqueous imaging solutions/liquid are very difficult to completely dry. This feature also introduces necessary drying times of several seconds to tens of seconds. This requires the patient to sit still with his mouth open and increases the patient time in the dental chair. The underlying problem of these aqueous solutions remains that they are easily dissolved in saliva and easily removed by the tongue. Disclosed are improved intra-oral surface coating compositions and methods for preparing an intra-oral structure, such as a tooth, for three-dimensional (3D) scanning.
