Abstract: A system and method for custom molding dental trays is disclosed. The system includes a hot air source and heat chamber, wherein a thermoformable dental tray is placed within the heat chamber and heated to the appropriate temperature. The heat chamber may include air escape holes to allow for uniform heating. Furthermore, the heat chamber may incorporate a fan or other air removal device to improve uniform heating.

Abstract: An apparatus and method is disclosed for treating a tooth with an active agent such as a tooth whitening agent comprising a stint having an internal region defined by an internal surface. A plurality of indentations are formed in the internal surface for retaining the active agent to maintain the active agent in contact with the tooth when the stint is applied upon the tooth. The stint is molded from a sheet of plastic material with the indentations being formed by an abrading process such as abrasive blasting or the like.

Abstract: An apparatus and method is disclosed for an improvement in the treatment of a tooth or teeth. The improved method comprises the steps of making a model of the tooth and molding a stint to overlay the model of the tooth. The stint defines an internal region for receiving a retaining material therein. An active agent is inserted into the retaining material and the stint containing the retaining material and the active agent is placed upon the tooth. The improved apparatus comprises a stint having an internal region and an external region with the internal region of the stint being defined for overlaying the tooth. A retaining material is disposed within the internal region of the stint to retain the active agent for enabling the active agent to be maintained in contact with the tooth when the stint is inserted upon the tooth.
