Abstract

Methods and kits of materials and supplies for forming a dental prosthesis by an injection molding process in situ in a patient's mouth so as to correct the imperfect teeth of the patient's dentition. The imperfect teeth are corrected by injection molding the dental prosthesis in situ in the patient's mouth using a mold of a corrected model of the patient's dentition placed over the imperfect teeth. Adjacent teeth are covered with a polymer release material prior to injection molding of teeth to be corrected, such that the teeth to be corrected have at least one tooth between them draped with the polymer release material to provide a space adjacent to each of the corrected teeth. The corrected teeth are then covered with the polymer release material in a second round of treatment to complete the procedure on the remaining teeth.

Dependent claims

In a method for restoring teeth in need of restoration in a patient by providing a fluid dental restoration polymer composition which is curable on prepared teeth to be restored and curing the composition to provide the composition bonded to the prepared teeth in providing restored teeth, the improvement which comprises:

(a) preparing selected teeth to be restored for bonding with the fluid polymer composition;
(b) covering teeth which are not to be restored with a polymer release material;
(c) fitting a clear polymer composition mold over the teeth to be restored and the teeth not to be restored, which mold provides a closed space to be filled between the teeth to be restored and the mold which defines a shape of the restored teeth, wherein the mold has an inlet port for injection of the fluid polymer composition and an outlet port for removing any excess air and excess fluid polymer resulting from the injection;
(d) injection molding the fluid polymer composition into the mold to fill the space in the mold with the covered teeth and the teeth to be restored;
(e) curing the fluid polymer composition onto the teeth to be restored in the clear polymer composition mold;
(f) removing the mold from the teeth and the tape from the covered teeth to provide the restored teeth in the patient.
