Method for dental restoration and related kit

A method of performing a dental restoration with a fluid polymer composition on a patient having an existing dental structure in need of dental restoration to a planned dental structure, the method comprising steps of

• (a) providing a dental mold comprising at least one buccal mold portion, at least one lingual mold portion, and at least one inlet port, wherein the buccal mold portion and the lingual mold portion are separate structures that together define a void volume corresponding to and defining occlusal surfaces of the planned dental structure when assembled at an interface;
• (b) preparing selected teeth to be restored;
• (c) fitting the dental mold over the existing dental structure, wherein the mold defines a space to be filled, and the space represents the difference between the existing dental structure and the planned dental structure;
• (d) injecting via the inlet port a fluid dental restoration polymer composition into the space;
• (e) curing the fluid polymer composition;
• and
• (f) removing the dental mold from the teeth to provide the planned dental structure in the patient.

A kit for forming a dental mold and for performing a dental restoration on a patient with the dental mold, the kit comprising:

• (a) a plurality of mold blanks for forming a buccal mold portion or a lingual mold portion of the dental mold, the blank molds having a shape and size to facilitate formation of buccal and lingual mold portions that together define a void volume corresponding to and defining occlusal surfaces of a planned dental structure;
• (b) a fluid dental restoration polymer composition curable on teeth to be restored;
• and
• (c) instructions showing at least one of the formation, assembly, and use of the dental mold.

A method of assembling a dental mold over a tooth and a gum of a patient having an existing dental structure in need of dental restoration to a planned dental structure, the method comprising steps of:

• (a) providing a dental mold comprising at least one buccal mold portion and at least one lingual mold portion, wherein the buccal mold portion and the lingual mold portion are separate structures that together define a void volume corresponding to and defining occlusal surfaces of the planned dental structure when assembled;
• (b) seating at least a portion of the buccal mold portion against a buccal side of the patient's gum or tooth;
• (c) seating at least a portion of the lingual mold portion against a lingual side of the patient's gum or tooth;
• (d) contacting the buccal mold portion and the lingual mold portion at an interface;
• and
• (e) securing the buccal mold portion and the lingual mold portion in place, thereby assembling the dental mold in a sealed configuration over the tooth and the gum of the patient, the sealed configuration defining a space between the dental mold and the existing dental structure.
