Abstract
A method is used to provide a dental prosthetic with an upper boundary that cannot be seen when a patient smiles with the dental prosthetic installed. The method includes tracing a smile line on a dental appliance while the dental appliance is in the patient's mouth and while the patient is smiling. The method then includes transferring that smile line from the dental appliance to a study cast of the patient's mouth. The study cast is then scanned to create a three-dimensional digital model that includes the transferred smile line. The three-dimensional digital model is used to generate a surgical plan and surgical hardware for installation of the dental prosthetic. The dental prosthetic may include a full arch restoration.
Claims20
A method comprising:
- (a) inserting a dental appliance into a patient's mouth such that the dental appliance covers a set of teeth in the patient's mouth, wherein the dental appliance includes an anterior surface;
- (b) tracing a line along the anterior surface while the patient smiles, wherein the line is traced along a boundary of one of the patient's lips;
- and
- (c) removing the dental appliance from the patient's mouth with the traced line on the dental appliance.
A method comprising:
- (a) inserting a dental appliance into a patient's mouth such that the dental appliance covers a set of upper teeth in the patient's mouth, wherein the dental appliance includes an anterior surface;
- (b) tracing a line along the anterior surface while the patient smiles, wherein the line is traced along a lower boundary of an upper lip of the patient's mouth;
- (c) removing the dental appliance from the patient's mouth with the traced line on the dental appliance;
- (d) placing the dental appliance on a study cast of the set of upper teeth;
- (e) transferring the traced line from the dental appliance to the study cast;
- scanning the study cast to create a three-dimensional digital model of the study cast including the traced line;
- and
- (g) generating one or both of a surgical plan or surgical hardware based on the three-dimensional digital model.
A method comprising:
- (a) inserting a dental appliance into a patient's mouth such that the dental appliance covers a set of upper teeth in the patient's mouth, wherein the dental appliance includes an anterior surface;
- (b) tracing a line along the anterior surface while the patient smiles, wherein the line is traced along a lower boundary of an upper lip of the patient's mouth;
- (c) removing the dental appliance from the patient's mouth with the traced line on the dental appliance;
- (d) placing the dental appliance on a study cast of the set of upper teeth;
- (e) transferring the traced line from the dental appliance to the study cast;
- scanning the study cast to create a three-dimensional digital model of the study cast including the traced line;
- (g) generating a bone reduction guide based on the three-dimensional digital model, wherein the bone reduction guide is configured to guide a bone reduction procedure to reduce bone in the patient's mouth to a point above the lower boundary of the patient's upper lip;
- and
- (h) generating a dental prosthetic based on the three-dimensional digital model, wherein the dental prosthetic is configured to have an upper boundary that will be obscured by the patient's upper lip when the patient smiles with the dental prosthetic installed in the patient's mouth.
