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.
