Abstract
A physical model of at least a portion of a patient's dentition has model dental surfaces corresponding to real dental surfaces of the patient's dentition. The physical model includes one or more targets, each configured for facilitating placement of an orthodontic appliance on the model at a desired location. The targets lack mechanical stops that are outwardly protruding from the original model dental surfaces. Also provided are a method of manufacturing a physical model for use in indirect bonding procedures, a method for indirect bonding for use in an orthodontic procedure, a method for providing an indirect bonding transfer tray for use in an orthodontic procedure, and a system for providing a physical model for use in indirect bonding orthodontic procedures.
Claims6
A method for manufacturing a dental model for facilitating placement of an orthodontic appliance on a patient's dentition, the method comprising:
- forming a positive physical model of at least a portion of the patient's dentition, including one or more teeth;
- and
- forming a recess in a surface of at least one of the one or more teeth of the positive physical model, the recess being formed at a desired location for the placement of the orthodontic appliance and shaped to receive at least a portion of the orthodontic appliance and constrain movement thereof in order to facilitate the placement of the orthodontic appliance at the desired location on the positive physical model, the recess including at least one edge face to which at least one edge of the orthodontic appliance abuts against to constrain movement of the orthodontic appliance at the desired location.
