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.
Claims17
A physical model of at least a portion of a patient's dentition, the physical model being a positive physical model and comprising model dental surfaces corresponding to real dental surfaces of the patient's dentition, the physical model further comprising at least one recessed target configured for facilitating placement of an orthodontic appliance on the physical model at a desired location, the recessed target comprising a recessed mechanical stop shaped to constrain movement and receive a perimeter edge of the orthodontic appliance in order to position and align the orthodontic appliance during placement of the orthodontic appliance on the physical model.
A method of manufacturing a physical model for use in indirect bonding procedures, comprising:
- (a) providing a physical model of at least a portion of the intra oral cavity of a patient, the physical model being a positive physical model;
- (b) determining desired positions of at least one orthodontic appliance with respect to the intra oral cavity to enable an orthodontic procedure to be carried out;
- and
- (c) providing at least one recessed target on the physical model, the recessed target being configured for facilitating placement of the orthodontic appliance on the physical model at a desired location, the recessed target comprising a recessed mechanical stop shaped to constrain movement and receive a perimeter edge of the orthodontic appliance in order to position and align the orthodontic appliance during placement of the orthodontic appliance on the physical model.
A method for indirect bonding for use in an orthodontic procedure, comprising:
- (a) providing a physical model of at least a part of the intra oral cavity of a patient, the physical model being a positive physical model and comprising at least one recessed target, the recessed target being configured for facilitating placement of an orthodontic appliance on the physical model at a desired location for enabling the orthodontic procedure, the recessed target comprising a recessed mechanical stop shaped to constrain movement and receive a perimeter edge of the orthodontic appliance in order to position and align the orthodontic appliance during placement of the orthodontic appliance on the physical model;
- (b) using the recessed target, locating the orthodontic appliance at the desired location on the physical model;
- (c) providing a transfer tray over the physical model such as to anchor the orthodontic appliance within the transfer tray;
- (d) transferring the orthodontic appliance to the real intra-oral cavity of the patient.
A method for providing an indirect bonding transfer tray for use in an orthodontic procedure, comprising:
- (a) providing a physical model of at least a part of the intra oral cavity of a patient, the physical model being a positive physical model and comprising at least one recessed target, the recessed target being configured for facilitating placement of the orthodontic appliance on the physical model at a desired location for enabling the orthodontic procedure, the recessed target comprising a recessed mechanical stop shaped to constrain movement and receive a perimeter edge of the orthodontic appliance in order to position and align the orthodontic appliance during placement of the orthodontic appliance on the physical model;
- (b) using the recessed target, locating the orthodontic appliance at the desired location on the physical model;
- (c) producing a transfer tray over the physical model such as to anchor the orthodontic appliance within the transfer tray;
- and
- (d) removing the transfer tray, with the orthodontic appliance in situ therein, from the physical model.
A system for providing a physical model for use in indirect bonding orthodontic procedures, comprising a computer controlled manufacturing center configured for producing, on a positive physical model of at least part of the intra-oral cavity of a patient, at least one recessed target, the recessed target being configured for facilitating placement of an orthodontic appliance on the physical model at a desired location for enabling an orthodontic procedure to be carried out on the patient, the recessed target comprising a recessed mechanical stop shaped to constrain movement and receive a perimeter edge of the orthodontic appliance in order to position and align the orthodontic appliance during placement of the orthodontic appliance on the physical model.
