Systems and methods for occlusal mandibular advancement block placement

A system for generating an orthodontic appliance with mandibular relocations structures, the system comprising:

• one or more processors;
• and
• a non-transitory computer readable medium comprising instructions that when executed by the one or more processors cause the system to carry out a method comprising:
• generating a treatment plan to move a patient's teeth from a first position toward a second position and including moving a jaw from a first position towards a second position, the treatment plan including a series of jaw movement stages to move the jaw from the first position towards the second position;
• iteratively, for a first stage of a treatment plan:
• placing, for a first stage of a treatment plan, a first mandibular relocation structure of a first pair of mandibular relocation structures on a lower jaw and a second mandibular relocation structure of the first pair of mandibular relocation structures on an upper jaw;
• determining, for the first stage of a treatment plan, a location for the first pair of mandibular relocation structures based on a first set of constraints;
• placing, for the first stage of a treatment plan, a first mandibular relocation structure of a second pair of mandibular relocation structures on a lower jaw and a second mandibular relocation structure of the second pair of mandibular relocation structures on an upper jaw;
• determining, for the first stage of the treatment plan, a location for the second pair of mandibular relocation structures based on a second set of constraints;
• and
• modifying the respective locations of the first and second pair of mandibular relocation structures for the first stage of the treatment plan based on a third set of constraints, wherein the third set of constraints includes a symmetry constraint based on a difference between a first distance and a second distance, the first distance being between a first mandibular relocation structure and opposing teeth on a first side of a jaw and the second distance between a second mandibular relocation structure and opposing teeth on a second side of the jaw;
• and
• providing the modified location of the first and second pair of mandibular relocation structures for the first stage of the treatment plan to implement the series of jaw movement stages.
