Abstract
Systems and methods for mandibular reconstruction are provided. An example system may comprise a drilling guide comprising: (1) a body configured to register against two adjacent surfaces of a native mandible when the body is temporarily secured to the native mandible; and (2) a tube extending from the body. The tube may be configured to constrain orientation of a drill bit when inserted through the tube and into the native mandible to reduce off-axis tilt of the drill bit when forming a void in the native mandible. Size and orientation of the void may correspond with size and orientation of a phalange of a neo-mandible assembly to be received within the void.
Claims20
A drilling guide for forming a void in a native mandible, the drilling guide comprising:
- a body configured to register against two adjacent surfaces of the native mandible when the body is temporarily secured to the native mandible;
- and
- a tube extending from the body, wherein the tube is configured to constrain orientation of a drill bit when inserted through the tube and into the native mandible to reduce off-axis tilt of the drill bit when forming the void in the native mandible;
- wherein size and orientation of the void correspond with size and orientation of a phalange of a neo-mandible assembly to be inserted within the void.
A system comprising:
- a drilling guide comprising:
- a body shaped to conform to a native mandible section, and
- at least two tubes extending from the body at a pre-determined spacing and orientation corresponding to spacing and orientation of at least two phalanges of a neo-mandible assembly, wherein a respective tube is configured to constrain orientation of a drill bit when inserted through the respective tube and into the native mandible section to reduce off-axis tilt of the drill bit when forming a respective void in the native mandible section for receiving a respective phalange of the neo-mandible assembly.
A method comprising:
- installing a drilling guide on a native mandible of a patient;
- using the drilling guide to drill a void in the native mandible;
- removing the drilling guide from the native mandible;
- and
- attaching a neo-mandible assembly to the native mandible by inserting a phalange of the neo-mandible assembly into the void such that the phalange does not project against soft tissue of the patient.
