Light therapy apparatus and methods

A method for treatment of a bone disorder or for biostimulation of bone or soft tissue, comprising:

• irradiating light via at least one extra-oral light source of a light therapy apparatus through a patient's skin toward a region of the jaw bone of the patient in an amount that is effective for treatment of the bone disorder or for biostimulation of bone or soft tissue, the light therapy apparatus comprising:
• a support including a head set having a frame configured to register with a bridge of a patient's nose and a pair of arms extending rearwardly from the frame, the support defining a first slot having a curvature that substantially follows a curvature of a maxillary bone;
• a yoke slidably coupled to the support along the first slot such that the yoke is repositionable relative to the support along a length of the first slot, the yoke defining a second slot, the second slot being transverse to the first slot;
• and
• at least one extra-oral light source configured to be slidably coupled to the yoke along the second slot, the light source being repositionable relative to the yoke along a length of the second slot, the head set configured such that the at least one extra-oral light source is biased against a face of the patient when the apparatus is worn by the patient.
