The present invention relates to methods, devices, and systems for dynamically adjusting mandibular advancement. In certain embodiments, the devices and systems employ actuator assemblies configured to allow a subject's lower jaw to be advanced by a minimum amount (e.g., trigged by obstructive sleep apnea (OSA) or associated significant oxygen saturations), but still allow the subject to move their jaw further forward, laterally, and open/close on their own. In some embodiments, the devices and systems employ an oxygen saturation measuring sensor linked to a motor control processor that: i) advances extending shafts forward when the oxygen saturation measuring sensor detects significant changes to oxygen saturation levels or other conditions that may signal OSA (e.g. a signal from another sleep monitoring device), and ii) retract the extending shafts backwards when the oxygen saturation measuring sensor detect normal oxygen saturation levels or other condition is met (e.g. elapsed time, head position, etc.).
