A jaw support device for supporting a patient's jaw during dental procedures. More specifically, a jaw support device comprising a headrest mount assembly, a split sphere assembly having a first locking mechanism, a ball joint assembly having a second locking mechanism, and a jaw rest assembly. The headrest mount assembly may attach to a dental chair headrest. The split sphere assembly may have a split sphere ball and an arm extension and may attach to the headrest mount assembly. Further, the split sphere assembly's first locking mechanism may lock the arm extension in place. The ball joint assembly may have a ball joint ball and may connect to the arm extension of the split sphere assembly. The jaw rest assembly may attach to the ball joint assembly and may be locked in place when the second locking mechanism is activated.

A balance assist and fall prevention assembly for preventing falls and providing balance assistance includes a plurality of rails and a harness. The rails are mountable to a ceiling of a structure and are selectively interconnectable so that respective rails are extend along an associated route in the structure that is routinely traversed by a user. A trolley is rollably engaged to the plurality of rails. The harness can be selectively donned by the user so that the harness is removably engaged to the user. A tether is engaged to and extends between the harness and the trolley. The tether is selectively length adjustable so as to extend substantially linearly between the harness and the trolley with the user standing substantially upright and beneath the trolley. The tether thus improves balance of the user and to prevents falling of the user.
