An osteosynthesis plate is described, which is suitable for treating jaw fractures. The osteosynthesis plate has a plane of the plate as well as two plate sections 12, 14 with associated longitudinal axes 16, 18 extending substantially within the plane of the plate and inclined or staggered with respect to one another. Through openings 20, 22 inclined to the plane of the plate are formed in each of the two plate sections 12, 14. The angular alignments of the through openings 20, 22 within the plane of the plate differ with respect to a longitudinal axis 16 serving as reference line from one another by less than approximately 60°. In applications in the jaw region this slight deviation of the angular alignments permits an intraoral securement of the osteosynthesis plate. A transbuccal access through the cheek can thus be dispensed with.

A rodent immobilizing apparatus for use during experimental procedures, dissection, and sample procurement. The apparatus has two (2) points of adherence to the dissection board, one at the head / jaw region and one at the tail region. Generally, the rodent immobilizing apparatus includes a base, a bed positioned atop the base, a bank disposed along one side of the bed, another bank disposed along the opposite side of the bed, a string / wire hook affixed to each bank with string / wire therebetween, and a tail clip / clamp positioned at an inferior portion of the bed. The bed is slidable along the banks to accommodate different sized rodents. In operation, an anesthetized / euthanized rodent is positioned supine on the bed. The bed slides along the banks, so that the string / wire is hooked within the rodent's jaw. The tail is clamped to the bed, and the bed is pulled back to stretch out the rodent, thus immobilizing the rodent completely and rapidly.

A method is provided for relief of head, face and jaw pain by achieving the release of intra oral muscle spasms, trigger points, and myofascial dysfunction. The steps include locating intra oral treatment points, including locations of intra oral muscle spasms, trigger points, and myofascial dysfunction, in the mouth and jaw region of a human subject. A handheld device is provided with a central gripping portion, a first generally arcuate arm extending from one end of the gripping portion and terminating in a generally bulbous tip, and a second generally arcuate arm extending from the other end of the gripping portion and terminating in a generally flattened tip. The subject's mouth is opened sufficiently to pass one of the tips into the mouth. One of the tips is inserted in the subject's mouth and the tip is brought into contact with one of the treatment points. Pressure is applied to the treatment point until a release response occurs.
