The orthodontic appliance for correction of Class II or III malocclusions attaches to the maxillary arch on an archwire adjacent to the first molar and to the mandibular arch on an archwire in the cuspid or bicuspid area, and applies a low continuous force through the use of two plunger piston type devices, whether the mouth is open or closed. Dual acting piston cylinders are connected together, with first and second piston connecting rods extending in opposing directions from the piston cylinders. A first mounting element is provided at the exterior end of the first piston connecting rod for mounting the first piston connecting rod to at least one of the maxillary teeth, and a second mounting element is provided at the exterior end of the second piston connecting rod for mounting the second piston connecting rod to at least one of the mandibular teeth, for providing a continuous biasing force between the maxillary and mandibular teeth for treatment of malocclusions.

A subperiosteal bone anchor has a base that is thin and moldable so the base can be conformed to bone where it is to be placed. The base is formed as a plurality of arms, and leaves with central holes in the leaves so screws can urge the leaves against the bone. The edges of the base are scalloped, and very thin to facilitate bone overgrowth. Central to the arms is a stem extending up, and having a variety of connection mechanisms for attachment of orthodontic appliances.

An orthodontic appliance has two telescoping cylinders having springs therein to urge the cylinders apart. The outer cylinder is then slidably inserted into a third cylinder. The outer ends of the cylinders are attached to a patient's teeth so the springs exert a force on the teeth when the spring-urged cylinders contact the end of the third cylinder. The cylinders may be separable so the springs can be exchanged, or may be permanently fixed together. The attachments allow universal motion so the lower jaw can move to the full extent of the normal jaw without binding or destroying the appliance.

Resiliently expandable orthodontic device

A fixture for attaching a dental prosthesis to a dental implant has a base to be received on the implant, and a head attachable to the base. The base has an angled upper surface, and the head has an angled lower surface, the head being selectively rotatable with respect to the base. As a result, the head can be disposed with respect to the base so that the head will always be perpendicular to the gum line, even though the implant is angled with respect to the gum line. A non-round projection on the head engages a non-round recess on the base to prevent rotational movement when the fixture is installed, and a single screw extends through the head, through the base, and into the implant to hold the assembly together.

Adjustable implant fixture

An orthodontic appliance has a cylinder with a spring urged plunger therein. The spring is compressed when the plunger is moved into the cylinder; and, one end of the cylinder and the extending end of the plunger are attached between the teeth to be moved. The attachments to the teeth allow universal motion so the law is free to move in all directions anatomically possible. To extend between the upper and lower teeth, the cylinder can be slidable within a second cylinder. The second cylinder allows greater extension of the appliance while maintaining the integrity of the appliance.

Bicycle handlebars are adjustable about two axes for providing great versatility in handlebar style. A U-shaped member is fixed to the post of the bicycle and is rotatable at the post in conventional fashion. An axle is fixed to the extending ends of the U-shaped member, and hand grips are fixed to the axle. The hand grips are selectively rotatable about the axle, so there are two axes of rotation, the two axes being parallel to each other. The post preferably includes a toggle joint for quick release, in addition to a screw to allow the clamp of the post to be completely opened.

Handlebars with biaxial adjustment

An adjustable bracket for use in orthodontic appliances. The bracket can be fixed to a band to surround a tooth, or to a wire mesh to be cemented directly to a tooth. The bracket has a base to be carried by the tooth, and a movable member to which wires are attached, and a retainer to fix the movable member to the base. In the preferred embodiment, the base and the movable member have spherical surfaces so that motion of the movable member can dispose the bracket at any desired angle in any plane for the desired torque, and in all embodiments the movable member is rotatable about the retainer through 360 degrees and can be set at any desired angle.
