Abstract: An orthodontic anchorage system (10) is provided having a bone attachment portion (20), a bracket attachment plate (40), and a transmucosal neck (30) connected between the bone attachment portion and the bracket attachment plate. The bracket attachment plate has a mating surface (41) configured for adhesive attachment to a complementary mating surface (50) of an orthodontic bracket (51). The mating surface of the bracket attachment plate at least partially defines an internal void (44) that retains a portion of the adhesive (53) when the orthodontic bracket is attached to the bracket attachment plate.

Abstract: An adjustable fixation clamp having first and second clamp assemblies positioned about a shaft. The clamp assemblies may each have a pair of vise plates. Each pair of vise plates may define at least two receiving portions and insertion portions intersecting the receiving portions. The receiving portions of one clamp assembly may receive at least two fixation components such as screws, pins or wires. The receiving portions of the other clamp assembly may receive at least one connector such as a rod, bar and/or ring. A biasing structure may be positioned between the first and second clamp assemblies and may allow for the fixation components to be snapped into the receiving portions through the insertion portions. Two or more adjustable fixation clamps may be used to form an external fixation system. At least two screws, pins or wires may be inserted into bone and one of the clamp assemblies may be attached thereto. A guide may be used for insertion of screws, pins or wires into bone.
