Abstract: Embodiments of the invention are directed to a maxillary implant for advancement, expansion and stabilization of repositioned bone sections of a maxilla. According to embodiments, a maxillary implant includes a first plate having a bone attachment portion. The bone attachment portion has a bone contacting surface defining a first plane and one or more screw holes. The first plate has a coupling portion defining a second plane and has a post-opening. The maxillary implant includes a second plate having a top panel and two side panels. The two side panels each has a bone contacting surface defining respective third and fourth planes and one or more screw holes. The maxillary implant has a post projecting from the top panel in the posterior direction. The post and the post-opening jointly form an interface which allows the first and second plates to be adjustable relative to each other.
