The present invention provides an improved orthopedic system for the modification of the distance between the maxilla and zygoma. In a preferred embodiment, the system includes proximal and distal footplates attached to an orthopedic device. The distal footplate is attached to the zygoma, with the proximal footplate being mechanically coupled to the maxilla. This mechanical coupling is achieved either through attachment directly to the maxilla or by attachment to a construct which is then wired to the patient's teeth. The orthopedic device, which may be a distractor, allows for modification of the distance between the maxilla and zygoma. The entire system can advantageously be placed intra-orally within a patient. In a preferred embodiment, the footplates are also detachable from the orthopedic device and are composed of a bioresorbable material, such that they will be absorbed by the patient's body. Methods for using this novel orthopedic system are also disclosed.

A removable magnetic dental appliance is provided. The magnetic dental appliance can be used in the treatment of various conditions, including but not limited to, snoring, sleep apnea, some forms of temporomandibular joint pain or inflammation, myofascial pain or bruxism. The appliance comprises an upper arch attachment member and a lower arch attachment member, each for removably engaging at least a portion of the dentition. A magnetic component is positioned anteriorly on one of the upper arch attachment member or the lower arch attachment member and a magnet-attracted element is provided on the other arch attachment member for magnetic engagement with the magnetic component when the upper and lower arch attachment members are substantially vertically aligned. The appliance uses magnetic force to selectively position the mandible while still permitting movement of the mandible relative to the maxilla for improved comfort. A use of the magnetic dental appliance and a kit comprising the magnetic dental appliance are also provided

A compliant brace is adapted for placement between the first region of the abutment and the elongate threaded implant. The compliant brace includes first, second, and third elongate extensions capable of engaging the cortical region of the maxilla or mandible, thereby minimizing micromotion and allowing for osseointegration despite immediate installation of a crown and immediate mechanical loading. The dental prosthetic may also include an adaptor for coupling the elongate threaded implant and the abutment. Methods for implanting dental prosthetics are also described.

The invention belongs to the computer aided surgical technique and maxillofacial plastic medical treatment equipment field and relates to a computer simulation method for predicting soft tissue appearance change after a maxillofacial bone plastic surgery. The method comprises the following steps that: spiral CT scanning is performed on the maxillofacial of a patient before the surgery; data are led into maxillofacial surgery design simulation software, namely, CMF-pre CADS, so that a three-dimensional maxilla and skin surface model is re-constructed; a bone segment is reset/shifted to a preliminary location; and the similarity of a pre-surgery prediction model and a post-surgery true appearance is judged through comparison through Geomagic software. With the method adopted, the post-surgery appearance and stomatognathic system functions can be recovered excellently; the appearance of soft tissues are symmetrical, harmonious and beautiful; the post-surgery satisfaction degree of the patient reaches 95%; the effects of the plastic surgery are stable; and long-term satisfaction is also very high.

Provided is a dental prosthesis formed as artificial molars designed for a lingualized occlusion, comprising the total of four teeth including a first premolar, a second premolar, a first molar and a second molar in a maxilla or a mandible, which are interconnected in a single prosthesis. An artificial maxillary molar is configured to have a blade form in a lingual cusp thereof, and a protrusion is formed in buccal cusps of a mandibular second premolar and a mandibular second molar so as to define a gap for gliding movement to take place between said artificial mandibular molar and oppositely-located artificial maxillary molars. A groove is formed in a bottom side of the four interconnected artificial molars, said groove extending throughout said four teeth and open at an end of the first premolar and an end of the second molar.

The invention is a three dimensional virtual articulator used for but not limited to diagnosing and treatment planning for dental and medical specialties, including orthodontics, prosthodontics, endodontics, periodontics, orthognathic surgery, implant positioning, crown and bridge and prosthesis design.

The operator enters patient-specific anatomical measurements for condylar angles, Bennett angle and shift, lateral excursive and protrusive movements, and maximum mandibular opening, and a selection of preset or customizable intercondylar distances to simulate the unique mandibular range of motion.

The patient-specific measurements create a customized complex polygon that illustrates the maximum limits of the mandibular range of motion. The operator is able to use onscreen controls to move the virtual mandible in relation to the virtual maxilla within the parameters described by the patient-specific measurements input by the operator.

The first point of contact as well as surface interferences can be marked on the dynamic surfaces of the two virtual arches.
