Definitions
- This invention relates generally to osteotomy cutting and drilling guides and bone fixation implants used for example in orthognathic surgery or related bone treatments involving osteotomies or bone repair, and in particular wherein the guides and implants are shaped and configured based on computer-aided design to conform to the surface topography of the bone. More particularly, the invention relates to such guides and implants are provided with registration members or structures to insure proper positioning and alignment of the devices on the bone surfaces, and even more particularly to such guides and implants wherein the registration members abut the
- orthognathic surgery also known as corrective maxillofacial or jaw surgery, which is surgery designed to correct conditions of the jaw and face related to structure, growth, sleep apnea, TMJ disorders, malocclusion problems owing to skeletal disharmonies, or other orthodontic problems that cannot be easily treated with braces.
- orthognathic surgery also known as corrective maxillofacial or jaw surgery, which is surgery designed to correct conditions of the jaw and face related to structure, growth, sleep apnea, TMJ disorders, malocclusion problems owing to skeletal disharmonies, or other orthodontic problems that cannot be easily treated with braces.
- osteotomy means the division, or excision of bone.
- the osteotomies may be performed on the maxilla (e.g., a LeFort I), the mandible (e.g., a sagittal split), or the chin (e.g., a genioplasty).
- Modern orthognathic surgery makes use of computer-aided design and manufacturing techniques whereby technicians create pre-operative and post-operative 3-D models of a patient, whether virtual or physical, showing the current configuration of the jaw and/or face before surgery and the desired configuration after surgery.
- Guides for cutting the osteotomy and/or marking the location(s) of the osteotomy on the maxilla, mandible or chin as well as for drilling holes to receive bone fastening screws are manufactured.
- Fixation implants configured such that when attached to the bone segments after the osteotomy the bone segments will be properly positioned relative to each other are also produced.
- the guides conform to the pre-operative configuration of the patient’s bone structure, such that the surgeon can easily position the guide in the proper location.
- the surgeon then uses the guide to mark the location for the osteotomy and either marks or drills holes through apertures in the guide, the holes being properly positioned to receive the bone screws used to fasten the fixation implants to the bone segments with the bone segments positioned in the desired post-operative relationship.
- the guides may be produced with physical structures to guide the osteotomy saw.
- One type of guide is referenced as an occlusal guide in that a portion of the guide is designed to abut and rest on the upper surfaces of the teeth.
- a guide is manufactured out of a plastic material and a portion of the guide is configured to match or confirm to the surfaces of a plurality of adjacent teeth, typically 4 or 5. This portion is often referred to as a splint and is the portion of the guide that insures proper positioning and alignment.
- a bridging member then connects the splint to one or more bone-conforming members, the bone- conforming members being configured to conform to a portion of the bone surface on the maxilla, mandible or chin.
- the guide cannot be mis-positioned on the patient, as the splint portion will mate with the plurality of teeth only in the single position that properly aligns and locates the one or more bone-conforming members on the bone surfaces. While this occlusal guide structure is useful, the bulkiness of device, and in particular the bulkiness of the splint portion conforming to the teeth surfaces, may interfere with or make difficult the marking of the osteotomy and the drilling of the fixation holes.
- the guide is removed and the fixation implants are affixed to the separated bone segments.
- the fixation implants are produced to conform to the desired post-operative configuration of the patient’s bone structure, and in like manner to the guides, the inner surfaces of the implants which abut the patient’s tissue are configured to conform to the surface topography of the area onto which they are to be affixed.
- the invention in various embodiments is a surgical osteotomy and drilling guide or a bone fixation implant, or the combination of such a guide and implant in a kit, used in computer-aided orthognathic surgery, or similar bone repair or bone modification surgery.
- the guide is structured to properly locate the osteotomy marking members and implant fixation screw-receiving holes on the bone surfaces of the patient, and/or the cutting of the osteotomy or the drilling of implant fixation screw-receiving holes.
- the guide comprises at least one registration or dental-interface member configured to reside in the gap or valley formed between the exposed lateral portions of adjacent teeth, one or more bone-conforming members configured to conform to the bone surface topography of the maxilla, mandible or chin, and one or more bridging members connecting the one or more bone-conforming members to the dental- interface member, the bone-conforming members comprising the drill guide apertures and the osteotomy marking or cutting surfaces.
- the implant is structured to properly locate a bone- conforming member on the bone segments after an osteotomy has been performed, the implant comprising at least one registration or dental-interface member configured to reside in the gap or valley formed between the exposed lateral portions of adjacent teeth and one or more bridging members connecting the dental-interface member to the bone-conforming member, the one or more bridging members and at least one dental-interface member being structured such that they may be removed from the bone-conforming member after it has been affixed to the bone segments.
- the dental-interface member is a generally U-shaped or semicircular member positioned about a single tooth, the dental-interface member configured to abut against the facial or buccal (i.e., frontal outer) surface of the exposed tooth crown and having a pair of curved or hooked arm members which reside adjacent to and abutting the mesial and distal (i.e., lateral to the middle and lateral to the rear, respectively) surfaces of the exposed tooth crown.
- the guide and implant have one or more dental-interface members, each of which is mounted on a dedicated bridging member, wherein instead of encompassing a single tooth the dental-interface member is configured to abut the mesial, facial and distal side of the crown of a first tooth and the mesial, facial and distal side of the crown of a second, adjacent tooth.
- the dental-interface member or members have an inner tooth-conforming surface that conforms to the exposed crown surface. In this manner there is only a singular position for the dental-interface member that correctly mates and aligns with the tooth crown, thereby insuring proper placement and positioning of the bone-conforming member of the guide or implant.
