A U.S. Navy dentist and a medical engineer with expertise in 3D printing have recently developed a novel dental implant surgical approach comprising a customized dental ridge augmentation matrix (i.e. jig) and one or more dental implant surgical drill guides. The patented technology is available via patent license agreement to companies that would make, use, or sell it commercially.
Dental implants are used to support various dental prostheses via anchoring to the bone of the jaw or skull. In some cases, however, abnormal tooth loss can result in jawbone defects from adverse extraction socket healing. In such cases, due to the lack of supporting bone structure, conventional dental implants are not possible without first augmenting the osseous anatomy using bone grafts. Placement of dental implants can be an inconvenient, costly, and time-consuming process involving multiple clinical appointments. As such, there is a need for improved methods and devices that promote oral osseous reconstruction and surgical placement of dental implants.
In order to meet this need, WRNMMC scientists have developed an apparatus for the simultaneous surgical placement of an intraoral bone graft and a dental implant. The apparatus includes a customized ridge augmentation matrix and one or more dental implant surgical drill guides, where the matrix/jig is custom configured to the subject’s anatomy prior to the surgical placement to provide space maintenance for the intraoral bone graft; the drill guide comprises a port that can receive and guide increasing diameter implant osteotomy drills, and the drill guide may be articulated with and stably retained by the jig.
A portion of the matrix comprises a number of porous openings, ranging in size from about 1.0 mm to 9.0 mm in diameter, that serves as a point of articulation with the drill guide, a fixation screw port, a bone graft fill port, an implant access port, and/or a nutrient port. The drill guides are designed to control the angle and the depth of drilling during an implant procedure. The method allows for enhanced treatment planning for guided bone regeneration and prevents the need to cut, bend, adapt, preoperatively shape, or piece together commercially available titanium mesh membranes.
- Various kinds of bone graft materials, as well commercially available conventional dental implants and restorative components, may be used
- Eliminates need for additional fixation, but is compatible with commercially available fixation screws, if necessary
- Compatible with commercially available guided surgery kits
- Provides increased predictability of implant placement
- Reduces treatment time, cost, and morbidity
- Eliminates need for adjacent stabilizing teeth
- Businesses can commercialize the technology by licensing U.S. Patent Application 16/401,273 from the Navy
- License fees paid to the Navy are negotiable
- Businesses that license the technology may have the opportunity to pursue collaborative research with the inventor(s)
- TechLink guides businesses through evaluation and licensing; services provided at no cost
