DYNAMIC NAVIGATION FOR DENTAL IMPLANTATION
Mapping Virtual to Reality
A breakthrough in computer-aided implantology, Navident offers dental surgeons an easy to use, accurate, highly portable and affordable way to plan the desired restoration and implant placement on a virtual patient, then execute the plan on the real patient’s jaw.
The virtual patient’s jaw is created from the CT and, optionally, digital impression data, in seconds. The plan, including crowns and implants, is prepared in a few minutes and can be modified any time. During surgery, Navident shows the advance of the drill tip or implant in the patient’s jaw relative to surrounding structures and the implantation plan.
Let Navident help you be better
Do a better job
Plan the restoration on screen, then optimize the implant positions considering both bone and crowns. Then let Navident guide you to accurately implement your plan in the patient’s jaw.
Reduce harm to patient
Perform flapless surgery, leading to reduced patient discomfort, reduced risk of infection, and faster recovery. Avoid unintentional iatrogenic damage to nearby anatomical structures.
Increase your efficiency
Eliminate plaster models, wax-ups and fabrication of guides. Reduce chair time by eliminating raising and suturing flaps.
Reduce treatment costs
Leverage accuracy to reduce the need for custom abutments, bone augmentation and re-work. Use retrievable screw-retained, rather than cement-retained, superstructures.
Attract referrals
Demonstrate to patients your ability to leverage the latest technology to deliver better, safer, less invasive care.
Relax and enjoy
Reduce your mental stress. Sit up during surgery. Use exciting new technology. Increase your job satisfaction and extend your career.
Simplified workflow, which can be performed in a single appointment
Stent
A NaviStent is fabricated directly on the patient’s jaw
The process starts with a quick in-office preparation of a hot water thermoplastic stent, called NaviStent. The stability of NaviStent’s fit can be immediately evaluated to ensure predictable results.
Scan
Scan patient in a CT machine with a NaviStent and CT Marker in place
A “CT Marker” part containing a precision manufactured fiducial body is attached to the NaviStent and the patient is scanned as usual. Navident is compatible with all dental CBCTs on the market, including small field ones.
Plan
Plan restorative-driven implant placement
Use the CT alone, or add intraoral scans or any other surface (STL files). Create virtual crowns, then add the implants to best support them. The plan can be modified at any time, even during surgery. Navident is compatible with any implant size and type available on the market.
Place
Place each implant while getting real-time, dynamic feedback on a laptop
Navident maps the drill tip to the drill tag, maps the drill tag to the jaw tag and maps the jaw tag to the CT image. This process of calibration tracking and registration is extremely accurate and made possible because of our stereoscopic optical camera and our patented checker board patterns.
Dynamic over Static
“Real-time navigation is a valuable alternative to stereolithographic (static) guided surgery as it offers the clinician some advantages compared to the former technique. Using real-time (dynamic) navigation one can avoid the fabrication of a stereolithographic template resulting in a less expensive treatment. As navigation is considered as a dynamic guided surgery system, changes to the treatment planning (location and size of the implants, number of the implants, flap or flapless…) can be easily made intra-operatively. Also the tactile feeling during the drilling procedure, as well as the manual control over the implant stability, is still present when using navigation surgery.”

Flexibility
View the CT data and change the plan at any time, even during surgery.
Immediacy
Guidance immediately available following planning – no need to wait weeks for guide to arrive.
Predictability
More predictable – stent problems can be detected and corrected on the spot.
Safety
Accuracy check always available – large errors immediately observed and addressed.
Simplicity
User friendly and intuitive planning – no need to design the guide and sleeves.
Economy
Lower cost per procedure. No expensive kits or specific drills.
Irrigation
Better irrigation during drilling of open osteotomy site.
Access to implantation site
No need for longer drills which interfere or preclude usage in posterior implantation sites with minimal jaw opening.
Integration
Fully open – any implant, any drill system, any handpiece. No need to buy special kits.
Completeness
Guides the implant itself, not just the drilling.
Solution for Fully Edentulous Cases
For fully edentulous jaws, or when the teeth are insufficiently stable or expected to be removed during the implantation procedure, Navident offers a unique Bone Anchoring Solution. A single small diameter implant (SDI) is temporarily inserted in the jaw, either vertically or horizontally, to provide a stable bone anchor. A special version of the NaviStent arm, with a bracket designed to provide strong and stable coupling to the head of the implant, is then used to attach the CT-Marker or the JawTag to the jaw. The bracket has a built-in safety snap mechanism to prevent damage to the bone or the SDI when the CT-Marker or JawTag are accidentally hit.
“For the 30 implants where the mini-implant approach was used, mean deviations of 0.78 mm at entry, 1.22 mm at apex and 1.91° of angulation were achieved. These results are statistically consistent with the results obtained using Navident’s partially edentulous protocol.”

NOTE: Navident is cleared by the FDA in the United States for use with partially edentulous patients. This solution for use with completely edentulous patients is not currently available for use in the United States.

EvaluNav
The EvaluNav application, included in Navident, enables evaluation of the deviations between the planned and the actual position of implants appearing in a post-operative (“post-op”) CT scan. Once the pre- and post-op scans are loaded and registered to each other, the exact position of each implant is detected in the post-op CT and compared to its planned position in the pre-op scan. The deviations at entry and apex and angle are automatically computed and presented both visually and numerically. Provided the implant itself was inserted under guidance, EvaluNav is able to further separate guidance deviation (system error) from drilling deviation (user error).
“Having participated in guided surgery since 1999, first utilizing the beta version of 3D planning software and stereolithographic guides and ever since participating in the digital explosion of technology, I am now more excited than ever with dynamic navigation that Navident is leading. The workflow that we are implementing is awesome and I believe the future of guided implant treatment planning and delivery for our patients.”
