Placing a dental implant successfully comes down to millimetre level-precision. Being that the jaw has a limited amount of bone, with nerves and sinuses sitting close by, it is extremely difficult to know the precise position in which an implant should be placed to guarantee thirty or more years of strength and durability. For this reason, dynamic navigation is as necessary as it is beneficial. Dynamic navigation removes the guesswork from that decision by showing the surgeon exactly where the drill is, in real time, against a 3D scan of the patient’s own anatomy.
Our periodontists use the Navident dynamic navigation system, made by ClaroNav, across our Manhattan, Long Island, Nutley and Bronxville offices. It is used for single missing teeth as often as it is for full-arch cases.
What Is Dynamic Navigation For Dental Implants?
Dynamic navigation is a form of computer-assisted surgery that tracks the surgical handpiece during dental implant placement and displays its position live on a screen. The comparison most people find useful is satellite navigation in a car. The route is planned in advance, but the system keeps showing your position against that route as you drive, so any drift is visible and correctable immediately. A re-route is immediately given.
One of the top-rate dynamic navigation platforms established in implant dentistry is Navident, made by ClaroNav. It tracks the handpiece against CBCT data during placement. In other words, it is constantly guiding the human hand towards perfection of placement and implementation.
Conventional dental implant surgery offers two alternatives. In freehand surgery, the surgeon works from the plan, the scan and clinical experience alone. In static guided surgery, a surgical guide is fabricated in advance and seated over the teeth or gums so the drill can only enter at the planned angle. Dynamic navigation for dental implant placement sits between them, and it is the only one of the three that gives feedback while the implant placement procedure is actually happening.
How Does Navident Work During Implant Surgery?
The Navident workflow has four stages, and the first two happen before the patient is anywhere near the operating chair.
- Imaging. A CBCT scan is taken, giving a three-dimensional picture of the jaw, the nerve canals, the sinus floor and the available bone. A digital intraoral scan is taken alongside it and the two datasets are merged.
- Planning. Using implant planning software, the periodontist decides the exact depth, angle and position of every implant. Implant planning is driven by where the finished tooth needs to sit, not simply by where bone happens to be thickest.
- Tracing and calibration. A small tracking marker is fixed to the jaw and a second one to the handpiece. A calibration step registers the patient’s actual anatomy against the CBCT data, and a system check confirms the tracking is accurate before any drilling starts.
- Guided placement. Optical cameras follow both markers. As the osteotomy is prepared, the screen displays the drill’s angle, its depth and its deviation from the plan in millimetres. The surgeon can see the planned path and the actual path at once, and can verify the accuracy of the position at any point.
The osteotomy stage matters more than most patients realise. How the hole is prepared, how much heat is generated and how cleanly the bone is cut have more bearing on whether an implant integrates than the brand stamped on the implant itself. Real-time navigation lets that preparation be controlled precisely rather than estimated.
Static Surgical Guides Versus Dynamic Navigation: What Is The Difference?
Both are legitimate techniques in modern dentistry and we use both. They solve different problems.
| Static Surgical Guide | Dynamic Navigation System | |
|---|---|---|
| How it guides | A physical stent restricts the drill | On-screen tracking shows drill position live |
| Fabrication | Requires a guide to be manufactured in advance | No physical guide needed |
| Changing the plan | Fixed once the guide is made | Adjustable during surgery |
| Mouth opening | Needs vertical clearance for the guide and drill | Works with limited mouth opening, including back molars |
| Visibility of the site | Guide can obscure the surgical field | Field stays fully visible |
| Same-day treatment | Guide fabrication adds time | Scan, plan and place can happen in one visit |
A static surgical guide is excellent when the plan is settled and the anatomy is straightforward. Dynamic navigation earns its place when the situation may change, when access is tight, or when an extraction on the day alters what the surgeon finds. Choosing between a static guide and dynamic navigation is part of treatment planning.
Which Patients Benefit Most From Dynamic Navigation Implant Surgery?
Because the system needs no fabricated guide, the applications of dynamic navigation suit cases where flexibility matters:
- Immediate implant placement. When a tooth is removed and an implant placed at the same appointment, the socket shape is only fully known once the tooth is out. Dynamic navigation allows the plan to be adjusted then and there.
- Back molars and limited mouth opening. Vertical space is often too tight for a guide and a drill together.
- Sites close to nerves or the sinus. Seeing depth on screen as the osteotomy deepens provides a continuous check against the anatomy.
- Reduced bone volume. Where bone is limited, angling an implant to make use of what is available demands precision and accuracy that freehand surgery cannot reliably deliver.
- Full-arch reconstruction. The workflow for full-arch reconstructions requires several implant positions to relate correctly to one another, not just to the jaw.
It is worth saying plainly that this is not reserved for complex work. We use dynamic navigation for a single tooth as readily as for a full arch.
How Accurate Is Dynamic Navigation Compared To Freehand Surgery?
Published research in dental implantology consistently finds that accurate implant placement improves when either static or dynamic navigation is used instead of freehand technique, with deviation from the plan measured at the implant shoulder and as angular error. Reviews across dental implant navigation systems report that the accuracy of implant placement stays within clinically acceptable limits, and the accuracy of dynamic navigation compared to static surgical guide protocols has been shown to be comparable.
Two practical points sit behind those numbers. The accuracy of dental implant placement depends partly on the calibration and tracing performed at the start of the case, which is why the system check is not a formality. And there is a genuine learning curve. The technology assists a trained surgeon; it does not replace surgical judgement.
Who Offers Dynamic Navigation Implant Surgery In New York And New Jersey?
Dynamic navigation remains uncommon in general dentistry. Our five board-certified periodontists have been placing implants since as early as 1998, and Navident sits alongside the rest of our digital workflow rather than operating as a standalone piece of equipment.
That complete digital workflow includes cone-beam computed tomography for diagnosis, Trios intraoral scanning, Simplant and Navident implant planning software, photogrammetry for full-arch cases, Loocid BCP™ BoneBlade drills designed to limit the heat generated as the osteotomy is prepared, and an in-house laboratory producing restorations by 3D printing and Procera milling. Keeping the laboratory on site means the plan the surgeon makes in software and the tooth that is fitted are controlled by the same team.
Patients travel to us from across the tri-state area, and consultations for dental implant surgery are available at all four offices.

Frequently Asked Questions
Is Dynamic Navigation More Uncomfortable Than Ordinary Implant Surgery?
No. The tracking markers are small and the procedure itself is unchanged from the patient’s point of view. Because no bulky guide sits in the mouth, many patients find the appointment more comfortable, and computer-aided implant navigation often supports a flapless approach with less swelling afterwards.
Can Dynamic Navigation Be Used For Zygomatic Or Other Complex Cases?
Surgical navigation is used in oral and maxillofacial surgery for demanding anatomy, including zygomatic implant placement. Cases requiring quad zygomatic reconstruction are referred to colleagues who specialise in them.
How Long Does Treatment Planning Take?
Scanning and planning are usually completed before the surgical appointment. In same-day cases, the scan, the plan and the implant insertion can take place in a single visit, because no static guide has to be manufactured in between.
Is Dynamic Navigation Used For A Single Tooth Or Only Full-Arch Cases?
Both. A single implant in the aesthetic zone has very little margin for error in angle and depth, so real-time navigation is as useful there as it is across a full arch.
