Guided (navigated) implant surgery is a modern method in which the position of the implant is precisely planned on a computer before surgery and then carried out in the mouth with high accuracy. Based on a three-dimensional CBCT scan and digital planning software, the optimal position, angle and depth of the implant are determined in advance; a surgical guide or a real-time navigation system then helps the dentist carry out that plan with high accuracy. In this guide we explain in plain language what guided implant surgery is, its static and dynamic types, its advantages, how it differs from the freehand method, and who it is suitable for.
What is guided (navigated) implant surgery?
Guided implant surgery is also called "computer-guided" or "navigated" implant surgery. Here the position of the implant is determined not by eye but on the basis of a pre-built digital plan. The dentist combines a CBCT scan (three-dimensional tomography) and a digital scan of the mouth in special software, virtually planning where, at what angle and at what depth the implant will sit. This plan is then transferred to the mouth either through a custom-made surgical guide or through a navigation system that tracks the position of the instruments in real time during surgery. In this way the surgery is performed according to a plan checked in advance rather than by estimation.
Static surgical guide and dynamic navigation
Guided surgery has two main approaches. In the static method a custom surgical guide is made from the plan — a template that fits over the teeth or gum and directs the drill strictly along the plan. In the dynamic method special cameras and sensors track the position of the instruments in real time on a screen and give the dentist instant feedback relative to the CBCT plan — this is called "real-time navigation." The goal of both methods is the same: to place the implant as close as possible to the planned position. Which approach is chosen depends on the clinical situation, the available equipment and the dentist's assessment.
Advantages of guided surgery
Building the plan in advance and carrying it out precisely offers a number of potential advantages:
- Accuracy: the implant can be placed closer to the planned position, angle and depth, which makes the subsequent prosthetic work easier.
- Safety: the location of the lower-jaw nerve, the maxillary sinus and the roots of neighbouring teeth is seen in advance, and a safe distance is kept from them.
- Less invasiveness: in suitable cases the surgery can be done without an incision or with a minimal incision (flapless), which may reduce swelling and discomfort.
- Predictability: because the result is modelled in advance, both the dentist and the patient better understand what to expect.
Precise planning also feeds into the decision of whether a temporary restoration can be fitted on the day of placement; that decision, however, ultimately rests on the primary stability measured at surgery and is not suitable in every case. The tooth fitted on the day is a provisional one, and the protocol does not shorten osseointegration. We cover it in detail in our separate guide to the immediate load dental implant protocol.
How it differs from the freehand method
In the classic "freehand" method an experienced surgeon places the implant relying on clinical experience and two-dimensional X-rays; this method has been used successfully for many years and is entirely sufficient in many simple cases. Guided surgery, however, turns the three-dimensional plan into a physical guide, reducing dependence on the human factor, and is especially useful in complex anatomy, limited bone volume, multiple implants or a planned flapless operation. Nevertheless, navigation does not guarantee the success of any method, and correct planning, quality equipment and the decision of an experienced dentist remain decisive. Which method suits you is determined by the dentist after an individual examination.
Who is it suitable for and what to expect?
Guided implant surgery can be an option for many patients, especially in the following situations:
- When the anatomy is complex — if there is proximity to the nerve, the maxillary sinus or the roots of neighbouring teeth, precise planning is especially important.
- When several implants or a full-jaw restoration are planned — to distribute the implants correctly relative to one another.
- When bone volume is limited — to make the most of the available bone safely.
- When a flapless (incision-free) operation and more comfortable healing are desired — the dentist assesses whether it is possible.
The guided-surgery workflow: three steps
1. CBCT and digital scan
A three-dimensional CBCT of the jaw and a digital scan of the mouth are collected.
2. Digital planning
The implant's position, angle and depth are planned virtually in software.
3. Guided placement
The implant is placed according to the plan using a surgical guide or real-time navigation.
