What is guided implant surgery?

In the conventional method, the dentist decides where the implant goes during surgery, based on X-rays and examination findings. In computer-assisted implant surgery, this decision is made before surgery in a three-dimensional digital environment. There are then two ways of transferring the plan to the mouth:

• Static guide: A template resting on the teeth, gum or bone with metal guide sleeves inside. The drills pass through these sleeves at the planned angle and depth.
• Dynamic navigation: A system in which the drill position is tracked live on a screen using cameras and markers. No physical template is used.

Static guides are further divided into those that guide only the first drill, those that guide all drilling but leave implant placement freehand, and fully guided systems that also allow the implant itself to be placed through the guide.

How does the digital implant workflow work?

The ITI guide on digital workflows describes the process in four main stages: diagnosis, planning, surgery and prosthetics. From the patient’s point of view, the steps are roughly as follows:

1. Examination and 3D imaging: Cone beam computed tomography (CBCT) is used to assess bone height and width and structures such as the nerve canal and sinus.
2. Intraoral scanning: Instead of impression material, the teeth and gums are turned into a digital model with an optical scanner.
3. Merging the data: The CBCT (DICOM) and scan (STL) files are superimposed in the planning software.
4. Prosthetically driven planning: First the ideal position of the missing tooth is designed virtually, then the implant is positioned where it can best support that tooth.
5. Guide fabrication: Once the plan is approved, the surgical guide is designed and 3D-printed.
6. Surgery: The guide is seated in the mouth, its fit is checked and the implant is placed according to the planned protocol.
7. Digital impression and prosthesis: After healing, a scan body is attached to the implant to take a digital impression; the crown or bridge is made with computer-aided design and manufacturing (CAD/CAM).

What are the advantages?

• Seeing ahead: Bone volume, neighbouring roots and anatomical structures are examined before surgery; any need for bone grafting is planned from the start.
• Harmony with the prosthesis: Because the implant is placed according to the position of the future tooth, the screw-channel position and aesthetic result can be more predictable.
• Smaller surgical field: Where bone and gum are adequate, it may be possible to work without opening the gum (flapless); this may reduce post-operative swelling in some patients.
• Communication: Patients can understand their treatment better by seeing their plan on screen; team members work from the same digital file.
• Immediate temporary prosthesis: Because planning is done in advance, in suitable cases a temporary prosthesis to be fitted on the day of surgery can be prepared beforehand.

How accurate is guided surgery?

This is one of the most studied topics in the scientific literature. Systematic reviews report that the difference between the planned and the actual implant position is on average about 1 mm at the implant entry point and slightly more at the tip. However, the same studies also show that in some cases this value can reach several millimetres.

The main factors contributing to deviation are: small errors in merging CBCT and scan data, incomplete seating of the guide in the mouth (especially with guides resting only on the gum), the play between the guide sleeve and the drill, and the patient’s mouth opening during surgery. This is why a safety distance to structures such as the nerve canal and sinus is left during planning, and the surgeon keeps control throughout.

Who is it suitable for?

Guided surgery may be preferred especially in the following situations:

• Cases with limited bone volume where the implant must be placed in a narrow area
• Areas close to the lower-jaw nerve canal or the upper-jaw sinus
• The aesthetic zone, when precise positioning according to the crown’s natural emergence profile is needed
• Full-arch plans in which many implants must be placed parallel or at specific angles
• Patients for whom a temporary prosthesis is planned on the day of surgery

What are the limits and risks?

• Mouth opening: Sufficient mouth opening is needed for the guide and long drills; this can be restrictive, especially for back teeth.
• Additional radiation and cost: Taking a CBCT and producing a guide are extra steps. CBCT should be taken only when clinically necessary, with an appropriate field of view and dose.
• Limits of flapless surgery: When the gum is not opened, the bone cannot be seen directly; if attached gum is insufficient or bone grafting is needed, open surgery may be more appropriate.
• Risk of overconfidence: The guide is a tool. Although average accuracy is good, the possibility of deviation in an individual case is never zero.

Is recovery different after guided surgery?

The basic biology of healing — the implant fusing with the bone — is the same with freehand and guided methods. The difference is mostly in the size of the surgery. When working through a small opening without lifting the gum, stitches may not be needed and swelling in the first days may be more limited. On the other hand, if bone grafting or gum correction is also done during guided surgery, recovery is similar to conventional surgery.

Aftercare recommendations are also similar: cold compresses on the first day, regular use of medication prescribed by the dentist, avoiding smoking, not touching the surgical area in the first days, and a soft diet. If an immediate temporary prosthesis was fitted on the implant, hard foods should not be bitten with it, because it is important for the implant not to move during healing for fusion to occur. At follow-up appointments both wound healing and the bite of the temporary prosthesis are assessed.

Digital planning at our clinic

At Yayla Dental Akademi in Istanbul, implant planning is carried out jointly by a digital prosthetic dentist and a specialist in periodontology. The IZEN Zenex implants we use hold the “Clean Implant” certificate. We would also like to point out that guided surgery is not necessary for every patient: in simple single-tooth cases with ample bone, freehand surgery can be a suitable option even when digital planning is done. Which approach is right for you is decided together after examination and imaging.
