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 that rests on the teeth, gum or bone and contains metal guide sleeves. The drills pass through these sleeves at the planned angle and depth.
• Dynamic navigation: A system in which the drill’s position is tracked on screen in real time 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 the implant to be placed 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. For the patient, 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 the sinus.
2. Intraoral scanning: Teeth and gums are turned into a digital model with an optical scanner instead of impression material.
3. Merging the data: 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 following 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 the 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), which can reduce post-operative swelling in some patients.
• Communication: Patients can see their plan on screen and understand the treatment better; team members work on the same digital file.
• Immediate temporary prosthesis: Since planning is done in advance, in suitable cases a temporary prosthesis for the day of surgery can be prepared beforehand — useful for patients travelling to Istanbul on a tight schedule.

How accurate is guided surgery?

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

The main factors contributing to deviation are: small errors when merging CBCT and scan data, incomplete seating of the guide in the mouth (especially with guides resting only on the gum), the play between guide sleeve and drill, and the patient’s mouth opening during surgery. That is why a safety distance from structures such as the nerve canal and sinus is left during planning, and the dentist never gives up control during surgery.

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 space
• Areas close to the lower jaw nerve canal or the upper jaw sinus
• In the aesthetic zone, when precise positioning according to the crown’s natural emergence profile is needed
• Full-arch plans in which several implants must be placed in 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 limiting, especially for back teeth.
• Additional radiation and cost: CBCT and guide fabrication are extra steps. CBCT should only be taken 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 there is insufficient attached gum or a need for bone grafting, open surgery may be more appropriate.
• Risk of over-reliance: The guide is a tool. Even though average accuracy is good, the chance of deviation in a single case is never zero.

Is healing 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 extent of 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 reshaping is also done during guided surgery, healing is similar to conventional surgery.

Aftercare advice is also similar: cold compresses on the first day, taking the medication your dentist recommends regularly, avoiding smoking, not touching the surgical area in the first days and eating soft food. If an immediate temporary prosthesis has been fitted on the implant, do not bite hard foods with it, because it is important for the implant not to move during healing so that it can fuse with the bone. At follow-up visits both wound healing and the bite of the temporary prosthesis are checked.

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 plenty of bone, freehand surgery can be a suitable option even when digital planning is done. Which approach suits you is decided together after examination and imaging.
