Navigated Implantation and Backward Planning
Modern imaging techniques have entered implantology in recent years and allow preoperative planning that enables very safe and predictive implant placement.
The 3-dimensional imaging of the bone enables backward planning. First, the tooth is virtually placed in the ideal position, then the implant is virtually planned in the correct position below it. In this way it can be determined whether there is sufficiently wide and high bone at this position. If the deviation is slight, a change in the implant position, implant diameter or implant length is sufficient for a suitable implantation. This is then used to fabricate a drilling template.
If too much bone is missing at this point, the missing bone can be determined by virtual bone grafting. This virtual bone part is then milled from a foreign bone by a milling machine in the CAD-CAM process (in the near future printed via 3D printer).
Through a surgical procedure, this manufactured bone part is screwed under the oral mucosa where it is needed. It heals for 4 - 6 months. Then the implant can be placed in the ideal position.
By making drilling templates that allow guided implantation, it is possible to implant very gently, possibly even without opening the oral mucosa. This ensures faster surgery, less swelling and less postoperative discomfort.
Planning also makes it possible to fabricate a temporary denture before implant placement so that the patient can be fitted with it immediately after surgery.
Advantages of navigated implant placement and backward planning:
- Predictable results
- Short operation times
- Less swelling
- Less postoperative discomfort
- Immediate provisionalization on the same day
