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. This means that first the tooth is virtually placed in the ideal position, then the implant is virtually planned underneath in the correct position. In this way it can be determined whether there is sufficiently high and sufficiently wide bone at this position. If there is a slight deviation, a change in the implant position, implant diameter or implant length is sufficient for a suitable implant placement; this is then incorporated into a drilling template and an operation protocol.
If too much bone is missing at this site, virtual bone grafting can be used to determine the missing bone. This virtual bone part is then milled from a foreign bone by a milling machine using 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 there 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, which ensures faster surgery, less swelling and less postoperative discomfort.
Planning also makes it possible to fabricate a temporary denture before implantation, so that the patient can be fitted with it immediately after the operation.
Advantages of navigated implant placement and backward planning:
- predictable results
- short operation times
- less swelling
- less postoperative discomfort
- immediate provisionalization on the same day
