Computer-navigated implantology: an innovative treatment method
The objective of any dental implant treatment is to provide the patient with fixed dentures – and this should be done as efficiently as possible and with the least invasive means. Apart from excellent quality, high precision and reproducibility are paramount to the treatment.

Concerns about accuracy
Conventional surgery aided by surgical guides has always been a good treatment option due to its minimally invasive nature. Nevertheless, the level of accuracy achieved with this method has been the cause of some concern in the past. For many dentists this represents a drawback.
Completely digital procedure
The advanced solutions offered by digital dentistry – in combination with innovative intraoral scanners and software modules for guided interventions – are taking dental surgery to the next level, enabling dentists to provide their patients with a new kind of treatment approach. We refer to it as “computer-navigated treatment for immediate implant placement and provisional restoration”. It entails a precision-guided digitally based surgical and prosthetic protocol, which allows the dentist to place a fixed provisional restoration immediately following the placement of the implants.
Visualization of the dental implant
The Implant Studio software enables the dental team to establish the final position of the dental implants and design the immediate provisional restoration and the surgical guides. For this purpose a preoperative intraoral scan of the patient’s mouth and a digital volume tomography (DVT) data set are generated. The two digital data files are then merged into one, which allows the implants to be “virtually” placed.
This approach immensely simplifies the collaboration between the dentist and the dental technician: The clinical case can be planned collectively. The virtual placement of the dental implants assists in establishing the final position of the implants as well as the anatomy of the jaws, the bone density and the position of the planned denture. Furthermore, the software allows you to design the surgical guide in the STL-format (.stl) of the intraoral scan and get it ready for production. The use of an intraoral scan instead of a DICOM-file considerably enhances the precision of the results.
Are you wondering how to make your dental practice fit for the 21st century? Do you want to remain successful and efficient in the future? Then maybe our check list will be of help to you.
The provisional restoration is placed immediately after the insertion of the implant, according to the above mentioned computer-navigated procedure. The temporary denture is designed and produced by the dental technician with the help of the previously described computer software.
Placement during the surgical intervention
Provisional crowns and bridges are milled from Telio CAD, a temporary composite restorative. Subsequently, they are finished and bonded to a Ti bonding base, e.g. Viteo Base. As a result, the digitally created provisional restoration can be placed on the implants in the course of the surgical procedure.
Ready for immediate loading
During the surgical intervention – after the surgical guide has been placed – the incisions are prepared according to the specific immediate loading concept. In order to achieve the desired surgical conditions for the immediate loading of the restorations, small adjustments can be made to the surgical protocol. Furthermore, the Osstell device is regularly used to determine the Implant Stability Quotient (ISQ).
This method provides the patient with an esthetic and functional provisional restoration immediately following the surgical intervention. The restoration is the result of an effective blend of excellent dental lab work and the latest technological fabrication protocols. This innovative procedure benefits patients and dental professionals in the following ways:
- The treatment is quicker, since fewer and shorter appointments are necessary.
- Precision is heightened.
- The captured date is digitally stored, and therefore the restorations are reproducible.
- The reduced need for anaesthetics heightens the efficiency of the treatment.
