Digitalisation of the gold standard of implantology

SHLOMI, Israel: Over two decades ago, digitalisation started to transform dentistry, but the process has not been accomplished yet. We are currently in a hybrid phase, in which digital and conventional procedures are often combined. In 2018, Cortex’s fully digital system assumed its place in the digital dentistry world. The system provides the clinician with a complete digital workflow, from virtual implant planning to the final restoration.

Virtual implant planning, static guided surgery, dynamic freehand navigation systems and other CAD/CAM technologies have been undergoing a drastic evolution in the last few years.

The decision on whether to use a digital or a conventional procedure is highly dependent on the clinician’s individual preferences, and no recommendations can be made based on the present consensus.

For example, a septum case was solved using a combination of the virtual implant planning software Implant Studio (3Shape) and Cortex’s guided surgery kit that helps achieve correct placement of Cortex’s Magix dental implant, the design of which acts as a bone expander and allows for minimum bone drilling.

After clinical and radiographic examination, a virtual diagnostic impression and a CBCT scan were taken. The digital files were imported into computer-guided planning software and perfectly merged. The case was planned remote from the treatment place in the digital laboratory at the Cortex headquarters. After one week, the surgical template was received.

Placement of a Magix implant for the mandibular first molar was virtually planned for the septum site. The ideal position of the implant was virtually planned based on the anatomical architecture and prosthetic considerations. The angulation and vertical position of the implant were determined to minimise axial loading of the implant and create a proper emergence profile. A 3-D printed surgical template from a rapid prototyping machine was designed and fabricated for the surgery. The drilling osteotomy and implant placement process were smooth and precise, and the results were as planned.

As clinical cases in dentistry can vary greatly and have individual nuances, digital implantology allows for pre-diagnosis and pre-prepared optimal surgical workflow planning, avoiding unexpected challenges during the surgical execution.

It offers a number of benefits to the clinician as well as the patient. For some clinicians, it reduces the procedural time and offers more secure implant placement in complex cases. More importantly, it provides a link between the virtual prosthetically driven treatment plan and the actual surgery by transferring the simulated intervention accurately to the surgical site with the use of an individual surgical template, made specifically for each case. This approach provides the planner with prosthetically driven planning in order to assure an optimal final restorative result.

Visitors to IDS will be able to join hands-on sessions of the Cortex guided surgery system at Booth A010-C019 in Hall 3. 2.
