**4. From analog to digital implantology**

#### **4.1 Computer guide treatment**

Technological advances in conventional medicine and implantology offer resources in the diagnosis and treatment of full arch rehabilitation with osseointegrated implants. The digitization of clinical cases thanks to computed tomography and the buccal scanner allow the elaboration of surgical guides which restrict movements in the 3 planes of space. Although some studies confirm that there is no statistically significant difference in digital versus analog procedures, the digitization process in implantology can help avoid human errors and injury to anatomical structures, help to determine a drilling sequence with a greater probability of primary stability, reduce the Surgical times and improve the perceptions of patients by having a modern treatment [30].

When we perform computer-guided planning and see that regenerative procedures around implants are not required, flap-free surgery allows for greater patient comfort, recovery, and acceptance of treatment (**Figure 3**).

#### **4.2 Computer-assisted dynamic navigation**

Computer-assisted dynamic navigation has been commonly employed in medicine, recently been implemented for dental implant surgery. The dynamic navigation uses optical motion technology to see the implant placement in real time, this helps to perform a flapless surgery and gives the surgeon the confidence of knowing that the implant placement is adequate. However, dynamic navigation is a recent practice that has a high learning curve in addition to requiring specialized medical equipment [31, 32].

#### **4.3 Biomodels in 3D**

Stereolithography is a solid three-dimensional prototype obtained through the processing of data obtained from computed tomography or magnetic resonance imaging. In recent years, stereolithographic manufacturing has made great strides in the quality, resolution, and precision of manufactured parts and is becoming increasingly important in medicine and surgery.

Surgical simulation on a 3D biomodel makes it possible to consider measurements, positions and emergencies of the implants on the prosthetic arch. In addition, its usefulness in the placement of long implants with skeletal anchors allows the surgeon to be prepared for the surgical procedure and minimizes the possibilities of errors, favoring the results of the treatment [33] (**Figure 4A**).
