Inclusion criteria
Inclusion criteria: Participants over 18 years of age; both sexes; requiring replacement with the use of two unit prostheses on implants in the posterior region of the maxilla or mandible; with healthy adjacent natural teeth (no carious lesions or any stage of periodontal disease); favorable gingival profile (thickness greater than 1.5 mm) and sufficient bone tissue to perform the implantation surgery without bone grafts or augmentations

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| An improvement in the osseointegration of Hybridus implants is expected after the change in surface macrogeometry as assessed by the ISQ (Implant Stability Quotient) and radiographic evaluation over time;The maintenance and/or increase in peri-implant bone height is expected to be greater for Hybridus implants assessed by radiographic evaluation over time | — |
Secondary
| Measure | Time frame |
|---|---|
| It is expected that the 3D printing materials chosen to produce the prosthetic crowns will be able to withstand the oral environment with a survival rate of over 80% after 18 months. | — |
