Abstract:
A completely edentulous patient came to the outpatient clinic in MSA University seeking a fixed solution instead of his poorly retained mandibular complete denture. Upon clinical and radiographic examination, the posterior ridge was severely resorbed. Thus, the All-On-Four concept was indicated for this case. A CAD-CAM surgical guide was digitally designed and constructed in order to perform computer guided 4 implant placement using flapless surgical technique. After 4 months of osseointegration, implants were loaded with a fixed detachable hybrid prosthesis restoring both function and aesthetics.
