All-on-four treatment with narrow platform implants in reduced restorative space for moderate atrophic edentulous ridge

The use of dental implants to treat edentulous maxilla and mandible is a well-accepted concept in modern dentistry. However, it is difficult and challenging in atrophic jaws. All-on-four implant concept is an alternative for resorbed jaws, as it obviates extensive bone grafting and waiting time and often provides immediate function. In our article, we describe the use of narrow platform implants (3.3 mm) for a moderate atrophic complete edentulous case with the above concept. The studies with narrow-diameter implants for complete reconstruction are inadequately reported. We followed our case for 3 years after the delivery of final prosthesis.
