Introduction. Short implants represent a valid alternative to bone regeneration techniques. In addition, metal-free prosthetic materials have several advantages for predictable rehabilitation. This case report is aimed at illustrating the advantages of fixed implant-prosthetic rehabilitation on short and ultrashort implants and metal-free prosthetic materials. Case report. A 66-year-old male patient with bone atrophy was treated with temporary denture placement performed based on a rapid protocol. Once the tissues after extractions matured and aesthetic/function was studied, short implants were prosthetically placed, and a fiber-reinforced composite (FRC) bar was digitally designed for a double full-arch fixed rehabilitation. The 2-year follow-up showed the absence of peri-implantitis signs and a stable occlusal relationship of prostheses. Discussion and conclusions. The FRC material has excellent aesthetic properties and is low cost with a simplified and fast workflow owing to digital dentistry methods. Further studies are still needed to confirm the effectiveness of long-term therapy; however, the combination of new minimally invasive surgery and prosthetic advances seems to be very promising.
