CHAPTER 13 Case Presentations: Immediate-Loading Zygoma Implant After the 6-month osseointegration period, the provisional prosthesis was removed and osseointegration was confirmed using resonance frequency analysis and reverse-torquing the implants. To simplify fabrication of the final prosthesis, the guided abutments were replaced using standard multiunit abutments. After connecting the multiunit abutments to the anterior implants and torquing them to 35 Ncm, the two anterior temporary titanium cylinders were trephined from the provisional prosthesis and replaced with multiunit temporary cylinders. The same replacement protocol was followed for the posterior zygoma implants by first connecting and torquing two zygoma multiunit abutments and trephining and replacing the temporary cylinders (Figures 13-55 to 13-59).
