Introduction
The aim of this poster is to describe the prosthetically-driven planning of dual-arch implant supported fixed dental prostheses. Digital workflow was employed to transfer intermaxillary records with a 3-D printed denture to plan implants’ position for an implant retain 3D printed hybrid prosthesis.
Methods
After unsuccessful guided bone regeneration and sinus augmentation for maxillary arch, hip graft was performed with the anticipation of planning for zygomatic implants. Previously made interim acrylic denture was used to verify vertical dimension against retained mandibular teeth. With the use of the obtained intermaxillary records digital workflow was followed starting from the mockup for verification of vertical dimension to fully guided mandibular surgical planning and immediate loading with a 3-D printed hybrid prosthesis. The failing dentition of partially edentulous mandible was used as an initial reference for stackable surgical guides during full-arch immediate implant placement
Results
None
Conclusion
The stackable guide option derived from a digital workflow increased the predictability of bone reduction, immediate implant placement, and immediate loading of provisional implant-supported fixed dental prostheses.
