Dr. Corrado Cazacu - "Full Mouth Rehabilitation using Zygomatic Implants: Completely Digital Approach"

Episode summary

Dr. Corrado Cazacu, a dental surgeon and CEO, founder, and lead surgeon of the DentOP implantology clinic in Bucharest, Romania (a certified ZAGA Center), describes a completely digital workflow for full-mouth rehabilitation using zygomatic implants. Cazacu has placed roughly 24,000 conventional implants, of which about 500 to 600 are zygomatic, and his clinics restore approximately 600 implants per month. He credits digital impression-taking via photogrammetry, rather than classic analog impressions, with delivering highly passive provisional and final restorations that reduce long-term failures. Adopting milled connections on multi-unit abutments and stronger provisional materials such as milled PMMA and milled Durachetal cut costs, improved accuracy, and lowered his broken-provisional rate to about 1%. He presents this protocol at the Edentulism Conference 2025 in Barcelona and is building a third, hospital-scale clinic as an international full-arch hub.

Key takeaways

Dr. Corrado Cazacu has placed approximately 24,000 conventional implants over his career, of which roughly 500 to 600 are zygomatic implants, and his clinics restore about 600 implants per month.
Cazacu's DentOP clinic in Bucharest uses a completely digital workflow with no classic (analog) impressions; photogrammetry-based digital impressions produce more passive prosthetic fits.
The digital protocol reduced cost, improved accuracy, and cut the broken-provisional rate to about 1%, with only around 2 of 100 patients returning to repair a provisional.
Moving away from bulky prosthetic parts toward milled connections directly on the multi-unit abutment reduced the number of components that could introduce lab errors.
Provisional restorations are made from milled PMMA or the harder milled Durachetal, chosen for durability over the long term.
The completely digital workflow is implant-agnostic and applies equally to conventional, zygomatic, nasal, and pterygoid implant systems.
DentOP ranked fifth among Romanian dental clinics in 2023 and is targeting third or fourth in 2024; Cazacu is building a third, hospital-scale clinic intended as an international full-mouth rehabilitation hub for Eastern Europe.
