We have developed this level of technology and expertise for more than 2 decades. The G4 Implant Solution vastly improves on the All-on-4® treatment concept, which replaces all missing teeth with as few as four implants precisely placed in the upper and/or lower arch of the mouth. Our goal has always been to provide the most forward-thinking and luxurious restorative dentistry in the world. And today, G4 by Golpa is recognized as the new standard in dental implant care.
