All-On-4 surgery technique developed by Dr Paulo Malo of Portugal, is rapidly becoming one of the more popular surgery techniques for the fully endentulous patient. This surgery technique has proven to be not only cost effective, but highly successful for those patients with limited bone, without requiring bone graft, and also for those patients looking for immediate tooth extraction and implant placement. It requires immediate loading, and therefore patients do not have to go without teeth after surgery.
We at RDL have worked extensively with some of the leading All-On-4 surgeons in the country, and can be of great support to you - whether you are just beginning with this surgical technique, or you're a general practitioner looking to restore the provisional with a definitive restoration.
The final prosthesis of All-On-4 usually involves the construction of an acrylic wrap-around bar. RDL is one of the nation's leading All-On-4 restorative labs, and we use the Procera Implant Bridge because the CAD designed and custom milled bar creates not only a stronger bar, but a more precise, passive fit - all with less weight than a older style cast bar.
