All-on-4 is a universal dental term which refers to the procedure of placing all teeth on four implants. It is an implant-prosthetic concept in which the entire jaw – upper or lower – rests on four carefully placed dental implants.
A dental bridge is a fixed prosthetic restoration that fills the space created by the loss of one or more teeth. Unlike removable dentures, a dental bridge is permanently cemented and the patient does not remove it during everyday activities.
All on 6 is a well-known dental term whose meaning would be „all teeth on 6 implants“. It refers to a fixed prosthetic work placed on six implants inserted into a completely edentulous jaw.
Vizil prosthesis (skeletal prosthesis) is one type of prosthetic rehabilitation for partially edentulous patients. It can be applied in both the upper and lower jaws.
