ALL ON FOUR IMMEDIATE FUNCTION CONCEPT
The All-on-four concept tilting the distal implants in the edentulous arches
1)Improves the prosthetic support
2) Increases the inter-implant distance and provides better implant anchorage in the bone by using longer implants.
3) Immediate loading of implant-supported dental prostheses is documented in the literature with high predictable and success rate for the edentulous mandible.
4) The development of new protocols for immediate loading of dental implants has replaced from placing multiple implants and loading a few to placing only four implants as an optimal number to restore a completely edentulous mandible.
5) Rehabilitation of posterior edentulous mandible can at times be hindered by bone atrophy distal to mental foramen and bite forces that are more posterior in the dentition.
6) Implants are placed in fairly upright position in anterior edentulous mandible.
7) It is often necessary to fabricate a bilateral cantilever which sometimes up to 20mm long to provide the patient with good chewing capacity in the molar region.
8) The distal tilting of implant may be advantageous with reduction of cantilever length.
