Instead to use 6 to 8 implants to retain dental bridge in all-on-4 system only 4 implants are used becuse lateral implants are placed under at an angle which allows longer implants that can handle bigger forces.
Installation of the lateral implant under an angle makes possible to use larger areas and volumes of already available bone. In this way we avoid bone augmentation or it is reduced to a minimum. Shortens the treatment time and reduce costs.
LESS SURGERIES – LESS TIME
Abutments are placed in the same intervention with imlants. For All-on-4 implant therapy implants are not covered with mucous membrane. This eliminates the need for additional surgical intervention for removing gingival mucosa covering implnts.
