All-on-4® treatment concept, using straight and tilted implants, was developed to provide edentulous and soon-to-be edentulous patients full-arch restorations that can function immediately. Two implants are placed vertically in the anterior or front region and two are placed at an angle of up to 45° in the posterior or back region. Using angulated abutments the tilt of the implants can be compensated and support a MALO CLINIC bridge.
