title: The maxillary M-4: a technical and biomechanical note for all-on-4 management of severe maxillary atrophy--report of 3 cases.
abstract: We present a technical note and 3 case reports of all-on-4 treatment of highly resorbed maxillas. The use of 4 angled implants, placed at as much as 30 degrees off axis, that engage the lateral nasal wall bone provide high torque fixation for immediate temporization. The technique is proposed as an alternative to sinus grafting and for use with multiple implants or zygomatic implants.
