Angulated Implants: A Literature Review

Dr. Paulo Malo in 1993 advocated angulated placement of implants and named this concept as “All on four” in which two vertical implants are placed in anterior region and two implants in posterior region are placed at an angulation of 35-40 degrees [2]. Since then, several clinicians and researchers have reported use of angulated implants with varying degrees of success over a period of time but there is no consensus about the routine use of angulated implants for rehabilitation of patients with severely resorbed alveolar ridges
