Abstract

The optimal distribution of stress and preservation of bone in implant-supported prostheses remain critical factors affecting the long-term success of full-arch rehabilitations. Therefore, it is of interest to compare the stress distribution and clinical outcomes of the All-on-Four versus All-on-Six prosthetic concepts in full-arch rehabilitation. Hence, a total of 200 participants were divided into two groups, with 100 participants receiving All-on-Four and 100 receiving All-on-Six implants. This study advances knowledge by providing empirical evidence that the All-on-Six prosthetic concept offers better stress distribution, bone preservation and implant stability.
