Background Peri-implant bone stresses can sometimes be detrimental. Efforts are made in order to keep these stresses at the normal level.
Methods A finite element analysis was carried out in which two models were compared, the rigid attachment used in a fixed prosthesis versus the nonrigid one used in a removable prosthesis. Both of them were completely implant-supported.
Results Have shown that the rigid type produced higher stresses than the nonrigid one.
Conclusion Nonrigid attachments are more biocompatible than the rigid attachments.
