Methods used for assessing stresses in buccomaxillary prostheses: photoelasticity, finite element technique, and extensometry.

The authors describe a literature revision on assessing stresses in buccomaxillary prostheses photoelasticity, finite element technique, and extensometry. They describe the techniques and the importance for use of each method in buccomaxillary prostheses with implants and the need of accomplishing more studies in this scarce literary area.
