Stress and strain patterns of 1-piece and 2-piece implant systems in bone: a 3-dimensional finite element analysis.

Statement Of Problem: The transition from implant to abutment is solid in 1-piece (1P) and broken in 2-piece (2P) implant designs. This difference may affect occlusal load distribution and marginal bone response.

Purpose: To determine whether 1P and 2P implants with equivalent geometries exhibited stresses and strains differently under applied loading conditions.
