text: Yo, throughout the years, the meaning of implant failure's unclear,
  Some say it's all implants placed, others just ignore failures near.
  Stresses on bones of varying densities, from different prosthetic gear,
  And how we measure failures, gotta make that crystal clear.
  
  Check it, this paper drops knowledge on two methods we employ,
  To determine if implants survive, bringin' that dental joy.
  36 months of data, see which method's got the most clout,
  Supportin' various dental prostheses, we gonna figure it out.
