We study a method for the implementation of a reliable teleportation protoc
ol (theoretically, 100% of success) of internal states in trapped ions. The
generation of the quantum channel (any of four Bell states) may be done re
specting technical limitations on individual addressing and without claimin
g the Lamb-Dicke regime. An adequate Bell analyzer, that transforms unitari
ly the Bell basis into a completely disentangled one, is considered. Probab
le sources of error and fidelity estimations of the teleportation process a
re studied. Finally, we discuss experimental issues, proposing a scenario i
n which the present scheme could be implemented.
