Wizards or Step by Step Help

Is there a design pattern for Wizards or Step by Step help?

I have a dental imaging program that has different procedures such as 
"replace teeth", each procedure requires the user to do a series of
steps 
for example "Outline Teeth, press next when finished".  The Wizard or
Help 
Step would control the UI a little bit for example, it might select the 
selection tool automatically or open the teeth libary when the user finished 
selecting the teeth.

All this is already coded, its structured but hard to follow and I was 
thinking to recode it using the State pattern but I was wondering if there 
was already a wizard pattern.
