Blake and Bibby (1998) reviewed the orthodontic literature on
long-term retention and evaluated the stability of various treatment
modalities.Their recommendations, related to determining the final
tooth position are based on well documented studies and listed below:
1. The patient's pre-treatment lower arch form should be maintained
during orthodontic treatment as much as possible.
2. Original lower inter-canine width should be maintained as much
as possible because expansion of lower inter-canine width is prone to
orthodontic relapse
3. The most stable position of the lower incisor is its pre-treatment
position and advancing the lower incisors is correlated with
compromising stability
