Upon tightening loop 52, the flexible or semi-flexible properties of retention strap 50 achieve a customized diameter reflective of the tooth's 100 outer surface 102 profile. For example, as the diameter of loop 52 is closed about outer surface 102, retention strap 50 conforms to positive features of outer surface 102, while spanning negative features.
