简要总结
This is a prospective study in which surgical extrusion of single-rooted teeth is carried out by the same operator in 15 consecutive patients.
Main objective: to evaluate the soft tissue rebound of the teeth 1 year after the surgery.
Null hypothesis (H0): surgical extrusion is not a predictable treatment for the restoration of single rooted teeth.
