The authors report their experience with reference to wisdom tooth transplantation involving fifteen patients over a period of 6 years. They exclude from this paper those transplantations which they have done using buds without roots and those with teeth with completely formed roots, which would not appear to be the best time for transplantation from a physiological standpoint. They feel that the main indication occurs when (multi-ring orthodontic treatment being impossible) the first molar is impossible to preserve and the wisdom tooth cannot apparently become functional. They describe their techniques. Despite the successess obtained (11 cases out of 15) with a follow-up of 6 years to one and a half years, the authors express a degree of reserve as far as the distant future is concerned with regard to possible rhizoclasia.
