Abstract
The aim of this study was to analyze and compare the long-term clinical outcomes of
mature third molar autotransplantation in surgically created sockets and fresh extraction
sockets with regard to survival and functional success rates. A total of 65 third
molars with completely formed roots were autotransplanted in 60 patients (average
age 33.1 years). Thirty-six of the teeth were autotransplanted into surgically created
sockets with or without guided bone regeneration (GBR; delayed autotransplantation),
while 29 were autotransplanted into fresh extraction sockets (immediate autotransplantation;
control group). All patients underwent annual clinical and radiographic examinations
(average follow-up 9.9 years, range 7–13 years). The survival rates for the control,
GBR, and no GBR groups were 93.1%, 95.2%, and 80.0%, respectively, with no significant
differences among the groups. There were no statistically significant differences
among the groups with regard to the frequency of inflammatory root resorption or root
ankylosis. Age did not influence the clinical outcomes. These results suggest that
the autotransplantation of third molars with completely formed roots is effective
in both surgically created and fresh extraction sockets and provides a high long-term
success rate if cases are selected and treated appropriately.
