In a general practice for dental surgeons auto transplantations are done by an experienced dental surgeon. It is unsure whether treatment in this setting can compete with the results as described in literature. It is unknown which variables will influence the survival and success rates of these auto transplantations. The aim of this study is to investigate the prognosis of positioning auto transplanted premolars as agenetic premolars. This retrospective study investigated to what extent different variables such as gender, age, TAC, location of the donor and acceptor teeth, operation method, location of surgery and degree of root deformation influenced the survival and success rates of auto transplanted premolars to the position of agenetic premolars in a general practice for dental surgeons. All auto transplantations that were done recently (2012-2019), were registered in an electronic patient file (Epic); furthermore, the data were entered in an Excel file by the dental surgeon. In total, 81 auto transplantations were performed. Survival is defined as the presence of the auto transplanted teeth in the mouth at the moment of observation as the cumulative probability of survival over time according to Kaplan-Meier. For success, the following parameters were collected: signs of root deformation, obliteration, external root resorption, ankylosis, and whether endodontic treatment was necessary. These parameters were not influenced by time. The mean survival rate was 91,9% with a 95% CI [83,90;98,99]. After 2 years, the cumulative survival rate of an auto transplanted premolar in this population was 89,3% (se 4.4%). In 73% of the cases, the maximum success rate of 5 could be assigned to the treatment result. None of the variables turned out to be a significant predictor of the survival and success rates. In conclusion, this study shows that the prognosis of positioning auto transplanted premolars as agenetic premolars in a general practice for dental surgeons is exceptional. It was not possible to indicate factors that positively or negatively influenced the prognosis.
