AIM: Autotransplantation of teeth (ATT) is a viable biological method for addressing dental defects. The objective was to achieve occlusal reconstruction-orientated ATT to enhance functionality and obtain optimal location and adjacency. This study proposes a new concept of a guide (a fully guided system) to achieve position-predictable ATT. METHODOLOGY: This study included 30 transplants in 29 patients who were randomly divided into two groups during the initial examination using a single-blind method. The experimental group comprised 15 transplants in 14 patients who underwent surgery using a fully guided system. Fifteen transplants were performed on 15 patients in the control group using only a replica. RESULTS: The mean number of repeated teeth autotransplantation attempts and mean preparation time exhibited no significant differences. The mean follow-up period was 1 year. Twenty-six transplants were followed up clinically, while four were only followed up by phone calls. The experimental group demonstrated a 100% success rate, whereas the control group exhibited a 70% success rate, with an overall 100% survival rate. 3D analysis: Deviation of both angle and distance was calculated for evaluation of accuracy. The mean centre deviation of teeth in experiment group was 0.79 mm (95% confidence interval [CI], 0.51-1.08) compared to 1.79 mm (95% CI, 1.10-2.47) in control group (p < .05). The mean of average index points distance deviation showed a significant difference. The me...
