Introduction:
This study aimed to describe the fabrication, implementation and evaluation of 3D-printed patient-specific models for unskilled students to enhance learning in immediate implant procedures and provisionalization.
Materials And Methods:
The individualized simulation models were designed and processed based on CT and digital intraoral scanning of a patient. Thirty students performed simulation implant surgery and provisionalized the implant sites on the models and answered questionnaires to assess their perceptions before and after the training. The scores of the questionnaires were analysed using the Wilcoxon signed-rank test.
Results:
Significant differences before and after training were found in the students' responses. Students reported better results in understanding of surgical procedures, knowledge in prosthetically driven implantology, understanding of minimally invasive tooth extraction, confirming the accuracy of surgical template, usage of the guide rings and usage of the surgical cassette after simulation training. The overall expenditure on the simulation training involving 30 students amounted to 342.5 USD.
Conclusions:
The patient-specific and cost-efficient 3D printed models are helpful for students to improve theoretical knowledge and practical skills. Such individualized simulation models have promising application prospects.
