卒後臨床研修におけるインプラント治療に関する調査

Objective: Implant therapeutics is a field of comprehensive dentistry requiring various dental knowledge, techniques, and experience. Although it is currently taught as an undergraduate program in many educational institutions, its content varies. Postgraduate clinical training should incorporate this program. We conducted an attitude survey on implant treatment training involving residents to promote the program and provide residents with appropriate knowledge and understanding of implant treatment. Methods: All 134 postgraduate residents between 2006 and 2011 at Kanagawa Dental University Yokohama Clinic participated in this study. On the first day, a lecture was given on implant surgery, and the subjects watched a video on implant surgery and a live operation using a monitor television. Implantation procedures were explained, implantation procedures were practiced using defect models, and individual trays were produced using implantation models. On the second day, a lecture was given on implant prosthetics, and impression-taking using the open- and closed-tray methods was performed using the individual trays. The questionnaire consisted of 15 items, including the degree of difficulty, necessity, and introduction of implant treatment, as well as opinions, selection reasons, and impressions. Questionnaires were filled in before and after the training, and statistical analysis was performed using the Wilcoxon rank sum test. Results: Regarding the question “What do you think of implant treatment compared to partial dentures and bridges?”, subjects answered that implant treatment was better than bridges requiring tooth grinding after the training. To the question “Would you recommend implant treatment to your family?”, the number of subjects who answered “yes” increased after the training. When asked “Is implant treatment more difficult than other treatment methods?”, the number of subjects who answered “yes” decreased after the training. To the question “If patients ask, can you explain about implants?”, the number of subjects who answered “yes” increased after the training.All subjects answered “yes” to “Is this training necessary?”. The question on time allocation revealed that the training time was short. Significant differences were observed between before and after training, which revealed that further education on implant therapeutics for postgraduate residents is needed. Conclusions: The number of residents who could explain implant treatment increased after the training; however, the influence of undergraduate education in recent years was reflected in these results. A systematic educational program that connects enrichment of the core curriculum in undergraduate education with postgraduate clinical training is needed. Our aim is to conduct further training including observation of treatment at our single training institution to maximize educational effects.
