Application Of 3D Graphics Technology In Oral Anatomy Practical Teaching In Secongdary Vocational Schools

3D technology,with its vivid simulation scenarios and powerful interactive ability has an irreplaceable positive role in creating simulation learning scene for learners,and is a hot issue in research of computer technology.The research object of this paper is the current popular 3D graphics technology.Current 3D graphics technology is mainly used in the field of film,television,games and other entertainment,this paper is focused on its application in the course of teaching.Graphics are including 2D and 3D graphics technology.Three-dimensional is also called 3D graphics,in addition to the content there are the level of the X axial and vertical Y axis,also Z axis of the space,so that is called 3D,and 2D is the difference between the 3D graphics information can contain 360 degrees,can from different angles to performance.Because of its highlight stereo feeling close to reality and lighting effects,it has created favorable conditions for the popularization and application of oral anatomy of secondary vocational school.According to the current situation of vocational training of oral anatomy teaching,analyzes the characteristics of vocational oral anatomy teaching,combined with the characteristics of 3D graphics technology expounds the positive significance of introducing 3D graphics technology in morphology teaching.The basic viewpoints of cognitive learning theory,imitation learning theory and operation skill learning are analyzed,and the inspiration to this study is also serves as the theoretical basis for this study.The occupation school of Shandong Province health and to participate in the national oral skills competition occupation schools as investigation object,investigation and analysis of the application of 3D graphics technology at present in the professional dental technology in teaching,the survey results show that the 3D graphics technology in the teaching application is not widespread,mainly applied in practical teaching and training.This paper analyaes the problems and limitations of the application of 3D graphics technology in teaching,and puts forward the corresponding solutions from two aspects of the hardware construction and teaching methods.The main cotent of the research on vocational training of oral antomy part of the tooth carving as an example,the 3D graphics technology is applied to the oral anatomy practice teaching,shows the teaching methods,and the practical effect of comparative analysis.The practical results show that the application of 3D graphics technology,which makes up the inadequacy of teaching resources,improve the students' spatial imagination ability,improve the training effect,and get good grades in the oral skills competition,improve the quality of teaching.
