选择性激光熔附技术制作上颌全口义齿金属基板的实验研究
The research of fabricating the complete denture base by selective laser melting technique
摘要
Abstract
Objective:The present study was to use the selective laser melting(SLM)technique in fabricating the complete denture base and to evaluate the feasibility of its clinical application.Methods:Twenty pairs of edentulous casts were divided into 2 groups randomly and equally, either by SLM technique, or by conventional method.The base-cast sets were transversally sectioned into 3 sections at the distal of canines,mesial of first molars,and the posterior palatal zone.The gap between the metal base and cast was measured in the 3 sections.Take use of stereoscopic microscope 50 times to measure the gap and analysis the record with SPSS statistical software.Results:The clearance value of SLM technique group was (114.42 ±49.90) μm~(234.58 ±130.89)μm,and(116.62 ±39.49)μm ~(173.94 ±115.17)μm in conventional method group.There was no statistical difference among the 3 sections both in SLM technique group and that in conventional method group(P>0.05).At the region of canines,the clearance value of SLM technique group was larger than that in con-ventional method group(P<0.05).At the mesial of first molars region and the posterior palatal zone,there was no statistical difference between the gaps in the two groups( P>0.05).Conclusion:SLM technique showed initial feasibility to manufac-ture the dental base of complete denture.关键词
