RESUMO
Three kinds of biomedical materials of stomatology were introduced,including metal materials,polymers and non-metal bio composites.The literatures related to stomatology biomedical materials from 2008 to 2015 were collected in PubMed medical literature retrieval service system,and then statistical method was used to analyze the literature number,the numbers of literatures on different materials as well as the nations distribution.Composite,intelligent and functional materials were pointed out to be taking the place of metal materials,and thus might extend their clinical application in the future.
RESUMO
Objective To discuss the accuracy of 3DSS three-dimensional scanning system, which was used to reconstruct the 3D digital model of unilateral orbital defect patients. Methods By using 3DSS spectrometer on the case of patients with unilateral orbital defect, the related scan dates of facial structure were collected, and the reconstructed digital models were processed wax pattern by SLS prototyping machine. Results The digital solid model of three-dimensional reconstruction was smooth and complete, and border over the natural. The designed resin prosthesis can be inosculated with the orbital defect tightly and symmetrically. Conclusion To adopt the system can be successfully completed unilateral orbital defect restoration design and production, and ultimately satisfied the clinical requirement of prosthesis production.
