APPLICATION OF ADVANCED PRODUCTION METROLOGY FOR QUALITY IMPROVEMENTS IN BIOMEDICAL ENGINEERING - ANALYSIS AND EVALUATION OF SURFACE STRUCTURES OF DENTAL IMPLANTS

摘要

Rapid development in biomedical engineering demands the application of modern computerized measurement techniques and utilization of measuring devices with new technologies. Computer aided co-ordinate measuring technique can be particularly applied to evaluate the shape of non-technical structures with high accuracy. Measurement results create the basis for the improvement and optimization of future work in biomedical techniques and related areas. There are numerous important characteristics that describe the implant quality required for a successful implant. Besides defining the macroscopic structure like material and shape, an implant should reach defined microscopic structure such as the chemical, physical, mechanical, and topographic characteristics of the implant surface. These different characteristics describe the effect activity of the attached cells that are in close proximity to the medical implant surface. By using initially developed advanced measurement techniques for engineering applications, the clinicians could be able to characterize biomedical surfaces to assist in their maintenance, modification, optimisation and trauma repair. With development of robust measurement tools of sophisticated production metrology and best practice protocols it will be possible to quantify the appropriate metrology so that it will be possible to improve the medical product and process quality and to provide assurance feedback to the clinicians to assure good practice, functional achievement and long service life of the restoration, implantation object.
