MEMS plays a vital role in manufacturing several electronic devices.It has a wide application in electronics manufacturing field.The fabrication of MEMS is very popular because of its miniature size,capacity power,sensitivity,etc. MEMS fabrication is possible even at high resonant frequency devices which can be operated at regular frequencies and greater bandwidths.Simulation is done using COMSOL multiphysics software.A surface capacitive pressure sensor has been simulated using different materials.The capacitance is analysed and the graphs are plotted.

An implant supported crown or a conventional fpd is the most common treatment for the replacement of maxillary anterior teeth. The maxillary anterior region claims both esthetic and functional rehabilitation. The important factors involved in the replacement are - bone in the edentulous area, occlusal function, systemic conditions, socioeconomic status and willingness of the patients.The aim of this study was to assess the prevalence of tme duration for esthetic zone replacement after extraction. The study was conducted as a retrospective university-based study. Data of patients who underwent fpd treatment in maxillary anterior region was collected and analysed using SPSS software and the results were obtained. Chi square test was used to find the association between groups.The frequency rate of replacement of maxillary anterior was highest in the age group between 26 - 45 years (63.4 %). The frequency of replacement was higher in males (59.7 %) than in females. Most of the replacements were done at 2 months time interval. However, no statistically significant association was found between the groups.
