This thesis treats the development of packaging and integration methods for the cost-efficient encapsulation and packaging of microelectromechanical (MEMS) devices. The packaging of MEMS devices is often more costly than the device itself, partly because the packaging can be crucial for the performance of the device. For devices which contain liquids or needs to be enclosed in a vacuum, the pac...

introduction: the aim of this in vitro study was to compare polymicrobial microleakage of calcium enriched mixture (cem) cement, mineral trioxide aggregate (mta), amalgam, and composite resin as intra-orifice sealing materials. materials and methods: seventy single-rooted mandibular premolars were instrumented and obturated by cold lateral compaction technique. the teeth were randomly divided i...

introduction: the purpose of this study was to compare the sealability of three different commercial types of mineral trioxide aggregate (mta) and calcium enrichment mixture (cem) cement as an experimental root-end filling material. materials and methods: forty-six single rooted teeth were cleaned, shaped, and obturated. the apical 3 mm of each root was resected and root-end cavities with 3 mm ...

BACKGROUND The present study was aimed to evaluate and compare the apical sealing ability of two endodontic root-end filling materials namely, iRoot SP (ceramic based) and ProRoot MTA using the bacterial leakage system. MATERIAL AND METHODS A total of fifty recently extracted, single rooted teeth with a single straight canal were selected for the study. The teeth were chemo mechanically prepa...

Zero-level packaging technology ensures dicing and handling compatibility of the MEMS device along with low cost by encapsulating the MEMS components using wafer level processing. It is also essential for providing the MEMS with a controlled ambient in a cost-effective way. In order to be compatible with a broad range of MEMS processes, IMEC developed sealing methods with a low temperature budg...

PURPOSE The purpose of this study was to compare the sealing ability of temporary restorative materials at 24 hrs and 1 week. MATERIALS AND METHODS Endodontic access cavities were prepared in 56 extracted lower incisor-teeth and divided into 5 groups (n=10). Standard 5 mm deep access preparations were completed and root canals were prepared to size ISO #30 file. The access cavities were resto...
