A new implant for nasal reconstruction.
Extraoral implants have been used for many years to anchor silicone nasal prostheses. This report describes the design and use of a specially engineered bifunctional implant, which is placed via an intraoral approach, to simultaneously anchor nasal and oral prostheses for an edentulous patient who has undergone a complete rhinectomy. The bifunctional implant was designed and milled from commerc...
متن کاملLow-loss Saw Filters Using New Spudt Structures
The new SPUDT structures based on triple electrode sections (TES) per wavelength with the period between SAW sources about n/3 are presented. The simulation technique which accounts for second order effects has been developed within the framework of modified equivalent circuit model. The SPUDT structures have been implemented in filters with 0.1-3.2% bandwidths fabricated on quartz and LiTaO3 ...
متن کاملNew Metallization Concepts for High Power SAW Devices
Stress induced mass transport (acoustomigration) is the dominant failure mechanism in surface acoustic wave (SAW) devices. A strong microstructure damage of the metal finger electrodes by void and hillock formation results in an irreversible degradation of the electrical characteristics of the device. Copper based metallizations were applied to SAW technique using LiNbO3 and quartz substrates t...
متن کاملDESIGN AND STRUCTURE OF A NEW DEVICE FOR AUDITORY ELECTRICAL STIMULATION FOR SUPPRESSION OF TINNITUS
Auditory Electrical Stimulation for Tinnitus Suppression Tinnitus is the conscious experience of sound which arises in the head of its owner, but without a voluntary origin obvious to that person. About 10-15% of all adults report prolonged spontaneous tinnitus (PST). There are a lot of methods for suppressing this complaint. One of these methods is electrical stimulation. Electrical stimu...
متن کاملSpontaneously electrical solids in a new light.
Reflection-absorption infrared spectroscopy (RAIRS) of nitrous oxide (N2O) thin films is shown to provide an independent means of observing the spontelectric state, the first new structural phase of matter, with unique electrical properties, to have emerged in decades. The presence of a spontaneous and powerful static electric field within the film, the defining characteristic of spontelectric ...
