Dental surgical procedures known as guided bone regeneration (GBR) and guided tissue regeneration (GTR) use barrier membranes to control the growth of new bone and gingival tissue at sites where there are insufficient amounts of bone or gingival tissue for proper function, aesthetics, or prosthetic restoration. Directed tissue regeneration normally refers to the repair of periodontal attachment; guided bone regeneration typically refers to ridge augmentation or bone regenerative therapies. Similar to direct tissue regeneration, guided bone regeneration concentrates on the development of both...

This book describes about a project on controlling the wheel chair using MEMS. The MEMS are fixed on the hand. Whenever the hand moves in a particular direction, the mechanical movement of the hand will be recognized by MEMS. MEMS converts this mechanical hand movement into equivalent electrical signals(X, Y, Z coordinates) and sends it to the microcontroller. Wheel chair has two D.C gear motors. These motors move in 2D direction with the help of the H-bridge. With the help of LEDs we can display status of wheel chair i.e forward, backward, left, right direction status.Micro electromechanical...
