Brush your teeth with the help of regular toothpaste was not enough. Teeth require more intensive care and professional. Especially for sensitive teeth or already suffered damage, care should be more intense again. At least once every six months to the dentist examined the teeth. Patients should also consult the dentist before the tooth trouble. Unfortunately, most people will just go to the doctor when feeling a toothache. Not uncommon for people to feel afraid to check his teeth to the dentist. In fact, the delay in treatment can cause more serious illness. One of the reasons people feel very nervous and even afraid to check the tooth to the dentist because of dental appliances that seem "creepy". Therefore, plans for the ergonomic dental chair as one of the main part of the dental unit becomes a primary consideration of the medical device technology engineers.
Dental chair designs that are tailored to the size and shape of the human body is expected to provide comfort and reduce the fear of the patient when performing dental care. A model of the dental chair can be adjusted up and down position or upright and resting will provide comfort not only for patients but also physicians. "Thus, patients can obtain a position most comfortable to sit and lie down. While doctors can perform comfortably as well, "said Ariyanto, D3 student, Department of Mechanical Engineering Institute of Technology (ITS), Surabaya, which became one of the engineers dental chair.
Propulsion system of the dental chair using hydraulic systems, pneumatic, and electric motors. Dental chair in principle to implement hydraulic system utilizing Pascal's law. How it works similar to a hydraulic jack. When the pedal or lever is depressed or crushed by the dentist, the fluid pressure in the vessel-related will be forwarded to the chair seat so that the patient gets an upward force. The pneumatic system is a power transfer system that utilizes compressed air as working fluid. While the electric motor system uses gear or gear that are strung with electrical systems, either alternating current (AC) or direct current (DC). Gear that has a major role to reduce or increase the function rounds to raise and lower the dental chair.
An important part of a dental unit that requires is a good arrangement with dental tools that are usually located near the table where the appliance (bracket table). The simplest dental unit generally only have a player hand piece, air spray, cup holder, and the patient's mouth (spittoon unit), as well as a spotlight. Dental chairs by students of ITS is also equipped for low-speed hand piece and the height, wind sprays, spot reading rongent photo (intra oral movie viewer), where glass and place the patient, spotlights, as well as intra-oral camera is connected to the LCD.
