The dental implant acts as a replacement for the root of a missing tooth. In turn, this artificial tooth root serves to hold a replacement tooth or bridge. Having a dental implant fused to the jawbone is the closest thing to mimicking a natural tooth because it stands on its own without affecting the nearby teeth and has great stability.
Oxygen sensor. An oxygen sensor (or lambda sensor) is an electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analysed. It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Dr. GÃ¼nter Bauman.
Another symptom of a potential exhaust leak is a failed emissions test. A leak not only lets exhaust gas out, it also allows oxygen to enter the exhaust stream, which can be detected during an emissions test. You will usually be required to make repairs before retesting, so have the leak checked and repaired.n Oxygen Sensor is located in the exhaust system at one or more points. An oxygen sensor converts the status of the engine's air/fuel mixture into a corresponding voltage signal. The oxygen sensor is sometimes referred to as a Lambda sensor on some European cars.
