The scope of use of strain gauges is constantly expanding.
Accelerated development of innovative technologies and technological progress in various industries made us look at tensometry in medicine in a new way.
Appointment
Tensometry is a diagnostic area that analyzes the values of minor elastic deformations of hard dental tissues under load. This method is used to determine the load on the chewing tooth surface, to analyze the distribution of forces between the bases and the bed. prostheses different structures.
Strain measurement is carried out gnatodynamometer. The advantage of the device lies in the measurement accuracy in a wide range (0-100 kg) and a slight separation of the bite. The device was proposed and tested in 1976.
How is it used
The strain gauge is inserted with stops between the tooth to be extracted and a pre-fixed notch in the base. The rotating steering wheel moves the legs of the apparatus apart, producing some pressure on the tooth being moved. The value of the indicator in kilograms is displayed on the indicator. After that, the element (s) are brought into an active state.
The gnatodynamometer measures the pressure produced by it. The physician records the data of the scale and vernier in the disease card for further control.
Indicators on strain gauge equipment on average vary between 15-35 for anterior teeth and 45-75 kg for molars.
Strain gauging makes it possible to reduce the number of visits to the dentist and reduce the duration of treatment.
Indications
The strain gauge method for measuring deformations can be assigned with the following indications:
- periodontal disease;
- periodontitis;
- partial loss of teeth;
- prosthetics and orthodontics;
- dentoalveolar deformities.
