![]() During the application of pressure, the diaphragm component to the piezoelectric sensor displaces the connecting rod. ![]() Mechanical sensors are made of a sensing element known as a diaphragm, a rod, a three-terminal resistor that acts as a voltage divider, and a direct current voltage source. There are two types of pressure sensors (mechanical and electrical) that are typically used to measure the piezoelectric effect. Piezoelectric crystals such as barium titanate and ceramic materials such as lead zirconate titanate are considered smart materials for the purpose of generating a piezoelectric effect and are built-in piezoelectric sensor technology. Functional PrincipleĪ piezoelectric effect is detected by a sensor and from this detection, measurements can be made on changes in pressure, acceleration, and force – displayed in the form of an electrical charge. The video below animates the movement of a piezoelectric disk that can generate a voltage. When applying an electrical force to the crystal structure, the cells in this lattice change dimensions. With a change in pressure being the main stimulus to creating a charge in the crystal material, the piezoelectric effect can be reversed as soon as the pressure is lifted. This led to an understanding of the concept of piezoelectricity, or the accumulation of an electrical charge in crystals from applied stress.Īccumulation of an electrical charge as a result of a change in the state of pressure is a type of electromechanical interaction. ![]() The discovery came from experiments that measured an electrical charge on a layer of crystals (e.g., tourmaline, quartz, topaz, and cane sugar) after subjecting these crystals to mechanical stress. Safety - Piezosurgery techniques are extremely safe.The functional properties of piezoelectric materials were discovered in the 1880s by brothers Pierre and Jacques Curie.Not only will you heal faster than with traditional surgery, but you will experience minimal post‑operative pain or discomfort. Healing Time - Healing time is accelerated when piezosurgery technology is used.The procedures completed with piezosurgery technology result in minimal bleeding and swelling, and reduced pain. Comfort - If you fear the trauma associated with drills and burs, piezosurgery eliminates this problem as well.In traditional surgery, there is great risk of damaging this precious tissue, but with piezosurgery, the system is so accurate and specific to the surgery site that this risk is eliminated. Accuracy - Hard tissue is surrounded by soft tissue including arteries, nerves, and sinus membranes.Pechak is able to perform procedures such as tooth extractions, crown lengthening, ridge expansion, periodontal therapy, and implant site preparation with increased accuracy and minimal discomfort. ![]() Whereas traditional methods of bone-cutting, such as drills and burs, result in some tissue and bone loss regardless of the dentist’s precision, piezosurgery technology eliminates this risk. The piezosurgery system uses ultrasound waves to cut bone without damaging soft tissue. Pechak utilizes advanced technology to make your dental surgery more effective and comfortable for you. Since it will not injure soft tissues such as gum and nerves, it is a wonderful minimally invasive option to tooth removal.ĭr. This technology is the safest means in which to remove a tooth, hidden or damaged root tips from a previous extraction done elsewhere, to prepare bone grafts and sites for dental implants. The Piezotome® essentially vibrates at a high frequency which does not effect or damage the soft tissue, leaving the delicate gum tissue and surrounding nerves unharmed while using sterile saline to cool the area and remodel the bone. Pechak is using this innovative technology in lieu of the “drill” to make extremely precise and very gentle, minimally invasive incisions into bone. Piezoelectric technology has become the treatment of choice for delicate surgical bone grafting procedures.
