Hard tissue lasers have significantly improved the way several dental procedures are performed, providing a gentler and more precise alternative to traditional tools. These advanced devices use focused light energy to target specific areas of the tooth or bone, making them an excellent choice for treatments like cavity preparation, enamel shaping, and bone contouring.
There are two primary types of hard tissue lasers commonly used in dentistry: Er and Er,Cr lasers.
The Er
The Er (erbium-doped yttrium aluminum garnet) laser is known for its precision and efficiency in removing decayed tooth material and preparing cavities. Its specific wavelength is well absorbed by water, allowing for effective cutting of enamel and dentin with minimal heat production, which helps reduce the risk of thermal damage to surrounding tissues.
The Er,Cr
The Er,Cr (erbium, chromium-doped yttrium, scandium, gallium, garnet) laser is versatile, capable of working on both hard and soft tissues. This makes it an excellent choice for a range of procedures, from periodontal treatment to bone shaping. It provides a high degree of control and accuracy, which can enhance patient comfort and reduce recovery time.
Hard tissue lasers were first introduced in the 1980s and have since gained popularity as their technology and clinical applications have advanced. Today, they are a valuable addition to many dental practices, offering patients a more comfortable and efficient treatment experience with less need for anesthesia and faster healing times. As these technologies continue to develop, their role in dentistry is likely to expand even further, providing new possibilities for patient care and treatment outcomes.
