Laser are a clean source of heating with a unique set of optical properties that allow a wide range of material processing method from more heating to synthesis of finished components. The major hurdles that restrict wider use of laser in routine material processing application are limitation of beam size with respect to the component size/dimension, high installation and replacement cost, additional and expensive accessories, and need for skilled manpower. However, the high productivity, precision and versatility of laser material processing can easily overcome the above limitation, if areas are identified where laser offers unmatched advantages in terms of end properties and product quality in comparison to those achieved by other conventional techniques. It is to conclude that laser is a useful tool in oral and maxillofacial surgery and in the other dental and many medical applications If used properly, with taking in consideration good understanding of laser principle and interaction between different laser parameters with biological tissue. This will enhance better operator performances with different laser treatment.
