Abstract
The use of microsurgical principles and procedures provides clinically relevant advantages over conventional macrosurgical concepts for plastic esthetic periodontal surgery. The term “periodontal microsurgery” proposed by Shanelec refers to a procedure that has advantages in periodontal surgery. The combination of an improved visual precision with the use of microsurgical tools specifically designed for this procedure allows more precise and less damaging manipulation of both soft and hard tissues and more capacity to properly debride the defect and the root surface, which increases the chances of healing by primary intention. Microsurgical procedures from incision to the final closure of the surgical wound have less extensive flap designs and enhanced vision fields that facilitate identification of defects and anatomical landmarks. Visual acuity is enhanced by both magnification and illumination when performing periodontal surgical procedures with the aid of an operating microscope (OM). Current evidence supports the benefits of OM and outcome superiority of periodontal surgical therapy with the use of OM for root coverage. It is not easy to move out of the comfort zone, especially when significant changes to the daily practice need to be implemented. This is one of the main reasons for limited use of microscopes in the periodontal field. Great determination, effort, and dedication are required to incorporate microscopy into practice; however, after it is accomplished, there is no turning back. Moreover, it takes clinical performance to a new level. The purpose of this chapter was to present the clinical experience with the use of the microscope in periodontal and peri-implant surgery.
