[Clinical research progress in the treatment of intrabony defect by minimally invasive periodontal surgery]

Minimally invasive surgery develops rapidly in the periodontal treatments, especially in the periodontal regenerative treatment, in recent years. It supplements, to a certain extent, the insufficiency of the conventional periodontal regenerative treatment. The minimally invasive surgery has many advantages such as enhancing the healing process, reducing surgical chair time and minimizing patient discomfort, etc. It has been proved to improve the clinical effect and provide additional benefits compared to conventional approaches. At present, there are many studies on minimally invasive techniques used in tooth extraction or implant placement in China, but there are few reports on the application of periodontal minimally invasive surgical techniques. Thus based on the reviews of the literatures, this article describes the applications, advantages, indications, microsurgical instruments of minimally invasive periodontal surgery on the treatment of intrabony defect, including various minimally invasive surgical procedures. The review also demonstrates the therapeutic effects and research progress of minimally invasive periodontal surgery combined with biomaterials used in the treatments of intrabony defect. The present article may also provide reference for clinicians applying minimally invasive surgeries to treat intrabony defects.
