Dental Augmentation
Defect augmentation is a common procedure used in reconstructive dentistry. In this, bone replacement material is used in building up bone to correct bone deformities. These bone deformities can be caused due to various reasons. One of the common occurrences which require dental augmentation is the formation of large cysts in the jaw line. In cases of smaller cysts, after the cyst is removed, blood fills in to the cavity and gradually turns into bone. However, in case of larger cysts, this transformation of blood to bone does not take place because sometimes, the blood shrinks to such an extent that it no longer has any contact with the bone and the cavity is not filled up. This bone-less cavity results in acute pain and also prevents the execution of successful implants. Thus, during the removal of large cysts, the dentist also conducts defect augmentation, in which he fills the erstwhile cyst cavity with bone reconstructive material to help in building up bone after the surgery. Bone augmentation or dental augmentation is also used in cases of acute perodontisis, which has resulted in the erosion of the jaw bone. This isolated bone-less cavity is filled with bone replacement material and the overlying membrane is stitched back in place. Over a period of six to eight months, the cavity is filled up and the defect augmentation is complete.

Lack of bony regrowth can also be caused by ingrowth of soft tissue into a bony cavity/defect because the soft tissue many times heals at an accelerated rate vs. the formation of bone. Guided Tissue Regeneration, uses dissolvable membranes/covers to allow bone to fill completely and keep Soft tissue out. Steven Koos DDS, MD
