Laser-assisted new attachment procedure (LANAP) is a surgical therapy for the treatment of periodontitis, intended to work through regeneration rather than resection. This therapy and the laser used to perform it have been in use since 1994. [citation needed] It was developed by Robert H. Gregg II [1] [2] and Delwin McCarthy.
A dental laser is a type of laser designed specifically for use in oral surgery or dentistry.. In the United States, the use of lasers on the gums was first approved by the Food and Drug Administration in the early 1990s, and use on hard tissue like teeth or the bone of the mandible gained approval in 1996.

The bone destruction patterns that occur as a result of periodontal disease generally take on characteristic forms. This X-ray film displays a horizontal defect . This X-ray film displays two lone-standing mandibular teeth, #21 and #22: the lower left first premolar and canine, exhibiting severe bone loss of 30-50%.
Sites with periodontitis exhibit clinical signs of gingival inflammation and loss of connective tissue attachment. Connective tissue attachment loss refers to the pathological detachment of collagen fibers from cemental surface with the concomitant apical migration of the junctional or pocket epithelium onto the root surface. [2]
Early bone loss may have occurred but is rarely evident radiographically. Grade II - There is a definite horizontal component to the bone loss between roots resulting in a probeable area, but sufficient bone still remains attached to the tooth (at the dome of the furcation) so that multiple areas of furcal bone loss, if present, do not communicate.
The rate of loss of attachment and bone loss is rapid. [19] Loss of attachment refers to the destruction of periodontium whereas the bone refers to the alveolar bone supporting the teeth. [23] The loss can be determined by using a calibrated periodontal probe and taking radiographs of the dentition. [24]
Photograph (left) and a radiograph (right) demonstrating extensive bone loss and soft tissue inflammation due to periodontitis. Plaque, calculus and staining. The defining feature of periodontitis is connective tissue attachment loss which may manifest as deepening of periodontal pockets, gingival recession, or both. This loss of support for ...
The tooth exhibits 50% bone loss, adding roughly 5-7 mm to the clinical crown of what is actually anatomical root. The fulcrum , existing somewhere immediately apical to the height of the bone, does not allow for any adjacent bone to avoid compression or tension, resulting in virtually complete widening of the PDL and a grim prognosis , due to ...
