Laser-assisted new attachment procedure
（重定向自LANAP）
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. It was developed by Robert H. Gregg II and Delwin McCarthy. There is little evidence to support this technique over traditional therapies.
