Clinical evaluation of Laser-Assisted New Attachment Procedure(®) (LANAP(®)) surgical treatment of chronic periodontitis: a retrospective case series of 1-year results in 22 consecutive patients

PURPOSE: Treatment for periodontitis has evolved over the years as new technologies have become available. Currently, lasers seem attractive as a treatment modality, but their effectiveness needs to be verified. The purpose of this project was to evaluate Laser Assisted New Attachment Procedure(®) (LANAP(®)) surgery as a single treatment modality. METHODS: As part of a mandatory training program for periodontists and other dentists, 22 consecutive patients diagnosed with moderate to severe periodontitis (probing depth [PD] up to 11 mm) were treated with the LANAP(®) surgical approach using a 1064-nm Nd:YAG laser as part of a multi-step protocol. Following single-session active therapy, they were entered into a maintenance program. Their clinical status was re-evaluated at 12–18 months following surgery. RESULTS: All 22 patients completed the 12- to 18-month follow-up. PD, clinical attachment level, and furcation (FURC) showed substantial improvement. Recession was minimal (mean, 0.1 mm), while 93.5% of PD measurements were 3 mm or less at re-evaluation. Furthermore, 40% of grade 2 FURC closed clinically. CONCLUSIONS: Within the limits of this case series, LANAP(®) was found to be an effective, minimally invasive, laser surgical therapy for moderate to advanced periodontitis.
