Comparison of Nd Yag, Diode and Er:YAG Lasers vs Scalpel in Preprosthetic Vestibuloplasty: Vestibular Depth Gain

The patients were divided in 3 equal groups and the vestibuloplasty was performed by conventional surgery on the right side and by laser for the left side of the maxilla. The former served as a Control group. There were utilized three types of lasers and consequently divided the patients in three observational study groups: for Group 1, the vestibuloplasty was performed by Nd-YAG laser, for Group 2 a diode laser was utilized , while Group 3 was treated with an Er-YAG laser. An initial measurement of the vestibular depth was performed by using a millimeter markings William periodontal probe on three predetermined areas on each side: paramedian (next to the frenulum), antero-lateral (measured in the middle of the operated field), and lateral (at the most posterior place included in surgery). The measurements were performed 6 weeks postoperatively at the same levels as they were registered before surgery.
