简要总结
The aim of this study was to compare the clinical results obtained using the conventional approach versus the modern laser method, by recording postoperative results
详细描述
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.

研究组 & 干预措施
Nd -YAG vestibuloplasty group
12 patients treated for Group 1 using a Nd-YAG laser on the left side of the maxilla. The procedure was performed under local anesthesia to ensure patient comfort and cooperation. The parameters for the Nd-YAG laser (Lightwalke, Fotona, Slovenia) that was utilized for this procedure were: center wavelength of 1064 nm, output power of 4 W, frequency equal to 25 Hz, Micro Short Pulse (MSP) mode, sapphire fiber of 300 micrometers in diameter, power density equal to 6229 W/cm2.
The right side was treated conventional using the scalpel. Clark's vestibuloplasty method was applied in all conventionally operated right sides of the patients
干预措施: vestibuloplasty for Nd-YAG group (Procedure)
Diode laser vestibuloplasty group
12 patients treated for Group 2 where a diode laser was utilized. for performing the left side of the maxilla. we utilized the Epic X TM laser from Biolase, with a center wavelength of 940 nm and a pre-initiated tip, in a contact, continuous mode, with an output energy of 3 W. Surgery with the laser tip began at the mucogingival junction with a horizontal movement directing the laser parallel to the bone, and thus slowly releasing the muscle fibers towards the new vestibule depth. The right side of the maxilla was performed by conventional surgery using Clark s method.

Er-YAG laservestibuloplasty group
12 patients treated for Group 3 where an Er-YAG laser was utilized to treat the left side of the maxilla. The Er-YAG laser (Lightwalker, Fotona, Slovenia) was equipped with a H14 handpiece, characterized by the following parameters: center wavelength of 2940 nm, contact mode, long pulse, energy of 200 mJ, frequency equal to 20 Hz, power of 4 W, water 2, gas 2. The right side of the maxilla was performed by conventional surgery using Clark s method

结局指标
主要结局
pain and comfort
时间窗: days 1, 3, and 7 postoperatively
Pain and discomfort values were compared between the conventional surgery and the Nd:YAG laser, diode laser, and Er-YAG laser groups by using the Wilcoxon signed-rank test. The laser-treated sides have shown statistically significant reductions in both pain and discomfort scores at all considered timepoints (p \< 0.05), as presented in the following.
The vestibular gain depth
时间窗: 6 weeks
Vestibular depth measurements were compared between the initial, the immediate postoperatively, and the 6-week postoperatively timepoints. Paired sample t-tests or Wilcoxon tests were utilized, depending on distribution, to evaluate changes within each technique (i.e., conventional and lasers).
