Last updated 2026-03-10

No results posted yet for this study

Summary

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

Conditions

  • Edentulous; Alveolar Process, Atrophy
  • Healthy Adult Participants
  • Edentulous Alveolar Ridge With Labial Resorption

Interventions

PROCEDURE

vestibuloplasty for Nd-YAG group

For patients treated by Nd-YAG laser, the procedure was performed under local anesthesia . The parameters for the Nd-YAG laser are: 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. Conventional vestibuloplasty was applied on the right side of the maxilla using Clark's method. A horizontal incision was performed at the mucogingival junction. The supraperiosteal dissection is performed and the muscles insertions were gradually dissected in an apical direction up to the desired vestibular depth. The mucosa of the inner side of the lip was undermined and the pedicled mucosal flap was secured to the periosteum at the new vestibule depth by using a 4-0 absorbable suture . The wound healed by second intention without any additional graft.

PROCEDURE

diode vestibuloplasty

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. Ablation 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 treated by conventional vestibuloplasty, Clark s method

PROCEDURE

Er-YAG laser vestibuloplasty

For the left side of the maxilla, we utilized an Er-YAG laser (Lightwalker, Fotona, Slovenia) 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. For the right side of the maxilla we applied conventional vestibuloplasty using Clark s method.
