Paper Abstract

40 patients with edentulous maxillary jaws were referred to our private practice limited to maxillofacial surgery, due to atrophy of the alveolar ridge. Before prosthetic renewal of the upper removable prosthesis the restorative dentist requested a sufficient vestibule. After supraperiostal preparation, soft tissue advancement and fixation with absorbable sutures. The recipient site was covered with a free gingival graft. Group I was operated on traditionally using a scalpel. In group II incision and soft tissue preparation was performed using a diode laser. Wavelength: 810 nm; Continuous wave mode; 400 micron optic fiber; Output power 1.6 Watt. All operations were performed by one surgeon experienced in both operation techniques. Every patient was followed-up 1, 4, 8 weeks, 6 and 12 months. The vestibular height directly adjacent to the nasal cavity and 2cm distal to these first measuring locations were taken. Each patient was asked to evaluate their individual discomfort and postoperative pain level. Both groups showed no significant difference in vestibular height after 1, 4, 8 weeks, 6 months and 1 year. The postoperative height of 1.28 cm was reduced to 0.84 cm after 1 year. Furthermore both groups showed uneventful healing and take of the free gingival grafts. The assessment of the pain and discomfort level by the patients brought a significant difference between both groups in favor of the laser assisted operation technique.
