Summary

The aim of this randomized prospective clinical trial was to evaluate the outcome of bone block harvesting from the retromolar region using the Conventional and Piezosurgery Method. The study was planned on 19 patients (13F,6M) on 31 donor sites. In patients with bilateral bone harvesting, the donor site and the surgical method to be used were determined by the randomization protocol, while in patients with bone harvesting from a single site, the donor site was determined by considering parameters such as proximity to the operation site and distance to the inferior alveolar nerve. Clinical parameters such as operation time, pain, swelling, trismus, nerve damage were evaluated.

Conditions

• Alveolar Bone Resorption

Interventions

Type	Name	Description
DEVICE	Bone harvesting from ramus area with piezosurgery for autogenous bone augmentation	In this invervention, the piezo-surgical device settings were set to irrigation: '4', function: 'cortical', light: 'auto'. After the full-thickness flap was lifted with the periosteal elevator, superior and vertical osteotomies were performed with the OT-12 piezo-surgical tip. Lower horizontal osteotomies were performed using OT8-L or OT-8-R piezo tips according to the studied quadrant, combining the vertical osteotomy.
DEVICE	Bone harvesting from ramus area with conventional burs for autogenous bone augmentation	In control group, After the full-thickness flap is lifted with the periosteal elevator, using a thin #9 fissure burand the surgical handpiece S-11 Straight tip , the physiodispenser settings are according to the manufacturer's recommendations. The osteotomy was performed after it was adjusted to 40,000 rpm as appropriate. Bone incisions were completed with a round bur to combine the lower horizontal osteotomies and 2 vertical osteotomies. The osteotomies were completed with the help of a thin flat drill, and the block graft was carefully separated from the donor site.
