Clinical Trial 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.

Intervention

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.
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.

Outcome

Type Measure Description Time frame Safety issue
Primary Osteotomy time The time from the start of the osteotomy to the luxation of the bone block was measured with the help of a digital stopwatch. Intraoperative
Secondary Change in pain Postoperative pain was assessed using a Visual Analogue Scale (VAS) ranging from the absence of pain (score 0) to the most severe pain imaginable 7 days
Secondary Change in Mouth opening The distance between the mesio-incisal corners of the upper and lower central incisors was measured with the help of a ruler when the mouth opening was at its maximum. 7 days
Secondary Change in Oral Health-related Quality of Life Evaluated by OHIP-14 14 days
Secondary Operation time The total time from the first incision of the operation site to the last suture was measured with the help of a digital stopwatch as the operation time. Intraoperative
Secondary Change in facial swelling With the technique described by Neupert ; Angle of mandible-tragus Angle of mandible-lateral canthus of eye Mandible corner-nose wing Angle of mandible oral-commissures Measurements were made with a tape measure from 5 points, with the mandible corner-pogonion. 7 days
