Autogenous Particles Harvesting During Implant Surgery

Status Not yet recruiting

Clinical Trial Summary

The aim was to compare the osteoblast activity and osteogenic potential of autogenous bone particles harvested using three different techniques, determine the most advantageous method of collecting autogenous bone particles. Bone particles were harvested during dental implant surgery using low-speed drilling and high speed drilling. After the osteoblasts were cultured, cell proliferation, migration, mineralization, transcription of osteogenesis-related genes, secretion of osteogenesis-related proteins, and osteoinductive protein content in the bone particle matrix were evaluated

Clinical Trial Description

A total of 60 individual dental implants will be placed in this study. Each patient will receive two dental implants (Spain), each measuring 10 mm in length and 4 mm in diameter, for the replacement of missing teeth in the right and left mandibular first molars. The surgery will be performed under local anesthesia (0.5% articaine with epinephrine) with the elevation of a mucoperiosteal flap. For the randomization of the implant osteotomy milling protocol in each hemimandible, an online randomization service (www.randomization.com) will be utilized. In each patient, the conventional high-speed milling protocol with irrigation using physiological saline will be employed in one hemimandible. In the other hemimandible, the implant osteotomy will be performed using a low-speed milling protocol without irrigation. The milling sequence for the conventional high-speed milling protocol with irrigation will be as follows: the osteotomy will be initiated with a 2.0 mm diameter marking drill, followed by a pilot drill of the same diameter. Subsequently, drills of 2.6/3.2/ and 3.6 mm diameters will be used consecutively. All drills will be used at a speed of 800 rpm and at a depth of 10 mm. On the other hand, the milling sequence for the low-speed milling protocol without irrigation will be the same, but all drills will be used at a speed of 50 rpm (at the same depth of 10 mm). Finally, once the dental implant and closing screw are inserted, the mucoperiosteal flap will be sutured with simple stitches using synthetic polyamide suture, without immediate prosthetic loading. In all cases, postoperative medication will include 500 mg/8 h amoxicillin for 7 days (in cases of penicillin allergy, 300 mg/8 h clindamycin for 7 days), and 600 mg/8 h ibuprofen for 3 days. ;
