Abstract

This study evaluated whether there is a difference between a conventional titanium distraction device and a TiN-coated device in terms of implant osseointegration after horizontal distraction osteogenesis in narrow alveolar bone. Four adult mongrel dogs, each weighing 9-10 kg, were used in this study. The lower premolars were extracted and horizontal distraction was performed with conventional titanium distraction devices (group 1) or TiN-coated devices (group 2). After an 8-week consolidation period, the implants were installed, and the dogs were sacrificed after another 8 weeks. The osseointegration around the implants was evaluated histomorphologically. There was one failure in experimental group 1 because of fracture of the device. Direct bone contact was achieved and there were no significant differences between the control group and experimental groups 1 and 2 in terms of osseointegration around the implants at 8 weeks. In summary, intraoral distraction osteogenesis is a good option for augmenting severely atrophied alveolar ridges, and the TiN-coated device may be useful because of its advantages, which include surface hardness, corrosion resistance, and reduced bacteria.
