Evaluation of Horizontal Ridge Augmentation Prior to Implant Placement Via Subperiosteal Tunneling Technique Using Two Bone Graft (Cerabone and Cenobone)

Evidence suggests a successful use of autogenous bone grafts with or without a collagen membrane for lateral ridge augmentation. In this regard, one of the approaches is the use of subperiosteal tunneling technique to produce tent effect after flap designing and placing the collagen membrane. With regard to the lack of sufficient data on this technique, more accurate studied are needed. Furthermore, limited studies are available and complications, as well as the chance of treatment failure must be investigated. This convenient method could be a viable alternative to open techniques if provided with reasonable success.
In this study, samples were among edentulous patients, who were candidate for implant and referred to School of Dentistry in Mashhad, Iran. The subjects were examined and their cone beam computed tomography (CBCT) was provided. In total, 10 patients with inadequate ridge width were enrolled in the study. Afterwards, subperiosteal tunneling technique was applied on the subjects using Cerabone or CenoBine for lateral augmentation treatment. The ridge width was evaluated after six months. Moreover, pain and swelling at the surgical site were evaluated at the first, suture removal and the last sessions. Data analysis was performed using one-sample t-test and two-way ANOVA.
T-test showed a significant increase in both group (Cerabone: 1.44±4.17, CenoBone: 0.64±1.25). The mean increase in Cerabone group was significantly higher than CenoBone group. No pain and swelling were observed.
According to the results, the increase rate of bone width after six months in the group was significantly higher in the Cerabone group, compared to the CenoBone group.
