Clinical Performance of Dental Implants with a Moderately Rough (TiUnite) Surface: A Meta Analysis of Prospective Clinical Studies.
PURPOSE A moderately rough anodized titanium implant surface (TiUnite) was introduced in 2000. This review and meta analysis aimed to assess implant survival and marginal bone level (MBL) changes documented in the literature. MATERIALS AND METHODS Repeated literature searches on dental implants were conducted, with the final search on October 7, 2016. The inclusion criteria were: prospective study, minimum of 20 patients, at least 12 months follow up postloading, and TiUnite implant survival reported. Regression analysis was performed on implant survival and MBL change from implant surgery. Peri implantitis as defined by the primary authors was reported at the patient level. RESULTS One hundred six out of 32,519 publications on dental implants met the inclusion criteria. Implant survival rates at 1 year were 99.50% at the implant level and 99.12% at the patient level, and survival rates at 10 years were 95.14% at the implant level and 91.50% at the patient level. Mean MBL change at 1 year was 0.409 mm at the implant level and 0.413 mm at the patient level, and at 5 years, it was 0.886 mm at the implant level and 1.029 mm at the patient level. Nineteen studies (18% specifically reported peri implantitis in 64 out of 1,229 patients with a mean follow up of 47.89 months, indicating a prevalence of 5.20% at the patient level. CONCLUSION Based on a meta analysis of prospective studies, implants with the TiUnite surface provide a predictable treatment modality in a variety of indications.
