Brief summary
Evaluate the 10-year stability clinical, radiographic outcomes obtained with the application of the modified minimally invasive surgery to deep pockets associated with intrabony defects.
Detailed description
This 10-year follow-up of a randomized controlled clinical trial (Cortellini & Tonetti 2011) compares three treatment modalities in deep intrabony defects: i) a control group was treated with modified minimally invasive surgical technique alone (M-MIST, N=15); ii) a second group was treated with M-MIST combined with enamel matrix derivative (M-MIST EMD, N=15, Straumann, Switzerland); iii) a third group was treated with M-MIST+EMD plus Bone Mineral Derived Xenograph (M-MIST+EMD+BMDX, N=15, Geistlich, Switzerland) . The design of the original trial has been reported along with the one-year results and the details of randomization and allocation concealment (Cortellini & Tonetti 2011). Clinical outcomes of the three groups were longitudinally followed for 10 years. The 10-year follow-up was approved by the local ethical committee for clinical research of the Health Service of Tuscany (University Hospital of Firenze protocol ATRO2019, registration n° 15106\_oss). All patients gave informed consent to participate into the clinical trial.
