PURPOSE: The main objective of this study, involving 11 patients, is to share our experience on an integrated treatment modality, namely, the use of cellular therapy simultaneously with surgical reconstruction. Published works show that the implantation of monocytes in ischemic tissue enhances healing by providing neo-angiogenesis, a key mechanism in tissue regenerative processes. MATERIALS AND METHODS: Our approach included the utilization of autologous monocytes and endothelial precursor cells in the bone graft itself to improve the success rate of the integration of the bone graft and its long-term viability/survival by promoting angiogenesis...

PURPOSE: Immediate implant placement in conjunction with intentional root retention is a recently introduced technique, but the majority of existing documentation is limited to short-term reports with low level of evidence. Hence, the aim of this study was to document the long-term clinical and radiographic results of the root membrane technique. METHODS: This retrospective study reports on clinical results of the root membrane technique for periodontal ligament-mediated immediate implant placement with up to 10 years of follow-up from 3 private dental practices...

Bone augmentation is used to supplement bone defects during dental implant treatment. In this technique, the area filled with bone prosthetic material is covered with an artificial space-making device or titanium mesh sheet, which must be manually adapted to the bone defect during the procedure before being fixed in place. Selective laser melting (SLM) method can be used to preadapt the titanium mesh sheet based on preoperative CT data. This method enables shorter surgery times compared with conventional titanium mesh sheet methods, as well as regeneration of an ideal alveolar bone shape...
