Condition: Socket Preservation · Implant-supported Single Crowns · Hyaluronic Acid · Sponsor: University of Parma
The aim of this study is to test the use of a bovine-derived bone graft combined with a polynucleotides-rich hyaluronic acid (PNHA) gel for the preservation of the bone after a tooth extraction (alveolar ridge preservation) and to test the performance of a fully-digital workflow to rehabilitate the site with a dental implant. 40 patients in need for a single tooth extraction will be recruited at Centro di Odontoiatria, Università di Parma and they will be randomly assigned to 2 groups: extraction and spontaneous healing or extraction and regeneration of the site with a bovine-derived bone graft combined with a PNHA gel. At 4 months after extraction an implant will be placed in the extraction site, which will be rehabilitated with a fully-digital workflow and patients will be followed up at up to 12 months post rehabilitation. Two 3D x-rays with a small field of view will be performed immediately after extraction and at 4 months post extraction to plan implant placement. These images will also be used to assess changes in the dimension of the post extraction bone (primary outcome). As part of the study different questionnaires will be administered to assess quality of life and perception of the therapy and the wound exudate in the area of the extraction will be collected non invasively with a collagen sponge to assess the expression of different proteins during the early healing days. On the day of implant placement a sample of bone tissue will also be collected as part of the…
