Resumen
Use of preformed solid matrices in the field of bone regeneration to achieve volume increases both horizontally and vertically. One of the drawbacks of current formulations is that the matrices are split due to the lack of rigidity when they are fixed by osteosynthesis screws to the maxillary bones. In this case, due to the lack of rigidity, we must add the poor resorption capacity of hydroxyapatite, which makes rapid remodeling of the bone difficult. In an attempt to solve the problems previously presented, the use of more rigid and perforated synthetic blocks for their screwing in bone regeneration procedures has been studied. The idea of designing already perforated blocks for the entry of an osteosynthesis screw at the moment of realization reduces the possibility of fracture of the material that usually occurs when drilling with cutters, facilitating the technique. We consider this solution as a real alternative to the use of antologous bone blocks. (Machine-translation by Google Translate, not legally binding)
