INORGANIC, INJECTABLE AND THERMOSENSITIVE CEMENT FOR BONE RECONSTRUCTION: PREPARATION AND USE

摘要

Inorganic, injectable and thermosensitive cement for biomedical applications: preparation and use. The invention relates to the preparation of a thermosensitive, injectable cement with clinical applications in minimally invasive dentistry and bone surgery, based on self-setting mixtures of magnesium oxide, phosphates of calcium, sodium or ammonium, carbonates of calcium, and sulfates of calcium or other inorganic salts with a poloxamer hydrogel. The main property of this cement is a thermosensitive effect. The cement also has a high level of cohesion when it comes into contact with fluids at a physiological temperature, which is accompanied by a reduction in the effort required for the injection thereof, along with the temperature. The cement can be used for bone and dental applications, and also for filling bone defects. The cement is especially applicable in cases where a minimally invasive use may be necessary.
