Void filling

**Void filling** refers to the process of filling empty spaces or gaps in materials or structures to enhance stability, strength, or aesthetics. In construction and manufacturing, void filling is crucial to prevent structural weaknesses, improve insulation, and avoid moisture accumulation. This term is also used in dentistry, where specialized materials fill cavities to restore tooth integrity. In digital contexts, void filling might refer to techniques that fill empty areas in design layouts or data sets.
