Composites, particularly in dentistry (e.g., dental composites), are typically retained by the phenomenon of mechanical interlocking. This process involves creating microscopic irregularities on the surface of a material (like a tooth) and then flowing a bonding agent or composite material into these spaces, which then hardens.

Widened periodontal ligament space is NOT a positive bone factor. It indicates pathology such as orthodontic movement, trauma, or periodontal disease. Positive bone factors include heavy cortical bone layer (provides strength), dense lamina dura (indicates healthy bone), and normal bone height (adequate support). Widened PDL space suggests compromised support.
