The 3B Scientific A29/3 is a one-piece adult male human skull model that displays severe malformation of the left skull half, with cleft jaw and palate. The A29/3 has an original human skull cast to provide accurate representation of fissures, foramina, processes, and sutures, and has 29 teeth that are individually inserted to provide realistic dentition. The model is handmade of plastic for durability. Anatomical models are typically used as educational aids in medical and scientific classroom and office settings.

The model measures 28.0 x 19.5 x 23.0cm/11.0 x 7.7 x 9.1 inches (H x W x D), and weighs 0.8kg (1.76lb.) (H is the vertical distance from the lowest to highest point; W is the horizontal distance from left to right; D is the horizontal distance from front to back.)

3B Scientific manufactures anatomical models, simulators, charts, and other training materials for use in scientific, medical, and patient education. Founded in 1948 and headquartered in Hamburg, Germany, 3B Scientific meets ISO 9001: 2008 standards.
