Soft tissue fillers are comprised of a range of materials with differing physiochemical and rheologic (ie, flow) properties.

These properties can inform treatment selection for specific anatomic areas, planes of injection, and clinical applications.

The aim of this study was to characterize the rheologic properties of polymethylmethacrylate (PMMA)-collagen gel for comparison with other available fillers.

Commercially available PMMA-collagen gel, hyaluronic acid (HA), and calcium hydroxylapatite (CaHA) fillers were obtained from their respective manufacturers.

Measures of complex viscosity (η*) and elastic modulus (G′) for each filler were collected at 0.7 Hz in triplicate according to standard procedures on a rotational rheometer fitted with a 40-mm steel plate at 25°C on a Peltier plate (500-μm gap).
