For correction of severe arch constriction and overjets
The Biobloc (Stage 1, 2 and 3) appliances are useful alternative arch development methods in MRC's treatment systems. The appliances are used sparingly as they cannot be combined with MRC's appliances to improve function and, when used, it is mainly the Biobloc Stage 1 (BB1) or, very rarely, the Stage 3 (BB3). The Biobloc Stage 1 is useful for severe arch restrictions (especially transverse) when the BWS cannot be used. It is reserved mainly for use in the primary or early mixed dentition, as well as approximating the central incisors. The Biobloc is proficient in quick expansion of the arches in all three dimensions but is very technique sensitive and tends to worsen patients' function. The Biobloc Stage 3 is used for patients with a severe overjet who cannot retain their Myobrace® appliance. This page will focus on the Biobloc Stage 1 appliance, since the others are not commonly used in Myobrace® treatment.

The Biobloc requires further training in order to become competent in its use. For more information on the Biobloc, please complete our advanced online courses.
Incorrect usage of the appliance can result in adverse side effects.
