Restricted Activities under the Health Practitioners Competence Assurance (HPCA) Act
 
Section 9 of the HPCA Act allows for specified activities to be restricted to registered health practitioners, in order to protect members of the public from serious or permanent harm.
 
As of 1 August 2005 the following oral health procedures have been deemed to be restricted activities:
  • Surgical or operative procedures below the gingival margin or the surface of the skin, mucous membranes or teeth
  • Clinical procedures involved in the insertion and maintenance of fixed and removable orthodontic or oral and maxillofacial prosthetic appliances
It is illegal for anyone other than a health practitioner registered under the HPCA Act to perform these or any other restricted activity, regardless of whether they are working under supervision. The only exception to this is if the activity is performed in an emergency situation.
 
The Council's Policy Statement on Restricted Procedures under the HPCA Act 2003 defines the restricted procedures.
