There are a range of different methodologies available, all with their own strengths and drawbacks. It is vital for orthodontists to understand indications and clinical scenarios where IPR can prove a useful tool, and situations in which it is not advisable. Understanding the appropriate uses and techniques of IPR will allow orthodontists to integrate it into their own practice and enhance clinical outcomes.
