Interproximal reduction (IPR) of enamel involves the removal of outer enamel (0.3–0.5 mm) on the interproximal surfaces of teeth. IPR is one of the techniques that may be used during orthodontic treatment to provide extra intra-arch space in patients with mild to moderate crowding and when extraction therapy is undesirable.
Advantages of IPR -
-Decreased treatment time
- Prevention of interdental gingival retraction.
- Help to acquire additional space to create ideal tooth alignment.
Interproximal enamel stripping has become an effective orthodontic treatment approach to regain space, improve tooth and gum aesthetics as well as maintain post-treatment stability. Nevertheless, orthodontists should choose appropriate indications by balancing between its benefits and risks.
