Introduction: In Orthodontics over-eruption of maxillary molar is a common clinical finding which occurs due to the long-term absence of occlusal contact with its opposing antagonist. Intrusion of single over-erupted molar is a challenge for the orthodontists. Among the various procedures described in literature, mini-screws and TADs are popular. Also modified TPA engaging elastics in distal hooks has been described. However it needs patient compliance.
Methodology: In this case-report, the authors have used a simple modification of TPA. The M-TPA was made with 0.8 mm stainless steel wire with asymmetrical, unequal arms. The shorter arm was engaged to the palatal sheath of the molar to be intruded, so that the appliance lies at 4 mm from palate.
Result & Conclusion: The intrusion was achieved within 3 months. The method is easy, simple, non-invasive with reduced chair-side time and cost-effective.
