Abstract

Objective: To measure and compare the amount, rate and anchor loss after the en masse retraction of all anteriors with titanium mini-implant anchorage and conventional molar anchorage.

Methods: This comparative clinical study sample comprised 12 patients (10 females, 2 males; mean age between 16 and 22 years). The implants were placed in the maxillary and mandibular arches. Preretraction and post retraction lateral cephalograms were taken for measuring the amount, rate and anchor loss after the retraction.

Results: Mean en masse retraction amounts, the rate of movement per month, and horizontal and vertical anchor loss at the maxillary implant site were 4.79 mm, 0.58 mm, 0 mm, and 0 mm, respectively. In the mandible, on implant sides were 4.66 mm, 0.56 mm, 0 mm, and 0 mm. Mean en masse retraction amounts, the rate of movement per month, and horizontal and vertical anchor loss at the maxillary conventional molar anchor side were 4.08 mm, 0.49 mm, 2.91 mm, and 1.66 mm. In the mandible, on conventional anchor sides were 3.54 mm, 0.48 mm, 3.12 mm, and 1.95 mm.

Conclusion: En masse retraction had a faster rate of space closure with mini-implants as anchor units than the conventional molar anchorage preparation.
