Split-mouth comparison of physics forceps and extraction forceps in orthodontic extraction of upper premolars

Br J Oral Maxillofac Surg. 2014 Dec;52(10):e137-40. doi: 10.1016/j.bjoms.2014.06.013. Epub 2014 Jul 8.


We compared outcome variables (operative complications, inflammatory complications, and operating time) in patients being treated by orthodontic extraction of upper premolars with the Physics forceps or the universal extraction forceps. We organised a single blind, split-mouth clinical trial to compare the outcomes of the 2 groups (n=54 premolars). The Physics forceps group had lower mean (SD) visual analogue scores (VAS) for pain (0.59 (0.57)) on the first postoperative day than the other group (1.04 (0.85)) (p=0.03). There were no other significant differences between the 2 groups in any other variable studied.

Keywords: Atraumatic extraction; Inflammatory complications; Operative complications; Physics forceps; Upper premolar extraction; extraction forceps.
