Accuracy of mid-face advancement using patient specific osteotomy/plates locating surgical guides with pre-bent plates vs conventional interocclusal wafer in quadrangular Le Forte II osteotomy: A randomized controlled trial

The aim of this study was to assess the accuracy of quadrangular Le Fort II osteotomy and mid-face advancement utilizing digitally fabricated surgical guides with pre-bent plates compared to the conventional interocclusal wafers. Twenty patients with mid-face deficiency were allocated randomly in two groups: Patient specific osteotomy/plates locating surgical guides and pre-bent titanium mini-plates were utilized in the study group while conventional interocclusal wafers with intraoperatively adapted titanium mini-plates were utilized in the control group.
