Comparison reproducibility between the facebow and a new technique based on a spirit level device.

: This study aimed to introduce a spirit level device for mounting maxillary casts to compare the reproducibility between the facebow and this new technique.: The maxillary casts of 10 participants were mounted in three different situations: 1) with the facebow; 2) with the spirit level device, the participant in seated position; and 3) with the spirit level device with participant in standing position. Each procedure was performed by three different evaluators.

A Cephalometric Analysis for Evaluation of Changes in Soft Tissues in the Regions of the Upper and Lower Lips and Chin due to Orthognathic Maxillary Advancement Surgery.

Introduction There is currently no consensus regarding the best method for predicting the changes in soft tissues due to the modification of hard tissues in orthognathic surgery. Objective To measure the changes in soft tissues of the upper lip, lower lip, and chin regions due to the modifications of hard tissues caused by orthognathic maxillary advancement surgery using a cephalometric methodology. Methods The study was conducted on 35 patients with dentoskeletal and facial deformities submitted to orthognathic maxillary advancement surgery.
