A modified protocol merging two published techniques for computer guided zygomatic implants surgery: a technical note.

Objectives: Zygomatic implant surgery can be difficult due to the limited intraoperative visibility of the surgical field and the complex anatomy of the zygomatic bone, which could lead to serious complications. This study aims to assess the accuracy of zygomatic implants placement using computer-guided surgical templates.

Materials And Methods: A total of 13 zygomatic implants were placed in four participants.

Alveolar bone changes around maxillary incisors after intrusion and retraction with controlled tipping versus bodily movement : A retrospective cone-beam computed tomography study.

Objective: To compare the effect of maxillary incisor intrusion and retraction with controlled tipping (CT) versus bodily movement (BM) in extraction cases on alveolar bone height and thickness, using cone-beam computed tomography (CBCT). Correlations between changes in alveolar dimensions and crown or root retraction, incisor inclination, and intrusion were also investigated.

Materials And Methods: In all, 144 incisors of 36 women were retrospectively evaluated.

Using the Dermal Fat Graft as a Barrier Membrane in Unilateral Alveolar Cleft Grafting: A Randomized Clinical Trial.

Introduction: Alveolar cleft grafting is a surgical procedure that usually suffers from inferior results.

Methodology: The patients were divided into 2 groups; study and control. In the study group, the grafted site was covered with a dermal fat graft.

A rare complication of hemolacria after Le fort I osteotomy: a case presentation.

Background: Nasolacrimal duct obstruction (NDO) is a common pathology preventing the proper drainage of the tears, and its main symptom is epiphora. Secondary acquired nasolacrimal duct obstruction (SANDO) can be due to a variety of causes including infection, trauma, or neoplasms. It has been reported to occur with different forms of maxillofacial trauma, especially Le Fort II, Le Fort III, naso-orbital-ethmoidal, and orbital floor fractures.

The Use of Computer-Guided Half Propeller Genioplasty for the Correction of Mandibular Asymmetry (A Mandibular Orthognathic Surgery Without a Condylar Intervention Technical Strategy).

Introduction: Mandibular asymmetry is a facial deformity that results from multiple causes; among these are growth deficiency like hemifacial microsomia and growth excess as in condylar hyperplasia. The facial asymmetry caused by condylar hyperplasia has been treated over the years with different surgical and nonsur-gical modalities dependent on the age of the patient and the severity of the condition. The authors in this article introduce a modified version of the propeller genioplasty technique.

A Systematic Review to Uncover a Universal Protocol for Accuracy Assessment of 3-Dimensional Virtually Planned Orthognathic Surgery.

Purpose: The aim of this study was to systematically review methods used for assessing the accuracy of 3-dimensional virtually planned orthognathic surgery in an attempt to reach an objective assessment protocol that could be universally used.

Materials And Methods: A systematic review of the currently available literature, published until September 12, 2016, was conducted using PubMed as the primary search engine. We performed secondary searches using the Cochrane Database, clinical trial registries, Google Scholar, and Embase, as well as a bibliography search.
