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.

A Novel Design of Computer-Assisted 3D-Printed TMJ Arthrocentesis Guide (Technical Note).

Attempts of needle relocation and extension of the operation time are the most common cause of postoperative edema and swelling after temporomandibular joint arthrocentesis. To facilitate the placement of needles and decrease patient discomfort, a template-based technique that includes design of patient-specific guide was performed to direct access to the temporomandibular joint space for arthrocentesis.

Segmentation of the 3D printed mirror image auricular model to ease sculpture of the costal cartilages in total auricular aesthetic reconstruction.

Background: Recently, three-dimensional (3D) models have been used more frequently than the traditional two-dimensional (2D) models as an intraoperative guide to ease sculpture of costal cartilages in total auricular aesthetic reconstruction in cases of microtia. Usually, 3D imaging techniques are used to create compact ear models, however, there is insufficient clinical knowledge of using them to create segmented 3D auricular models for cartilage framework reconstruction. IN THIS STUDY: assessment of the advantages of segmentation of 3D models over the traditional compact 3D models in total auricular aesthetic reconstruction has been discussed.

The evaluation of the effect of performing guided lid surgery with enucleation of a cystic lesion; a case report.

Introduction And Importance: Dentigerous cysts are benign odontogenic cysts of developmental origin. Enucleation and marsupialization are still considered the blueprint of cystic lesion treatment.

Case Presentation: A 23-year-old male patient presented complaining of a minimal swelling in his upper jaw with slight tenderness in his upper anterior teeth.

The correction of asymmetry using computer planned distraction osteogenesis versus conventional planned extra-oral distraction osteogenesis: A randomized control clinical trial.

The aim of the current study was to evaluate the effect of the use of computer-guided surgical templates in association with mandibular distraction osteogenesis to correct mandibular asymmetry. In the study group a simulation process was conducted to restore the exact position of the chin skeletally by planning the osteotomy orientation, distractor vector, pin positions, and distraction distance calculation. The Control group was treated with conventional distraction in which an oblique osteotomy was done, and distraction was performed until the midline coincided.

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.

Novel Technique and Step-by-Step Construction of a Computer-Guided Stent for Mandibular Distraction Osteogenesis.

Introduction: Distraction osteogenesis is an integral part in management of mandibular defects associated with hemifacial microsomia and post-ankylotic mandibular defects. The most difficult part in distraction osteogenesis is the prediction of distraction vector and risk of injury to vital structures as inferior alveolar. The present study aimed to present 3-dimensionally constructed computer-guided splints in distraction osteogenesis to get an ideal vector and minimal risk of vital structures injury.
