Background: Pneumatized air cells present in the zygomatic process of the temporal bone are termed Zygomatic Air Cell Defects (ZACDs). They are merely the extensions of the mastoid air cells anteriorly into the zygomatic process of the temporal bone which are important for surgical perspective. Panoramic radiography is useful to display these zygomatic air cell defects. Aim: This study was unde...

A 10-year-old castrated Shih-Tzu male dog was referred for examination of acute right exophthalmos, protrusion of the third eyelid and soft tissue swelling ventral to the globe. Ultrasonography revealed echogenic fluid around the right globe. Computed tomography (CT) showed an enlarged right zygomatic salivary gland compared with the left zygomatic gland and an amorphous cystic mass ventral to ...

Objective To obtain anatomical data of maxillary-zygomatic complex based on simulating the zygomatic implantation using cadaver heads and three-dimensional computerized tomography (3D-CT). Methods Simulating zygomatic implantation was performed using seven cadaver heads and 3D-CT images from forty-eight adults. After measuring the maxillary-zygomatic complex, we analyzed the position between ...

PURPOSE This clinical study using a specific technique was carried out to determine the clinical effectiveness of zygomatic implants under an immediate loading protocol. MATERIALS AND METHODS All patients treated between May 2000 and October 2006 who received zygomatic implants were included in this retrospective analysis. All patients were treated using the same surgical and restorative prot...

This paper aimed to analyze stress distribution in human zygomatic pillar during masseter muscle contraction using three-dimensional finite element analysis. A three-dimensional model and hemi facial skull were produced based on CT-scan data. An adult male skull with structural anatomy integrity was used as model. Muscles forces were applied at origin of elevator muscles and supports was applie...

conclusions this approach may be an appropriate approach to the zygomatic arch in the zmc fractures and eliminates the use of the coronal flap. introduction zygomatic arch fractures are common injuries in the maxillofacial injuries. sometimes it is necessary to fix the unstable fragments of the zygomatic arch. case presentation we introduce a combination of transconjunctival and lateral canthot...

PURPOSE Specifically with zygomatic implants, the bone-to-implant contact (BIC) at the zygomatic bone correlates with the survival of the implant because there is little anchorage at the alveolus. The purpose of this retrospective study was to view and measure the BIC of zygomatic implants in the zygomatic bone. MATERIALS AND METHODS The patients in this study received zygomatic implants at a...

AIM This study aimed to evaluate the length of the holes drilled for the placement of zygomatic implants using two surgical techniques: the original Brånemark and the Exteriorized (extrasinus) protocols. The most frequent implant length used and position where the implants emerged in the zygomatic bone were recorded. MATERIALS AND METHODS Both surgical techniques for inserting zygomatic impla...

PURPOSE This prospective study was designed to assess the long-term outcome of immediately loaded zygomatic implants placed in atrophic maxillae. MATERIALS AND METHODS Forty-two consecutively treated patients received 81 zygomatic implants and 140 conventional implants for oral rehabilitation and were followed for 5 years. Complete arch rehabilitation was accomplished in 37 patients and parti...

BACKGROUND This study aimed to evaluate patients undergoing placement of zygomatic implants by Stella and Warner's technique, considering the survival rate of conventional and zygomatic implants, and assess the health of the maxillary sinuses and the level of patient satisfaction. METHODS In this retrospective cohort study, 28 patients had received a combination of conventional and zygomatic ...
