PURPOSE To report on the clinical outcome of 150 extrasinus zygomatic implants placed lateral to the maxillary sinus and combined with conventional implants in the anterior maxilla for the implant-supported rehabilitation of the edentulous maxilla. MATERIALS AND METHODS All patients included in this study presented with completely or partially edentulous maxillae with any remaining teeth indi...

conclusions this study shows that simultaneous arch osteotomy and coronoidectomy may be an appropriate treatment procedure for zygomatico-coronoid interference. introduction zygomatico-coronoid interference is a rare type of mandibular extracapsular ankylosis. there is a lack of information on the treatment of these cases in the literature. condylectomy and coronoidectomy are not always the bes...

Aim: The zygomatic bone is the key component of the structural facial aesthetics as it constitutes the prominence of the cheek bone. Also, the most frequent clinical findings in zygomatic arch fracture includes limitation of jaw movement and flattening of cheek. So it is necessary to elevate the arch precisely. Therefore, a prospective study was conducted toevaluate adequacy for reduction of zy...

This report details the use of zygomatic oncology osseointegrated implants to support and retain a maxillary obturator in a 13-year-old male patient who underwent a right-sided hemi-maxillectomy (Brown Class 2b) (Brown and Shaw, Lancet Oncol 11:1001-8, 2010) for a myxoid spindle cell carcinoma. At the time of maxillary resection, two zygomatic oncology implants were inserted into the right zygo...

PURPOSE A new approach for zygomatic implant placement was proposed to eliminate the risk of maxillary sinusitis related to the procedure. MATERIALS AND METHODS A prospective study of this new approach was conducted, and consecutive patients treated between June 2007 and December 2008 were included. An extended sinus lift with retained bone window was performed, such that zygomatic implants w...

PURPOSE To evaluate the clinical outcome of maxillary prostheses supported by four immediately loaded zygomatic implants after 1 year of function. MATERIALS AND METHODS Seventeen patients were consecutively included and followed up to 1 year after prosthetic loading. Patients had severely atrophic maxillae (Cawood and Howell classification C-VI and D-V or D-VI) and were rehabilitated using fo...

The zygomatic bone is derived evolutionarily from the orbital series. In most modern mammals the zygomatic bone forms a large part of the face and usually serves as a bridge that connects the facial skeleton to the neurocranium. Our aim is to provide information on the contribution of the zygomatic bone to variation in midfacial protrusion using three samples; humans, domesticated dogs, and mon...

AIM Zygomatic implants have been introduced for the rehabilitation of patients with severe bone defects of the maxilla. The soft tissue aspects of the palatal emergence situation have not been described yet. The aim of this study was to evaluate the incidence and clinical impact of possible periimplant alterations of zygomatic implants. MATERIALS AND METHODS From 1998 to 2001 all patients wit...

BACKGROUND The use of a specially designed implant to be anchored in the zygomatic body has been proposed as an alternative to bone grafting in the prosthetic rehabilitation of the severely resorbed maxilla. However, few studies have evaluated the long-term stability and soft tissue conditions of zygomatic implants. PURPOSE The aim of this retrospective study was to evaluate the clinical perf...

BACKGROUND AND OBJECTIVES The aim of this paper is to investigate epidemiological data (age, gender), sites, etiology and surgical approach of zygomatic fracture. MATERIALS AND METHODS A 9 years retrospective clinical and epidemiologic study evaluated 642 patients treated for zygomatic fracture. There were 569 men and 77 women. The age range was 2 to 86 years with 205 (31.9%) in the 21 to 30 ...
