Interventions for replacing missing teeth: dental implants in zygomaticbone for the rehabilitation of the severely deficient edentulous maxilla. Dental implants are used for replacing missing teeth. Placing dental implants is limited by the presence of adequate bone volume permitting their anchorage. Several bone augmentation procedures have been developed to solve this problem. Zygomatic implants are long screw-shaped implants developed as a partial or complete alternative to bone (...) augmentation procedures for the severely atrophic maxilla. One to three zygomatic implants can be inserted through the posterior alveolar crest passing through the maxillary sinus, or externally to it, to engage the body of the zygomaticbone. A couple of conventional dental implants may also be needed in the frontal region of the maxilla to stabilise the prosthesis. The potential main advantages of zygomatic implants could be that bone grafting may not be needed and a fixed prosthesis could be fitted
Zygomaticbone metastasis from hepatocellular carcinoma and the therapeutic efficacy of apatinib: A case report and literature review. Hepatocellular carcinoma (HCC) metastases to the zygomaticbone are extremely uncommon, and the treatment of target drugs against such case is unknown.A 48-year-old male patient was admitted to our hospital under suspicion of an advanced liver tumor due to an increase in levels of alpha-fetoprotein (AFP) after radiofrequency ablation for independent nodule (...) by symptomatic treatments. As of last follow-up, the patient is unwell with pain in the face, blurred vision in the right eye, dyscrasia, and exhibited difficulty in opening his mouth.HCC metastases to the zygomaticbone are very aggressive with a very low incidence and immunohistochemistry is useful diagnostic indicators. Still now, there is no optimal treatment strategy for these patients. Apatinib may be a promising drug in the treatment of HCC metastases to the zygomaticbone.
Unusual occurrence of orbital hemangiopericytoma in the zygomaticbone of an adolescent: a case report Hemangiopericytoma and solitary fibrous tumor are considered related variants on the same spectrum and both may essentially be the same tumor. They are infrequently encountered in the orbital region while the zygomaticbone is an extremely rare location for these neoplasms to occur.A 14-year-old boy presented with complaint of deformity of left infraorbital area and a firm, regular mass (...) in the region. Orbital CT scan revealed a well-defined round isodense intraosseous lesion in the lowermost portion of the lateral orbital wall (zygomaticbone), expanding the bone and protruding anteriorly and medially. MRI showed the mass to be heterogenous and strongly enhancing with contrast medium. Inferior transconjunctival orbitotomy was performed and the mass was removed. The histopathologic examination and immunohistochemistry staining results (positive for CD34, CD31 and smooth muscle actin
Treatment of cryotherapy and orthotopic transplantation following chondromyxoid fibroma of zygomaticbone: A case report. Chondromyxoid fibrotherma (CMF) is a rare benign cartilage tumor that occurs more frequently in young males at the age of 20 to 30. It occurs more frequently on long bones, but rarely involves craniofacial bones.This study mainly introduced a 30-year-old male with CMF of zygomaticbone. Single tumor excochleation was conducted initially. However, CMF reoccurred (...) , and then the following steps were adopted: firstly, the tumor was extensively excised; secondly, in vitro tumor excochleation was conducted; thirdly, the excised tumor bone was placed in liquid nitrogen for 3 cycles of cryoablation; finally, the orthotopic transplantation was performed to reconstruct the zygomatic appearance, with satisfactory follow-up efficacy obtained.Orthotopic transplantation after tumorectomy and cryopreservation of tumor bone in liquid nitrogen could lead to excellent therapeutic efficacy

Pneumatization of the zygomatic process of temporal bone on computed tomograms Zygomatic air cells (ZAC) are a variant of temporal bone pneumatization that needs no treatment. However, ZAC can have an impact on surgical procedures in the temporo-mandibular joint region. Recent reports suggest that computed tomography will disclose more ZAC than can be diagnosed on panoramic radiography. The aim of this study was to analyze ZAC prevalence on CT in a population that was not pre-selected (...) to the zygomatic process of the temporal bone that has no volume effect on the shape of the process.ZAC is an anatomical variant of the temporal bone that has come into focus of maxillofacial radiology due to its noticeable aspect on panoramic radiograms. The harmless variant can be expected in about one in thirteen individuals undergoing facial radiology. Panoramic radiograms appear to be sufficient to present ZAC of relevant size. However, in preparation for surgical procedures affecting the articular
A Hemangioma of the ZygomaticBone: Management Ensuring Good Reconstructive and Aesthetic Results Hemangiomas are benign tumors representing only 0.7 to 1% of all bone tumors; those that arise in the zygomatic region are rarely described in the literature. Here, we describe the case of a 55-year-old woman with a mass in the right orbitozygomatic region. She was diagnosed on the basis of preoperative clinical manifestations, data from an earlier histopathological examination, and computed (...) tomography (CT). The CT scan revealed a lesion in the right zygomatic region at the level of the cancellous component. This caused thinning and remodeling of the deformed cortex both medially and laterally. Surgery was performed. We describe the clinical characteristics of our case with an emphasis on surgical management of the lesion using a titanium grid prepared by reference to a stereolithographic model.

of the central incisor, simulating the occlusal load during mastication, in a total of 150 N.The extramaxillary technique presented considerable variation in increased tension on the prosthesis screws and bone tissue. In the exteriorized technique, the highest tension values occurred in the region of the ridge, and the lowest, on the zygomatic process; the absence of cantilever reduced the stress on bone tissue in almost all regions.The exteriorized technique was shown to be more favorable (...) to the distribution of stresses on the micro-unit screws and bone tissue, with the model with zygomatic implant placed in the region of the first molar and inclined anterior implant presenting the best results.
Oral Rehabilitation of Oral Cancer Patients Using Zygomatic Implant-Supported Maxillary Prostheses with Magnetic Attachment: Three Case Reports Maxillectomy for malignant tumor often results in a maxillary defect and serious oral dysfunction. A prosthesis is usually provided for postoperative oral rehabilitation of such patients with maxillary defects. However, the further the resected region extends, the less stable the prosthesis becomes, due to insufficient bone and tooth support. Therefore (...) , in many cases, conventional resection dentures may not be adequate to restore the oral function. Effective utilization of dental and zygomatic implants may help to restore oral function in patients with severe maxillary defects. This clinical report describes the management of three patients with severe maxillary defects following cancer ablative surgery who were rehabilitated using maxillary prostheses with magnetic attachments supported by dental and zygomatic implants.

Anatomical Thin Titanium Mesh Plate Structural Optimization for Zygomatic-Maxillary Complex Fracture under Fatigue Testing This study performs a structural optimization of anatomical thin titanium mesh (ATTM) plate and optimal designed ATTM plate fabricated using additive manufacturing (AM) to verify its stabilization under fatigue testing. Finite element (FE) analysis was used to simulate the structural bending resistance of a regular ATTM plate. The Taguchi method was employed to identify (...) height to be 10 mm. The designed plate thickness factor primarily dominated the bending resistance up to 78% importance. The averaged micromotion (displacement) and strain of the maxillary bone showed that ZMC fracture fixation using the miniplate was significantly higher than those using the AM optimal designed ATTM plate. This study concluded that the optimal designed ATTM plate with enough strength to resist the bending effect can be obtained by combining FE and Taguchi analyses. The optimal
Developmental constraint through negative pleiotropy in the zygomatic arch Previous analysis suggested that the relative contribution of individual bones to regional skull lengths differ between inbred mouse strains. If the negative correlation of adjacent bone lengths is associated with genetic variation in a heterogeneous population, it would be an example of negative pleiotropy, which occurs when a genetic factor leads to opposite effects in two phenotypes. Confirming negative pleiotropy (...) and determining its basis may reveal important information about the maintenance of overall skull integration and developmental constraint on skull morphology.We identified negative correlations between the lengths of the frontal and parietal bones in the midline cranial vault as well as the zygomaticbone and zygomatic process of the maxilla, which contribute to the zygomatic arch. Through gene association mapping of a large heterogeneous population of Diversity Outbred (DO) mice, we identified
Single piece fronto-temporo-orbito-zygomatic craniotomy: a personal experience and review of surgical technique. Fronto-Temporo-Orbito-Zygomatic (FTOZ) craniotomy has progressed from its humble beginnings. Numerous variations including one piece, two piece and even three piece FTOZ craniotomies have been described. The ideal technique still remains elusive and its use remains restricted to a few specialised centres even when benefits far outweigh the surgical difficulties.To analyse 11 cases (...) of single piece of bone. It provides a wide, multidirectional access to skull base. Lesions become shallow and their access easier. Benefits far outweigh the difficulties if any, and its use should be encouraged even at centres outside of the specialised units.
Developmental and Evolutionary Significance of the ZygomaticBone The zygomaticbone is derived evolutionarily from the orbital series. In most modern mammals the zygomaticbone 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 zygomaticbone to variation in midfacial protrusion using three samples; humans, domesticated dogs, and monkeys. In each case, variation (...) in midface protrusion is a heritable trait produced by one of three classes of transmission: localized dysmorphology associated with single gene dysfunction, selective breeding, or long-term evolution from a common ancestor. We hypothesize that the shape of the zygomaticbone reflects its role in stabilizing the connection between facial skeleton and neurocranium and consequently, changes in facial protrusion are more strongly reflected by the maxilla and premaxilla. Our geometric morphometric analyses
