introduction: maxillary osteomyelitis is a rare phenomenon. if it occurs, evaluation for underlying disease especially osteopetrosis must be considered. osteomyelitis occurs as a complication in 10% of the cases of osteopetrosis. case report: this is a case report of maxillary osteomyelitis presented in a 15-year old boy with osteopetrosis.  in this case, the disease represented mainly with fac...

hemangiomas of the sinonasal tract are rare, and because these lesions lack the typical signs or symptoms, they can be confused with other malignant conditions. we report a case of cavernous hemangioma of the maxillary sinus in a 68-year-old man that was completely resected by endoscopic sinus surgery. although computed tomography (ct) and magnetic resonance imaging (mri) showed several enhanci...

Introduction: Maxillary sinuses are among the largest paranasal sinuses with various shapes and volumes. The dimensions and volumes of maxillary sinuses play an important role in the surgical treatment plan. The higher levels of pneumatization of alveolar bone lead to the increase of odontogenic sinusitis which cause problems in dental implantation. Therefore, this study aimed to evaluate...

BACKGROUND A facial bone (<2 mm) overlying maxillary anterior teeth may be prone to resorptive processes after extraction and immediate implant placement. A thin bone contributes to risk of bone fenestration, dehiscence, and soft-tissue recession. This study measures the distance between the cemento-enamel junction (CEJ) and alveolar bone crest and the thickness of facial alveolar bone at point...

AIM The study aimed to investigate the proximity of maxillary posterior teeth roots to maxillary sinus and measure the distance of maxillary posterior teeth roots and the sinus floor as well as the thickness of bone between the roots and alveolar cortical bone using Denta scan®. MATERIALS AND METHODS The study samples include Denta scan® images of fifty patients with normally erupted bilatera...

conclusions alendronate may be considered a therapeutic option for improving the bone formation process and reducing resorption in different bone grafting procedures. further detailed studies should focus on dosage and time-dependent effects of alendronate on bone remodeling. results at 6 weeks, the bone area was significantly larger in the xenograft-alendronate group (33.0% ± 5.0%) than in the...

OBJECTIVE The purpose of this study was to quantitatively evaluate the cortical bone densities of the maxillary and mandibular alveolar processes in adults with different vertical facial types using cone-beam computed tomography (CBCT) images. METHODS CBCT images (n = 142) of adult patients (20-45 years) were classified into hypodivergent, normodivergent, and hyperdivergent groups on the basi...

Antral septa of the maxillary sinus occurs in approximately one third of patients undergoing posterior maxillary bone augmentation and is considered a relative contraindication for lateral maxillary window ("hinge osteotomy"). We present the results of 26 consecutive cases of patients with septated maxillary sinus who underwent minimally invasive antral membrane balloon elevation (MIAMBE) follo...
