Fabricating an immediate complete denture can be very challenging in some clinical situations. This report describes a digital workflow to fabricate printed maxillary for patient with severely compromised maxilla. Digital data obtained by using intraoral scanner was utilized reconstruct the three-dimensional (3D) image of jaws at desirable vertical dimension occlusion. After performing virtual ...

IMPORTANCE Osteosarcoma of the jaws is rare and clinically distinct from osteosarcoma of the long bones of the body with different treatment and outcomes. The literature on these tumors is limited to case reports and small case series mostly from single institutions. We used data from the population-based national Surveillance, Epidemiology and End Results (SEER) cancer registry to determine th...

The horn sharks (Heterodontidae: Chondrichthyes) represent one of four independent evolutions of durophagy in the cartilaginous fishes. We used high-resolution computed tomography (CT scanning) to visualize and quantify the mineralized tissue of an ontogenetic series of horn sharks. CT scanning of neonatal through adult California horn sharks (Heterodontus francisci) confirmed that this techniq...

BACKGROUND For the treatment of the bisphosphonates and other drugs related osteonecrosis of the jaws, currently medication-related osteonecrosis of the jaws (MRONJ), have been established different conservative therapeutic approaches, avoiding surgery except in cases of extreme need. Given the controversy and lack of current consensus regarding MRONJ therapy in patients, new techniques have be...

Introduction: Giant cell lesions of the bone comprise a group of jaw bone pathologies. Different pathogeneses such as reactive, vascular or neoplastic have been proposed for these lesions. In addition, differentiating between aggressive and nonaggressive central giant cell granuloma (CGCG) of the jaws based on histopathologic features is still impossible and due to different treatment protocols...

BACKGROUND AND AIM: The present study was performed in order to assess the effect of gingival thickness on amount of gingival augmentation with and without preserving periosteum.METHODS: The study was conducted on 8 ecotype dogs aged 1-5 years. At the beginning, clinical probing depth and keratinized and attached gingiva width were measured. Totally, 64 sites were operated in this study. Perios...

Background The surgical treatment of patients affected by BRONJ (Bisphosphonate-related osteonecrosis of the jaw) represents one of the most debated issues in the international literature becouse the data reported to date are preliminary results of long-term studies. In accordance with the guidelines proposed in 2007 by the American Association of Oral and Maxillofacial Surgeons position paper ...

Although a strong correlation between jaw mechanics and prey selection has been demonstrated in bony fishes (Osteichthyes), how jaw mechanics influence feeding performance in cartilaginous fishes (Chondrichthyes) remains unknown. Hence, tooth shape has been regarded as a primary predictor of feeding behavior in sharks. Here we apply Finite Element Analysis (FEA) to examine form and function in ...

background and objectives: there are a few studies on histopathologic type of oral lesions especially from iran. the aim of this study was to survey the oral lesions in babol, northern iran. methods: the histopathology records were retrospectively reviewed for all lesions of oral cavity and jaws, during the years 1990 to 2009. the data were collected from the archive of pathology and analyzed ...
