introduction plasma cell dyscrasias are characterized by a monoclonal neoplastic proliferation of plasma cells. solitary bone plasmacytoma (sbp) is a local form of the disease with the vertebrae and long bones being the most frequently encountered sites. its prevalence in the maxillofacial area is extremely rare. case presentation a 70-year-old caucasian male patient was referred for the extrac...

PURPOSE In this study we tried to analyze the stress distribution in a symphyseal fractured human mandible reduced by 2 different methods--reduction with 1 miniplate or with 2 miniplates--by using finite element (FE) analysis, and then compared the results with an intact mandible. MATERIALS AND METHODS Three-dimensional FE models of an intact mandible and symphyseal fractured mandibles reduce...

The aim of the present study was analyze, by histological and morphometrical studies, mandibular glands of Melipona bicolor queens collected from monogynic and polygynic colonies and compare their level of development. The results showed that the glands ofphysogastric queens from monogynic colony present a higher level of activity in relation to the queens of polygynic colonies; this is explain...

myofibroma is an uncommon benign mesenchymal neoplasm. solitary myofibroma is common in soft tissues of head and neck, but rare in the jaw bones. only a few sporadic cases of solitary myofibroma of mandible have been described. the aim of the present study was to present a clinical case of a patient with a myofibroma in mandible bone and its management. differentiating this lesion from other be...

Residual ridge resorption is most commonly seen in the mandible and its prosthodontic management is always a challenge to a general dentist. One of the methods of improving the retention, stability and support of such severly resorbed atrophic mandible is through proper impression technique. This article describes a modied putty wash technique for recording impression of atrophic mandible with...

ameloblastomas are tumors of odontogenic epithelial origin. the term unicystic ameloblastoma is used to describe cystic lesions with clinico-radiographic features resembling an odontogenic cyst, but histologically showing the presence of ameloblastomatous epithelium lining part of the cyst cavity. a large majority of lesions are found in the mandible, and usually cause a painless swelling of th...

intraosseous migration is an unusual developmental dental anomaly, which demonstrates horizontal movement of unerupted teeth only affecting the permanent dentition of the lower jaw. mandibular second premolar is the most common impacted tooth after the third molars and maxillary canines. distal migration of the second premolar is rare and early loss of the permanent first molar is one of the mo...

abstract objectives: radiomorphometric indices measured on simple radiographic images can be used for qualitative and quantitative assessment of bone. panoramic radiographic imaging can therefore assist dentists in early detection of osteoporosis in patients. considering the effect of ethnic and environmental factors on development of osteoporosis and absence of normal values of radiomorphometr...

BACKGROUND This study aimed to establish surgical guiding techniques for completing mandible lesion resection and reconstruction of the mandible defect area with fibula sections in one surgery by applying additive manufacturing technology, which can reduce the surgical duration and enhance the surgical accuracy and success rate. METHODS A computer assisted mandible reconstruction planning (CA...
