Congenital granular cell lesion (CGCL) is a rare non-neoplastic lesion found in newborns also known as Neumann's tumor. This benign lesion occurs predominantly in females mostly as a single mass. The histogenesis and natural history of the lesion remains obscure. It arises from the mucosa of the gingiva, either from the maxillary or mandibular alveolar ridge. The lesion is more common in the ma...

Successful osseointegration of the dental implants requires sufficient bone volume surrounding implant site. The mandibular ramus is considered reliable donor site for reconstructing alveolar ridge defects prior to dental implant placement. The aim of this study was to present the clinical efficiency of using ultrasound surgery for harvesting mandibular ramus bone graft. 20 patients (10 male, 1...

The consequences of exodontia include alveolar bone resorption and ultimately atrophy to basal bone of the edentulous site/ridges. Ridge resorption proceeds quickly after tooth extraction and significantly reduces the possibility of placing implants without grafting procedures. The aims of this article are to describe the rationale behind alveolar ridge augmentation procedures aimed at preservi...

PURPOSE To investigate the clinical and histologic features of frictional keratoses located exclusively on the facial attached gingiva and establish whether these belong to the category of leukoplakia. MATERIALS AND METHODS Over a period of 15 years, 159 patients presenting with oral keratotic plaques, located exclusively on the facial attached gingival mucosa, excluding the edentulous alveol...

Young’s Branch (YB), located on a portion of the Wayne National Forest in Lawrence County, is located on bedrocks belonging to the Allegheny group. By contrast, Bluegrass Ridge (BR), the other study area in Lawrence County, is underlain by sedimentary strata of the Connemaugh group. The bedrock complex includes a combination of sandstones, sandy shales (or siltstones), and clay shales (Denton e...

The aim of this study was to assess the presence, location and, multiplanar distance of the canalis sinuosus (CS) between the incisive foramen and the anterior maxillary alveolar ridge using cone beam computed tomography (CBCT). Therefore, 500 CBCT maxillary images obtained from male and female patients aged 20 to 80 years were selected to assist in the dental treatment. Low-quality tomographic...

OBJECTIVES To assess the association between muscle invasion by oral squamous cell carcinoma of the posterior mandibular alveolar ridge and cervical lymph node metastasis on the basis of preoperative magnetic resonance imaging (MRI). MATERIALS AND METHODS Twenty-six patients with oral squamous cell carcinoma of the posterior mandibular alveolar ridge were evaluated by MRI. The associations be...

Alveolar bone splitting and immediate implant placement have been proposed for patients with severe atrophy of the maxilla in the horizontal dimension. A new modification of the classical alveolar bone splitting for the treatment of the narrow ridge in the maxilla is provided. Thirty-three dental implants in eight consecutive patients were evaluated retrospectively following the described modif...

In this study, we investigated cases of mal fracture occurring during the split-crest procedure. In all subjects (six patients), the free cortical bone segment caused by the mal fracture was carefully maintained in the lateral position without fixation using a titanium plate or screw. On pre- and postoperative multiplanar reconstruction CT, the average total alveolar increase was 5.0 mm in the ...
