The Effects of Unilateral Alloplastic Temporomandibular Joint Replacement on the Opposite-Side Natural Joint: A Finite-Element Analysis.

Purpose: The purpose of this study was to evaluate the stress distribution on the temporomandibular joint (TMJ) prosthesis and contralateral natural TMJ with finite-element analysis.

Materials And Methods: A TMJ implant was used to create a 3-dimensional model with a computer. This model was integrated with a mandible model created with a computer by use of computed tomography images, similar to a real TMJ replacement procedure.

Efficacy of Ankaferd Blood Stopper on bone healing in diabetic rats: a stereological and histopathological study.

We evaluated the effects of Ankaferd Blood Stopper (ABS) and routine antibiotic prophylaxis (AP) on early healing of bone defects in diabetic rats. We used 48 rats in the study. Diabetes was induced in 24 rats using streptozotocin; the remaining 24 healthy untreated rats served as controls.

Graft necrosis occurred after iliac crest reconstruction after mandibular segmental resection of ameloblastoma.

Ameloblastoma is an uncommon benign odontogenic neoplasm of the maxillofacial region constituting less than 1% of tumors of the oral cavity. Ameloblastomas have been categorized broadly into 3 biologic variants: cystic (unicystic), solid, and peripheral. Unicystic ameloblastoma is a rare and less aggressive variant of ameloblastoma.

Two-year follow-up of early- and conventionally-placed two-stage implants supporting fixed prostheses.

Purpose: The objective of this study was to compare the biologic and prosthetic outcomes of early- and conventionally-placed implants supporting fixed prostheses.

Materials And Methods: Using inclusion/exclusion criteria, early- and conventionally-placed implant patient groups, rehabilitated with Branemark System implants supporting fixed prostheses for 2 years, were selected from the patient archives. Kaplan-Meier survival estimates, time-dependent marginal bone loss, Plaque Index, peri-implant infection, Bleeding Index scores, and prosthetic complications data of the groups were compared.

Intraosseous carcinoma arising from an odontogenic cyst: a case report.

Carcinomas from an odontogenic cyst are not common, yet when they occur, squamous cell carcinomas are the most often seen. Among these cysts, the malignancy of keratocysts or dentigerous cysts are most likely. In contrast, a malignant transformation of a radicular cyst to an intraosseous carcinoma is extremely rare.

Descending necrotizing mediastinitis associated with an infected dentigerous cyst.

Descending necrotizing mediastinitis (DNM) is a rare condition in which an infection from the head and neck propagates into the mediastinum. The most common cause of DNM is odontogenic infection. DNM is spread by the fascial planes from the neck into the mediastinum and requires an aggressive surgical drainage through cervical and thoracic approaches.

Delayed Frey syndrome after closed treatment of condylar fracture.

Frey syndrome is also known as auriculotemporal syndrome and gustatory sweating. It is characterized by the occurrence of hyperesthesia, flushing, and warmth or sweating over the distribution of the auriculotemporal nerve and/or greater auricular nerve while eating foods that produce a strong salivary stimulus. It is commonly seen as a complication of parotidectomy and open surgery of temporomandibular joint.

Comparison of the planimetry and point-counting methods for the assessment of the size of the mandible cysts on orthopantomograms.

Objective: The purpose of this study is to compare the computer-assisted planimetry and point-counting methods in evaluating the sizes of the mandibular cysts with respect to their agreement and the time required to analyze.

Study Design: The surface areas of 46 mandibular cyst lesions on orthopantomograms were estimated using the point-counting and computer-assisted planimetry methods. Three observers evaluated the outlined areas twice, using the point-counting (PC) and computer-assisted planimetry (CAP) methods with an interval of two weeks.

Screw fixation is superior to N-butyl-2-cyanoacrylate in onlay grafting procedure: a histomorphologic study.

The aim of this study is the histopathological evaluation of the efficiency of N-2-butyl cyanoacrylate in the fixation of bone block grafts on mandible. Autogenous monocortical block grafts taken from tibial bone were fixed to the outer surface of the angle of the mandible with N-2-butyl cyanoacrylate on the right side and mini screws on the left side. Postoperatively in the first and third months, six rabbits were killed and tissue samples were obtained from the grafted area.

Use of artificial neural network in differentiation of subgroups of temporomandibular internal derangements: a preliminary study.

Purpose: Artificial neural networks (ANNs) have been developed in the past few decades for many different applications in medical science and in biomedical research. The use of neural networks in oral and maxillofacial surgery is limited. The aim of this study was to determine the use of ANNs for the prediction of 2 subgroups of temporomandibular joint (TMJ) internal derangements (IDs) and normal joints using characteristic clinical signs and symptoms of the diseases.

Diffuse large B-cell lymphoma with oral manifestations.

Non-Hodgkin lymphomas (NHLs) are a heterogenic group of lymphoproliferative diseases with their different behavior pattern and response to treatments. As a Hodgkin disease, NHL occurs from lymphoid tissues and can spread to other organs. Prognosis depends on histologic type, grade, and treatment.

Horizontal alveolar distraction of the mandibular canine regions for implant placement.

Horizontal alveolar augmentation by distraction osteogenesis is an alternative method for reconstructing atrophic alveolar bone. A 65-year-old woman with atrophy of the alveolar rim in the anterior lower jaw, which had inadequate width for implant placement, was presented. Under general anesthesia, vertical and horizontal osteotomies of the buccolabial cortical bone were performed in the canine regions bilaterally.

Use of a Simple Appliance to Prevent Mucosal Irritation by the Distractor Rod during Vertical Distraction: Case Report.

Patient discomfort due to the excessive length of the distractor rod is one of the disadvantages of alveolar distraction osteogenesis. Although this seems to be a minor complication, it can cause severe mucosal irritation on the opposite arch, and uncontrolled forces can lead to the loosening of the screws and the inactivation of the distractor. The purpose of this case report is to introduce an acrylic appliance that is very useful in avoiding the mucosal irritation caused by the long distractor rod.

Fixation of vertically distracted segment with dental implants after breakage of distraction device: case report.

Distraction osteogenesis is an efficient method to augment the mandibular alveolar process for dental implants. Complications of this procedure include fracture of the basal bone, breakage of distractor, wound dehiscenses, undesirable soft tissue changes, and defective movement of the transported segment. We report a case of breakage of the distractor after mandibular alveolar vertical distraction osteogenesis.
