Avulsed teeth that are stored extraorally in a dry environment for >60 min generally develop replacement root resorption or ankylosis following their replantation due to the absence of a vital periodontal ligament on their root surface. One negative sequelae of such ankylosis is tooth infra-positioning and the local arrest of alveolar bone growth. Removal of an ankylosed tooth may be difficult ...

BACKGROUND The purpose of this study is to evaluate the outcomes of four patients receiving stock Biomet TMJ prosthesis for reconstruction of the TMJs. METHODS TMJ reconstruction with stock Biomet TMJ prosthesis was performed in four patients who had joint damages by trauma, tumor, resorption, and ankylosis, which represent the indications of alloplastic prosthesis. RESULTS Loss of condyle ...

An approximately 7-year-old 1.7kg, female Siamese cat with a history of a malocclusion and an inability to open its mouth was referred the Animal Medical Center, Chonbuk National University. The cat had shown signs since it was adopted four years earlier but the cause was not determined. The mandible was deviated 2 mm to left, the mouth could be opened only 2 mm and attempts to open the jaws ca...

This clinical article reports a technique, apicotomy, for managing dilacerated or ankylosed canines. The records of 3 patients successfully treated with apicotomy are presented. Orthodontists observe clinically significant incidences of impacted maxillary canines in their daily practices. Several procedures have been described to bring an ankylosed, impacted tooth into occlusion. Luxation is th...

The treatment of temporomandibular joint ankylosis poses a significant challenge because of the high incidence of recurrence .The only treatment option for TMJ ankylosis is surgical with or without condylar reconstruction. Various grafts are available for condylar reconstruction after removing the ankylotic mass such as costochondral, sternoclavicular, posterior border of mandibular ramus, fibu...

Heterotopic ossification associated with neurologic injury, or neurogenic heterotopic ossification, tends to form at major synovial joints surrounded by spastic muscles. It is commonly associated with traumatic brain or spinal cord injury and with other causes of upper motor neuron lesions. Heterotopic ossification can result in a variety of complications, including nerve impingement, joint ank...

To understand the role of RNA-binding proteins (RBPs) in the regulation of gene expression, methods are needed for the in vivo identification of RNA-protein interactions. We have developed the peptide nucleic acid (PNA)-assisted identification of RBP technology to enable the identification of proteins that complex with a target RNA in vivo. Specific regions of the 3' and 5' UTRs of ankylosis mR...

Temporomandibular joint ankylosis is inability to open mouth due to either a fibrous or bony union between the head of the condyle and the glenoid fossa. It is most commonly associated with trauma, local or systemic infection, tumors or systemic disease such as ankylosing spondylitis, rheumatoid arthritis, or psoriasis. Odontogenic keratocyst as defined by World Health Organization are known fo...

The main cause of decreased mouth opening in patients suffered from trauma is bony or fibrous ankylosis of temporomandibular joint, but other causes such as fibrous or bony union of zygoma and / or maxilla to the coronoid process of the mandible must be considered in preoperative management of such cases. Bony union of the mandible to the maxilla and zygoma is rare. In this report, one case,...
