Patient-Fitted Temporomandibular (TMJ) Right Mandibular Component part of TMJ Reconstruction Prosthesis System. Model /catalog # TYY-NNNNRM The TMJ Concepts Patient-Fitted TMJ Reconstruction Prosthesis System is intended to be used for the reconstruction of the temporomandibular joint. It is indicated for patients with one or more of the following conditions: ¿ Inflammatory arthritis involving the temporomandibular joint not responsive to other modalities of treatment ¿ Recurrent fibrous and/or bony ankylosis not responsive to other modalities of treatment ¿ Failed tissue graft ¿ Failed alloplas...

A subset of temporomandibular joint (TMJ) disorders is attributed to joint degeneration. The pig has been considered the preferred in vivo model for the evaluation of potential therapies for TMJ disorders, and practical considerations such as cost and husbandry issues have favored the use of young, skeletally immature animals. However, the effect of growth on the biochemical and biomechanical properties of the TMJ disk and articulating cartilage has not been examined. The present study investigates the effect of age on the biochemical and biomechanical properties of healthy porcine TMJs at 3, 6, and 9 months of age. DNA, h...

A retrospective study was performed to determine the efficacy of a tethering procedure developed to achieve a more rigid fixation and more reliable outcome in patients with refractory dislocation of the temporomandibular joint. The cases of eight patients with dementia and systemic diseases who underwent this technique were reviewed. In these eight patients, the condyles of 13 joints were ligated using wire between screws placed in the eminence and condylar head. Additional screw –wire ligations were applied to reinforce the restraint of movement in five of the 13 joints with suspected uncontrolled dislocation.

CONCLUSION: Participants in the group with class II hyperdivergent patterns have a smaller and narrower condyle compared with the other groups measured. Asymmetry was found among all groups, with participants with skeletal class III patterns having the most asymmetry. The most common condylar morphology in all groups examined was convex. PRACTICAL IMPLICATIONS: These results support the concept that morphology and symmetry of the temporomandibular joint varies in different skeletal patterns, presumably as an adaptive response to functional demands.

CONCLUSIONS: The authors recommend psychological assessment at first intake of a new adult patient or for patients with persistent TMD pain. The authors recommend the pain-related disability screening tools for all TMD pain symptoms and for dental pain symptoms that persist beyond the normal healing period. PRACTICAL IMPLICATIONS: A brief psychological and pain-related disability assessment for patients in primary care may help the general oral health care practitioner make tailored treatment decisions.

Discussion Oropharyngeal trauma is common and ranges from minor contusions to severe trauma of the head and neck. Sudden movement while having a foreign object in the mouth is a very common scenario with falls or collisions being common mechanisms. Common objects include toys, sticks, pens/pencils, chopsticks, toothbrushes, and popsicle sticks. Many of these injuries cause minimal problems such as a contusion to lips (i.e. “fat lip”). In general, the more anterior the location the more common the injury and the less likely to have a severe injury (i.e. lips). Whereas posterior structures are more protected, bu...

The objective of the present study was to evaluate the effect of orthognathic surgery on temporomandibular disorder (TMD) in patients with skeletal class III malocclusion. Study design: Forty-seven patients undergoing surgery were evaluated using Axis I of the Research Diagnostic Criteria/TMD index by a trained examiner, consecutively, at three different periods: 1 week before operation (T0), 6 months after operation (T1), and 1 year after operation (T2). Bivariate analyses were performed to compare the evaluation periods (p

AbstractIntroductionThe aim of this study was to three-dimensionally analyze the net skeletal, dental, and temporomandibular joint (TMJ) treatment changes using Twin Block functional therapy in comparison to untreated subjects.Materials and methodsThe study (Twin Block) group comprised 22  female patients with skeletal Class II malocclusion due to mandibular retrusion. A total of 18 skeletal Class II untreated female subjects were included as controls. Skeletal, dental, and TMJ changes were evaluated using pre- and posttreatment/observational by cone beam computed tomography (CBC T) images. The treatmen...

Publication date: April 2018 Source:The Kaohsiung Journal of Medical Sciences, Volume 34, Issue 4 Author(s): Chih-Ling Chang, Ding-Han Wang, Mu-Chen Yang, Wun-Eng Hsu, Ming-Lun Hsu Temporomandibular joint (TMJ) is one of the most complex joints of the human body. Due to its unique movement, in terms of combination of rotation and translator movement, disc of the joint plays an important role to maintain its normal function. In order to sustain the normal function of the TMJ, disc must be kept in proper position as well as maintain normal shape in all circumstances. Once the disc is not any more in its normal position duri...

Authors: Fabbri G, Sorrentino R, Cannistraro G, Mintrone F, Bacherini L, Turrini R, Bombardelli T, Nieri M, Fradeani M Abstract This multicenter retrospective clinical study was aimed at comparing the effects of an increase in vertical dimension of occlusion (VDO) in patients with fixed rehabilitations. Expert clinicians retrospectively evaluated 100 patients treated with an increase of the VDO and fixed dental prostheses (FDPs) supported by teeth, implants, or both. The patients were divided into three study groups according to the type of support of restorations in posterior areas, as follows: partially edentulou...
