In the article the analysis of the changes in the dentoalveolar system occurring with increased abrasion of the teeth is carried out, the features of these changes and the compensatory capabilities of the dentoalveolar system with pathological abrasion are considered. It was concluded that the observed rearrangements on the part of many structures of the maxillofacial region (jaw bones, temporomandibular joint, teeth, muscles) should be established during diagnosis and treatment should be planned taking into account the morphological and functional changes that have arisen on the part of all elements of the dentition, which will help improve the effectiveness of treatment.

Treating oncologic patients remains a challenge for surgeons aiming to provide patients with safe margins of resection while maintaining the highest possible quality of life. The latter, in the case of malignancies, requires using sophisticated methods of reconstruction. Thus, we present a case of a 75-year-old patient treated in our department with a rare neoplasm in the region of the temporomandibular joint—a myxofibrosarcoma that was mimicking an inflammatory lesion. The patient underwent two surgeries—firstly alloplasty of the TMJ due to the suspicion of an inflammatory lesion, lately extended to the resection of glenoid fossa and subtemporal fossa contents when the mandible was reconstructed using UHMW-PE (ultra-high molecular weight polyethylene). The patient was also referred for adjuvant radiotherapy and has remained disease-free for over 96 months with very good aesthetics and function of the mandible. The presented case highlights not only the need for increased oncologic awareness but also the possible use of UHMW-PE as a reconstruction material in the broad resection of the maxillofacial region.

Degeneration of the articulating surfaces and pain associated with temporomandibular joint (TMJ) dysfunction are the primary symptoms of TMJ disorders (TMDs), where normal life activities such as eating, talking, and even sleeping may be drastically impaired [1–3]. To accelerate the discovery of effective therapeutic interventions for the treatment of TMD pain, we have been establishing a novel non-invasive approach for objectively assessing the presence of joint hypersensitivity. Our approach to identify chronic joint pain is based on evidence that all of the etiological factors associated with TMD pain implicate remodeling and degeneration of the joint in response to alterations in motion and loading. The injury model used for this study was a reversible, mechanical model through splint placement on the molars. It is hypothesized that arthrokinematic analysis will identify a specific pattern of functional changes that constitute a signature for the presence of irreversible damage.

Abstract Objective: To determine the influence of masseter muscle activity during growth on the functional characteristics of temporomandibular joint (TMJ) mechanoreceptors. Materials and Methods: Sixty-six 3-week-old male Wistar rats were divided into an experimental group, in which the masseter muscles were bilaterally resected at 3 weeks of age, and a control group. Single-unit activities of the TMJ mechanoreceptors were evoked by indirect stimulation of passive jaw movement. Electrophysiologic recordings of TMJ units were made at 5, 7, and 9 weeks of age. Results: During this period, the firing threshold of the TMJ units was significantly lower and the maximum instantaneous frequency of the TMJ units was significantly higher in the experimental group than in the control group. Conclusion: Reduced masseter activity during the growth period alters the response properties of TMJ mechanoreceptors.
