Abstract

The temporomandibular joint is part of the stomatognathic system, where interference with one component of the stomatognathic system will interfere with other components causing an imbalance of function. One such disorder is temporomandibular. Temporomandibular disorders have signs, symptoms, and severity that can be eliminated through jaw exercises. This study had the goal of evaluating and comparing the severity of TMD symptoms between students before and after engaging in jaw exercises In this purposive sampling study, researchers used questionnaires based on the Helchymo Anamnestic Index. 30 respondents who complained of temporomandibular disorder were asked to fill out a questionnaire through a Google form. Patients with TMD were inferred based on the total score of all questions with paired T-test statistical results. The results showed that there was a difference in severity before and after jaw exercise in 24 (80%) patients. There was a difference in the severity of temporomandibular joint disorders before and after jaw exercise by patients with p-value = 0.0001 (p <0.005).

Abstract

ABSTRACT Implant-supported fixed partial dentures (iFPDs) are used for posterior rehabilitation. Biomechanical problems arise in the posterior due to complicated occlusal stresses and insufficient bone support. Prosthetic design and material stiffness affect stress distribution on peri-implant bone and components, affecting iFPD success. This systematic review examined the biomechanical performance of zirconia, PEKK, and PEEK two- and three-unit iFPDs with fixed-fixed and cantilever designs. FEA was used to evaluate stress distribution and clinical implications. PICO criteria and Boolean operators were used to search PubMed, Scopus, ScienceDirect, and MyEBSCO for 2020–2025 studies. Five of 158.353 documents met PRISMA 2020 criteria. Von Mises stress, prosthesis configurations, material stiffness, and stress concentration zones were extracted. Cantilever designs had the highest stress values, especially at the connector and prosthesis-abutment interface. Due to its stiffness, zirconia shielded the peri-implant bone, while PEKK and PEEK reduced prosthesis stress but transferred more stress to the bone. Connectors were the most biomechanically susceptible in all designs and materials. The synergistic interplay between prosthetic design, material mechanical properties, and loading direction determines the stress distribution pattern and long-term stability of implant-supported prosthetic structures.

Abstract

Background: Severe mandibular alveolar ridge atrophy, common in geriatric patients, compromises the functional success of complete dentures due to a reduced denture-bearing area and the proximity of muscle attachments to the ridge crest. This condition increases denture displacement during function in both horizontal and vertical movements, leading to poor retention and stability of the denture. Accurate impression techniques are critical to overcoming these challenges. The closed-mouth functional impression technique allows for the recording of denture-bearing areas and peripheral seal under functional pressure, potentially enhancing retention.Objective: This case report aims to describe the procedure for fabricating a complete denture using a modified custom tray with a closed-mouth impression on a fully edentulous, compromised mandibular flat ridge.Case Report: A 52-year-old woman presented with a loose and poorly fitting lower denture. Clinical examination revealed complete edentulism with a severely resorbed mandibular ridge. A custom tray was fabricated with a detachable handle to support the closed-mouth impression technique without interfering with occlusion during border molding and impression-making. The closed-mouth approach allowed for better muscle molding, recording of functional borders, and a more accurate reflection of the patient’s oral dynamics. As a result, the final denture exhibited significantly improved retention and comfort during function. This case highlights the clinical advantage of the closed-mouth impression technique in managing challenging ridge conditions and emphasizes the practical benefit of modifying tray design to ease the procedure for both clinician and patient. Such adaptation is especially relevant in geriatric care, where functional and anatomical limitations are common.Conclusion: The use of a modified custom tray with the closed-mouth functional impression technique proved effective in managing a severely resorbed mandibular ridge. It resulted in a stable, retentive, and comfortable complete denture, contributing to enhanced patient satisfaction.

Abstract

ABSTRACT Background: Temporomandibular disorders (TMD) can result from stress, occlusal imbalance, trauma, and poor posture. Stress often triggers parafunctional habits such as clenching, leading to masticatory muscle hyperactivity, fatigue, stiffness, and pain radiating to the head and other body regions. Conservative therapies include splints, yoga, and cognitive behavioral therapy (CBT). Objective: To report the management of a TMD case diagnosed as myofascial pain with spreading and arthralgia using a combination of stabilization splint, face and full-body yoga, and smartphone-based CBT. Case Report: A 28-year-old female presented with muscle pain radiating to the head, neck, and lower back, and limited mouth opening. She had a history of clenching. DC/TMD Axis I confirmed myofascial pain with spreading and arthralgia; Axis II showed mild depression (score = 6). Treatment comprised a stabilization splint, face and full-body yoga, and smartphone-based CBT over six weeks. Post-treatment, mouth opening increased from 25 mm to 33 mm, depression score decreased to 1, and muscle tension was significantly reduced. The patient reported improved quality of life and awareness of parafunctional habits. Conclusion:A multidisciplinary approach integrating splint therapy, yoga, and smartphone-based CBT effectively reduces TMD symptoms. Splints and yoga relax muscles, while CBT enhances stress management and awareness of clenching, contributing to therapeutic success.
