    Aim: The study aimed to evaluate the effect of implant-supported prosthesis in completely edentulous participants in terms of osseoperception ability, neural activity, and stereognostic ability in comparison to removable prosthetic options. Materials and Methods: A total sample of 18 patients, irrespective of gender and age were allocated into three groups according to the three-treatment protocol (upper and lower complete denture, upper complete denture opposing lower implant-retained overdenture, implant-supported fixed prosthesis in both arches). Four weeks after completion of the treatment procedure active tactile sensibility (ATS) was checked by using varying thicknesses (12, 40, 80, 100, 200 ?) of articulating foils and papers. Functional magnetic resonance imaging (fMRI) was performed to record neurophysiological activity in cerebral cortex in all the participants. Various forms of test pieces (heat cure acrylic resin) were used to evaluate stereognostic ability. Data regarding the neurophysiological activity were analyzed by using Krushkal�Wallis test and p ? 0.05 was considered to be statistically significant. Data from stereognostic ability test procedure and ATS were compared by using chi-squared test and p ? 0.05 was considered to be statistically significant. Results: Statistically significant difference was found in between the articulating foils in terms of true negative responses as the foil thickness increased in participants wearing complete denture in both the arches (p�=�0.004) and implant-supported fixed prosthesis in both the arches (p�=�0.010). Participants in implant-supported fixed prosthesis group showed significantly more activation in primary motor cortex (right side), somatosensory cortex (left side), angular gyrus (both sides), temporal lobe (left) compared to other groups. No significant difference found in thalamus and premotor cortex region in between the participants of different groups. No statistically significant difference found in between the groups in terms of true responses identifying correct shapes. Mean number of correct responses in stereognostic ability test were 4.16 (83.33%), 3.5 (70%), 3.83 (76.66%) for participants of complete denture group, upper complete denture opposing lower implant retained overdenture group, and implant-supported fixed prosthesis group, respectively. Conclusion: Primary motor cortex, somatosensory cortex, and other regions of brain were diffusely activated in participants wearing implant-supported fixed prosthesis in both the arches. Less number of false responses were recorded in participants of implant-supported fixed prosthesis group and upper complete denture opposing lower implant-retained overdenture group in ATS test compared to participants wearing complete denture in both the arches. � 2022 Wiley Periodicals LLC.

    Efficacy of Arthrocentesis and Stabilization Splints in Treatment of Temporomandibular Joint Disc Displacement Disorder Without Reduction: A Systematic Review and Meta-analysis
    (Springer, 2023) Bhattacharjee, Bappaditya; Bera, Rathindra Nath; Verma, Arju; Soni, Romesh; Bhatnagar, Atul
    Background: Temporomandibular joint disc displacement disorders are a group of temporomandibular disorders beside from other inflammatory disorders and growth related disorders of joint. The purpose of this analysis was to evaluate the efficacy of arthrocentesis procedure in comparison with stabilization splints used for disc displacement disorders without reduction. Materials and Methods: A systematic search was done in electronic databases (PubMed, Cochrane Central, Web of Science). In addition to this hand search of references and grey literatures was done. Qualities of randomized controlled clinical trials were assessed by Cochrane�s tool for Systematic Reviews of Interventions and the Newcastle�Ottawa Scale was followed to assess the prospective and retrospective studies. Outcome variables pain (VAS) and maximum mouth opening were assessed by the software review manager 5.03. Results: A total of five studies were included in the review. Three studies showed greater improvement of symptoms in patients of arthrocentesis group in terms of maximum mouth opening, pain (VAS) value. Two other studies found no significant advantage of arthrocentesis over the other treatment protocol. The meta-analysis resulted in statistically significant difference between outcome variables favouring arthrocentesis group (VAS 1�10) (Mean Difference: 3.10; 95% CI 1.74, 4.45; P�?�.00001, Mean difference: 2.00; 95% CI 0.29, 3.71; P = 0.02). Conclusion: Arthrocentesis showed effective result in terms of increase in mouth opening and reduction of pain level compared to stabilization splint and other non-invasive approaches in patients with disc displacement disorders without reduction. Overall, results supported the rationale of using arthrocentesis in patients with disc displacement disorders without reduction. � 2021, The Association of Oral and Maxillofacial Surgeons of India.
