ABSTRACT
Background: 'Temporomandibular joint disorders (TMDs)' denote an umbrella term that includes arthritic, musculoskeletal and neuromuscular conditions involving the temporomandibular joint, the masticatory muscles, and the associated tissues. Occlusal devices are one of the common treatment modalities utilized in the conservative management of TMDs. The indications for the available 'oral splints' or 'oral orthotic occlusal devices' remain ambiguous. Methods: A joint international consortium was formulated involving the subject experts at TMJ Foundation, to resolve the current ambiguity regarding the use of oral orthotic occlusal appliance therapy for the temporomandibular joint disorders based on the current scientific and clinical evidence. Results: The recommendations and the conclusion of the clinical experts of the joint international consort has been summarized for understanding the indications of the various available oral orthotic occlusal appliances and to aid in the future research on oral occlusal orthotics. Conclusion: The use of the oral orthotic occlusal appliances should be based on the current available scientific evidence, rather than the archaic protocols.
ABSTRACT
Purpose Infinitesimal Periangular Pterygomasseteric Transectioning Approach (IPPTA) is a minimal access surgical approach utilized for the management of base fractures of the mandibular condyle. The aim of the study was to evaluate and report the long-term post-operative functional outcome using this surgical access approach. Materials and method A prospective clinical study involving 20 patients was undertaken to evaluate the post-operative functional and aesthetic outcome for the patients that underwent surgery for base fractures of the mandibular condyle using IPPTA. The various parameters assessed were wound healing, marginal mandibular nerve injury, diet intake, mandibular function, and any other complications at twelfth post-operative month. Results IPPTA provided adequate exposure to the condylar base fracture for open reduction and internal fixation (ORIF) and was found to have an uneventful post-operative recovery phase in terms of functional and aesthetic outcomes. Conclusion IPPTA involves utilizing a smaller incision and provides adequate exposure to the condylar base region for ORIF to establish a satisfactory form and function with a predictable outcome.
ABSTRACT
Purpose: Temporomandibular joint (TMJ) sub-luxation can have a significant psycho-social impact on a patients' well-being. Several treatment modalities have been described in the literature for the same. The present study was undertaken to investigate the efficacy of heavy bupivacaine-dextrose prolotherapy (HDP) for the peri-articular tissues, superior joint space and the retro-discal area in the patients with symptomatic chronic sub-luxation. Materials and Methods: A preliminary clinical study was conducted among 60 patients diagnosed with chronic painful sub-luxation of the TMJ. Patients were divided into control group (CG), n = 30, where autologous blood was injected in the superior joint space, peri-capsular tissues and retro-discal area bilaterally as per the predetermined protocol; and the study group (SG), n = 30 patients were administered heavy bupivacaine-dextrose injection bilaterally in the peri-articular tissues, superior joint space and retro-discal area. The efficacy of the treatment was evaluated by assessing pain, maximum inter-incisal opening (MIO), changes in computed tomography scan, magnetic resonance imaging study, number and need for subsequent injections in both the groups. Result: Among the 60 patients, majority of the patients exhibited successful outcome after both the interventions, ABI and HDP. There was statistically significant reduction in recorded pain score with reduced MIO post-treatment. No morphological changes were noted in the condyle in both the groups. No complications were recorded among the study population. Conclusion: HDP is a safe and simple modality for treating symptomatic sub-luxation with predictable clinical outcome. Heavy bupivacaine-dextrose can be considered as a prolotherapeutic agent for symptomatic chronic temporomandibular joint sub-luxation with the pharmacological benefit of local anaesthesia and proliferent delivery through the same injection.
