Methods: The condylar position of 12 TMD patients was observed from CBCT images, and clinically, symptom severity score, mouth opening, and range of motion were compared pre- and post-treatment. Results: All patients reported a statistically significant decrease in the symptom severity score and increase in mouth opening and range of motion (p < .05). A significant decrease was only achieved in the left anterior joint space (p < .05). Conclusion: Deprogramming splint therapy and occlusal equilibration benefitted patients with a reduction in clinical symptoms, and minor changes in condylar position were observed.","PeriodicalId":162405,"journal":{"name":"CRANIO®","volume":"7 12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128781876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each procedure was performed by three different evaluators. The values obtained were calculated using the Technical Error of Measurement (TEM) and the inter-evaluator Coefficient of Variation (CV). Results: The mean values obtained were 4.3 mm, 2.2 mm, and 2.6 mm for absolute TEM; 8.7%, 5.4%, and 6.4% for relative TEM; and 7.3%, 4.5%, and 5.6% for CV.

The remaining subjects were followed up without any intervention. After 3 months, the EMG recordings and clinical evaluations were repeated. Results: At baseline, the EMG values at rest and EMG value variations after movements in patients were higher than those in controls. After treatment, no difference was observed between EMG values of patients and controls. Conclusion: In the present study, patients with TMD had abnormal muscular activities. The stabilization splint is effective for functional recovery of the masticatory muscles, possibly by eliminating the CR-MI discrepancy and establishing anterior/lateral guidance.","PeriodicalId":162405,"journal":{"name":"CRANIO®","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125384276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lunn, Editor in Chief of CRANIO, has been the catalyst for the interest in and growth of TMJ and, ultimately, dental sleep medicine. For years, Dr. Lunn and his staff have produced the CRANIO Journal. It began as CRANIO: The Journal of Craniomandibular Practice and, subsequently, became CRANIO: The Journal of Craniomandibular and Sleep Practice. Many brilliant colleagues and authors from all over the world have contributed to this wealth of information related to the two intertwined subjects: TMJ and OSA (temporomandibular joint disorders and obstructive sleep apnea). Now, in the middle of 2019, we continue making strides, moving forward in this most interesting area of dentistry. Dental clinicians are presented with patients of various needs. The general dental supervision of the patient, requiring hygiene and dentition management, is the most fundamental element. Beyond that are the multiple disciplines within dentistry and dental sleep medicine that have rapidly accelerated through the needs of patients and through dentist recognition. Like most of you, I am a clinician, but I am also an educator. After 13 years of occlusal and restorative dentistry, I limited my practice to the diagnosis of head, neck, and craniofacial pain and temporomandibular disorders and, ultimately, dental sleep medicine. I’ve also been afforded hundreds of opportunities to present educational programs relative to these subjects. Development of the temporomandibular joint plays an important role in the development of the airway. The converse is also true [1]. Particularly if present before and during puberty, nasal airway breathing obstruction may result in craniofacial (skull or jaw) deformities [2]. This explains, in part, why we find a strong correlation between patients who suffer from TMJ pain and dysfunction and patients who have sleep-disordered breathing problems including, but not limited to, snoring, sleep bruxism and obstructive sleep apnea. Additionally, like temporomandibular disorders, all too often sleep-disordered breathing goes undiagnosed and, therefore, untreated [3]. The fields of sleep medicine and dental sleep medicine need to solidify a model for the relationship between the medical field and the dental field [4]. There has been great progress since 2013, but there continues to be a need. The prevalence of OSA in America is comparable to the diseases of asthma and diabetes, affecting 25 to 30 million people. We know that it is slightly more common in males than females and progressively worsens with age. The nine identified Sleep Disorders are: Primary Snoring, Upper Airway Resistance Syndrome (UARS), Central Sleep Apnea, Sleep Bruxism, Parasomnias, Restless Leg Syndrome, Narcolepsy, Insomnia and Obstructive Sleep Apnea (OSA). These nine are not mutually exclusive and can interrelate with one another to create a more difficult case [5]. Obstructive Sleep Apnea is defined as “cessation of airflow for greater than 10 seconds with contin","PeriodicalId":162405,"journal":{"name":"CRANIO®","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122381811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They asked me to see patients before they went to surgery to make sure the surgery was appropriate. These patients had been diagnosed with Temporomandibular Disorder “TMD” [1] and treated by an experienced “TMD” dentist who was director of the “TMJ” clinic that was part of the insurance company’s HMO. After standard treatment with intraoral appliances [2] and physical therapy, these patients were sent to an oral surgeon for surgery to treat their “TMD.” Most of these patients were treated with “stabilization” appliances, which are well-referenced in the literature as being effective for treatment of “TMD” [2–4]. They also received physical therapy and medications. I saw about 100 of these patients to evaluate the need for surgery, and after thorough evaluation and specific diagnosis, a more specific treatment plan was formulated. After treatment for the specific diagnosis that included the use of appliances designed to orthopedically reduce loading in specific areas of the TMJ, very few needed surgical intervention and had excellent results. TMD is meant to be a general term for all disorders relating to the temporomandibular joint and related structures [1,5]. Unfortunately, much of the literature is focused on the diagnosis and treatment of “TMD” instead of evaluating the treatment of specific conditions that make up this catch-all diagnosis. Some of the major diagnostic categories that are included in the term “TMD” include, but are not limited to, the following:","PeriodicalId":162405,"journal":{"name":"CRANIO®","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132130187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results: All patients had crackling in the joint, a habit of grinding teeth during sleep, muscle stiffness, and tinnitus. The tomographic findings revealed a higher frequency of condylar bone wear, reduction of joint space, and posterior positioning of the mandibular condyle.
