An appliance for management of TMJ pain as a complication of Parkinson's disease.

This is a case report of a 71-year-old female with pain in the right TMJ, who was also suffering from Parkinson's Disease and was treated using a new intraoral occlusal appliance. The new appliance was designed to limit excessive mandibular excursion of the right side by restricting the mediotrusive movement of the left coronoid process. The appliance significantly suppressed involuntary mandibular excursion.

Temporomandibular treatment outcomes within five diagnostic categories.

This study of temporomandibular disorder (TMD) treatment outcomes examines 274 consecutive patients in five diagnostic categories and a 25 patient comparison group to determine relative levels of symptom improvement. Employing a psychometric outcome measure, the TMJ Scale, it was found that patients receiving active TMD treatments manifest statistically significant symptom improvements. Untreated patients reported minor and statistically insignificant symptom variations. Patients with intracapsular TM joint dysfunctions exhibited higher levels of improvement in pain and other TMD symptoms than patients presenting with primarily muscle symptoms. This research supports the hypothesis that TMDs are not self-limiting and require active treatment interventions. It is suggested that some studies cited to show that TMDs are self-limiting have major methodological limitations, relying upon unvalidated and subjective assessments of symptom levels. This research also outlines a procedure for TMD practitioners to measure treatment efficacy and the relative effectiveness of differing treatment modalities in a valid, consistent and unbiased manner.

Phase II therapy for a chronic pain patient: a clinical report.

One of the roadblocks to success in treating temporomandibular joint dysfunction (TMD) patients is an accurate diagnosis. The terms "TMJ" or "TMD" are not specific enough to provide definitive treatment. Initially the disorder must be classified as a muscular or an internal derangement problem. Once accomplished, the further diagnostic breakdown of the problem will prepare the patient and the doctor for the scope of treatment necessary and the prognosis. This lack of a specific diagnosis can lead to inappropriate treatment and inadequate communication among clinical dentists, academia and patients. Our patients and the profession will continue to suffer until a single diagnostic system is universally agreed upon and utilized.

A new survey instrument: a sample of a typical TMD practice.

The study evaluated 646 patients treated in a full time TMD practice with a new survey tool based on a patient self-report questionnaire. It would appear that this new approach to practice evaluation has not been previously reported in the literature. The results indicate that the average patient has a significant time delay of 24 to 120 months from onset of symptoms to the beginning therapy and that the majority of patients see three or more practitioners before reaching the TMD therapist. Most significantly, there are strong indications that early intervention and persistent compliance with prescribed therapy produces the highest level of success. Valuable practice statistics regarding patient treatments, patient outcomes and modalities of therapy have proven intensely useful in managing the patients, educating the public, communicating with the referral base, as well as in negotiating participation agreements with managed care institutions.

Regeneration ad integrum of the condyle head in a patient with temporomandibular disorders.

A 14-year-old who had suffered from a beta-hemolytic streptococcus infection presented with serious temporomandibular disorders, including a reabsorption of the condyle head on the right side, and reabsorption in the cavern of the left side. Her masticatory muscles were electronically deprogramed, achieving a mandibular position supported by a relaxed musculature. The patient's signs and symptoms subsequently disappeared. Study of the magnetic resonance image a year later clearly showed a regeneration ad integrum of the condyle head and a spontaneous reinsertion of the articular disk. The results suggest the need for use of electronic elements in order to treat patients with temporomandibular disorders effectively.

Sliding plates on complete dentures as a treatment of temporomandibular disorder: a case report.

This work presents a case report of a woman, aged 62, who presented with signs and symptoms of temporomandibular disorder (TMD). The patient reported pain in the masticatory system and examination showed a reduction in the occlusal vertical dimension (OVD). She was treated with complete dentures incorporating a modification to the posterior regions developed by the authors and which were termed "sliding plates." Through analysis of photographs taken of the patient prior to the extraction of the patient's natural dentition, sliding plates were utilized to reestablish the OVD. The sliding plates also allowed for unrestricted eccentric mandibular movements, thereby accelerating the neuromuscular deprogramming and making it possible for the mandible to adopt a more physiologic position. The dentures reduced the pain and were well-accepted by the patient. Therefore, sliding plates may be of great benefit to completely edentulous patients with painful symptoms that result from alterations in the OVD and inappropriate condylar positioning.

Effects of a mandibular advancement device for the treatment of sleep apnea syndrome and snoring on respiratory function and sleep quality.

In this study the fabrication of a simplified mandibular advancement device for sleep apnea syndrome was described. Its effect on respiratory function and sleep quality variables was evaluated polysomnographically in 256 patients with sleep apnea syndrome and snoring. Polysomnographic recordings were performed twice, before and after insertion of the oral appliance. The mean apneahypopnea index (AHI) decreased significantly (p < 0.0001) with the appliance to 18.2 from 43.2 without it. Responders defined by AHI < 10 were 54% and those defined as a 50% decrease of AHI were 66%. Oxygen saturation, duration of apnea, sleep efficiency, and total arousal were improved significantly after treatment without major side effects. The device improved significantly the respiratory function and sleep quality in patients with sleep apnea syndrome. Compliance was about 90% followed for 2.5 years. This appliance offers some advantages over other therapies because it is noninvasive, easy to fabricate, and well accepted by patients.

A trigeminal neuralgia-like paroxysmal pain condition presumably due to buccal nerve compression in the temporalis muscle.

We encountered three patients with trigeminal neuralgia-like paroxysmal pain in the buccal nerve region. In all cases, paroxysmal pain was felt spreading to the receptive field of the ipsilateral buccal nerve, and clear tenderness was observed during intraoral palpation at the inner side of the mandibular ramus where the temporalis muscle runs and attaches. It was assumed that the paroxysmal pain might be caused by nerve compression related to temporalis muscle hyperactivity. To lend support to this hypothesis, we also studied the anatomical relationship between the buccal nerve and the masticatory muscles. In this autopsy study, the buccal nerve pierced the temporalis muscle in six (12%) of 52 specimens from 26 cadavers. These findings support the hypothesis that peripheral buccal nerve compression could be an etiology of paroxysmal neuropathic pain in the unilateral orofacial region.

Tooth wear: use of overlays with metallic structures.

This work is a clinical case report of a patient presenting with marked tooth wear in all teeth, a reduction in the vertical dimension of occlusion, and fatigue in the muscles of mastication. The treatment proposed and effected used a muscle-relaxing appliance and mandibular and maxillary overlay appliances which were adjusted according to the occlusal contacts, vertical dimension of occlusion, and the mandibular positioning. The results obtained were satisfactory in terms of relaxing the muscles involved, reestablishing the dimensions of the lower third of the face, and the functional activities of deglutition, mastication, and speech.

The effects of a home exercise program on pain and perceived dysfunction in a woman with TMD: a case study.

There are few reports analyzing the effects of exercise on patients with temporomandibular disorders. This paper presents a case study examining whether there were additional benefits from performing neuromuscular control home exercises (NMCHE) in a patient with temporomandibular disorder who was already receiving conventional treatment. A woman, 41 years of age, completed a health status questionnaire called the TMJ Scale prior to being accepted. She completed additional TMJ Scales after receiving conventional treatment and again after conventional treatment was combined with neuromuscular control home exercises. Based on the TMJ Scale's best subscore indicator of the presence or absence of a temporomandibular disorder, the patient did not derive benefit from conventional treatment without exercise. However, she received a large benefit from the addition of NMCHE. It was concluded that exercises for patients with temporomandibular disorders may be beneficial to those who do not improve with conventional treatment alone.

Posterior disk displacement of the TMJ: MRI evidence in two cases.

Posterior disk displacement is a rare temporomandibular joint (TMJ) disorder. The main clinical sign is sudden molar open-bite (jaw locked in the open position). This may be accompanied by a sensation of intra-articular foreign body and more rarely joint pain. Joint sounds are unremarkable. Mouth opening may be slightly impaired. Hypothetically, like anterior disk displacements, posterior disk displacements can be classified as either reducible or nonreducible. A definitive diagnosis requires magnetic resonance imaging (MRI). There is no consensus concerning treatment. A conservative course of treatment can be successful in patients with functional impairment and should always be attempted before irreversible, invasive therapy.

Treatment received, treatment demand, and treatment need for temporomandibular disorders in 35-year-old subjects.

An epidemiological sample of 114 subjects was followed longitudinally from the age of 15 to 35 years with regard to treatment received, treatment demand, and treatment need for temporomandibular disorders (TMD). Some kind of TMD treatment had been provided to 18% of the subjects during the 20-year follow-up period. Eighty-five percent of those who had received previous TMD treatment reported that the treatment had had a positive effect on their symptoms. The estimated present need for treatment was 11%, but, in line with several other investigations, the active demand for such treatment was much less (3%). From age 15 to 25 years, a small but gradual increase of clinical signs of dysfunction was found. From the age of 25 to 35 years, however, a significant reduction of such signs was noted. One explanation for this reduction of clinical signs and symptoms of TMD might be the stomatognathic treatment received. It was concluded that 18% of the subjects had received some TMD treatment during the 20-year follow-up period. Only 3% still had a demand for such treatment at age 35.

Effect of arthrocentesis on TMJ disturbance of mouth closure with loud clicking: a preliminary study.

The objective of this study was to evaluate the short-term effect of arthrocentesis on temporomandibular joint disturbance of mouth closure with loud clicking compared to the effect of one-time pumping into the joint space previous to arthrography. Twenty-one consecutive patients (22 joints) with loud clicking during mouth closure were enrolled. All were unable to smoothly close the mouth without effort. Eleven patients (12 joints) were examined using magnetic resonance imaging (MRI) to determine disk position. They then underwent arthrocentesis. Ten patients (10 joints) underwent arthrography alone as controls. Six months later, changes in clicking and temporomandibular joint movement were analyzed and the disk position was re-examined. There was improvement of mouth closing and clicking occurred in nine joints from the arthrocentesis group and two joints from the control group, with a significant difference between the two groups. Arthrocentesis may be indicated for patients with temporomandibular joint dysfunction and loud clicking when mouth closing.

Effect of a passive jaw motion device on pain and range of motion in TMD patients not responding to flat plane intraoral appliances.

This study was designed to compare the effectiveness of a passive jaw motion device, the Therabite, and wooden tongue depressors (WTD), in patients with temporomandibular joint and muscle disorders, who did not improve after manual manipulation of the mandible and flat bite plane therapy. Forty-three patients were enrolled in the study and were classified as joint or muscle groups according to the Research Diagnostic Criteria for TMD. Twenty-four were assigned to the joint group, and 19 patients were assigned to the muscle group. The patients were assigned at random to three treatment subgroups: 1. passive jaw motion device therapy (Therabite); 2. wooden tongue depressors therapy (WTD); and 3. control group. All subjects received flat bite plane appliance therapy throughout the treatment period. Mandibular range of motion was measured for maximum opening (MO), right and left lateral (Rt. Lateral, Lt. Lateral) and protrusive (Pr) movements. Pain level was also assessed at the beginning and at the end of the treatment. The results suggested that a passive jaw motion device is effective in increasing range of motion in both groups of temporomandibular disorder patients, joint (intracapsular) and muscle (extracapsular). It also appears to decrease pain in patients with temporomandibular disorders. Pain was relieved to a greater degree in the muscle group than the joint group.

The use of an oral exercise device in the treatment of muscular TMD.

Forty-five patents with a primary diagnosis of muscular MD were evaluated and treated in a university based facial pain center. The patients were equally and randomly assigned to one of three treatment groups. Group 1 patients were treated with traditional therapies appropriate for the particular patent. Group two patients used similar therapies that were appropriate for the patient but also had an oral vertical exercise device integrated into their therapy. Patients in the third group were instructed in home care, educated about TMD, and instructed in the use of the oral exercise device. Results indicated that all three groups demonstrated significant overall patient clinical and subjective improvement. The three groups did not differ significantly from each other in degree of patient improvement.

The effect of stepwise increases in vertical dimension of occlusion on isometric strength of cervical flexors and deltoid muscles in nonsymptomatic females.

This mixed, single-double blind study examined the effect of a stepwise increase in vertical dimension of occlusion (VDO) on the isometric strength of cervical flexor and deltoid muscles in 20 asymptomatic females with deep bite (age range 20-40 years). Vertical dimension of occlusion was increased by mandibular acrylic bite plates, 2, 4, 6 and 12 mm. Subjects were instructed to bite while resisting: 1. an increasing horizontal force was applied to the forehead; and 2. an increasing vertical downward force to the wrist of each extended arm. Forces were applied by a hand-held strain gauge until resistance yielded. The force applied at the point of yielding was recorded as isometric peak strength of that trial. The peak strength for each muscle group was measured twice and averaged to produce a mean peak strength measure. This procedure was repeated in the subject's habitual occlusion and for the four increased VDOs. Mean strength of cervical flexors with increased VDO (12.0 kg) was significantly greater than that for existing vertical dimension occlusion (9.6 kg). With the exception of pre-experimental existing VD of occlusion, strength for right and left deltoids did not differ, but mean deltoid strength in the increased condition (8.6 kg) was significantly greater than biting in without a bite plate (6.6 kg). In the peak condition, cervical flexor strength increased 24% and deltoid strength increased an average of 29% from that of biting without an increase. As VDO increased further, strength in all sites was found to diminish. Repeating the strength test without a bite plate, after all trials were administered, did not show differences from pre-experimental levels, indicating that fatigue was not an important factor. The findings demonstrate that isometric strength of the cervical flexors and deltoids increases significantly from habitual occlusion as the VDO is increased, then diminishes as VDO is increased further. The strength of both cervical flexors and deltoids varied in concert with changes of VDO.

Symptom relief after treatment of temporomandibular and cervical spine disorders in patients with Meniere's disease: a three-year follow-up.

This study describes the coordinated treatment of temporomandibular disorders (TMD) and cervical spine disorders in patients diagnosed with Meniere's disease. The aim was to follow up treatment outcomes for three years with regular follow-up examinations every six months. Of the 31 patients with Meniere's disease who participated in a controlled comparative study on the signs and symptoms of TMD, 24 participated in a subsequent controlled comparative study on the signs and symptoms of cervical spine disorders (CSD). These 24 Meniere's disease patients (ten males and 14 females) agreed to participate in this longitudinal study. At each follow-up, their symptoms were evaluated using self-administered questionnaires and visual analog scales (VAS). The results of the coordinated treatment showed simultaneous decreases in the intensities of vertigo, nonwhirling dizziness, tinnitus, feeling of fullness in the ear, pain in the face and jaws, pain in the neck and shoulders, and headache that were both longitudinal and highly significant. Significant longitudinal reductions in the frequencies of vertigo, nonwhirling dizziness, and headache were also reported by the patients as well as a complete disappearance of pain located in the vertex area. A significant relief of TMD symptoms and a decrease in nervousness was also achieved. The results showed that a coordinated treatment of TMD and CSD in patients with Meniere's disease is an effective therapy for symptoms of this disease. The results also suggested that Meniere's disease has a clear association with TMD and CSD and that these three ailments appeared to be caused by the same stress, nervousness, and muscular tension.
