1/9. The incidence and influence of abnormal styloid conditions on the etiology of craniomandibular functional disorders.This study aimed to examine the incidence and influence of craniomandibular functional disorders caused by abnormal styloid-stylohyoid chains. Seven hundred sixty-five patients with temporomandibular joint (TMJ) disorders were divided into two groups (with and without radiographically visible abnormal styloid conditions). In the group with abnormal stylohyoid conditions, the etiology of TMJ disorders was further subdivided into poly-, oligo- and monoetiological factors, and, after this classification, evaluated regarding a clear, possible or unlikely involvement of abnormal stylohyoid conditions in TMJ disorders. One hundred thirty-six out of 765 patients presented abnormal styloid-stylohyoid chains. One hundred five of the patients (77.2%) demonstrated polyetiological causes of TMJ symptoms with an unlikely involvement of the abnormal styloid-stylohyoid chain. Twenty-nine of the patients (21.3%) showed oligoetiological causes with possible involvement of the abnormal styloid-stylohyoid chain. In two patients (1.5%), the abnormal styloid conditions showed up as the only definite cause of TMJ symptoms (monoetiological). Detailed knowledge of variations and possible effects of suprahyoid structures is important for an accurate diagnosis of TMJ disorders. All in all, the incidence of a stylohyoid involvement in TMJ disorders is very low. However, after an initial subdivision into abnormal and normal stylohyoid conditions, the incidence of pathological stylohyoid chains gains significant importance in the etiology of TMJ disorders.- - - - - - - - - - ranking = 1keywords = craniomandibular (Clic here for more details about this article) |
2/9. Stabilization of the craniomandibular therapeutic relationship with etched porcelain bonded restorations: a clinical report.The major advantage of this technique is sustaining the preexisting therapeutic position of the mandible during the restorative phase with minimal error in the occlusal scheme despite the type of restorative material. This clinical report demonstrated the conservative nature of bonding etched porcelain to tooth structure while concomitantly stabilizing the mandible to the maxillary dental arch.- - - - - - - - - - ranking = 0.8keywords = craniomandibular (Clic here for more details about this article) |
3/9. Increased overbite and craniomandibular disorders--a clinical approach.This study investigated the effect of a maxillary fixed lingual arch with anterior bite plane on adult patients with craniomandibular disorders (CMD) and increased overbite. The sample comprised 11 patients with an increased overbite (greater than 5 mm) and a normal or Class II molar relationship. The main CMD symptoms were daily tension headache in the region of anterior temporal muscles and/or pain or clicking in the temporomandibular joint. Previous treatment with stabilization splints, removal bite plates, or occlusal grinding had not given satisfactory results. When the maxillary lingual arch with anterior bite plane was fitted, molar separation was approximately 4 mm, and occlusal contact occurred only between the acrylic bite plane and the lower six anterior teeth. The permanent appliance could be removed only by the orthodontist. All patients reported relief of CMD symptoms 1 to 2 weeks after initiation of treatment. After a mean time of 3 months, a flatter curve of Spee, molar contact, and reduced overbite could be seen in all cases. The excessive overbite had decreased approximately 3.4 mm. Subsequent treatment involved orthodontic or prosthetic therapy to normalize and stabilize the sagittal and vertical dimensions. After an average posttreatment observation period of 2 years, all patients remained free of CMD pain.- - - - - - - - - - ranking = 3.3369751353455keywords = craniomandibular disorder, craniomandibular (Clic here for more details about this article) |
4/9. temporomandibular joint osteoarthrosis and internal derangement. Part I: Clinical course and initial treatment.A certain natural sequence exists in the occurrence of the major clinical symptoms of 'craniomandibular dysfunction', usually leading to a final stage in which the disease is burned out. Most clinical symptoms can be explained by an internal derangement. As long as we do not know the real cause of, and the exact relationship between, osteoarthrosis and internal derangement, management should be primarily directed at the symptoms. In this paper, the major stages of the disorder are described and illustrated with three characteristic cases.- - - - - - - - - - ranking = 0.2keywords = craniomandibular (Clic here for more details about this article) |
5/9. lyme disease misdiagnosed as a temporomandibular joint disorder.craniomandibular disorders cause many pleomorphic and seemingly unrelated clinical manifestations that mimic other more serious medical problems and thus can present physicians and dentists with a challenge that invites misdiagnosis and improper treatment planning. Conversely, misdiagnosis and ineffective treatment planning are facilitated when serious medical problems manifest a range of signs and symptoms that are clinically similar to temporomandibular joint muscle dysfunction. At times, the patient's response to therapy may be the best method of corroborating a diagnosis, as illustrated in this report of a patient with lyme disease that was misdiagnosed as a temporomandibular joint disorder. lyme disease has already reached epidemic proportions in several parts of the united states and its geographic distribution is spreading. Because lyme disease is a life-threatening illness whose clinical manifestations can mimic temporomandibular joint/myofascial pain-dysfunction, it is the responsibility of every dentist who treats craniomandibular disorders to become familiar with the clinical presentations of lyme disease and more proficient in its differential diagnosis.- - - - - - - - - - ranking = 0.6673950270691keywords = craniomandibular disorder, craniomandibular (Clic here for more details about this article) |
6/9. Documented instance of restored conductive hearing loss.The relationship between temporomandibular joint dysfunction and hearing disorders has long been recognized by some healthcare providers (1,2). Fonder reports that "chronic low-grade otitis media is a constant finding in patients who have a disturbance of the stomatognathical structures due to malocclusion" (3). Fingeroth stated that "a constricted maxillary dental arch frequently results in a decrease in nasal permeability...and within this environment a conductive hearing loss may be present" (4). Histological studies confirm the intimate relationship between the TMJ, the tympanic cavity and the eustachian tube (5,6). Nevertheless, craniomandibular origins are frequently overlooked in the medical profession as possible causes for hearing problems. The following case illustrates this point.- - - - - - - - - - ranking = 0.2keywords = craniomandibular (Clic here for more details about this article) |
7/9. Application of myofunctional therapy in cases with craniomandibular disorders.Modern technology for diagnosis and treatment planning in the management of craniomandibular disorders is described. Three cases are presented to demonstrate how myofunctional therapy is used to 1) stop the damaging hyperactivity of masticatory and perioral muscles and 2) to restore normal muscle function at rest and for chewing and swallowing.- - - - - - - - - - ranking = 3.3369751353455keywords = craniomandibular disorder, craniomandibular (Clic here for more details about this article) |
8/9. Muscular "modus agendi" and craniomandibular dysfunction.It is very important to analyze the muscular "modus agendi" in diagnosing and treating dysfunctional problems. By identifying, then changing, the abnormal muscle posture and function, we are able to correct the muscular pathology and to start orofacial orthopedic treatment without the presence of dysfunctional counterforces.- - - - - - - - - - ranking = 0.8keywords = craniomandibular (Clic here for more details about this article) |
9/9. Cluster-like signs and symptoms respond to myofascial/craniomandibular treatment: a report of two cases.Two cases with pain profiles characteristic of cluster-like headache, both within and outside the trigeminal system, are reported. One male patient would typically awaken from sleep with severe unilateral temporal head pain and autonomic signs of ipsilateral lacrimation and nasal congestion. A female patient exhibited severe unilateral boring temporal and suboccipital head pain with associated ipsilateral lacrimation and rhinorrhea. In addition, both patients presented with signs and symptoms of masticatory and/or cervical disorders. These two cases illustrate possible treatment alternatives, as well as possible influences from cervical and masticatory structures in the development of cluster or cluster-like headache.- - - - - - - - - - ranking = 0.8keywords = craniomandibular (Clic here for more details about this article) |
