[Dento-stomato-facial rehabilitation of young patients. Practical alternatives].

The design conception and the technological achievement of every gnato-prosthetic device are conditioned by a minute evaluation of the biological and morphological individualities of each case, the social level of the patient, corroborated with the technological supply. In our study we evaluated different modalities of dento-stomato-facial rehabilitation of young patients with partially reduced maxillary or mandibular dentition. The study was carried out on a group of 12 young patients, 5 males and 7 females, aged between 16-24 years, who presented at the clinic for the treatment of complex functional disorders that occurred as a consequence of the dentition. The fixed mixed gnatoprosthetic therapy for the young patients and teenagers has to be adapted to the surveyed clinical individuality. The success of the therapy is assured by the accurate application of the gnatoprosthetic principles, the accurate achievement of the technological steps, the use of compatible biomaterials according to the dento-stomato-facial features of this age category.

[Relationship between muscular palpation and three dimensional incisal path at border movement of mandible].

Temporomandibular arthrosis was diversified phases of its development as well as complicated mode of its crisis, due to which no concrete clinical diagnostic procedure has been established yet. However, a close relation of occlusal disturbance with the crisis factor is suggested, and assessments have been made in the prosthetic dentistry, setting a viewpoint at the phases of mandibular movement. Particularly, incisal path at border movement of mandible is made the object for basic assessment since it exhibits intensified condition. On the other hand, importance is attached to Krogh-Poulsen's muscular palpation for diagnosis of the pain and contraction of the masticatory muscle which occur in temporomandibular arthrosis. However, though there is a close relation between the pain or abnormal contraction of the masticatory muscle and the phases of mandibular movement, these diagnostic procedures have been the studies which have dealt with the subjects separately. And no report is seen on the study made of the relation between the phases of incisal path at border movement of the mandible and Krogh-Poulsen's muscular palpation. Accordingly, with the purpose of investigating these relationships, the author has made assessment of the relationship between the result by Krogh-Poulsen's muscular palpation and the form (analogue form) of three-dimensional incisal path at border movement of the mandible summarized and standardized by TMJ gnathological instrument which is evaluated as a recording method with high clinical efficiency as a method with excellent reproducibility of mandibular movement and favorable manipulability. The subjects enrolled were patients with temporomandibular arthrosis and the so-called normal healthy subjects with normally functioning occlusion who are not conscious clinically of the abnormality of the stomatognathic system nor had similar anamnesis. And the following results have been obtained. 1. Results by Krogh-Poulsen's muscular palpation; 1) The 59 so-called normal healthy subjects were classified into 2 groups by Krogh-Poulsen's muscular palpation, and of these, the cases in whom no abnormality was observed were only 5, being 8.5%, and the cases in whom single or multiple test items showed abnormality were 54, being so high rate as 91.5%. The occurring frequency of 5 test symptoms in the 54 cases were; 22 cases with trismus-40.7%; 34 cases with temporomandibular sounds -63.0%; 20 cases with pain -37.0%; 36 cases with tenderness of the lateral pterygoid muscle -66.7%; and 25 cases with disturbance of lateral mandibular movement -46.3%.(ABSTRACT TRUNCATED AT 400 WORDS)

[Clinical study on the relationship between chewing movements and temporomandibular joint abnormalities].

Chewing movements are accomplished by the harmonious function of the stomatognathic system. Therefore, TMJs play important roles in chewing movements. Recently, significant findings on TMJ abnormalities have been obtained from many studies. However, the relationship between chewing movements and TMJ abnormalities remains unclear. The purpose of this study was to examine how TMJ abnormalities were reflected in chewing movements. Incisor point movements during chewing (chewing pattern) were investigated in 150 abnormal and 25 normal subjects using Sirognathograph Analysing System. Abnormal subjects were composed of 45 patients with anterior disk displacement with reduction (reciprocal click), 20 patients with anterior disk displacement without reduction (closed lock), 50 patients with osteoarthrosis and 35 patients with MPD syndrome. Analysis of condylar movements during chewing were also performed in 9 normal and 20 abnormal subjects. The results were as follow; 1. Subjects with TMJ abnormalities tended to show abnormal chewing patterns when chewing at their non-abnormal sides. 2. TMJ abnormality of each different type tended to show its respective characteristic chewing pattern. 1) Subjects with osteoarthrosis and reciprocal click without condylar posterior dislocation tended to show deviation of the turning point to the non-chewing side, with a convex opening path in the frontal plane and a lack of anteroposterior width in the sagittal plane. This finding was associated with the limitation in movement of the abnormal-side condyle. 2) Subjects with reciprocal click with condylar posterior dislocation tended to show a concave opening path and reversed or cross-over patterns in the frontal and horizontal planes, respectively. This finding was associated with the movement of the abnormal-side condyle in the medio-anterior direction during the initial phase of opening. 3) Subjects with closed lock without condylar posterior dislocation tended to show deviation of the turning point to the non-chewing side, with a concave opening path in the frontal plane and a lack of anteroposterior width in the sagittal plane. This finding was associated with the severe limitation in movement of the abnormal-side condyle. 4) Subjects with closed lock with condylar posterior dislocation characteristically tended to show reversed or cross-over patterns in the horizontal plane. This finding was associated with the movement of the abnormal-side condyle in the medio-anterior direction during the initial phase of opening. However, this movement was smaller than that of the reciprocal click. 3. Subjects with MPD syndrome showed chewing patterns similar to those of normal subjects. From the results, close relationships were found between chewing movements and TMJ abnormalities.

Treatment strategy for patients with ectodermal dysplasia: a case report.

Ectodermal dysplasia (ED) is a hereditary condition characterized by abnormal development of the skin, hair, nails, sweat glands, and the stomatognathic system. There are many different types of ectodermal dysplasia of which X-linked anhidrotic ectodermal dysplasia is the most common. Multiple genes have been discovered to cause ectodermal dysplasias. With any form of ED, children may display a range of symptoms and challenging rehabilitation. This clinical report presents the treatment plan for a young patient with ED and anodontia requiring prosthetic restoration.

[Biomechanical problems of the maxillodental system in children].

The biomechanical regularities of the function of anatomic blocks of the maxillodental system were studied using mathematical simulation and mathematical models. The biological concept of the structure and biomechanics of human masticatory system is presented. Methods of rapid diagnosis, based on the anthropometric characteristics of the face, and a mathematical model of the function of the maxillodental system intended for the orthodontic treatment of maxillodental abnormalities in children have been developed.

Bite force and temporomandibular disorder in juvenile chronic arthritis.

The aim of this study was to investigate the functional condition of the stomatognathic system in children suffering from juvenile chronic arthritis, with respect to bite force and temporomandibular disorder in relation to radiographic abnormalities of the mandibular condyle, occlusal factors and systemic disease parameters. Thirty-five children with juvenile chronic arthritis were compared to 89 healthy children with an Angle Class I occlusion and 62 children with an Angle Class II malocclusion. Subjective symptoms and clinical signs of temporomandibular disorder and radiographic mandibular condylar changes were more common in children with juvenile chronic arthritis than in the two comparison groups. Maximal molar and incisal bite forces and maximal molar bite force endurance times were also significantly reduced in children with juvenile chronic arthritis. It is concluded that the differences between the groups are caused mainly by the systemic inflammatory disease itself, but a functional influence of weakened masticatory muscles cannot be excluded.

Acute and chronic postural abnormalities as related to craniofacial pain and temporomandibular disorders.

This article has focused primarily on the etiology of CFP and TMD that begins extrinsic to the stomatognathic system and may represent the causative factors behind continued patient complaints after medical and dental intervention. A close professional relationship between the dentist and physical therapist is essential. The knowledgeable physical therapist, through direct interaction with the patient's bodymind, can assist with facilitating change, restoring function, and increasing awareness. New ways of efficiently posturing and moving cannot be learned readily until old bodymind patterns are recognized. From here, the exciting mutual journey of discovery begins and the process continues to unfold for the therapist and client alike.

Effect of occlusion status on the time required for initiation of recovery in response to external disturbances in the standing position.

BACKGROUND: To examine whether occlusion status contributes to improvement of postural balance. METHODS: Thirty healthy adolescents (15 males and 15 females; mean age, 20.3; standard deviation (SD) 1.6 years) with no equilibrium or stomatognathic function abnormalities were examined. Occlusion is a term meaning "jaw clenching." Occlusion status was evaluated by measuring masseter activity using the EMG system. Balancing ability was evaluated using the EquiTest system, which measures sway of the center of gravity produced by rapid movement of force plates as an external disturbance (three intensity levels). The time required for initiation of recovery after application of the disturbance was calculated by measuring displacement of the center of foot pressure. Data were compared according to occlusion status. FINDINGS: Little difference in latency was observed following a small disturbances; however, the greater the disturbance the shorter the latency with occlusion, while without occlusion, latency increased with increasing disturbance. A statistically significant interaction (P<0.001) between occlusion and external disturbance was also found. INTERPRETATION: This study suggested that occlusion contributes to maintenance of postural balance and improvement of stability when unexpected sway occurs in the standing position.

[The condition of the stomatognathic system in children with gluten-dependent coeliac disease].

Stomatological examination was carried out of 38 children with coeliac disease. The condition of teeth with regard to caries was better than in children without coeliac disease. Occlusal abnormalities were noted in one-third of patients, in one-third of children with mixed teeth the dental age was delayed in relation to calendar age. No periodontal and mucosal changes were observed. The state of oral hygiene was estimated as good.

Disease in the neolithic population of the Lengyel culture (4300-4000 B.C.) from the Kujawy region in north-central Poland.

In this paper the skeletal sample from Osłonki near Włocławek (Kujawy region) is analysed. It is dated back to 4300-4000 B.C. The material consists of skeletal remains of 92 individuals (being one of the largest samples from the neolithic period in Poland). Skeletons were examined for the presence of congenital malformation, traumatic and degenerative changes, diseases of the masticatory system, and cribra orbitalia. Some interesting results have been achieved by comparing the incidences of diseases regarding sex groups: pathological alterations were observed with greater frequency in male than female skeletons.

Condylar movements during mastication.

To investigate the relationship between mastication and TMJ abnormalities, the incisal point and condylar movements during mastication were analysed in two normal subjects and six patients with stomatognathic dysfunction. The patients with stomatognathic dysfunction were two patients with unilateral anterior disk displacement with reduction, two with unilateral anterior disk displacement without reduction, and two with unilateral osteoarthritis. The incisal point movement was recorded using Sirognathograph Analysing System, and condylar movement was recorded with a pantograph. The movement path of the non-working condyle was shorter than that of the working condyle when patients with unilateral TMJ abnormalities used their non-abnormal side to chew, which resulted in deviation of the turning point (the point where the mouth changes from opening to closing) to the non-chewing side. Also, the convexity of the opening path was influenced by the condylar mobility of the abnormal side TMJ. Posterior dislocation of the condyle of the abnormal side TMJ resulted in a crossover chewing pattern of incisal point movement in the frontal or horizontal planes.

Radiographic evaluation of cervical spine of subjects with temporomandibular joint internal disorder.

Although the etiopathophysiology of internal temporomandibular joint internal disorders (TMJ ID) is still unknown, it has been suggested that head and body posture could be related to its initial onset, development and perpetuation. The purpose of the present study was to observe the relationship between cervical spine X-ray abnormalities and TMJ ID. This investigation evaluated 30 subjects with internal TMJ disorder symptoms (test group) and 20 healthy subjects (control group). Subjects were submitted to clinical and radiographic evaluation. Clinical evaluation comprised anamnesis and stomatognathic system physical examination. Radiographic evaluation comprised analysis of lateral cervical spine X-rays by three physical therapists and tracing on the same images. The test group presented twice as much cervical spine hyperlordosis as the control group (20.7% versus 10.5%), but almost half of rectification prevalence (41.4 versus 79.0%, p = 0.03). After that, the test group was divided into three subgroups according to TMJ dysfunction severity, evaluated by Helkimo's index. These subgroups were not significantly different, but the subgroup with more severe TMD showed a tendency to cervical spine hyperlordosis prevalence. Results showed a tendency for subjects with more severe TMD to exhibit cervical spine hyperlordosis. Nevertheless, studies with a larger number of subjects suffering from severe TMD are encouraged in order to corroborate the present findings.
