[Reproducibility of the jaw relation record].

The jaw relations in edentulous patients were determined with the use of the gotic arch and wax bite blocks. To compare the different methods interchangeable tracing devices and wax registrations were used. This apparatus was alternatingly used by various investigators, but with the same base plate. A quick and reliable survey of the results was possible with this experimental procedure. Our study confirmed the superior reproducibility of the graphic method with centrally supported needle.

[Radiocinematic comparison of the movement of the temporomandibular joint in the same patient with total prosthesis after various jaw relation recordings].

Six edentulous patients were each provided with two complete dentures and the relation of the jaws to each other was determined by means of both the conventional checkbite and a combined Gerber arrow-angle registration. Cineradiographic evaluation of the temporomanidibular joint movements did not confirm a bony or ligamental guidance, but showed that the condyle path is characterized by neuromuscular coordination. In four patients there was no characteristic difference in the form of condyle path when using the two dentures. But the condyle paths differed strikingly in those patients who had temporo-mandibular complaints or neuromuscular disharmonies. The paths were clearly steeper with Gerber dentures than dentures made after the conventional check-bite. In laterotrusion the "active" condyle moves on a straight line towards the from and downward, while the relatively "resting" condyle describes a shortened path corresponding to the initial part of an opening movement.

Stabilized record bases for complete dentures.

A step-by-step technique has been described to construct stabilized record bases which allows the dentist to take advantage of undercuts through the use of a resilient denture liner material in the undercut regions. The resilient denture liner material protects the rugae and prevents damage to the casts in the undercut regions during repeated placing and removal from the cast. Shellac denture base material at the posterior limit of the record base permits an easy method of checking the posterior palatal seal. The incorporation of the posterior palatal seal in the record base allows for adequate retention during the recording of the maxillomandibular jaw relation records and try-in procedures. The record bases made by the sprinkle-on technique are preferred to those made using the dough method. The bases are rigid, stable, not easily broken or warped, and fit accurately.

Occlusally oriented impressions for large maxillary stomas.

A stable record base is critical to the making of an accurate centric jaw relation record. This is attained by meeting three criteria: (1) a well adapted, adequately extended record base, (2) adequate support of the alveolar bone to prevent excessive movement of the record bases, and (3) accurate tissue integrity to allow good base adaption, maximum tissue contact, and minimum movement. If these criteria cannot be met--and they cannot in the bilateral subtotal maxillectomy patient--then an alternative method must be used. The combination jaw relation record-impression technique using the patient's pre-existing occlusion is an alternate method for the fabrication of a stable prosthesis. This method has been tested in several maxillofacial prosthodontic centers and has proved to constitute a realistic approach to the management of the subtotal maxillectomy patient.

Physical problems in obtaining records of the maxillofacial patient.

The maxillofacial prosthodontist has the dilemma of obtaining jaw relation records with structures that have been altered anatomically and/or physiologically. In the maxillae, problems associated with stability of the recording base require the prosthodontist to equalize pressure as best he can in obtaining jaw records. The maxillofacial prosthodontist is faced with the additional problem of altered mandibular movements. Five patients with lateral resections of the mandible were tested in a pilot study. These patients could not make protrusive or repeatable lateral movements. Anatomic correlations, especially the unilateral action of the mylohyoid muscle, may account for this pattern of abnormal mandibular movements. This study will continue.

A denture tray technique for remake dentures.

A technique is described to fabricate a replacement denture for your patient. It reduces patient and laboratory time. The technique does not compromise the patient's existing denture, the impression, jaw relation records, or esthetics. It provides superior trays and effective occlusion rims, thus simplifying recording techniques. A denture duplicating flask may be substituted for the two plastic impression trays to duplicate the denture. The duplicating flask may improve realignment of the upper and lower molds, but additional irreversible hydrocolloid is required to fill the mold.

The trial denture.

1. Many difficult situations can be avoided if the dentist keeps constantly aware of the physiologic, the psychologic, and the artistic factors involved in the construction of dentures, whether they be partial or complete. 2. No one would think of buying an automobile without getting adequate instruction in how to drive; neither should a patient expect to wear artifical restorations without training and practice. 3. The dentist at the try-in should check: a. The bases for fit and extension. b. Thin labial flange at frenum area. c. Posterior palatal seal and length of upper. d. Posterior tooth poisition for height of plane, relation of plane to alatragus line, tongue room, and ridge relation. e. Anterior tooth position for lip support, length, and relation to lower lip. f. Entire setup for vertical dimension of the face, test balance and simultaneous tooth contacts in all desired positions. If discrepancies exist between the articulator and the mouth, make new jaw relation records. g. Check palatal contour and incisor positions in speaking. "F" and "V" sounds to test the upper incisor, sibilant sounds for vertical dimension and lower-to-upper incisal relationships. h. Wax-up for support and proper external form. If tori exist on upper or lower, be sure there is sufficient thickness to allow relief later on. i. Be sure to repeat and continue instruction of the patient in his understanding and handling of the new dentures. Now, in addition to all these checks to dentist makes, he must constantly anticipate the thoughts and attitudes of the patient and interpret them for better rapport and ultimate patient understanding. No stage in complete dentures is anticipated with such mixed emotions as is the try-in. No stage is so significant to the future success or failure of the patient to take dentures in his stride. No stage has so much potential for making the person happy or sinking him into the depths of despair. The return of self-confidence, the pride in appearance, the sparkle and drive that return to a patient when the restorations are enthusiastically accepted are a wonderful reward for dentistry well done.

[Myoarthropathies: findings and therapy].

Im myoarthropathies the interplay of the functions of articulation, mandibular joints, muscles and periodontium is disturbed. They are due to occlusal disorders. The oral examination is carried out according to Krogh-Poulsen. The therapeutic procedure involves three steps. Step 1 : elimination of gross occlusal disorders. Step 2: elimination of occlusal disorders after recording of the jaw relations and model analysis on the articulator. Step 3: prosthetic treatment.

Basic method for recording occlusal traits.

This article describes a basic method for the recording of malocclusion that has been developed jointly by the World Health Organization and the International Dental Federation. The method was developed and field-tested in the period 1969-78 and should provide investigators and health authorities with a common basis for assessing the prevalence of malocclusion in various parts of the world. It should also serve as a basic reference tool in the development of methods for assessing the need and demand for orthodontic treatment.
