The bite in the temporomandibular joint pain dysfunction syndrome.

After reviewing the anatomy of the temporomandibular joint, the soft tissue classification of this syndrome is divided into three groups: macrotrauma, microtrauma, and stress situation. In each group, the etiology, physical findings, pathophysiology, and treatment are discussed. Bite assessment is reviewed so that the otolaryngologists will have a fuller understanding of the role that occlusal status plays in this syndrome. Before contemplating surgery, this status should be assessed by a competent dental colleague.

[Prosthetic treatment of a patient with complicated functional inferior prognathism].

The authors present their own case of prosthetic treatment of a patient with functional inferior prognathism complicated by deviation and supraocclusion. Two-stages treatment has been applied with utilization of overlaid splint-dentures and isometric and active exercises. Esthetic crowns on which desired canine teeth conduction has been obtained and frame dentures introduced in the new conditions of occlusion have been performed as the final treatment. Proper function of mastication has been restored and improvement of the appearance has been obtained that has considerably improved the frame of mind of the patient.

Simple hinge and semiadjustable articulators in orthognathic surgery.

Model surgery, an integral part of the planning of orthognathic surgical cases, can in some cases be performed on a simple hinge articulator, while in other cases a face-bow and semiadjustable articulator is required. Careful geometric and mathematic analyses of both simple hinge (for example, the Galetti) and semiadjustable articulators (for example, a Hanau) will yield definite indications for their use. The purpose of this article is fourfold: to discuss the theoretic errors inherent in the use of the face-bow record, to derive error formulas that calculate the errors inherent in the use of all articulators, to determine the indications for the use of simple vs. adjustable articulators, and to describe the use of a semiadjustable articulator and intermediate splint in two-jaw surgery. The error formulas show that, although a simple hinge articulator can be used in many cases, its use should be restricted to mandibular surgery, anterior subapical surgery, and transverse maxillary surgery. However, to err on the side of overuse of a semiadjustable articulator will not create difficulties in any orthognathic surgery case.

The use of a new 3D splint and double CT scan procedure to obtain an accurate anatomic virtual augmented model of the skull.

Three-dimensional (3D) virtual planning of orthognathic surgery requires detailed visualization of the interocclusal relationship. The purpose of this study was to introduce the modification of the double computed tomography (CT) scan procedure using a newly designed 3D splint in order to obtain a detailed anatomic 3D virtual augmented model of the skull. A total of 10 dry adult human cadaver skulls were used to evaluate the accuracy of the automatic rigid registration method for fusion of both CT datasets (Maxilim, version 1.3.0). The overall mean registration error was 0.1355+/-0.0323 mm (range 0.0760-0.1782 mm). Analysis of variance showed a registration method error of 0.0564 mm (P < 0.001; 95% confidence interval = 0.0491-0.0622). The combination of the newly designed 3D splint with the double CT scan procedure allowed accurate registration and the set-up of an accurate anatomic 3D virtual augmented model of the skull with detailed dental surface.

Telescope retainers for removable partial dentures.

Telescope crowns used in removable partial dentures reduce the destructive horizontal and rotational occlusal forces by directing them more axially and less traumatically than other retainers. These properties are combined with excellent conditions for cross-arch and multiple abutment splinting. If one of the abutment teeth needs extracting, the denture can be repaired with acrylic resin simply by remaking the secondary crown into a pontic. The single copings can be easily cleaned due to the good accessibility around their gingival margins. They also protect the abutment teeth against caries and thermal irritation. Soldering of the primary copings or their connection with accessory bars is not necessary in rigidly constructed telescope crowns, because the secondary crowns incorporated in the superstructure provide sufficient rigidity. In addition, the splinted copings often cause inflammatory gingival hyperplasia because the solder joints are too close to the gingival margins, preventing proper hygiene maintenance. The taper configuration or vertical height of the coping, which determines the amount of load transferred to each abutment, can be planned to suit each tooth's condition and designated function in the restoration. In a fixed restoration, the load is always evenly distributed among all the abutment teeth regardless of their condition, because the crowns are permanently cemented to them. In the telescope denture, the amount of force can be individually regulated by modifying the form and leverage of the retainers, according to their position, bone support, and occlusal conditions.

Non-crown and bridge stabilization of severely mobile, periodontally involved teeth. A 25-year perspective.

It is the author's belief, after analyzing forces and stresses on the periodontium for more than 30 years, that stabilization of severely mobile teeth can retain teeth, if in health, almost indefinitely. Because these teeth are retained using restorative materials, recurrent caries is a problem that needs to be treated. Tooth loss resulting from caries can occur. In the author's 26 years of using extracoronal adhesive resins for splinting, the technology of adhesive bonding and restorative resins have been improved. Earlier shortcomings of the physical properties of these materials never dissuaded the author from recommending splinting. When the cases were presented to the patient and the referring dentist, the types of the current materials used to splint teeth were immaterial. Realizing that improvements in adhesives and resins would be developed, the near-hopeless teeth were retained. Because the elderly population is the fastest-growing segment of the population, caries control is more of a concern than it was 50 or more years ago. Because teeth are being retained longer in this cohort, and because caries has a greater potential to exist, supportive periodontal therapy and recalls and caries examination become more important.

Intraoral acrylic splints for maxillofacial fracture repair.

Maxillofacial fractures in dogs and cats occur secondary to vehicular trauma, falls, kicks, gunshots, and fights with other animals. Pathologic mandibular fracture may occur secondary to periodontal disease, neoplasia, and metabolic diseases. The primary objective for repair of maxillofacial fractures in small animals is return to normal function. Therefore, it is necessary to maintain occlusal alignment while providing adequate stability for bony union. Basic principles of maxillofacial fracture repair include anatomic reduction and restoration of occlusion, application of a stable fixation to neutralize negative forces on the fracture, gentle handling of soft tissues, avoidance of iatrogenic dental trauma, extraction of diseased teeth within the fracture line, and minimizing excessive soft tissue elevation. This review article will describe the application of intraoral acrylic splints for maxillofacial fracture repair.

The immediate palatal plate.

The immediate palatal plate is therapeutically beneficial for relief of temporomandibular joint pain, for reduction of occlusal trauma with and without selective grinding, for orthodontic tooth movement as a disarticulating device, and for relief of pericementitis subsequent to periodontal surgery. The immediate palatal plate is durable and well tolerated by patients and has established itself to be more than just an interim appliance.

Posterior unilateral condylar displacement: its diagnosis and treatment.

The treatment procedure for posterior unilateral condylar displacement has been described. An acrylic resin repositioning prosthesis may be used to decrease trismus. Occlusal adjustment permits lateral freedom for mandibular movement to the opposite side which provides a dual, or a therapeutic, centric occlusion as well as the existing dysfunctional centric relation. This permits the patient's physiologic adaptive mechanism to choose between the existing dysfunctional centric relation, which resulted in unilateral condylar retrusion and pain, or a therapeutic centric occlusion which is aimed at anterior unilateral condylar repositioning. Over long period of time, muscle reprogramming produces maximum intercuspation of teeth in the planned therapeutic centric occlusion rather than in the original dysfunctional position. No explanation has been established for this phenomenon. It is important, however, to provide a technique that permits physiologic adaptability over a period of time. It should be emphasized that this is not TMJ "remodeling" but a functional change in the position of the jaw. The treatment objectives of bilateral and unilateral posterior condylar displacement are similar, but the clinical techniques are completely different. In either instance, TMJ radiographs are necessary to establish the diagnosis and treatment, as well as to document the postoperative results.
