A computerized tomography (CT) scan appliance for optimal presurgical and preprosthetic planning of the implant patient.

This article describes the technique for using the CT (computerized axial tomography) scans, with specially designed software and an adjunct appliance, for accurate planning of dental implants and implant-supported restorations. The available bone can be evaluated, surgical problems anticipated, and errors in placement avoided. The learning objective of this article is an enhanced knowledge of the extended application of the CT scans and the use of the orientation and immobilization appliance.

Occlusion and restorative dentistry: Part II.

When planning treatment for major reconstruction of a dentition, occlusal factors which can affect the comfortable functioning of the masticatory system are a prime consideration. Anterior guidance and posterior support contribute significantly to the comfortable functioning of the masticatory system. Aesthetic factors are also significant for, in providing anterior guidance, the alignment, lengths, and proportions of incisors are as critical as their shape, colour and surface texture. Finally, treatment does not end with the insertion of the fixed and removable prostheses. Continual maintenance over the years can be as challenging as the reconstruction.

Characterization of 86 bruxing patients with long-term study of their management with occlusal devices and other forms of therapy.

Of 353 patients screened, 86 answered positively to questions designed to identify bruxers. The bruxing patient profile revealed that 100% had working excursive interferences, 78% had balancing excursive interferences, and 95.4% had a premature contact into maximum intercuspation. Most of the bruxing patients had a chief complaint that related to pain, and 89.6% of the patients had a craniomandibular disorder. The patients were initially managed with an anterior deprogrammer and were later managed with other occlusal devices as signs and symptoms dictated. Definitive treatment was determined by the patient's maxillomandibular relationship.

The role of bioelectronic instruments in the management of TMD.

Temporomandibular disorders (TMD) comprise a group of conditions that can affect the form and function of the temporomandibular joint (TMJ), masticatory muscles and dental apparatus. Proper management of TMD by the dentist requires accurate appraisal of the status of the patient's dentition, TMJ and associated neuromuscular apparatus. Certain predefined standards or parameters of function/dysfunction are accepted by the profession. Electronic instrumentation provides objective measurement of many of these biological phenomena, and thus can be used throughout treatment for critical analyses that monitor and enhance treatment efficacy. A treatment protocol for TMD is presented that uses electronic instrumentation to establish a neuromuscular occlusion.

Occlusion as a causative factor in TMD. Scientific basis to occlusal therapy.

There appears to be a pendulum swing toward large epidemiologic studies questioning the role of occlusion in dentistry. This article clearly demonstrates that significant scientific evidence exists on the side of occlusal causative factors. Clinicians need this current information to base practical decisions of treatment relative to both patients and those requiring restorative procedures. It further correctly clarifies that stress-related issues have an important role, along with other host-susceptibility altering factors.

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.

Obstructive sleep apnea: a mandibular positioning device for treatment and diagnosis of an obstruction site.

Obstructive sleep apnea (OSA) is a common condition with serious health and social consequences for millions of people. If untreated, it has significant effects on mortality, particularly by contributing to the rate of hypertension, stroke, and cardiac pathology. Standard therapy involves the use of a nasal continuous positive airway pressure device during sleep. This keeps the upper airway from collapsing, avoiding the cause of apneas and hypopneas. The inconvenience and side effects of the device make compliance with its use less than ideal. There are several surgical techniques that have been developed to correct OSA. These techniques have had variable success rates and are accompanied by some morbidity and mortality. Intraoral devices that position the mandible forward show promise for increasing the hypopharyngeal airway. A technique for physiologically determining an effective jaw relationship is described, as is a design for a device that maximizes nighttime retention. Radiographic analyses in the upright and supine positions are used to determine adequate airway improvement. The intraoral device can be used as a diagnostic tool to select patients who will most likely benefit from surgery.

Influence on isometric muscle contraction during shoulder abduction by changing occlusal situation.

Many studies have been performed on the mandibular orthopedic repositioning appliance (MORA) as an athletic performance enhancer since the late 1970s. The concept that changing the mandibular position would increase the strength and improve the performance of subjects has been a source of controversy among various researchers. The strength of shoulder abduction and electronic activities of six muscle groups in the upper body were tested on seven subjects in this study. The normalized data for four different situations: rest position, MVC (Maximum Voluntary Contraction) in an intercuspal position, MVC with placebo, and MVC with MORA in supported rest position were analysed. Statistical analysis demonstrated that the MVC with MORA was significantly stronger than the rest position for upper appendage strength. The electronic activities of all muscle groups were significantly greater with MORA than those in rest position, and some of them were significantly greater with MORA than with either MVC or placebo situation. THe results suggested that the muscle activities of the upper appendage were increased by biting MORA in the supported rest position during the shoulder abduction performance.

[Otologic signs, craniofacial pain and dental malocclusion].

An occlusal problem can explain otologic symptoms and myofacial pains. A dental and an occlusal examination is necessary to find the true mechanism. If the occlusal examination is not immediately possible, the scheme of the biting retro incisive helps to the diagnosis, in motter to put in place a treatment. In this complete study with a backward regard of 79 patients, 62 have been treated with a total success.
