A graphic evaluation of the intermaxillary relationship before and after therapy with the Michigan splint.

The effect of the Michigan splint was evaluated graphically in a group of 19 patients. Gothic arch tracings were registered before and after a period of therapy of 4 months, and the two tracings were compared photographically. The position of the apex of the Gothic arch was displaced in most patients, while the shape of the arch was more regular in almost all patients. The validity of the use of the Michigan splint was confirmed.

[Opening of chronic coronary artery occlusions with a recanalization catheter].

Percutaneous transluminal angioplasty for recanalization was attempted for 44 chronic coronary arterial occlusions in 41 patients (two occluded vessels in three patients). In 11 instances the occlusion could be passed with a guide-wire. In the other 33 this was not possible. In 25 of them a 3, 4 or 5 F recanalization catheter, its end tapered to 2 or 3 F, was used. In this way re-opening was possible in 17 cases (68%). The catheter made it possible to splint or stiffen the guidewire to keep it straight, superselectively inject contrast medium, measure the pressure distal to the occlusion, and gradually bougie-like enlarge the resulting subtotal stenosis. A total of 28 of 44 coronary occlusions were re-opened (64%). All these patients were functionally improved. At subsequent angiography (a mean of 3.6 months later) 22 of 25 vessels had remained open, but ten had narrowed and three had become re-occluded.

A comparative study of the fit and retention of interocclusal splints constructed from heat-cured and autopolymerized polymethylmethacrylate.

Fifty-three subjects each had a single Michigan splint constructed of either heat-cured or autopolymerized polymethylmethacrylate. The choice of material was decided randomly. A blind assessment for fit and retention was used on a three-point scale. Fit and retention were apparently unaffected by the material used. Thirteen percent of splints were unsatisfactory for clinical use (poor fit or retention) and this was also independent of material. A small number of splints contained structural faults (voids, porosity, or cracks) that may shorten the clinical life of these restorations; 9 of 12 such faults occurred in the autopolymerized group. Previous research has shown that conventional heat-cured polymethyl-methacrylate has superior properties compared with autopolymerized resin. In the absence of differences in accuracy of fit or retention, a heat-cured material is therefore advised where splints are intended for long-term clinical use.

Myofascial pain in a young violin player: a case report.

This report reviews a young patient who had undergone orthodontic therapy leaving occlusal interferences which were initially able to be tolerated. When symptoms of dysfunction arose, the general practitioner referred her to a specialist. The treatment involved a segmental bite-plane. Symptoms returned when the patient was under stress, and a Michigan splint was made as the segmental type of bite-plane is unsuitable for long-term use.

Mechanical evaluation of splint therapy in treatment of the edentulous patient.

Many edentulous patients have temporomandibular joint (TMJ) dysfunction that affects the use of their complete dentures. During the diagnostic and treatment-planning phase an ordered series of procedures must be performed. An arbitrary axis mounting, needlepoint and pantographic tracings on stabilized record bases will aid the dentist in determining the functional state of the TMJ and associated muscles. If no pathosis is found, a conventional denture technique can be used. If TMJ dysfunction is noted on the basis of an analysis of the tracings, an interim mandibular denture can be modified to correct the TMJ and musculature before new complete dentures are made. The occlusal scheme chosen for each patient can be based on a careful analysis of the tracings over a period of months.

Experimental occlusal interferences. Part IV. Mandibular rotations induced by a pliable interference.

In 12 subjects, a pliable, yet unbreakable, intercuspal interference (aluminum shim onlay splint; uniform height of 0.25 mm) was placed between either the right or left maxillary and mandibular second premolars and first molars. During brief and forceful biting (dynamic chewing stroke of about 20 kg force) the interference emulated a semisoft food bolus, and at the end of biting (subsequent static clenching stroke of about 20 kg force) it emulated a rigid metal interference. During dynamic/static biting, rotational electrognathography measured maximum frontal and horizontal plane torque of the right and left mandibular condyles. Eleven subjects (92%) showed frontal plane upward rotation (mean of 1.0 degree) of the condyle contralateral to the interference, and one subject (8%) showed frontal plane upward rotation (0.4 degree) of the condyle ipsilateral to the interference. Two subjects (17%) showed no horizontal plane rotation; seven subjects (58%) showed backward rotation (mean of 0.4 degree) of the condyle contralateral to the interference; and three subjects (25%) showed backward rotation (mean of 0.3 degree) of the condyle ipsilateral to the interference. It is suggested that, in the presence of an occlusal interference, mastication may have both short- and long-term detrimental effects.

Temporalis and masseter muscle activity in patients with anterior open bite and craniomandibular disorders.

Activity in temporalis and masseter muscles, and traits of facial morphology and occlusal stability were studied in 22 patients (19 women, 3 men; 15-45 yr of age) with anterior open bite and symptoms and signs of craniomandibular disorders. Facial morphology was assessed by profile radiographs, occlusal stability by tooth contacts, and craniomandibular function by clinical and radiological examination. Electromyographic activity was recorded by surface electrodes after primary treatment with a reflex-releasing, stabilizing splint. Maximal voluntary contraction was reduced compared to reference values, particularly in subjects with muscular affection, but maximal activity increased significantly when biting on the splint. Maximal voluntary contraction was positively correlated to molar contact and negatively to anterior face height, mandibular inclination, vertical jaw relation and gonial angle. Relative loading of the muscles was markedly increased during resting posture. It was concluded that reduced occlusal stability and long-face morphology were associated with weak elevator muscle activity with disposition overload and tenderness. The results also indicated that increase of occlusal stability might lead to increased muscle strength and possibly reduce risk of physical strain.

Effects of overdenture retention designs and implant orientations on load transfer characteristics.

Various approaches have been used for the retention and stabilization of implant-supported overdentures. This study examined photoelastically the simulated load transfer characteristics of a resilient cap attachment with moderately atrophied mandibular plastic models with two implant orientations. Comparison was made with overdentures supported by a splinting bar and a bar with distal resilient cap attachments. Stress patterns developed by simulated occlusal loading demonstrated little cross-arch load sharing and more uniform stress distribution with noninclined implants for all retention designs. The most equitable simulated occlusal force transfer was provided by the resilient cap attachments direct to the implants.

Early loading of sandblasted, acid-etched implants in the posterior maxilla and mandible: a 1-year follow-up report from a multicenter 3-year prospective study.

PURPOSE: The aim of the present study was to evaluate the concept of an immediate loading protocol in the posterior maxilla and mandible through analysis of implant survival at 1 year. MATERIALS AND METHODS: One year follow-up data of a multicenter study are reported. Eighty-two ITI sandblasted, acid-etched (SLA) implants in 40 patients were loaded between 0 and 11 days after implant placement (mean 4.3 +/- 2.8 days). The restorations consisted of either 2 splinted crowns or a 3-unit fixed prosthesis. All restorations were put into full functional occlusion. Periapical radiographs were evaluated for changes in crestal bone level from baseline to 1 year postloading. Primary stability of the implants was checked initially and before the fitting of the definitive prosthesis. The restorations were evaluated by the practitioners for retention, stability, and esthetics. RESULTS: Three patients' implants were not loaded because of lack of primary stability, and a fourth patient was excluded from the study because of a protocol violation (more than 4 implants were used). All 4 patients were successfully treated outside the protocol. The overall survival rate of the remaining implants at 1 year was 98.8%. The mean bone loss at 1 year was 0.52 +/- 0.98 mm, which is within the reported limits of less than 1 mm (range 0.4 to 1.4 mm) loss in the first year. DISCUSSION AND CONCLUSION: The early results from this study indicate that early and immediate loading of 2 implants in the posterior maxilla and mandible may be suitable in selected patients. On the basis of 1 year of observation, the results appear similar to those achieved with a delayed procedure.

The effects of conservative treatment on temporomandibular joint sounds and mandibular deviation during opening and closing movement of the mandible.

This study was undertaken to examine changes in temporomandibular joint (TMJ) sounds and mandibular deviations on opening and closing movements subsequent to conservative treatment of twelve patients presenting with mandibular dysfunction. A comparison of synchronous records indicated that two thirds of TMJ sounds were directly related to minor deviations in the path of movement of the mandible on opening and closing. TMJ sounds decreased significantly following flat plane splint therapy in all types, qualities and positions of sounds with the exception of those occurring near occlusal contact and those of a soft character. TMJ sounds related to minor mandibular deviations decreased significantly in all types, qualities and position of sounds except those of a soft nature. Fast Fourier Transform analysis of joint sounds consistently present before and after treatment revealed that the dominant frequencies were at the lower end of the acoustic range and that hard clicks have dominant frequencies higher than soft clicks.
