Effect of hand splints on stereotypic hand behavior of girls with Rett syndrome: a replication study.

The purposes of this study were to replicate a recent report of the positive effects of hand splinting on the stereotypic hand movement of children with Rett syndrome and to evaluate the generality of these results to a different setting. Two 5-year-old girls diagnosed with early Stage-III Rett syndrome were introduced to hand splints in accordance with the multiple-baseline design used in the Naganuma and Billingsley study. Splint wear ranged from 30 to 50 days for the two subjects. Data were analyzed as a percentage of time and as actual time in minutes. Unlike the previous study, in which a decrease in hand-wringing behavior was noted, neither subject in our study demonstrated a decrease in stereotypic hand behavior or a subsequent increase in independent feeding skills when wearing the splints. There was also no evidence of increased hand wringing following withdrawal of the splints. The differences in ages of the subjects and different functional levels (stages) may have been contributing factors to the conflicting results and should be considered in managing this group of children.

Have you tried the sandwich splint? A method of preventing hand deformities in children.

The prevention of contractures of the burned hand is an arduous problem in the young pediatric burn patient. Difficulty in applying splints, along with the time-consuming fabrication of complex splints, led to the development of the "sandwich" splint. This easily produced splint provides a means of preventing and treating hand deformities in this patient age group. Positive results have been noted with the use of this splint in conjunction with the patient's usual active physical therapy program.

Analysis of materials for splinting of the thermally injured patient.

Good results have been achieved in the treatment of patients with burns with new splinting materials and proper splinting techniques. This article focuses on the thermoplastic splinting materials Clinic and Spectrum (Northcoast Medical Inc., San Jose, Calif.) and the comparable thermoplastic products Polyform (Smith & Nephew Rolyan, Inc., Menomonee Falls, Wis.) and Orthoplast (Johnson & Johnson Orthopedics, New Brunswick, N.J.). Qualities such as self-bonding, recyclability, and rigidity were tested for these materials. Splint rigidity was measured by a calibrated hook scale and determined by the force per pound needed to bend the material 20 degrees. Spectrum and Clinic products were judged more economical and, we contend, they are therefore better choices for splinting the thermally injured patient.

Influence of an occlusal splint on integrated electromyography of the masseter muscles.

In order to examine the effect of an occlusal splint on the integrated electromyography (EMG) of the masticatory muscles, EMG of bilateral masseter muscles of 23 patients with temporomandibular joint disturbance syndrome (TMJDS), with and without an occlusal splint, was measured and integrated on line during maximum clenching. It was found that the integrated myoelectrical value of the masseter muscle on the involved and non-involved side was reduced with the occlusal splint. The absolute difference between integrated myoelectrical values in the left and right masseter muscles was reduced with an occlusal splint, but the relative difference remained virtually unchanged. These results indicate that the occlusal splint can decrease masseter muscle activity and thus exert a therapeutic effect.

Influence of splints and temporary crowns upon electric and thermal pulp-testing procedures.

The influence of different splints and temporary crowns upon the reliability of electric and thermal pulp-testing procedures was examined in 10 patients with vital maxillary central incisors and 10 patients with vital maxillary central incisors and 10 patients with unilateral pulp necrosis of a central incisor. The pulp-testing procedures were: (1) Bofors Pulp Tester, (2) Siemens Sirotest, (3) heated guttapercha, (4) ice, and (5) carbon dioxide snow (Odontotest). The splints or temporary crowns were: (1) silver cap splint, (2) acrylic cap splint, (3) Hawley orthodontic plate, (4) Saur's arch bar, (5) orthodontic bands, (6) stainless steel crown, and (7) stainless steel crown with labial surface removed. A reliable electrometric pulp response could only be elicited if the pulp tester was applied directly upon enamel and preferably upon the incisal edge. In this instance metal splints or partial steel crowns applied to the tooth had no effect on the pain threshold. A false positive reaction in case of pulp necrosis was only elicited when the electrode was placed directly upon metal which contacted neighboring vital teeth. The use of ice and heated guttapercha appeared to be of limited value, due to inconsistent pulp responses. Carbon dioxide snow gave a reliable response, unless applied on the incisal edge.

Effect of splint placement on black-pigmented Bacteroides and spirochetes in the dental plaque of beagle dogs.

The gingival microbiota in beagle dogs was investigated during a period of 42 days after the placement of continuous wire and arch bar splints. The splints were found to induce an increase in helicoidal-shaped micro-organisms and black-pigmented Bacteroides. Two different asaccharolytic Bacteroides types were isolated and tentatively identified as B. gingivalis and B. asaccharolyticus. In addition, B. intermedius-like organisms were isolated. The last two species were observed only after splint placement. The local accumulation of helicoidal-shaped micro-organisms in the epithelial tissue rather than in the micro-ulcerations was regarded as an indication of an active role for these spirochetes in the disease process. The observed shift toward tissue-invading and potentially pathogenic micro-organisms after splinting stresses the need for antimicrobial measures during splint placement in order to minimize periodontal destruction.

The Sheffield splint for controlled early mobilisation after rupture of the calcaneal tendon. A prospective, randomised comparison with plaster treatment.

Forty patients with acute complete rupture of the calcaneal tendon were managed conservatively and randomly allocated to treatment groups using either cast immobilisation for eight weeks, or cast immobilisation for three weeks, followed by controlled early mobilisation in a Sheffield splint. The splint is an ankle-foot orthosis which holds the ankle in 15 degrees of plantar flexion, but allows some movement at the metatarsophalangeal joints. It is removed to allow controlled movement during physiotherapy. Patients treated with the splint regained mobility significantly more quickly (p less than 0.001) and preferred the splint to the plaster cast. The range of dorsiflexion at the ankle improved more rapidly after treatment in the splint (p less than 0.001), and patients were able to return to normal activities sooner. Recovery of the power of plantar flexion was similar in the two treatment groups, and no patient had excessive lengthening of the tendon. One re-rupture occurred in each group.

Evaluation of occlusal splint therapy and relaxation procedures in patients with temporomandibular disorders.

Twenty-four patients were selected to participate in this study. Twelve patients were randomly selected to receive occlusal splint therapy and the other 12 to receive a simplified relaxation therapy technique. Observable pain scores, maximum comfortable interincisal distance, and maximum interincisal distances were recorded for each group before and after treatment. The occlusal splint group showed a significant decrease in total mean observable pain scores (decrease score of 10.5, t = 3.124; P less than 0.1). The relaxation group showed no significant decrease in total mean observable pain scores (decrease score of 1.8, t = 0.888; P = ns). The occlusal splint group showed a significant increase in the mean maximum comfortable opening (an increase of 12.4 mm, t = 5.085; P less than .01). The relaxation group showed no significant increase in the mean maximum comfortable opening (an increase of 2.3 mm, t = 0.734; P = ns). The occlusal splint group showed a significant increase in the mean maximum opening (an increase of 6.0 mm, t = 2.471; P less than .05). The relaxation group showed no increase in the mean maximum opening (decrease of 0.7 mm, t = 0.343; P = ns). This study suggests that occlusal splint therapy is a more effective treatment for the pain, tenderness, and limited mandibular opening associated with temporomandibular disorders than relaxation therapy. In this study, the relaxation technique used had no significant effect on the patients' pain, tenderness, or limited opening.

The effects of hard and soft occlusal splints on nocturnal bruxism.

Occlusal splints are commonly used for the treatment of nocturnal bruxism. This study investigated the effects of hard and soft occlusal splints on nighttime muscle activity. The nocturnal muscle activity of ten participants was recorded while wearing a hard and then a soft occlusal splint. The hard occlusal splint significantly reduced muscle activity in eight of the ten participants. The soft occlusal splint significantly reduced muscle activity in only one participant while causing a statistically significant increase in muscle activity in five of the ten participants.

Mandibular alveolar ridge extension method using a surgical splint with porous hydroxyapatite (HAP) particles.

The mandibular alveolar ridge extension method is a surgical technique to extend the alveolar ridge up to the required level. Using a surgical splint prepared to meet the clinical requirements establishes the desirable alveolar ridge extension with porous hydroxyapatite (HAP) particles. Before the operation, a working cast of the extremely resorpted mandibular alveolar ridge is remodeled into its desired shape with paraffin wax, and the extended surgical splint is cured by clear acrylic resin. After subperiosteal tunnel dissection, the surgical splint is fixed to the mandible with circummandibular ligatures; then the HAP particles are injected into the tunnel. After healing, a treatment denture is cured between the artificial dentition and the surgical splint with self curing resin. In this method, the HAP particles are injected into the subperiosteal tunnel that is created between the surface of alveolar bone and the periosteum covered by the surgical splint; the migration of HAP particles completes the extension of the alveoral ridge.

Effects of lateral rotation splinting on lower extremity bone growth: an in vivo study in rabbits.

To study the effect of lateral splinting on limb development, 14 immature rabbit femurs and tibias were marked with six parallel pins. Of these, the lower limbs of seven rabbits were splinted in lateral rotation for 3 weeks (1-year human equivalent). The static position of the foot in the splinted group was 23 degrees more lateral (p greater than 0.05) than in the control group. No significant difference was found in the axial alignment of the pins across the growth plate or diaphyses between the splinted or control groups. This study suggests that night splinting alters the joint relationships and not the shape of the femur or tibia.

Carpal tunnel syndrome: objective measures and splint use.

One hundred five adults with carpal tunnel syndrome (CTS) were studied to assess the efficacy of a neutral-angle wrist splint, and to identify criteria for splint referral. Ten observations before and after treatment were analyzed with descriptive and inferential statistics. After splint use, 67% of the subjects reported symptom relief. T-test comparison of sensory latency of values before and after treatment indicated improvement for the total group. Chi-square and t-tests failed to reveal significant differences between relief and no-relief groups for gender, affected hand, presence of concomitant conditions, duration of symptoms before treatment, age, length of time between pretreatment and posttreatment nerve conduction testing, initial nerve latency of motor and sensory fibers, or the difference between pretreatment and posttreatment sensory latencies. A significant difference was found for motor latency; the relief group improved and the no-relief group deteriorated. Data suggest that splinting is most effective if applied within three months of symptom onset. Those with damage to the wrist structures or median nerve were least responsive to splinting.

[Long-term splinting of a traumatic upper permanent incisor with root fracture: report of a case].

Splinting was administered in a case of a traumatic upper right permanent incisor with root fracture. The patient was a boy, 11 years and 10 months old. The radiographical examination indicated that the injured tooth, that had already completed the apical growth, fractured horizontally at the middle 1/3 part of root. Clinical findings showed severe mobility of the coronal fragment of the injured tooth and a small amount of bleeding from the gingival sulcus, but there was almost no disposition of the coronal fragment and it was found to be vital in the electric pulp test. Immobilizing the coronal fragment of the injured tooth with the resin splint bonded directly to the tooth surfaces was prescribed. After 31 months, the pulp of the injured tooth remained vital, and after the elimination of the line of fracture and no symptoms of ankylosis were radiographically confirmed, the splint was then removed. From the case reported above the following implications were obtained: Although the previous investigators reported that the term of splinting teeth with root fractures was for 2-3 months, and prognosis of the injured teeth with root fractures having severe mobility of the coronal segments might be unfavorable, it was also indicated that the healing process by calcification might be possible with the use of long term splinting, as the pulp remained vital. In this case, it was found that the repair by calcification appeared initially on the proximate portion of the pulp at the fractured line, and slowly proceeded into the direction of the site of the outer surface of the root along the fractured line.

[Biomechanically optimized construction of occlusal splints and subjective evaluation by probands].

In a double blind study twelve class I probands received occlusal splints with six different customized anterior guidances. The subjective feelings were rated using a psychologic scale. It was shown, that splints with a large "a" were better rated than splints with a small "a". "a" is the radius of the maximal curvature of the sagittal anterior tooth curvature. The transition between positive and negative ratings was very sharp and localized at the individual "a". These results suggest that occlusal splints can be optimized by including customized anterior guidances. A detailed technical description of the manufacturing of these splints is given.

Postoperative splinting of the pediatric upper extremity.

The protective splint described above provides appropriate immobilization and protection for our postoperative pediatric population. The major advantages of this splint over plaster of paris include direct access to the wound, easy reapplication, and unnecessary use of the plaster-cast saw. In addition, thermoplastic splints are lightweight, less bulky, more durable, water-resistant, and easily remolded. The therapist's approach to the patient and parents is of utmost importance and will affect the outcome of the splint. In conclusion, postoperative pediatric splinting can be a challenging experience that requires a significant amount of patience, knowledge, and creativity on the part of the hand therapist.

[Application of occlusal splint for the patient with temporomandibular joint dysfunction. An application of silane coupling treatment: a case report].

The bite plane therapy has been one of the most useful treatment methods for patients with temporomandibular joint (TMJ) dysfunction. But the bite plane usually causes esthetic and articulation disturbances and it is occasionally difficult to use during mastication. The authors have fabricated a new type of bite plane, named occlusal splints, which covers each side of the premolars and molars. The occlusal splint was constructed by a hard-resin for the occlusal part and cast clasps for the retentive part and these parts were adhered after a pre-treatment of metal by the use of a silane coupling agent (Silicoater system). The patient was a 35 year-old man, with a chief complaint of left side reciprocal TMJ clicking. The anterior repositioning type of bite plane was applied for the treatment with the diagnosis of anterior disk displacement with reduction. But he complained of esthetic and articulation disturbances especially during working and eating. After four months we fabricated an occlusal splint that can be used for a long period of time. The patient was satisfied to use this occlusal splint and no symptoms of TMJ dysfunction were found with this appliance. It is suggested that the occlusal splint consisting of a hard-resin and cast clasps is a useful appliance especially for the purpose of use during working and eating, and for evaluating the properness of mandibular position.

[A new method of dental splinting].

A wire splint and the technique of its application for jaw immobilization is described. Stainless steel wires 0.7 to 1 mm in diameter are used to form the smooth and looplike parts applied to dentition in such a manner that loops be located closer to gingival margin and smooth part be situated in the vicinity of incisive margins of the teeth. Usually, the smooth part is an extension of looplike part of the splint and serves to embrace the lateral teeth into the splint. Both ends of the smooth part can be twisted together. The results of clinical application of the splint are compared to most common techniques and suggest major advantages of the novel splint.
