Tooth splinting: a review of the literature and consideration of the versatility of a wire-composite splint.

The principles of tooth luxation splinting have been changed since the animal and human tests conducted in the early 1970s showed that masticatory stimulus promotes healing of luxated teeth and normally exerted occlusal forces are able to prevent and eliminate small resorption cavities on the root surface. It has also been shown that fixation of only one week is enough to achieve the clinical healing of repositioned teeth. Apart from esthetic and hygienic components, present-day demands on tooth fixation techniques also include ease of construction and removal and the use of devices which allow slight movement of the fixed teeth. This paper presents the history of tooth splinting, our present-day knowledge of the subject, and introduces various splinting techniques. The wide range of indications for a flexible wire-composite splint are analyzed more thoroughly.

Traumatic intrusion of permanent teeth. Part 3. A clinical study of the effect of treatment variables such as treatment delay, method of repositioning, type of splint, length of splinting and antibiotics on 140 teeth.

A prospective study of 140 intruded permanent teeth was examined for the following healing complications: pulp necrosis (PN), root resorption (RR; surface, inflammatory and replacement resorption), and defects in marginal periodontal bone healing (MA). The occurrence of these healing complications was related to various treatment factors such as treatment delay, method of repositioning (i.e. expecting re-eruption, orthodontic reposition and surgical reposition), type of splint (rigid, semirigid and flexible), length of splinting (days) and the use of antibiotics. Treatment delay, i.e. before and after 24 h, had no effect upon healing. Active repositioning in individuals with incomplete root formation (surgical or orthodontic) had a negative effect upon the three healing parameters compared with spontaneous eruption. In teeth with complete root formation and an age of 12-17 no repositioning was still the best treatment in regard to MA. In individuals older than 17 years of age, cases were not anticipated to spontaneously erupt and in these cases, the general choice of treatment was either active orthodontic or surgical repositioning. The former procedure appeared in this treatment scenario to slightly reduce the risk of MA complications. However, this treatment procedure was also found to be more time demanding (an average of 22 consultations for orthodontic repositioning compared with 17 consultations for surgical repositioning). If a surgical repositioning was performed, the type of splint (i.e. flexible, semirigid or rigid) appeared to have no significant effect on the type of healing. The same applied to the length of splinting time (shorter or longer than 6 weeks). No effect of dentin covering procedures for associated crown fractures (enamel-dentin fractures) could be demonstrated. Likewise, antibiotics had no apparent effect upon healing. In conclusion, in patients with intruded teeth with incomplete root formation, spontaneous eruption should be expected. In patients with completed root formation and with an age of 12-17 spontaneous eruption can still occur, but must be monitored very carefully. In older patients (i.e. >17 years) with completed root formation, either surgical or orthodontic extrusion should be attempted. The latter procedure appeared to lead to a slight reduction (not significant) in the risk of MA complications. The extent and direction of the intrusion may however favour surgical repositioning.

Splinting in rheumatoid arthritis: II. Evaluation of Lightcast fiberglass polymer splints.

Fifty-four patients with rheumatoid arthritis were fitted with fiberglass polymer Lightcast II hand and wrist splints. When patients were questioned after having worn the splints for 9 to 12 months, the majority responded that the splints were durable, cosmetically acceptable, and for the most part comfortable. The splints were staff manufactured at 1 sitting in less than an hour each.

A comparison between horizontal splint and repositioning splint in the treatment of 'disc dislocation with reduction'. Literature meta-analysis.

We reviewed the literature from 1985 to 1996 concerning the preliminary treatment of disc dislocation with reduction (DDWR) by means of occlusal splints, pinpointing two main methods. The conflicting results of many papers induced us to make a literature meta-analysis of those articles with the necessary requirements in order to verify the effectiveness of the two therapeutic means more frequently used in DDWR; the repositioning splint and the bite plane. A statistical comparison between the two kinds of treatment has demonstrated that the repositioning splint is more effective both in the resolution of the articular click and of the pain at a level of P < or = 0.00001, which is noteworthy and highly significant.

The Mexican hat splint--a new splint for the treatment of closed mallet finger.

A new splint for the treatment of closed mallet finger injuries is described. This is a modified aluminium-foam ('Zimmer') splint, which takes account of the skin circulation at the distal interphalangeal joint, and is specifically designed to alleviate the potential problems which can be seen with the traditional 'mallet finger' splints.

A splint for pincer nail surgery: a convenient splinting device made of an aspiration tube.

BACKGROUND: To treat pincer nail, both conservative therapy and surgical therapy have been reported. However, there is no consensus about the best method of treatment. OBJECTIVE: The use of a splint prepared from an aspiration tube after pincer nail surgery is introduced. METHODS: Pincer nail was treated by surgery with splinting in seven patients (nine toes). RESULTS: Nine toes from seven patients were evaluated. The postoperative follow-up period ranged from 6 to 37 months (mean 17.7 months). An excellent result was obtained in eight toes, but ingrowth of the nail occurred in one toe. The cosmetic improvement was marked and satisfactory. CONCLUSION: This splint is cheap and easy to make, can prevent contracture of the nail matrix and nail bed, can reduce pain, and allows direct observation of the nail bed because it is transparent. Thus, this technique seems to be convenient and useful.

Soft splinting with neoprene: the thumb abduction supinator splint.

Thermoplastics are useful for many types of splints, but most splints made from them position the hand statically and have the disadvantage of limiting the sensory feedback that occurs during normal use and movement. Neoprene is an alternative to thermoplastics when dynamic mobility in splinting is the goal. Neoprene is soft, stretchable, lightweight, durable, nontoxic, machine-washable, and has a good memory. The TASS uses the Bobaths' key point of forearm supination and thumb abduction to position the upper extremity more functionally without the patient having to use effort. Thus sensory feedback can occur while the limb is moving within a prescribed range. The TASS can be used as an extra "hand" during the occupational therapy treatment session, or it can be applied immediately after treatment to continue to facilitate functional positioning of the limb.

Accuracy of implant impression splinted techniques: effect of splinting material.

Three implant impression techniques, using 3 different splinting materials, were assessed for accuracy in a laboratory model that simulated clinical practice. For group A, an autopolymerizing acrylic resin was used to splint transfer copings. In group B, a dual-cure acrylic resin was used, and for group C, plaster, which was also the impression material, was used. A metal implant master cast with an implant master framework was made to accurately fit to the cast. This cast was the standard for all impressions. For each group, 15 impressions were made. Polyether impression material was used for groups A and B. The accuracy of the stone casts with the implant analogues was measured against the master framework, using strain gauges. A multiple analysis of variance with repeated measures was performed to test for significant differences among the 3 groups. Additional analyses of variance were carried out to locate the source of difference. The statistical analyses revealed that a significant difference existed between groups A and B and between groups B and C but not between groups A and C. Impression techniques using autopolymerizing acrylic resin or impression plaster as a splinting material were significantly more accurate than dual-cure acrylic resin. Plaster is the material of choice in completely edentulous patients, since it is much easier to manipulate, less time consuming, and less expensive.

Neutral wrist splinting in carpal tunnel syndrome: a 3- and 6-months clinical and neurophysiologic follow-up evaluation of night-only splint therapy.

AIM: The aim of the study was to evaluate the long-term efficacy of night-only splint wear therapy for carpal tunnel syndrome (CTS). METHODS: We conducted a randomized case-control trial with evaluation after three and six months of follow-up of outpatients with mild, recent onset symptoms of CTS recruited from the department clinic. Fifty patients (50 hands) were enrolled, of which 36 completed the study at 6 months. The case group utilized a thermoplastic neutral wrist splint for night-only wear. Outcome measures were instrumental parameters (sensory and motor nerve conduction velocity), symptom and function alterations (as measured by Levine's self-administered questionnaire), clinical parameters (pressure-provocative and Phalen tests). RESULTS: Improvements were observed in Levine's symptom status score at the three-month (P=0.001) and the six-month (P=0.001) follow-up visits, in functional score (P=0.0001) and (P=0.0004), in median distal sensory latency (P=0.01) and (P=0.02), in pressure-provocative test outcome (P=0.01) and (P=0.003), in Phalen test outcome (P=0.04) and (P=0.05) respectively. CONCLUSION: Symptom relief and neurophysiological improvement after night-only splint wear therapy lasted up to the six-month follow-up visit.

[A comparative study of the "Levame" type extension splint and the "Low Profile" type extension splint: impact on therapeutic indications].

The most widely used dynamic extension systems, both to straighten the digital flexion retractions as well as to ensure directed mobilization after surgical repair of extensor tendons, are the so-called "Levame" and "Low Profile" splints. This study analysed the application of forces for these two types of extension splints, the directional constraints which they impose and freedom of joint movement which they allow in order to more clearly define the type of motorization to be used as a function of the most frequent indications.

An investigation on the use of cryosurgery for treatment of bone spavin, splint, and fractured splint bone injuries in standardbred horses.

Bone spavin, splint, and fractured splint bone injuries have been treated with varying methodologies at Wheatley Hall Farm Equine Clinic. Cryosurgery is the most successful. With cryosurgery the small, pain-producing afferent C fibers are destroyed, and painful neuromas do not return. Injured sites were cryosurgically treated with liquid nitrogen for a double freeze-thaw period of 45 sec. 5 sec, 45 sec. Before and after treatment comparisons were conducted on study standardbreds. In all three injury groups, results showed that the standardbreds tended to race as well or with improved times and classes after treatment. With cryosurgery, the horse undergoes a relatively short layoff period and does not experience any of the problems associated with other surgical procedures. Unlike denerving, a horse is still aware of outside stimulus to the treated area. Based upon personal observation and this preliminary investigation, cryosurgery provides a successful treatment alternative which is safe and humane to the horse, requiring a very short layoff or recovery time.

Endothelial damage in microvascular anastomosis: to splint or not to splint?

When performing a microvascular anastomosis, some surgeons use a splint and others do not. We compared the difference in intravascular reactions observed in the carotid artery of the rat anastomosed with these two techniques by observation with a scanning electron microscope. Thrombus formation was more prominent in the artery anastomosed using a splint. The difference was most remarkable 20 minutes after anastomosis. With time, the difference became less remarkable and was no longer present by seven days. By fourteen days, the anastomotic site was covered with neoendothelium. It is concluded that there is little difference in the final outcome achieved by the two methods.
