Tooth stabilization and splinting before and after periodontal therapy with fixed partial dentures.

The design and use of fixed partial dentures as a definitive restoration to stabilize and splint teeth have been reviewed. The provisionalization of the splinted patient has been described as it is incorporated into the treatment plan of patients with a weakened periodontium. The current controversy of incorporating implants in the patient requiring splinting was discussed, and recommendations are made. Dentists are encouraged to explain all potential ramifications of splinting with fixed partial dentures, including cost, frequency of office visits, and potential alterations or remakes of the prosthesis should physiologic demands surpass the capabilities of the remaining teeth.

Maintaining the oral health of splinted teeth.

The combined and concerted efforts of patients and providers in poststabilization maintenance promote long-term health for the dental splint and its surrounding and supporting soft and hard tissues. Dental splints that are properly placed and contoured enable effective patient self-care and contribute to a positive prognosis. The provider's role in fabrication, placement, and oral hygiene instruction cannot be overemphasized. Professional follow-up concerning periodontal and caries risk assessment, periodontal débridement, and needed preventive interventions are critical to splint longevity. Continued success cannot occur without scrupulous patient self-care. The professional team must provide patients with comprehensive oral care instruction. A host of home care aids are available to assist patients in effective home care practices. With the combination of proficient clinical skill, appropriate dental material selection, good communication, and comprehensive health education, both providers and patients can benefit from esthetic, functional, and healthy dental splints.

Antegrade intramedullary splinting or percutaneous retrograde crossed pinning for displaced neck fractures of the fifth metacarpal?

INTRODUCTION: It is generally accepted that severely displaced or malrotated neck fractures of the fifth metacarpal should be treated by closed reduction and pinning. As antegrade intramedullary splinting avoids adhesions of the extensor hood and provides intramedullary stability this technique seems to be advantageous in comparison with traditional retrograde percutaneous crossed pinning. We raised the question whether the antegrade technique would give clinical and radiological results superior to the retrograde technique and investigated this within a comparative clinical study. MATERIALS AND METHODS: Thirty patients with displaced neck fractures of the fifth metacarpal who received operative treatment were included in a retrospective cohort study. Data was analysed from medical records and a clinical and radiological outcome evaluation was performed. Fifteen patients had antegrade intramedullary splinting and fifteen patients retrograde percutaneous pinning. Median time for follow-up was 17 and 18 months, respectively. RESULTS: A significantly better outcome was found after antegrade splinting for ROM restriction of the metacarpophalangeal joint (0 degrees vs. -15 degrees ; P = 0.016), shortening (P = 0.029), pain (0 vs. 5; VAS 0-100; P = 0.026), and overall assessment by the Steel score (400 vs. 357; P = 0.001). There was no statistical difference in grip strength and functional assessment by the DASH score. CONCLUSION: From our clinical and radiological data we conclude that antegrade intramedullary splinting is superior to retrograde percutaneous crossed pinning and thus should be preferentially considered for displaced neck fractures of the fifth metacarpal.

Maxillary traction splint: a cephalometric evaluation.

Orthodontists are particularly interested in knowing exactly what skeletal and dental changes are produced by headgear. With headgear and fixed appliances, part of the observed change is due to the headgear, part to the fixed appliances, and part to growth. Since the maxillary traction splint moves the teeth en masse, the dentoskeletal changes are due primarily to the headgear force. Selective mandibular dental changes can be produced by adjusting the mandibular occlusal contacts against the splint. In this study forty-seven patients with maxillary dentoalveolar protrusions and Class II, Division 1 malocclusions were treated with orthopedic headgear that attached to a full-coverage maxillary occlusal splint. Fifty-two patients were selected as a control for evaluation of growth changes versus treatment changes. Lateral cephalograms were taken before and after treatment, and the sagittal skeletal and dental changes were evaluated and quantified. The results of the investigation revealed (1) the establishment of a Class I posterior occlusion, (2) a significant overjet reduction, averaging 4.24 mm, (3) inhibition of vertical development of the maxilla and slight intrusion of the maxillary dentition, (4) overbite reduction by leveling of the mandibular dentition, (5) no indication that mandibular growth is accelerated, and (6) no significant increase in the mandibular plane angle. The maxillary traction splint is an effective means of correcting maxillary dentoalveolar protrusion in growing patients prior to fixed appliance therapy. The second phase of treatment with fixed appliances is necessary for individual tooth positioning and for detailing the occlusion.

Effect of prosthetic airway splint on the growing trachea.

Airway splints are now used clinically to treat tracheomalacia and may also have a place in the management of tracheal stenosis. These studies in 5 to 7 Kg piglets were designed to assess the effects of prosthetic airway splints on airway growth and to establish their usefulness in the reconstruction of tracheal defects. Three experimental groups were studied: group I (n = 8). Silastic reinforced Marlex mesh or Vicryl mesh prostheses were placed around 75% of the circumference of a 3 cm segment of trachea. Pigs were sacrificed at 4 months (average weight = 78.9 +/- 9.0 Kg) and the cross-sectional area of trachea was measured. Group II (n = 5). The same prostheses were used to replace the tracheal defect created by excising three rings (50% of tracheal circumference). Tracheas were examined grossly and histologically at sacrifice. Group III (n = 5). Same as Group II except tracheal defect covered by strap muscles. Prostheses placed external to them to prevent airway collapse. Group I had 4% to 14% (mean 8%) decrease from normal cross-sectional area of trachea at site of splint. No airway obstruction and no infection was encountered. Group II, severe airway obstruction, granulation tissue, and infection at site of defect was noted. Group III showed no signs of airway obstruction, no infection, and minimal airway narrowing. Re-epithelialization of the muscle surface in contact with airway occurred in all these animals. Silastic reinforced Marlex or Vicryl splints placed around the intact rapidly growing trachea do not significantly limit its growth. In addition, these synthetic materials appear to be well-tolerated when used to reconstruct tracheal defects if placed over well-vascularized tissue such as muscle.

The conversion of air splints to provide buildup bolus in the treatment of extremities with skin involvement.

An alternate method for bolusing superficial skin lesions of extremities during photon beam treatment was reviewed. Emergency first-aid air splints were filled with water and used as bolus in the treatment of a Kaposi's sarcoma of the leg. Large parallel-opposed 6-MV photon beams were employed. Sheets of bolus were placed under the air splint bolus to ensure coverage of the posterior skin surface. Computerized tomography was performed demonstrating conformity of the air splint bolus to the leg. A diode measurement verified adequate dose to the skin. The results confirm that by adding water to an emergency first-aid air splint to use as bolus was practical, reproducible, and aided in the accurate delivery of a homogenous dose to the skin surface of involved extremities.

The relationship of heel contact in ascent and descent from jumps to the incidence of shin splints in ballet dancers.

I conducted a study to determine whether ballet dancers with a history of shin splints make heel contact on ascent and descent from jumps less often than dancers without this history. Sixteen dancers were filmed as they executed a sequence of jumps at two different speeds. Eight of the subjects had a history of shin-splint pain; eight had no such history. The film was viewed on a Super 8 movie projector. Heel contacts on ascent and descent from jumps were counted. Double heel strikes (heel rise between landing and pushing off) were also counted. A nonparametric t test showed no differences between the two groups in the number of contacts on ascent or descent. The dancers with a history of shin splints, however, demonstrated more double heel strikes (p = .02) than the other group. Clinically, this finding may represent a lack of control or a tight Achilles tendon or both. Further study is necessary to confirm these theories. For treatment and prevention of shin splints, a clinician must evaluate a dancer's jumping technique and then provide systematic training to develop the skin strength, flexibility, and coordination that make up control.

A modified occlusal splint to avoid tracheotomy for total midface osteotomies.

A modified occlusal splint is described which may be used to avoid tracheostomy when a total midface osteotomy is required. We demonstrate the accuracy of the modified splint by using the technique in a control subject who underwent alginate impressions, dental casts, and a face-bow transfer. A modified splint was constructed on the articulated dental models and was found to be accurate within the range of rotational movement of the temporomandibular joint. The technique is demonstrated in a patient with Crouzon's syndrome undergoing cranial vault reshaping and a monobloc (midface) advancement. The modified occlusal splint provides an alternative method of airway management when precise intraoperative occlusal relationships are important.

The prevention of shin splints in sports: a systematic review of literature.

PURPOSE: To review the published and unpublished evidence regarding risk factors associated with shin splints, assess the effectiveness of prevention strategies, and offer evidence-based recommendations to coaches, athletes, and researchers. METHODS: We searched electronic data bases without language restriction, identified citations from reference sections of research papers retrieved, contacted experts in the field, and searched the Cochrane Collaboration. Of the 199 citations identified, we emphasized results of the four reports that compared methods to prevent shin splints. We assessed the methodologic quality of these reports by using a standardized instrument. RESULTS: The use of shock-absorbent insoles, foam heel pads, heel cord stretching, alternative footwear, as well as graduated running programs among military recruits have undergone assessment in controlled trials. There is no strong support for any of these interventions, and each of the four controlled trials is limited methodologically. Median quality scores in these four studies ranged from 29 to 47, and serious flaws in study design, control of bias, and statistical methods were identified. CONCLUSION: Our review yielded little objective evidence to support widespread use of any existing interventions to prevent shin splints. The most encouraging evidence for effective prevention of shin splints involves the use of shock-absorbing insoles. However, serious flaws in study design and implementation constrain the work in this field thus far. A rigorously implemented research program is critically needed to address this common sports medicine problem.

Shin splints--a review of terminology.

This review is intended to improve the understanding of and rationale for the use of the term shin splints. Currently the term is used widely and variably, with little consensus of definition. Broadly, it denotes the occurrence of exertional lower leg pain; more specifically, it refers to an anatomical site of periostitis. The literature reports a multiplicity of descriptions and definitions of shin splints resultant from the complex etiologies and differing perceptions of these conditions. It is proposed that the term shin splint be recognized as generic, rather than diagnostic, and that specific conditions that currently exist under this term be differentiated. The etiology and interaction of these related conditions are considered, and a classification based on the current literature is given of conditions currently termed shin splints, providing a rationale for their clinical presentations, investigative findings, and interactions.

The influence of splinting procedures on the periodontal and peri-implant tissue damping characteristics. A longitudinal study with the Periotest device.

The aim of the present study was to evaluate the capability of the Periotest device in detecting and monitoring functional changes in the periodontal as well as in the pari-implant damping characteristics. In the first part of this study, 107 teeth were splinted by means of 40 full acrylic fixed prostheses (AFP) and another 37 teeth were splinted by means of 14 ceramometallic fixed prostheses (C-MFP). The Periotest measurements of individual teeth were done the day the fixed prostheses were cemented temporary (PTV 1), and again after a mean observation period of 27.4 days (PTV 2). In the 2nd part, 78 osseointegrated two-stage implants were splinted by means of 23 full acrylic fixed prosthesis (AFP) and other 18 implants were left without it. Using the same abutment length, Periotest measurements were performed, at abutment connections and before installation of the final prosthesis. In a 3rd part, using both implants and teeth as abutments, 29 osseointegrated implants were connected with 25 abutment teeth by means of 7 AFP. The measurements were performed at the beginning of the prosthetic treatment and 2, 4 and 6 weeks later. After splinting teeth by means of AFP for the observation period, no statistically significant reduction in PTVs was found. When on the other hand, a C-MFP was used, PTV 2 showed a significant reduction. The PTVs at abutment connection went down after a period of time, during which some implants were interconnected by means of an AFP and others were not.(ABSTRACT TRUNCATED AT 250 WORDS)

Nonlinear finite element analysis of a splinted implant with various connectors and occlusal forces.

PURPOSE: The aim of this study was to analyze the biomechanics in an implant/tooth-supported system under different occlusal forces with rigid and nonrigid connectors by adopting a nonlinear finite element (FE) approach. MATERIALS AND METHODS: A model containing 1 Frialit-2 implant (placed in the second molar position) splinted to the mandibular second premolar was constructed. Nonlinear contact elements were used to simulate a realistic interface fixation between the implant body and abutment screw and the sliding keyway stress-breaker function. Stress distributions in the splinting system with rigid and nonrigid connectors were observed when vertical forces were applied to the tooth, pontic, implant abutment, or complete prosthesis in 10 simulated models. RESULTS: The displacement obtained from the natural tooth increased 11 times than that of the implant, and the peak stress values within the implant system (sigmaI, max) increased significantly when vertical forces acted only on the premolar of a fixed prosthesis with a rigid connector. The sigmaI, max values seen in the splinting prosthesis were not significantly different when vertical forces (50 N) were applied to the pontic, molar (implant) only, or the entire prosthesis, respectively, regardless of whether rigid or nonrigid connectors were used. Moreover, the peak stress values in the implant system and prosthesis were significantly reduced in single- or multiple-contact situations once vertical forces on the pontic were decreased. DISCUSSION: The compensatory mechanism between the implant components and keyway sliding function of the implant/tooth-supported prosthesis could be realistically simulated using nonlinear contact FE analysis. The nonrigid connector (keyway device) significantly exploited its function only when the splinting system received light occlusal forces. CONCLUSION: Minimization of the occlusal loading force on the pontic area through occlusal adjustment procedures to redistribute stress within the implant system in the maximum intercuspation position for an implant/tooth-supported prosthesis is recommended.

[Effect of the number of splinted abutments on stress distribution of support tissue]

OBJECTIVE:This study applied an SJ-1 bolt attachment partial denture to restorate distal extension edentulous areas.Finite element analysis (FEA) was used to monitor induced around abutment supporting tissues under the different number of splinted abutments.METHODS:Finite element analysis. RESULTS:The result demonstrate that the reduction of the number of splinted unit from three to two resulted in an insignificant increase of stress records,whereas reduction of the number from two to one resulted in a significant increase of stress nine times greater than the three unit splint values.CONCLUSION:Hence,at least two teeth on each side should be splinted when SJ 1 bolt(extracoronal) distal extension attachment prostheses are used.

[A study of the reasonable vertical thickness of stabilization splint]

It was proved in this study through the measurement and calculation of the shape and size of dentition and jaws and the position of the hinge axes that the thickness of stabilization splint was difficult to be confirmed within free way space, it was therefore suggested that attention should be paid on forming a flat and smooth occlusal plane during the design and manufacture of splint, so that the points to a flat plane contact relation could be presented between the split and the tops of working cusps. Guidance effect on inclines must be eliminated. The thickness of splint should depend upon the height of cusp and the overbite degree of the patient, so that free way space wasn't absolutely inviolable in the set of stabilization splint.

[Application of a stent splint to protect intraoral organs from radiation injury in a 97-year-old patient with multiple oral cancers who survived to over 100 years old].

Radiation therapy had been used with increasing frequency in recent years in the management of oral cancers of advanced ages. In those cases we have to take good care to maintain the oral health of patients undergoing cancerocidal dose of radiation therapy. Using splints, as a tissue displacer, during radiation, we could treat a 99-year-old female patient without serious radiation sequelae, successfully she survived over 100 year-old. As she visited us at 97 year-old, the primary lesions located on the left upper lip, nose, upper and lower gums were diagnosed as multiple verrucous carcinoma histologically. Seventeen months after the first radiotherapy to the lip, nose and upper jaw, we planned again radiotherapy to the recurrent tumor of the lower gum. In order to eliminate and minimize side effects of the second irradiation for the contiguous intraoral organs, we devised a splint to exclude the tongue and upper gum apart from a radiation field. The splint, as tissue displacer, was made of heat-cured acrylic resin and divided into two pieces which were formed like full denture without artificial teeth. They were applied to the upper and lower jaws. The lower one had a large wing to exclude the tongue from irradiation field. After setting of the splint, she had been clenched slightly with an aid of chin cap. Then we could finish successfully the radiotherapy with 10 MV X-ray 40 Gy as scheduled without serious troubles.

[Experience with the internal splinting method (endoprosthesis) (author's transl)].

We have used internal splints for 20 years; the endoprosthesis creates an internal urinary diversion of dilatated kidneys due to incurable gynecological, prostatic and bladder cancer. Also in pyeloplasties, difficult stone operations and retroperitoneal fibrosis the pyelovesical splinting method is useful. Scanning electron microscopic research shows that incrustations are rare and even not existing if siliconised polyvinylchlorid (PVC) splints are used. The so called "pig-tail"-splint (double-JTM-ureteral stent) is of pure silicone material and therefore well fit for therapy even over a longer period.

[A method of using intraluminal splints in the treatment and prevention of recurrent ileus of the small intestine].

The authors present a group of 23 patients where splints were used in the loops of the small intestine. The group is divided into two sub-groups. The first one comprises patients where the splint was inserted because of relapsing ileus of the small intestine after previous surgical operations. The second sub-group comprises patients where this operation was performed either preventively or as part of a primary operation or as part of a reoperation called for by complications immediately preceding operation. The internal splint is inserted via jejunostomy and through the loops of the small intestine it is guided by means of a sutured Foley catheter which after proper insertion of the splint is left in the caecum. The authors emphasize the importance of effective decompression of the small intestine during the early postoperative period which is made possible by suction of the ileous contents through lateral openings of the inserted probe. After three years' work, using this method, the authors confirm that it gives good results.

Mandible fragment fixation during reconstruction: the splint-and-plate technique.

One of the most popular methods of mandible fragment fixation is the precontoured reconstruction plate technique. Unfortunately, this method is not a reliable option when tumor distorts the mandibular contour or extends through the buccal cortex of the mandible. An alternative to the precontoured reconstruction plate is the splint-and-plate technique of mandible fragment fixation. An application of this appliance and method in 10 patients revealed the technique's advantages. The splint can be applied quickly and does not obstruct the ablative or reconstructive procedure. Further, the splint accurately keys the dentition and reliably maintains temporomandibular joint relationships. Finally, this technique provides a reference point to the exact position of the symphysis and angle when these landmarks have been resected.
