Splints made of wire and composite: an investigation of lateral tooth mobility in vivo 总被引:1,自引:0,他引:1
Abstract In 103 posttraumatic splints, lateral tooth mobility was measured with Periotest immediately before and after the routine splint removal. The splints were made of composite resin and an 0.017×0.025″ orthodontic steel wire. 481 teeth were measured. A statistic evaluation revealed that the immobilisation effect did not exceed normal tooth firmness. Fixation to one neighbouring tooth had less effect than fixation to two. Adjacent tooth gaps reduced the effect. Splint extensions had no influence. With the use of the Periotest device, more than 50% of all teeth with a true mobility of 20 Periotest-units or more were detectable as mobile in spite of the fixed splint. 相似文献

Neurogenic heterotopic ossification is a process of abnormal bone formation of multi-factorial aetiology. It occurs at varying sites to produce deformity and restriction of joint movement, and has a major impact on physical ability. There is extensive literature on the medical management of heterotopic ossification, but the role of physiotherapy is poorly described.This article aims to illustrate the importance of proactive physiotherapy in the team management and treatment of this condition. The authors show that physiotherapy is not contra-indicated in the presence of neurogenic heterotopic ossification and illustrate how interventions for improving range of movement can be used. The authors suggest that integrated team management was essential to the successful outcomes in these complex cases. 相似文献

BACKGROUND: The present case report describes a 1-year follow-up of functional rehabilitation of a young periodontal patient with severely advanced, rapidly progressing marginal bone loss treated by using a new splinting material, i.e., glass fiber-reinforced composite (FRC). Apart from one single tooth, the young man had retained all his natural teeth. TREATMENT: Periodontal treatment was based on cleaning and root planing enabled by partial-thickness-flap operations. This method was selected to avoid further damage to the remaining alveolar bone. After healing for 6 months, a cavity retained internal FRC splint was constructed and 1 missing lower molar was replaced by an inlay-retained FRC resin-bonded fixed partial denture (FPD). A 12 months follow-up period revealed a healthy periodontium and good functional and esthetic results. CONCLUSIONS: The new material allows the use of periodontal treatment methods instead of prosthetic alternatives, which until now have been a more generally used approach in the treatment of severely advanced periodontal cases. Internal fiber-reinforced composite splinting being affordable for the patient, easy for the clinician to construct and giving good esthetic and functional results, suggests that the method may be a valuable aid in periodontal treatment. 相似文献

The purpose of this study was to determine if fixed splinting of teeth with intraoral wire and acrylic splints had advantages with respect to tooth mobility, bone level and attachment level over unsplinted teeth following osseous surgery. Ten patients were chosen who exhibited bilaterally similar chronic destructive periodontitis and mobile teeth. One maxillary sextant was splinted, while the other was unsplinted. Both sextants functioned against an unsplinted mandibular arch. Following initial therapy, osseous surgery was performed in both maxillary sextants on the same day. Tooth mobility data was collected 1 week before and at 3, 6, 12, and 24 weeks following surgery. Levels of gingival attachment and bone were recorded before and 24 weeks after surgery. Splints were removed before measurements, then replaced, and the occlusion refined. Prophylaxes and oral hygiene instruction were repeated every 3 weeks throughout the study. For all categories of teeth and mobility examined, tooth mobility increased initially after surgery and subsequently decreased by 24 weeks to about presurgical values. The splinted and unsplinted segments reacted similarly throughout the study; splinting did not significantly reduce the mobility of individual teeth. Pre- and postsurgical bone and gingival attachment levels were also similar for the splinted and unsplinted segments. 相似文献

This paper compares the immediate effects of dorsal, volar and no splints in reducing hypertonicity in the wrist flexors of spastic hemiplegic subjects. The measures include: (i) passive range of motion; (ii) angle of point of stretch reflex; (iii) resistance to passive wrist extension; and (iv) force of spontaneous wrist flexion. Results of this study indicate a significant reduction in hypertonicity following both dorsal and volar splint application on the passive range of motion and resistance to passive extension measures (P < .05), and a significant reduction in hypertonicity as measured by spontaneous flexion following two hours of dorsal splint wearing (P < .05). No significant reductions in hypertonicity were noted on the angle of point of stretch reflex measure, and on the force of spontaneous flexion measure. Possible explanations for results and suggestions for further resarch are discussed. 相似文献

Objective: The purpose of this study was to qualitatively describe the underpinnings of the successful implementation of a collaborative prehospital spinal immobilization guideline throughout the emergency medical services (EMS) community in two counties in Colorado. We also describe lessons learned that may be beneficial to other communities considering similar initiatives. Methods: Qualitative data were collected from key informants who were directly involved in the implementation of a new prehospital spinal immobilization guideline among four community hospitals in two different hospital systems and the associated EMS providers within the two counties. We interviewed a purposively selected sample of emergency department (ED) physicians and other ED staff, hospital decision makers, EMS educators as well as fire department and EMS medical directors. Data were collected and reviewed until saturation was achieved. We conducted qualitative analysis to summarize and synthesize themes. Results: Ten key informants were interviewed, at which point saturation was achieved and several clear themes emerged. Participants described successful community-wide guideline implementation despite a history of competition, isolation, and conflict between the various EMS organizations and hospitals on past EMS and trauma initiatives. Factors related to success included the nearly universal perception that the initiative was “cutting edge” and thus an important paradigm shift in care for the community, as a whole. Participants reported the ability of community stakeholders to jointly assure a collaborative approach, characterized by intensive education for EMS personnel and others involved, and the ability of the community to together secure the new equipment required for success. Conclusions: Key informants described a convergence of factors as leading to the successful implementation of a prehospital spinal immobilization guideline. Lessons learned regarding how to overcome a tradition of competition and isolation to allow for success may be useful to other communities considering similar initiatives. 相似文献
