The use of vacuum-molded polyvinyl acetate-polyethylene copolymer (PVAC.PE) for a handicapped patient.

This paper provides a survey of recent literature on the use of mouth sticks for patients who have little or no use of their limbs. Criteria for mouth stick design, types of appliances, and the fabrication of such devices are described. Details are given of a case of a young child with arthrogryposis multiplex congenita, in whom a novel approach was used to allow the safe intra-oral retention of writing implements.

Neuropathological chewing: a dental management protocol and treatment appliances for pediatric patients.

Neuropathological chewing in hospitalized, comatose patients can occur from severe brain damage following a closed head injury, hypoxia, and septic shock. The dental management protocol developed by the Department of Dentistry at the Royal Children's Hospital, Melbourne, Australia, is presented. Treatment appliances utilizing a mandibular cast-silver cap splint with acrylic bite blocks and a maxillary mouthguard with acrylic bite blocks are discussed.

Hypoxemia due to inserting a bite block in severely handicapped patients.

In severely handicapped patients with severe cerebral palsy, stridor can be caused by a bite block in the mouth. So that dental treatment can be performed safely for these patients, the effect of a bite block on the respiratory function of 30 severely handicapped patients was investigated with two pulse oximeters. Of the 30 subjects examined, 96.7% showed SpO2 values above 95% in the resting state, and 26.7% showed SpO2 values under 94% after insertion of a small or middle-sized bite block. Patients who did not show SpO2 decrease while using a small bite block did have deterioration of SpO2 values when a middle-sized bite block was used. According to analysis by AIC, patients whose weight was less tha 20 kg, who were shorter than 130 cm, and who were more severely handicapped tended to have a deterioration of breathing function when using a bite block

Adaptations of mouthguards for patients with special needs.

The adaptations and applications of mouthguard appliances are many and varied, with uses ranging from protective to therapeutic. These modifications serve the individual needs of patients. This requires problem-solving based on combining form and function with the skills of the dentist.

Mouthguards and the role of sporting team dentists.

With the increased popularity of contact sports and encouragement to participate at an early age, the role of the dental profession in relation to prevention of dental and other orofacial sporting injuries has become more important. Provision of professionally-fitted (custom) mouthguards for persons involved in contact sports, recognition of the 'injury prone dentition', and expertise in immediate management of dental injuries form the basis of sports dentistry. The aim of this review paper is to increase professional awareness and interest. Additionally, it is hoped to stimulate dentists to become involved as sporting club consultants.

Forces transmitted through EVA mouthguard materials of different types and thickness.

Previous studies into sporting mouthguards have been mainly attitudinal or epidemiological. The aim of the present study was to build an impact rig to measure the impact absorbed by mouthguard materials of various thicknesses. The acceleration of the pendulum of the rig was measured and used to calculate the force transmitted to the materials. Impact tests were also performed on three commercially available mouthguard materials. Tests showed that the force transmitted through mouthguard materials was inversely related to the material thickness. Mouthguard construction techniques with ethylene vinyl acetate (EVA) plastics should be monitored to avoid occlusal thinning especially on the incisal edges. Thinning results in reduction in the protection offered by the mouthguard.

Prevalence of orofacial injuries and use of mouthguards in high school Rugby Union.

In Australia there is a tradition of early involvement of children in contact sports. Mouthguards are known to reduce the risk of dental and associated injuries--however, Australian studies of the use of mouthguards in contact sports and the prevalence of dental and associated injuries have only focused on adult participants. Previous studies of high school Rugby Union players in New Zealand have shown that between 13 and 15 per cent had previously sustained dental injury while between 30 and 37 per cent wore mouthguards regularly. One hundred and thirty Rugby Union football players attending a large high school in Brisbane participated in this survey. All believed in the safety value of mouthguards in football. All of the players in the four open teams and the majority of players in the four under-age teams wore mouthguards, and the incidence of dental injury was very low, approximately 4 per cent. These and other results will be presented and compared with previous similar studies.

An improved mouthguard material.

A modified mouthguard material which reduces transmitted forces is described. Tests showed that the inclusion of air cells in a 4 mm thick polyvinyl-acetate-polyethylene (EVA) copolymer reduced the effects of impacts of less than 10 kN when compared with a material of the same EVA composition and thickness. The EVA copolymer with air-inclusions is suitable for the construction of stock mouth-formed and vacuum-formed mouthguards. The improved elastic properties of the modified mouthguard material reduced transmitted forces by 32 per cent when compared with traditional EVA mouthguard polymers of the same thickness.

The effect on energy absorption of hard inserts in laminated EVA mouthguards.

One of the suggestions for using laminated mouthguards is the inclusion of hard inserts to improve mouthguard performance. However, there is a paucity of published material on the use of such inserts and this study was designed to investigate this theory. Hard layers of ethylene vinyl acetate (EVA) were included in laminated mouthguard sheets which were then subject to repeated impacts with an impact rig. Hard inserts resulted in reduced energy absorption when compared with a control sheet of the same material and approximate thickness but without the hard inserts. Additionally, the further the hard inserts were located from the impact surface, the least reduction there was on energy absorption.
