The study was undertaken to evaluate light cure resin as an alternative to a current self cure material. Light cure materials are supplied by the manufacturer ready mixed in the form of sheets, rope or gel as opposed to the raw chemicals which have to be mixed before or during use. Laboratory tests showed that, on average the two light cure resins tested deflected more, had a significantly lower impact resistance and had a significantly harder surface than the self cure material. From the dental technician's point of view light cure materials are easier to adapt and a good reproduction of the fitting surface is achieved. In the gel form the material can be adapted in layers to achieve the desired thickness but care must be taken to avoid internal voids caused by over adaption. It can be adapted trimmed and polished significantly quicker than the conventional self cure powder and liquid. The main disadvantage of light cure materials is the fine dust produced when trimming as opposed to the shavings with conventional acrylics. The light cure material which performed better in the laboratory tests (Thixotec) was compared with the conventional self cure resin (Orthoresin) in a clinical study. A total of 25 patients participated between January 1994 and March 1996. A series of questionnaires was completed at various stages of treatment. The results showed that there was no significant difference in the patients' acceptance of the two materials. Although there were more breakages to the light cure material the number was small. Light cure resin, therefore, has considerable potential for wider use in orthodontics by virtue of its less toxic handling properties and its comparable clinical performance to self cure resin.
