We examined the clinical performance and tissue compatibility of the new synthetic resin CMO-4S for use in dental splints. Clinical observations were made of 34 subjects before insertion of the splint, immediately after insertion, and then at one and three months. Thirty-two of the subjects received stabilization type splints and the other two, repositioning splints. All of the splints were removable. Post-treatment observation of the gingival margin and oral mucosa revealed that CMO-4S had no harmful effect on the soft tissue. Twenty-eight of the splints provided proper adaptation and required no adjustment of the inner surface. Even in the six splints that were loose, proper adaptation was obtained with adjustment of the inner surface. Twenty-nine of the splints were lacking luster even at the time of placement, and an additional three more lost luster during use. This suggests a need for adequate polish. No cases of significant clinical abrasion were noted during the clinical trials. Although slight discoloration was noted in 32 of the cases one month after placement, this posed no clinical problem. Fractures were observed in 6 of the 34 cases at three months. Only two of the patients complained of discomfort to the tongue immediately after placement of the splint.
We concluded that CMO-4S is safe and effective for use as a splint material.
