PROBLEM TO BE SOLVED: To provide an inexpensive dental brace which facilitates attaching of a wire and gives little uncomfortable feeling to a user when attaching the wire to a dental brace.SOLUTION: The dental brace comprises a base section 10 having a prismatic shape and a stopper 20. The base section has a front end with an insertion groove 11 of a wire and a rear end with an attachment face 12 to be attached to a tooth via an adhesive. The stopper is arranged detachably on the front end of the base section and prevents coming off of the wire inserted into the insertion groove 11 from the insertion groove. The stopper has a blocking plate 21 arranged opposite to the insertion groove for blocking at least a part of the insertion groove, first and second layering plates 24-1 and 24-2 projecting in a shape of a gate from the blocking plate, and engaging nails 25-1 and 25-2 formed on the distal ends of the layering plates respectively for engaging with the base section. Engaging grooves 15-1 and 15-2 that engage with the engaging nails respectively are formed transversely on side faces of the base section, and a slit 19 is formed on at least one of the side faces having the engaging grooves.COPYRIGHT: (C)2008,JPO&INPIT【課題】歯列矯正具にワイヤを装着する際に、極めて容易に装着可能とすることによって、低コストであって、しかも被矯正者が不快感を覚えることがない歯列矯正具を提供する。【解決手段】ワイヤの挿入溝11を前端に設け、接着剤を介して歯に接合される接合面12を後端に設けた角柱状の基台部10と、この基台部の前端に着脱自在に装着して挿入溝11に挿入されたワイヤの挿入溝からの脱落を防止するストッパー20を備え、ストッパーは、挿入溝に対向させて配置して挿入溝の少なくとも一部を閉塞する閉塞板21と、この閉塞板から突出させた第1の重合板24-1と第2の重合板24-2とにより門型状とするとともに、各重合板の先端には基台部と係合する係合爪25-1,25-2を設け、基台部には、側面に係合爪とそれぞれ係合する係合溝15-1,15-2を横断状に設けるとともに、この係合溝が形成された側面の少なくとも1つにスリット19を設ける。【選択図】図2
