<p>PURPOSE:To use an artificial dental root stably from the beginning of implantation without an unpleasant feeling by dispersing stress throughout a blade by a method wherein two blades are provided to the base part performing the bridge connection of an implanting part in a shape opposed to each other almost in parallel and forming the outer edge of the leading end of each of the blades into an uneven shape of a gentle curve. CONSTITUTION:Two blades 4 of an implanting part are provided to a base part performing bridge connection so as to form a horizontal U-shaped cross-section in opposed relation to each other almost in parallel. The implant in an alveolar bone is strongly fixed and held to the bone by two blades 4 and the base part thereof. When a crown is bonded to the head part 5 of the implant implanted with enhanced holdability to be held thereto, the outer edge of each of the blades 4 is formed into an uneven shape of a gentle curve and a recessed part 4C is formed directly under the connection part on which pressure acts and this part is elastically collapsed by about 20-50mum by pressure to make it possible to receive pressure and there is no place where stress acts on the blades 4 collectively and pressure can be dispersed throughout the implant. A shock or vibration is retrieved by this buffer effect and this implant can be stably used from the beginning without bringing about an unpleasant feeling.</p> |
