Patent number: 10729519Abstract: There is provided an implant having a slack prevention function by an eccentric fitting structure. An engaging shaft 53, which is decentered with a screw shaft 52, is provided at the end of an abutment screw 5, and is engaged with an engaging hole 45 provided in the bottom of a screw hole 44, into which an abutment screw 5 is screwed, and thus, the screw shaft 52 is inclined to and eccentric from the screw hole 44. Thereby, the screw shaft 52 comes to be strongly pressed partially in a circumferential direction toward the screw hole 44, so that internal stress in the horizontal direction is accumulated on the screw shaft 52. The screw 5 is threaded with maintaining prevailing torque caused by the internal stress, which enables the screw 5 to be fastened to the right position.Type: GrantFiled: January 6, 2016Date of Patent: August 4, 2020Assignee: Hardlock Industry Co., Ltd.Inventor: Katsuhiko Wakabayashi

Patent number: 10603140Abstract: It is disclosed a dental implant (130; 230; 330) for promoting hone growth. The dental implant includes an elongated implant body having a coronal end portion (131; 231; 331) and an apical end portion (132; 232; 332), at least one external thread (140; 240; 340) and a flute arrangement having a depth. The flute arrangement has at least two helical flutes (150; 250; 350) that spiral in the general direction of said at least one external thread (140; 240; 340). The flutes (150; 250; 350) propagate with a greater lead than said at least one thread (140; 240 340). The flute arrangement is capable of scraping off and transferring bone debris in the coronal direction of the implant during insertion. It is also disclosed a method of using the dental implant and an implant system according to the present invention.Type: GrantFiled: March 5, 2015Date of Patent: March 31, 2020Assignee: Nobel Biocare Services AGInventors: Jan Hall, Fredrik Kullberg

Patent number: 10537373Abstract: An implant having a porous portion with a plurality of interconnected voids for receiving at least one injectable substance such that an injectable substance can elute from the porous portion. A syringe can be inserted into the at least one porous portion for administering the at least one injectable substance into the voids of the porous structure. The implant can be implanted with the at least one porous portion pre-loaded with the at least one injectable substance. The at least one porous portion can be loaded by inserting the syringe into the at least one porous portion after implanting the implant. The porous portion can be re-loaded with the syringe after the at least one injectable substance has eluted from the porous portion or replaced with a different injectable substance.Type: GrantFiled: April 22, 2016Date of Patent: January 21, 2020Assignee: Biomet Sports Medicine, LLCInventors: Jacy C.
