Abstract:
Apparatus is provided that includes a dental implant having a proximal implant end and a lateral external surface. The implant is shaped so as to define a lumen therethrough having a lateral opening through the lateral external surface. The apparatus further includes an applicator, which is removably coupled to the proximal implant end. The applicator includes a delivery tube having a distal tube end that is removably coupled to the implant such that the delivery tube is in fluid communication with the lumen via the lateral opening. Other embodiments are also described.
Abstract:
Fastening apparatus includes a fastener (30, 64, 120), including a threaded shaft (34, 126) having a thread diameter and a fastening element (36, 68, 124) having a head diameter, greater than the thread diameter. An annular washer (38, 40, 66, 70, 90, 100, 110, 122), including a shape memory material, is configured to fit over and surround the shaft and has an outer diameter no greater than the head diameter.
