Abstract: A method is provided that includes injecting, from a first side of a bone, through (a) exactly one bore that passes through the bone from the first side to a second side of the bone, and (b) into a cavity adjacent to the second side of the bone, a solid-liquid composition of solid particles and a physiological liquid solution. The physiological liquid solution is drained from the cavity and through the bore while passage of the solid particles of the solid-liquid composition is inhibited, such that the solid particles accumulate in the cavity.

Abstract: An osteotome is shaped so as to define (a) a lumen through the osteotome, a distal end of the lumen opening through a distal opening disposed within 10 mm of a distal end of the osteotome, and a proximal end of the lumen opening through a proximal opening disposed at least 5 mm proximal to the distal opening, (b) a lateral external surface, at least a portion of which is shaped so as to define a screw thread that (i) has a distal thread end that is disposed within 10 mm of the distal end of the osteotome, and (ii) comprises one or more raised helical ribs going around the osteotome, and (c) one or more longitudinal drainage slots, which extend along at least respective longitudinal portions of the osteotome having respective longitudinal lengths of at least 5 mm, measured parallel to a central longitudinal axis of the osteotome.

Abstract: Apparatus is provided that includes a surgical tool for use with solid particles and a physiological liquid solution. The surgical tool includes (a) a shaft unit, which is shaped so as to define a delivery lumen, and a distal opening, which is disposed within 10 mm of a distal end of the shaft unit, in fluid communication with the delivery lumen; (b) a composition source, which is coupled in fluid communication with the delivery lumen, and which is configured to provide a solid-liquid composition of the solid particles and the physiological liquid solution; and (c) a pump, which is configured to pump the solid-liquid composition through the distal opening via the delivery lumen.

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: A method is provided that includes advancing a drill having a distal end through an occlusal cortex into trabecular bone of an alveolar ridge, and ceasing the advancing of the drill when the distal end of the drill reaches an occlusal surface of a superior cortex of the alveolar ridge. Other embodiments are also described.

Abstract: Apparatus is provided that includes a dental implement, which is shaped so as to define a lumen therethrough, a distal end of which lumen opens through at least one distal opening on a distal end of the dental implement; and a lateral external surface, at least a portion of which is shaped so as to define a screw thread that extends until the distal end of the dental implement. Other embodiments are also described.

Abstract: Apparatus is provided that includes a dental implant having 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 a retaining element, and a delivery tube having a distal tube end. The retaining element is configured to assume (a) a first position in which the retaining element removably couples the distal tube end to the implant such that the delivery tube is in fluid communication with the lumen via the lateral opening, and (b) a second position in which the retaining element does not couple the distal tube end to the implant. Other embodiments are also described.

Abstract: Apparatus is provided that includes a dental implant having a central longitudinal axis, a lateral external surface, and a distal implant portion that extends from a distal implant end along up to 50% of a longitudinal length of the implant. The implant being shaped so as to define a lumen therethrough having (a) at least one distal opening through a distal external surface of the distal implant portion, and (b) a lateral opening open to the lateral external surface. The implant is also shaped so as to define a recessed surface that (a) is recessed from the lateral external surface, (b) is outside of the lumen, and (c) completely surrounds the lateral opening. Other embodiments are also described.

Abstract: A minimally-invasive sinus lift implant and implantation methods are disclosed. An implant apparatus may included an anchor having a distal implant end and an opposite proximal end. The implant apparatus may further include a channel extending though a portion of the anchor and having an outlet opening in the distal implant end. The channel may also include an inlet opening on a side of the anchor between the distal implant end and the proximal end. Further, the inlet opening, the channel, and the outlet opening may be configured to convey fluid therethrough and the implant is configured for implantation in a bone such that when fully implanted, the side inlet opening is buried in the bone.

Abstract: A dental implant is provided that has a proximal-most part, a lateral external surface, and a distal implant portion that extends from a distal implant end along up to 50% of a longitudinal length of the implant. The implant is shaped so as to define a lumen therethrough (a) having at least one distal opening through a distal external surface of the distal implant portion, (b) having a lateral opening through the lateral external surface, and (c) not open to a proximal external surface of the implant within 2 mm of the proximal-most part of the implant. Other embodiments are also described.
