1. Apparatus comprising:
- a dental implant having 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 being 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; and
a delivery tube having a proximal tube end and a distal tube end, which distal tube end is removably coupled to the implant such that the delivery tube is in fluid communication with the lumen via the lateral opening when the delivery tube is coupled to the implant,wherein at least a portion of the lateral external surface is shaped so as to define a screw thread, andwherein the lateral opening is within the portion of the lateral external surface that defines the screw thread.

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.

11. A method comprising:
-
providing a dental implant having 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 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; forming a bore through a maxillary alveolar ridge; inserting the implant into the bore at least until the distal opening comes into fluid communication with a surface of a Schneiderian membrane facing the ridge; raising the membrane to form a cavity between the ridge and the membrane; after raising the membrane, injecting a regenerative material into the cavity via the lumen; and after injecting the material, further rotating the implant until the lateral opening is positioned entirely within at least one location selected from the group consisting of;
the bore in the ridge, and the cavity between the ridge and the membrane. - View Dependent Claims (12, 13, 14, 15, 16)
