Caution: The bone near the sinus may be more porous than that in the canine-incisor area. The socket should be drilled accordingly, being left slightly shallower in the porous area. When seating the bladevent balanced tapping is essential. The blade should not ride up and down in its socket. Both posts of the bladevent should be flush with the reduced crest (4) .

Although a double-posted bladevent is preferable when two anterior abutments are desired, a narrow "waist" extending high on the ridge can divide the ridge into two implant sites. Because each site is separate, various "tricks" may be used to take better advantage of the remaining bone. The sockets may follow the dental arch (5) ; or, a socket may be angled (6) or curved (7) across the dental arch. Angling or curving a bladevent in a short space is recommended only for the experienced operator.

Sometimes it is possible to reduce (8) the more anterior site to extend a larger implant into the narrow waist. It is usually unwise to reduce the ridge near the sinus (9), unless the ridge is tall. Caution: Do not improperly seat one implant in order to achieve even post height. Each implant must be buried up to the bottom of its post. Differences in post height (10, 11) can be easily compensated in the prosthesis.
