should protrude at fairly symmetrical intervals, ideally, the anterior posts into the cuspid regions and the posterior posts into the bicuspid-molar areas. The six posts may arise from any combination of implants.

The following figures show various longitudinal sections, cross-sections, and clinical views of the bladevent implant.   

Figure 1, shows how deep and clear the groove should be made to accommodate the blade implant.

Figures 2, 3, 4, reveal how the osseous regeneration of bone takes place at the vent portion of the implant (A) and over the shoulders (Ai) . (B) shows how the muco-periosteal tissue adapts to the posts. (C) shows how the shoulder of the blade should be buried below the level of the alveolar crest, and (D) how the bottom of the post seats right on the bone.

Figure 5, shows the cross-section of the blade implant, showing how the blade stabilizes itself against masticatory forces. The arrows show how it counteracts and prevents the implant from moving.

Figure 6, shows the parallelism of the posts to one another, which is very important for the final prosthesis.

These all lead to successful implantology.

The mandibular anterior implant groove for a single posted bladevent is started about 2-3 mm. away from the midline (1), and follows the curvature of the arch posteriorly. A 700 XL bur is used in a contra-angle (2) Copious amounts of water (3) direct-
