Endosseous blade implants 527

Fig. 11-206. The single tooth blades in the maxillae help stabilize anterior periodontally involved teeth. Some of these blades are obliquely set to avoid the maxillary sinus. In the mandible mesiodistal blades act as posterior abutments.

Fig. 11-207. These asymmetrical blades were specially designed to avoid penetrating the sinuses yet give maximum contact with bone.

Fig. 11-208. Another series of blade designs. In this maxilla there is a mesiodistal blade in the right tuberosity, an obliquely placed buccopalatal blade in the right bicuspid area avoiding the sinus, a single tooth blade in the left central incisor region, and a transverse oblique, mesially directed blade in the left second bicuspid area avoiding the anterior extent of the antrum. The mandible contains a mesiodistal blade.
