Vertical Ridge Augmentation With Mandibular Lingual Torus Block Graft

Figure 1. Pre-operative clinical and radiographic examination. (a and b) Clinical examination revealed vertical deficiency over an edentulous ridge for future implant site #30 and prominent tori lingual to the mandibular premolars. (c) Radiographic film demonstrated vertical ridge deficiency and radiopacity corresponding to the lingual tori. Figure 2. Mandibular vertical ridge augmentation with lingual tori. (a) Lingual view after full-thickness flap elevation. (b) Decortication of the recipient site and preparation for the screw holes on torus. (c) Adaptation and fixation of the tori block graft (lingual view). (d) Particulate bone graft in place. (e) Fixation of the resorbable collagen membrane. (f) Suture of the surgical site.

Figure 3. Radiographic examination of the vertical ridge augmentation. (a) Immediate after the procedure. (b) Six-week postsurgical procedure. (c) Eight-month follow-up revealing integration of the tori block. Figure 4. Implant placement after 8 months. (a) Significant clinical vertical ridge augmentation was noted. (b and c) Buccal and occlusal views after implant placement. Vertical augmentation with successful integration of the tori block graft resolved the deficient ridge for proper implant placement.

Distal crestal bone was intentionally reduced to facilitate soft tissue cleft closure.
