28 I I case report _ guided surgery soaked in autologous venous blood. In order to se- cure the graft, it was covered with a further lamella vestibularly, which was fixed with osteosynthesis retaining screws (Fig. 5). This was followed by fully tightening the screws inserted into the gliding holes of the occlusal lamella to compress the particulate graft. This was followed by wound closure with sutures. On the left side, augmentation was performed by apply- ing the tongue-in-groove technique6–8 (Figs. 6–8). Clindamycin 600 mg was administered as a short intravenous infusion and continued orally over six days . After coDiagnostiX planning (Figs. 9 &10), the osteosynthesis retaining screws were re- moved after four months and the implants placed. Tooth 43, which had been destroyed by caries, was removed on the right. Immediate implantation was performed using a Straumann Bone Level implant (Ø 4.8 mm, L 12 mm). StraumannBoneLevelimplants(Ø4.1mm,L10mm) were inserted in positions 44 and 46 (Fig. 11). On the left, three Straumann Bone Level implants wereplaced(inposition33,aStraumannBoneLevel implantmadeofRoxolid;Ø3.3mm,L14mm;inpo- sitions 34 and 35, Straumann Bone Level implants; Ø 4.1 mm, L 10 mm; Figs. 12–15).
