case_images: The implant was torqued in 35 N/cm, and a healing abutment was placed (Figures 7-9).
case_images: A 4.7/11 mm endosseous implant was placed at site #3 with the use of osteotome sinus floor elevation technique.

case_images: The implant was torqued in 35 N/cm, and a healing abutment was placed (Figures 7-9).
case_images: A periapical radiograph was taken after the implant placement. Bone condensation is noted apical to implant #3 due to the use of the osteotome sinus floor elevation technique. Mesial of #2, a deep unrestorable decay was observed.

case_images: The implant was referred to the predoctoral clinic for final restoration with cement-retained porcelain fused to metal (PFM) crown (Figure 10).
case_images: The same protocol of extraction, ridge preservation and subsequent implant placement, was followed successfully for site #2. The implant at site #3 did not show any signs of infection or inflammation, radiographically nor clinically.

case_images: The same surgical and restorative approach was uneventfully followed for site #2, as well (Figure 11). The patient was given an occlusal stabilization splint and was placed on a 6-month maintenance protocol in 2014.
case_images: The patient presented at the day of surgical debridement of site #3 with a nondraining fistula at the same site where the fistula was noted before the extraction of #3. The picture is taken after the intrasulcular incisions were performed, with the use of a 15c blade.
