Immediate Implant Placement in Posterior Sockets With Periapical Infection and Bone Defects: Three Case Reports
Immediate implant placement is considered a well-accepted procedure due to its advantages and predictable survival rates. However, data on immediate implantation in posterior sockets with infection and bone defects are limited. The purpose of this clinical report was to describe 3 cases of hopeless posterior teeth with periapical infection and relatively large destruction that were successfully treated with immediate implant placement. The mean follow-up time was 22 months. On the basis of correct clinical decision and treatment procedure, immediate implant placement may be a reliable treatment option for compromised posterior sockets.
(a) Preoperative cone-beam computerized tomography (CBCT) image of the retained lower left second deciduous molar. (b) Implant placement and a vertical bone defect of 5 mm around the mesial-buccal surface of the implant. (c) Guided bone regeneration procedure at the defection. (d) Cross-sectional CBCT view at 6 months after surgery. (e) Intraoral view of the final prosthetic restoration.
(a) Preoperative cone-beam computerized tomography (CBCT) images of tooth No. 3 and 5. (b) A U-shaped bone defect on the buccal surface that affects more than 60% of the implant surface at the site of No. 5. (c) Guided bone regeneration procedure. (d) Intraoral view of the cement-retained zirconia single crown. (e) CBCT images at the 24-month follow-up visit after the final restoration.
(a) Preoperative cone-beam computerized tomography (CBCT) image of the maxillary right second premolar. (b) Extraction socket and the apical fenestration. (c) Implant placement and bone grafting in the marginal gap and the apical defect. (d) Intraoral view of the screw-retained zirconia single crown. (e) CBCT image at the 36-month follow-up visit after the final restoration.
