Chronic periodontitis is a periodontal disease characterized by bone loss, which can complicate the implant pro- cedure. In this case report, socket preservation procedure was carried out by applicating a bone graft material to restore alveolar ridge dimensions to prepare for the dental implant placement. A 43-year-old female patient came with complaints of mobility and pain on her lower right posterior tooth when it was used to eat. Clinical examination revealed that the mandibular right first premolar has a 03 mobility, with a periodontal pocket depth of 7 mm. On ra- diographic examination, vertical bone loss reaching the apex of the tooth was found. The patient wanted an implant for her tooth replacement. To resolve this case, the mandibular right first premolar was extracted due to it’s poor prognosis. After tooth extraction, curettage was performed to remove a granuloma inside the socket thoroughly. The bone socket should be openly exposed and free of soft tissues. A bone graft material was applied to the socket and covered with a collagen membrane and then sutured with a horizontal mattress suture. Because the patient did not want to be toothless, the extracted tooth was cut on its cervical line until only the crown remains, and then attached to its adjacent teeth using a flowable composite. The implant was then placed 3 months after the procedure above. The socket preservation procedure is an important procedure to prepare the abutment tissues for implant placement.
