The Success of Dental Implant Placed in Ridge with Inadequate Bone Width and Exposed Screw Threads—A CBCT Case Report with 8 Years Follow Up

Cone beam computed tomography (CBCT) is an advanced technique helpful in detecting bone formation in the deficient ridges after grafting and implant placement without the need for histological evidence. A healthy male patient with a missing tooth in the maxillary premolar region visited the dental hospital for the implantation of the tooth. Initial CBCT examination revealed a horizontal ridge defect in the mid-buccal region. The implant was placed along with grafting in the exposed thread region followed by GTR membrane placement and the area was allowed to heal for 6 months. CBCT was advised immediately after implant placement. The patient reported after 8 years, the soft tissue was perfect with no signs of inflammation and the prosthesis was good functionally and esthetically, a CBCT was advised which helped to detected adequate bone formation and successfully osseointegrated implant. Proper grafting and regular monitoring and follow-up can result in the success of implants in deficient grafted ridges even after 8 years with CBCT helpful to detect bone formation.
