Abstract

When the first dental implants were developed in 1977, implants were placed 6‒8 months after extraction. The long healing time involves absorption of the extraction socket alveolar bone and a prolonged treatment period. To solve this problem, an “immediate implant” was studied, which is placed immediately after tooth extraction. Along with the timing of implant placement, studies on sinus lift were also conducted to overcome the lack of vertical bone height due to the presence of sinus and resorption of alveolar bone in implant placement in the maxillary posterior area. In this case, extraction, sinus lift, and implant placement were performed simultaneously with a crestal approach through the extraction socket in a patient with insufficient vertical bone height for implant placement. As a result, the treatment period of 3‒4 months was shortened, and the number of surgeries was reduced. The implant has shown satisfactory results in both bone and tissue during a 4-year follow-up.
