Osteotome-Induced Blood Clot and Subsequent Bone Formation with the Use of Collagen Sponge for Integration of Single Dental Implants into the Atrophied Posterior Maxilla: A Retrospective Follow-Up of 36 Implants after 5 to 13 years

<div>(a) Preoperative CT showing a crestal width of 9.5 mm and a distance of 3 mm from the top of the crest to the lowest point of the maxillary sinus. (b) Periapical radiograph taken immediately after implant insertion. (c) Periapical radiography taken after 9 years of prosthetic loading: note the bone remodeling and the new position of the sinus cortex.</div>
