520			_aIt was clearly evident in the postoperative CBCTs that bone did not form on the very apical part of the implants, except for implant No.1, this was very similar to the others{u2019} findings when osteotome-assisted closed sinus lifting was used.65,68 This can be attributed to the collapse of the Schneiderian membrane around the summit of the implant. Accordingly, insertion of longer implants might prove beneficial as regards the net bone gain around the implants. It can also be argued that simultaneous bone grafting could further support the Schneiderian membrane and positively affect the bone height gain.In cases of narrow ridges where the lateral and medial walls of the sinus were closer to each other, some of the implants that were slightly misaligned did come in contact with either of the sinus walls. When this happened, new bone could not be radiographically detected around the respective implant walls and accordingly no bone height measurement could be recorded. This was the case in implants No.2, 6, 8, 9 and 10. Although no bone density measurements were included in this study because of the fact that CBCT is not a reliable method to measure density, however, it could be noticed that the newly formed bone around the inserted implants in this study were of adequate radiopacity and would have probably become more dense by time. Despite that the introduced technique in this study showed good results in terms of primary stability and predictable new bone formation while using a minimally invasive approach and with minimal costs, longer post-loading follow-up is definitely needed to analyze the long-term success of the implants placed using this technique
