In 2009, the follow-up of this unconven-tional protocol was 2 to 3.5 years; this article documents now the long-term 5- to 8-year follow-up of 3 patients and 5 im-plants. Over this period of time, implant stability was maintained without complications. This unconventional protocol opens intriguing possibilities; however, more patients with long-term follow-up are warranted before endorsing it in routine appli-cation. Nonetheless, it might suggest that there is still room to revisit one of the leading concepts in dental implantology.<\/jats:p>","DOI":"10.2174\/1874210601509010015","type":"journal-article","created":{"date-parts":[[2015,2,4]],"date-time":"2015-02-04T04:34:17Z","timestamp":1423024457000},"page":"15-20","update-policy":"https:\/\/doi.org\/10.2174\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Unconventional Implant Placement IV.
