Patient records up to 12 years post-treatment were independently reviewed after a single clinician surgically placed titanium long-arm (\"Tatum\") ramus frame implants and immediately loaded them with a mandibular overdenture. A total of 11 ramus frames were removed at 19 to 109 months post-treatment, mostly due to supramucosal bar fracture (&lt;i&gt;N&lt;\/i&gt; &amp;#61; 6) or mobility (&lt;i&gt;N&lt;\/i&gt; &amp;#61; 3). Kaplan-Meier product-limit analysis revealed the post-treatment survival probability for functional ramus frame implants to be 99.3&amp;#37; at 2 years (266 patients), 98.9&amp;#37; at 3 years (223 patients), 97.9&amp;#37; at 4 years (198 patients), 96.9&amp;#37; at 5 years (160 patients), 96.9&amp;#37; at 6 years (123 patients), 95.0&amp;#37; at 7 years (86 patients), 95.0&amp;#37; at 8 years (67 patients), 93.3&amp;#37; at 9 years (43 patients), and 91.1&amp;#37; at 10 years (25 patients). No statistically significant differences in functional ramus frame implant survival were found relative to patient gender, smoking, presence of natural maxillary teeth, or compliance with semi-annual maintenance care. Fracture of endosseous anterior feet\/posterior arms was the most frequent implant-related complication on 29 implants, which were left in place, repaired, or replaced &lt;i&gt;in situ&lt;\/i&gt; without implant removal. At 5 years, the ramus frame implant functional survival probability without any implant-related biological or mechanical complication was 88.9&amp;#37;. Ramus frame dental implants, immediately loaded with a fully implant-borne mandibular overdenture, exhibited a high degree of long-term functional survival and safety in severely atrophic edentulous human mandibles.\n<\/p>","DOI":"10.1615\/jlongtermeffmedimplants.2023048783","type":"journal-article","created":{"date-parts":[[2023,11,3]],"date-time":"2023-11-03T21:13:06Z","timestamp":1699045986000},"page":"27-36","source":"Crossref","is-referenced-by-count":0,"title":["Ramus Frame Dental Implant Functional Survival and Safety in Severely Atrophic Edentulous Human Mandibles"],"prefix":"10.1615","volume":"34","author":[{"suffix":"Jr.","given":"O.
