Abstract

The aim of this study is to present 18 months follow-up results of porous tantalum trabecular metal-enhanced titanium dental implant (PTTM) in implant supported prosthesis in post-oncological patients. A total of 25 PTTM implants were placed in each jaw of 6 patients that met specific inclusion and exclusion criteria. Resonance Frequency Analysis (RFA) was conducted and Implant stability was recorded in ISQ values (Osstell ISQ, Osstell AB, Goteborg, Sweden) at implant placement and after 2,4,6,12 and 18 months of functional loading. Mean bone loss was also evaluated at the same interval of time on each periapical radiographs, bone levels were calculated by measuring the distance from the implant shoulder to the first bone to implant contact. Cumulative implant survival rate is 100% (n=25/25) to date and mean ISQ values recorded were: 72.14±5.61 (range= 50-81) at surgery, 64.39±8.12 (range=44-74) after 2 months, 74.26±7.14 (range=44-74) after 4 months, 76.84±7.65 (range=60-83) after 6 months, 78.13±4.14 (range=64-84) after 12 months and 80.22±6.23 (range=68-89) after 18 months of functional loading. Mean crestal marginal bone loss was 0.19±0.25 mm after 2 months of functional loading on periapical radiographs, 0.22±0.4 mm at 4 months, 0.3±0.46 mm at 6 months, 0.57±0.62 at 1 year and 0.64±0.60 mm after 18 months. The results of this study, even if limited by the number of implants placed indicate that PTTM dental implants have a clinical efficacy in prosthetic rehabilitation of post-oncological patients, due to trabecular structure of the porous Ta metal that increases bone-implant connection values.
