The modified Sulcus Bleeding Index (mSBI) (primary outcome) was assessed at baseline (BL) and 6, 12 and 36 months. Secondary outcomes included the assessment of pocket probing depth (PPD), mucosal recession (REC) and clinical attachment level (CAL). Standardized radiographs were taken at time of implant placement, at BL and after 12 and 36 months.<\/p>\n\n\n\n<p>RESULTS: Of the 43 randomized subjects, 38 (19 test and 19 controls) completed the 36-month follow-up. Implant survival rates amounted to 95.5% (test) and 100% (control) (p &gt; .05). At 36 months, 77.6% of test implants and 78.9% of control implants were without any bleeding sites (mSBI = 0) (p &gt; .05). The 36-month success rate was 86.4% in the test and 85.7% in the control group, respectively (p &gt; .05). At 36 months, the mean radiographic bone level change from BL was 0.33 \u00b1 0.69 mm at test implants and 0.12 \u00b1 0.3 mm at control implants (p &gt; .05).<\/p>\n\n\n\n<p>CONCLUSION: Tissue level implants with a hydrophilic mSLA transmucosal neck failed to yield clinical and radiographic benefits compared with implants with a machined neck up to 3 years.<\/p>\n\n\n\n<p><a href=\"https:\/\/doi.org\/10.1111\/jcpe.13249\">https:\/\/doi.org\/10.1111\/jcpe.13249<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/?term=31912523\">https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/?term=31912523<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Prix SSP-GABA de la meilleure publication 2020.
