They were randomly assigned to receive either a one\u2010piece (STM) or two\u2010piece (BRA) implant system. Final restoration delivery served as baseline, after which all patients entered a structured maintenance program. Clinical re\u2010evaluations were performed at 1, 5, 10, 12, 15, and 17\u2009years. Biological, technical, radiographic, and esthetic parameters were assessed at each follow\u2010up visit using standardized clinical and radiographic protocols.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Thirty\u2010nine patients with 95 implants, all of whom had completed a 15\u2010 or 17\u2010year follow\u2010up visit, were included in the final analysis (STM: 22 patients\/45 implants; BRA: 17 patients\/50 implants), with a mean follow\u2010up of 16.4\u2009\u00b1\u20091.1\u2009years. The cumulative implant survival rate was 95.0% (STM: 91.8%; BRA: 98.0%). Marginal bone levels at 15\u201317\u2009years were 0.08\u2009\u00b1\u20091.15\u2009mm (STM) and 1.53\u2009\u00b1\u20090.81\u2009mm (BRA). Clinical parameters remained stable in both groups, although BOP was higher in the STM group. Peri\u2010implant mucositis was observed in 49.7% of all implants and peri\u2010implantitis in 13.3%, with higher rates in the STM group. Technical complications occurred in 28 implants (STM: 23; BRA: 5), with the STM group showing a higher complication rate (implant level: 35.4% vs. 5.8%). Esthetic observations included visible crown margins in 62 implants and mucosal shimmering in 54 implants, with no implant fractures reported.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Both implant systems demonstrated favorable long\u2010term outcomes with high survival rates.
