All participants were rehabilitated according to immediate implant placement using CP grade 4 titanium implants with roughened surfaces and a 12\u00b0\u2010angled platform. Provisional implant crowns were connected within 4 hours of implant placement and loaded according to progressive loading protocol. At 8 weeks (baseline), definitive screw\u2010retained crowns fabricated using densely sintered zirconia abutments with the veneering porcelain were delivered. Participants were followed up to 5 years and 16 participants with 17 single implant crowns attended Year 5 recall. Data collection included changes in marginal bone levels (MBLs), mid\u2010buccal mucosal levels (MBMLs), implant stability quotient (ISQ) values, and any prosthodontic maintenance issues.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean changes in MBLs at each recall was bone fill of 0.5\u2009\u00b1\u20091.18\u2009mm (surgery\u2014baseline), increase of 0.1\u2009\u00b1\u20090.57\u2009mm (baseline\u2014Year 1), and marginal bone loss of 0.1\u2009\u00b1\u20090.25\u2009mm (Years 1\u20105). A minimal change occurred with the MBMLs during the observation period. The mean ISQ value at each time point increased from 65.1 (implant placement), to 67.4 (baseline) and 69.9 (Years 1 and 5).
