Treatment protocols were randomised using a 2\u00d72 factorial design combining different surgical (flapped vs. flapless) and loading (immediate vs. delayed) protocols. MP was assessed using a two\u2010colour mixing ability test and a colorimetric analysis to measure the level of colour mixing (Variance of Hue\u2013VoH). Maximum voluntary bite force (MBF) was measured by a digital gnathodynamometer in the posterior and anterior regions. Sex, age, surgical and loading protocols and ridge morphology were tested as independent variables. MP and MBF tests were performed at baseline (pre\u2010treatment) and the 3\u2010, 6\u2010 and 12\u2010month after implant loading.
