| Pink Esthetic Score | The PES is based on seven variables: mesial papilla, distal papilla, soft-tissue level, soft tissue contour, alveolar process deficiency, soft-tissue color and texture. Each variable was assessed with a 2-1-0 score, with 2 being the best and 0 being the poorest score. | 1 year |

| Patient satisfaction - Questions will be scored on 100mm visual analog scales. The patients marked their response on a horizontal line for which the most negative expression corresponded to 0 and the most positive to 100. | Questions: Are you satisfied with the aesthetic outcome of the gums surrounding this implant? Are you satisfied with the function of your implant-supported tooth? Would you undergo the same procedure again? | 1 year |

| Patient satisfaction with single-tooth implant treatment measured with the Oral health impact profile-14 questionnaire | The questionnaire was divided into seven domains, containing two questions each, resulting in a total of 14 questions. The domains were functional limitation physical disability, physical pain, psychological disability, psychological discomfort, social disability and handicap. The overall OHIP-14 score is the mean of the 14 questions. The questions pertained to seven domains and were averaged on a scale of 0-4, with 0 defined as "never" a problem and 4 defined as "very often" a problem. | 1 year |
