Primary	success rates of the implants	Success is graded in three qualities, depending on the extent and results of performed examinations.; Grade 1.; Absence of mobility is checked by individual stability testing of the unattached implant.; Radiographic evaluation of each implant reveals not more than 1.0 mm of marginal bone loss during the first year of loading, followed by not more than 0.2 mm resorption per year.; Severe soft tissue infections, persistent pain, paresthesia, discomfort, etc.; Grade 2.; Radiographic evaluation; Severe soft tissue infections, persistent pain, paresthesia, discomfort, etc, are absent.; Grade 3.; Radiographic evaluation. Peri-implant pathosis, such as a peri-implant radiolucency is absent.; Severe soft tissue infections, persistent pain, paresthesia, discomfort, etc, are absent.	1 year

Secondary	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

Secondary	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

Secondary	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
