| -Implant survival. The survival rate of the implant will be assessed one year after placement of the definitive restoration. In this study an implant failure is defined as each implant that was removed due to implant mobility as a consequence of loss of osseo-integration. -Probing depth. Probing of the implant and the adjacent teeth is performed at four sites sites (mesial, distal, buccal, lingual/palatinal). The probing depth will be measured pre-operative, one month and one year after placement of the definitive restoration. Probing of the implant is part of normal check-up after implant placement. -Modified Plaque-index and Modified Bleeding-Index, Gingiva index. These parameters will be evaluated pre-operative, one month and one year after placement of the definitive restoration. The adjacent teeth will be counted as well in the assessments. During probing of the implant and the adjacent teeth, the indices as mentioned above can be assessed. Probing of the implant is part of normal check-up after implant placement. Probing of teeth is part of standard dental check-up. -Patient satisfaction. Patients will be asked to complete a questionnaire measuring their satisfaction with the aesthetic and functional outcome of the treatment one month after definitive restoration. Furthermore, discomfort related to implant surgery or associated with the restorative procedure will be assessed one month after definitive restoration. | — |
