Dental Implant Failed
Conditions
Brief summary
Survival and success rates of all-ceramic implant-supported fixed reconstructions fabricated with CAD/CAM technology after at least one year in function. Survival and success rates (clinical, radiologic and esthetic) of all-ceramic implant-supported fixed reconstructions fabricated with CAD/CAM technology after 2 to 10 years in function. Establishment of a database of patients with all-ceramic implant-supported fixed reconstructions fabricated with CAD/CAM technology for future longitudinal retrospective studies.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Survival and success rates of all-ceramic implant-supported fixed reconstructions | 1 year | Number of all-ceramic implant-supported fixed reconstructions fabricated with CAD/CAM technology still in place after at least one year in function. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of patients with biological complications assessed via periapical x-ray | 1 year | A radiological evaluation of the implant crowns will be performed to measure and evaluate the bone crestal changes |
| Number of patients with technical complications | 1 year | A clinical evaluation of the implant crowns will be performed in order to detect any kind of complication, namely chipping, screw loosening or abutment fracture |
| Number of patients with biological complications assessed via clinical examination | 1 year | A clinical evaluation of the implant crowns will be performed in order to detect any kind of biological complication, namely periimplantitis and perimucositis |
| Patient satisfaction as assessed by VAS B | 1 year | Patients assess by patient questionnaire their implant reconstructions, in terms of esthetics by means of a Visual Analog Scale (VAS B), where the parameter will be scored from 1 to 10. |
| Esthetic outcome | 1 year | The esthetic examination included the Pink and White Esthetic Score Assessment (PES/WES) according to Belser et al. 2009 & Furhäuser et al. 2005 on a scale from 0-10 whereas 10 means an optimal outcome. |
| Patient satisfaction as assessed by VAS A | 1 year | Patients assess by patient questionnaire their implant reconstructions, in terms of function by means of a Visual Analog Scale (VAS A), where the parameter will be scored from 1 to 10. |
