Rehabilitation of a single tooth in the aesthetic zone by means of one implant with immediate restoration Oral Health
Conditions
Interventions
The missing tooth is replaced with a Straumann BLX in the aesthetic zone. After the healing period, a screw-retained zirconia-based single crown is realized and delivered to the patient. Patients are

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Radiographic marginal bone loss (MBL) assessed using standardized intraoral digital periapical radiographs with the parallel technique by means of customized periapical radiograph holder (Rinn, DentsplySirona, York, PA, USA) at definitive prosthesis placement (baseline) and after 1 year 2. Implant and prosthetic success measured at 1-year follow-up visit: 2.1. Implant success defined in case of probing depth (PD) <5 mm together with absence of bleeding or suppuration on probing, and a radiographic marginal bone level (MBL) <1.5 mm 2.2. Prosthetic success defined as the presence of the definitive prosthesis with patient satisfaction and without complications including and not limited to fracture/chipping, screw loosening, and prosthesis mobility 3. Implant survival rates defined as the presence of the implant without pain or mobility at any follow-up examination | — |
Secondary
| Measure | Time frame |

| Effects of implant location, flap design and implant timing on insertion torque and implant stability quotient (ISQ) values, recorded by Osstell implant stability recording at implant placement | — |
