Overview
Brief Summary
After atraumatic tooth extraction and the assessment of the feasibility of immediate implant placement, patients will be randomly assigned to one of three treatment concepts:
- Immediate Implant Placement and Immediate Provisionalization
- Alveolar Ridge Preservation. After 4 months of healing an implant will be placed with simultaneous GBR and/or Soft Tissue Augmentation procedures, if needed.
- Spontaneous Healing of the socket. After 4 months of healing, an implant will be placedwith simultaneous GBR and/or Soft Tissue Augmentation procedures, if needed.
In all groups, four months after implant placement, a prosthesis will be delivered. From this experimental period onward, patients will be scheduled for maintenance. Clinical, radiographic and volumetric assessment will be performed by clinicians not involved in the surgery and blind with respect to treatment assignment at 1, 3 and 5 years post loading.
Detailed Description
The overall objective of this study will be to compare the three treatment modalities after tooth extraction (immediate implant placement, alveolar ridge preservation, spontaneous healing) in terms of: * patient-related (morbidity) outcomes during surgical procedure and the first 2 weeks after the surgical procedure * cost-effectiveness ratio (treatment time, number of surgeries, number of appointments and overall appointments time, need for bone and soft tissue augmentation, overall costs) at the time of prosthesis delivery * volumetric bone and soft tissue changes of the site before treatment (prior to tooth extraction), 4 months after tooth extraction, 1, 3 and 5 years after final prosthesis. * clinical, radiographic, aesthetic and patient-related (satisfaction) outcomes at the time of prosthesis delivery and 1, 3 and 5 years after final prosthesis. * Implant Success and Survival at 1, 3 and 5 years after final prosthesis.

Outcomes
Primary Outcomes
Rate of adjunctive bone and soft tissue augmentation procedures need.
Time Frame: during implant placement
Number of participants with the need for adjunctive reconstructive hard tissue procedure during implant placement will be evaluated as a frequency (Yes/No) after a digital prosthetically driven implant placement. The need for soft tissue augmentation during implant placement will be evaluated as a frequency (Yes/No) by a blinded examiner in case of buccal soft tissue thickness \< 2mm assessed at 3mm apical to the full thickness flap margin with a caliber.
Secondary Outcomes
- Peri-Implant Health(1, 3, 5 years post loading)
