Inclusion criteria
Inclusion criteria: General Inclusion criteria: - Age of study participants: 18-80 years at inclusion - Signed informed consent - Patient in good medical and psychological health with availability for follow-up. - Adequate oral hygiene And the following local Inclusion Criteria: - Patient with single-tooth implant indication: missing a single mandibular or maxillary tooth. And in need of implant-supported, single restoration. - Sufficient bone and keratinized soft tissue availability for implant placement without regenerative therapy: Presence of adequate of vertical and horizontal native bone in the recipient sites to allow implant placement without the need for bone regeneration techniques: healed sites with vertically and horizontally at least 1 mm of bone around the implant and thus no need for augmentation; minimum bone height: = 7 mm and minimum bone width: = 5.0 mm. It is also required to present sufficient keratinized gingival tissue (at least 2 mm) and to meet appropriate standards of oral hygiene (plaque and gingival indices <15%), since the study aims to evaluate healthy peri-implant mucosa, and no signs of peri-implant tissue disease are therefore allowable. - Presence of both adjacent teeth. - antagonistic jaw with antagonistic natural dentition or tooth/implant borne rehabilitation which can be used to create a stable occlusal fit with the new restoration.
