Beskrivelse
Inclusion Criteria:
Subjects must require extraction and replacement of a tooth in the maxillary or mandibular anterior or premolar region with an implant reconstruction.
- ≥22 years of age
- Patient in a good general health
- Adequate bone quality and quantity for one-stage implant placement
- Patient with physical status PS1 and PS2 (according to Physical Status Classification System of the American Society of Anesthesiologists; Attachment 5)
- Adequate bone height of at least 1mm longer than the length of the study implant
- Capable of providing written informed consent.
- Obtained informed consent from the patient and committed to the study and the required follow-up visits.
Exclusion Criteria:
Patients with a high lip line / smile line
- Thin mucosal biotype
- Anatomically not sufficient bone volume or height at implant site to achieve primary stability of the implant
- Pronounced esthetic expectations
- Lack of keratinized mucosa at implant site (< 2mm oral and buccal)

- Patients with inadequate oral hygiene or persistent intraoral infection
- Smokers exceeding 10 cigarettes / day, or equivalent; patients chewing tobacco
- Severe bruxism or clenching habits
- Presence a systemic disease or allergy (e.g. conditions requiring chronic routine prophylactic use of antibiotics or prolonged use of steroids, history of rheumatic heart disease, bacterial endocarditis, cardiac vascular anomalies, prosthetic joint replacements, etc.)
- Presence or history of receiving intravenous or subcutaneous antiresorptive agents, such as bisphosphonates
- Presence of mucosal diseases (e.g. erosive lichen planus) in the localized area around the study implant
- Patients with history of renal failure, bleeding disorders, metabolic bone disorder, uncontrolled endocrine disorders, HIV infection, leucocyte dysfunction and deficiencies, neoplastic disease requiring the use of radiation or chemotherapy, etc.
- Patients with alcohol or drug abuse
- Participation in any other clinical trial (drug or device) less that 30 days before implant insertion
