Trial Title: Controlled Pilot Study to Assess Soft Tissue Reaction at the Crestal Part of a Dental Implant With ESTA Surface

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: SINGLE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* Subjects must have voluntarily signed the informed consent form before any study related action~* Males and females must be at least 18 years of age and not more than 80 years old.~* Partially edentulous in posterior (position 3-7) maxilla or mandible with implants planned for single crowns in an area with a healed extraction socket.~* Adequate bone quality and quantity at the implant site to permit the insertion of a Straumann Soft Tissue Level implant of 4.1mm diameter without augmentation (at least 1mm bone buccally and lingually/palatal)~Exclusion Criteria:~* Oral surgery contraindicated according to the judgement of the investigator (should be explained in the CRF)~* Local inflammation, including untreated periodontitis~* Patients with inadequate oral hygiene or unmotivated for adequate home care. Full mouth plaque index \> 25% at time of surgery~* Presence of conditions requiring chronic routine prophylactic use of antibiotics (e.g., history of rheumatic heart disease, bacterial endocarditis, cardiac valvular anomalies, prosthetic joint replacements)~* Major systemic diseases~* Medical conditions requiring prolonged use of steroids~* Current pregnancy or breastfeeding women~* Physical handicaps that would interfere with the ability to perform adequate oral hygiene~* Use of any investigational drug or device within the 90 day period immediately prior to implant surgery on study day 0~* Alcoholism or chronically drug abuse~* Smokers; more than 10 cigarettes per day~* Immuno-compromised patients~* Conditions or circumstances, in the opinion of the investigator, which would prevent completion of study participation or interfere with analysis of study results, such as history of non-compliance, or unreliability.~Secondary Exclusion Criteria:~* GBR procedures at or adjacent to the planned study site~* Lack of primary stability of the dental implant at site of interest (e.g., rotational movement of the implant at a minimum of 15 Ncm torque at connection of the healing abutment, or tactile mobility)

Study Arms:
- Standard Plus ESTA STL Roxolid implant (Type: EXPERIMENTAL): This arm will receive the Straumann Soft Tissue Level Standard Plus Implant Ø 4.1 mm Regular Neck, SLActive® Roxolid, with a modified surface of the neck (ESTA).
- Standard Plus STL implant (Type: ACTIVE_COMPARATOR): This arm will receive the Straumann Soft Tissue Level Standard Plus Implant Ø4.1mm Regular Neck,SLActive® Titanium grade IV, with a machined surface of the neck.
