Full description

To compare short-term performance and safety of the Straumann PURE 2-piece Ceramic Implant with Straumann Bone Level Implant using a fully digital workflow. Post-market, multi-centre, prospective, open, randomized-controlled, non-inferiority clinical study investigating patients in need of dental implant therapy for single-tooth gap rehabilitation. The follow up time is1 year after final crown restoration.

Inclusion criteria

Patients must have voluntarily signed the Informed Consent Form before any study related procedures are performed, are willing and able to attend scheduled follow-up visits and agree that the pseudonymized data will be collected, analysed, and published.
Patients must be males or females who are a minimum of 18 years of age.
Patients, who are in need of a single tooth replacement with a dental implant in the premolar-to-premolar area in the mandible or maxilla (excluding lower incisors).
Presence of natural teeth on both sides of the study implant position and opposing dentition (single tooth gap).
Patients with healed extraction sockets, which means that at implant surgery:
- Soft tissue coverage of the socket is complete; and
- Alveolar bone is reconsolidated (around 16 weeks after tooth extraction).

Exclusion criteria

Patients with inadequate bone volume where major bone augmentation would be required at implant location.
Inadequate anatomic situation that would prevent prosthetic-driven planning based on CBCT.
Presence of implants neighbouring the study implant.
Patients with inadequate oral hygiene (FMPS ≥ 20%).
Patients with local root remnants.
Patients with inadequate wound healing capacity.
Patients with incomplete maxillary and mandibular growth.
Patients with medical contraindications to implant surgery (uncontrolled bleeding disorders, psychoses, prolonged therapy-resistant functional disorders, xerostomia, weakened immune system, illnesses requiring periodic use of steroids or uncontrollable endocrine disorders.
Patients with drug or alcohol abuse.
Patients with allergies or hypersensitivity to zirconium oxide (ZrO2), yttrium oxide (Y2O3), hafnium dioxide (HfO2), aluminium oxide (Al2O3), and titanium (Grade 4).
Patients with medical contraindications to implant surgery (uncontrolled bleeding disorders, psychoses, prolonged therapy-resistant functional disorders, xerostomia, weakened immune system, illnesses requiring periodic use of steroids or uncontrollable endocrine disorders).
Patients with 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.
Pregnancy or intention to become pregnant at any point during the study duration.

Furthermore, patients with uncontrolled periodontitis and less than 3 mm of keratinized mucosa at the day of surgery will be excluded from the study. Controlled periodontitis is defined as treated periodontitis with two or less pockets that are < 4 mm in depth or the existence of ≤ 20% bleeding on probing.

If the planned implant position is the second premolar, the adjacent molar must be present. Shortened arches with missing molars are not eligible in such a case.
