    The Astra Tech 3.0 mm 2 piece implant can be placed and restored in a 5 mm or greater bone space for a mandibular incisor or maxillary lateral incisor site (minimum 5 mm mesio-distal \[side to side\] bone width and 5mm bucco-lingual \[front to back\] bone width) without exhibiting recession of the soft tissue (gingival margin or the interproximal papillae).

    every 12 months for 3 years

  • A minimum of premolar occlusion is required. A minimum mesio-distal and buccal-lingual distance of 5mm is required

You may not qualify if:

  • Rampant caries or unstable periodontal disease of the remaining dentition.
  • Any systemic or local disease or condition that may compromise post-operative healing.
  • Long-term use of systemic corticosteroids or other medications that may compromise post-operative healing.
