5. Adequate oral hygiene to allow for implant therapy consistent with standards of care.
6. Adequate bone volume to accommodate the planned endosseous dental implant placement according to immediate placement protocols utilizing Straumann Bone Level implants RC (Regular Crossfit) 4.1mm or Bone Level Implant NC (Narrow Crossfit) 3.3 mm at 8, 10,12 or 14mm in length.
7. One tooth in the anterior maxilla (first pre-molar to first pre-molar) requiring extraction resulting in a single- tooth gap planned to be restored with a dental implant as determined by the patient's dental provider.
8. The site to be treated is surrounded by two natural teeth.
9. Except the site to be treated, none of the maxillary incisors, canines and first pre-molars display marginal soft tissue recession.
10. Following extraction, intact extraction socket bony walls are present.
11. Primary stability of implant consistent with standards of care is achieved at the time of implant placement.
12. Patient must be able to pay for fees related to the surgical implant placement related to extraction, grafting of the implant site, and half of the cost of the crown at the time of implant placement.

11. Patient is taking medications or having treatments known to have an effect on bone turnover, including: thiazide diuretics, calcitonin, systemic steroids, bisphosphonates, vitamin D (>800 IU/day), estrogen or progesterone therapy.
12. Current steroid treatment: defined as any person who within the last two years has received for two weeks a dose equivalent to 20 mg hydrocortisone.
13. Patient currently undergoing chemotherapy.
14. Patient history of radiation treatment to the head or neck.
