- Adequate soft tissue level/contour at the facial aspect of the failing tooth as compared to the surrounding teeth.

- Adequate bone height apical to the alveolus of the failing tooth (x5 mm) to ensure primary implant stability

- Presence of local or systemic disease (i.e. severe osteoporosis, Paget's disease, renal osteodystrophy, immune suppression, corticosteroids treatment in the recent past)

- Cancer therapy including immunosuppression, chemotherapy and radiation.
