Good general health(The patient has no systemic disease that can affect clinical outcomes)
Periodontal health(Plaque index and BOP should be below 20% before prosthetic treatment)
There is a good keratinized gum around the abutment tooth (gingival biotype is thick).
It should not have obvious signs and symptoms of bruxism or clenching
abutment teeth need reconstruction
Non-living abutment teeth that have a positive long-term prognosis based on clinical evaluations and radiology
Non-living abutment teeth that have a positive long-term prognosis based on clinical evaluations and radiology
The teeth have sufficient preparation length to ensure retention and resistance shapes
