Description of the oral functional capacity (OFC) consisting of four resilience capacity levels (RCL 1–RCL 4) and three parameters (therapeutic capability, oral hygiene ability, self-responsibility). The parameter with the lowest value is used to classify the patients into one of the RCLs [19]

Resilience capacity level (RCL)	Therapeutic capability	Oral hygiene ability	Self-responsibility
RCL 1 normal	Normal	Normal	Normal
RCL 2 slightly reduced	Slightly reduced	Slightly reduced
RCL 3 greatly reduced	Greatly reduced	Greatly reduced	Reduced
RCL 4 no resilience	None	None	None
