Lost an Upper Incisor: Should I Get Implants?

Ila asks:

My 60 year old mother lost one of her front upper incisors in an accident. Her teeth generally are not in good shape with two bridges in the lower jaw. However, she is able to eat all kinds of food comfortably and has no complaints about the lost tooth apart from the cosmetic part.

Nevertheless, an implant was suggested and we did an OPG. The Report says: "Mild attrition / wear of unrestored teeth and generalized moderate periodontal bone loss are noted. Advanced distal interdental bone loss is noted with 42. Partial bone effacement is noted in the furcation region of the 26 & 27."

Does this mean she will invite needless trouble if she goes ahead with implants? Is it safe to undergo implants with this type of bone density, especially considering that functionally it seems like my mother can do without the implant? Thanks for your help.
