I had lost too much upper bone for implants. I was offered to have three broken roots pulled for an ordinary upper denture. Thank God I went to Dr Walker first! I learned even broken roots may be renovated, securing permanent locaters for a snap-in denture. No denture adhesive. What he gave me was a work of art that looks and feels like my own teeth. What I saved over implants was phenomenal. What I learned was inestimable. Difficult cases, please talk to Dr Walker FIRST! I am so glad I did.
