A difficult case due to severe bone resorption on #10. The extraction was done cleanly and waited 4 months for bone to regenerate. Surprised to find buccal side of ridge completely gone. Very thin so had to place 3.5 diameter. Also the bone on buccal disappears as it goes apically. So had to place at a severe angle. Long story short we had to fab a custom ucla abut cast. with PFZ’s. I was pleased with final restoration.
