Rescuing teeth 2022- Gordon Christensen, DDS PhD

# data[].attributes.body
Discussed several materials
Crack tooth syndrome

if marginal ridge is removed 3x more likely, repair with MTA and follow up

Cementing

Rely X Luting (PFM, zirconia, FPD, full metal, some lithium)

Fiber post- used now 90% compared to cast metal but more likely for post to break rather than tooth

Bruxers and grinders need a post, if tooth has no adjacent support post is needed, if canine has a canine rise

He loves to use Glutaraldehyde (cementing zirconia crowns, crack, pulp exposure, before etching)
