What is the truly problem with Ti PFM?

[PinAn]

Hi guys, I read some paper at Internet about dental porcelain boding with metal
If just with Co-Cr and Ni-Cr the bonding strength value is around 26~30Mpa
And if the porcelain with Grade5Ti or CP Ti
The value is 26Mpa and if with GC the value will up to 30~35Mpa
Looks like the bonding strength wasn't the main problem with Ti PFM
So what is the truly problem you guys found with Ti PFM?

Thanks

I've done a few hundred units over the past 6 years - never had an issue. I think most of the perceptions regarding Ti stem from back when people were casting it...

Hi RJS thanks for replying,
May I ask you your manufacturing process and which porcelain you are using?

Dark oxide layer, to many layers of opaque to cover, metal creep, technique sensitivity. CoCr and NiCr are just easier for the average tech to use. If you have the ability to mill Ti PFM why aren't you just doing Zirconia?

I was milling my own, but now I have Axis mill them. We have used Dentauram's Tri-Ceram, and simply follow the directions...
