Positive MELISA Test for Titanium: What Are My Options for Implants? Zirconium?
Anon asks:
I have a history of autoimmune disease, and currently have atopic eczema. I lost a tooth 2 years ago and wanted an implant. Given my medical history, I decided to have a MELISA test and tested positive to nickle and titanium DICHLORIDE but was negative to titanium TRICHLORIDE and zirconia, as well as other metals such as aluminium.
I would therefore like a dental implant that's primarily T. Dichloride/ zirconium in composition, but I hear that the latter cracks and breaks so it may not be ideal. I don't want a bridge as the teeth around the missing tooth are healthy. Any advice??? Many thanks

I have not heard of the zirconium implants that fracture. They have been on the market a short time, though, and with all the studies it appears to be a very good option for implant placement. The cost is more than titanium implants.
Good luck

Zirconium Implants
Hello
There is a significant amount of literature over the past four years available on these implants. If you do a Google search you will find that there are specific pros & cons.
The literature mentions fracture of Zirconium during preparation of the prosthetic part of the implant for the crown. It is a one piece implant, with the intention of eliminating the "micro gap" between implant and abutment. The one piece design makes it less adaptable for placement in areas requiring angulation of the prosthetic part. The anterior maxilla usually requires significant angulation of the prosthetic end of the implant.
Careful planning with models & C.T. scan will determine suitability of a Zirconium implant to suite your needs. Best of Luck.
