CeraRoot vs. metal implants

The existence of a microgap in two-piece metal implant system has been well documented in the literature. This microgap is in microns size and several in-vitro studies tested the microleakage through the microgap and its effect on hard and soft tissues. It was proven that this gap acts as a reservoir for bacteria which induced peri-implant tissue inflammatory reactions.

Microgap is defined as the microscopic space that exists between the implant body and abutment. This gap is generally measured in microns meters and is located at the junction between the metal implant and implant abutment. The microgap may act as a reservoir for bacteria, which can lead to release of bacterial byproducts and induction of an inflammatory reaction at both soft and hard tissue level. The main mechanism proposed for microgap-related crestal bone loss is the role of this space as a trap for bacteria and thus, as a putative etiological factor for inflammatory reaction in the peri- implant soft tissues. The establishment of inflammatory cell infiltrates at the implant- abutment junction, even around implant with meticulous plaque control and clinically healthy soft tissue, has recently been shown histologically by Ericson et al. In another study, the implant-abutment interface at the alveolar bone crest was associated with persistent peri-implant inflammation. This second study was conducted to compare the distribution and amount of inflammatory cells adjacent to implant with a supra-crestal, crestal or sub-crestal implant-abutment interface. Polymorphonuclear leukocytes or neutrophils accumulated at the greatest levels near or immediately coronal to the interface. However, peri-implant neutrophils increased progressively as the implant-abutment interface depth increased. Thus, the inflammatory cell accumulation below the original bone crest was significantly correlated with bone loss. In a clinical study, Quirynen et al, suggested that the microorganisms detected from the inside of the implant three months after abutment connection may be the result of leakage at the implant-abutment interface or contamination during abutment connection.

The picture above shows how the CeraRoot implant maintains good gingival health.

The titanium implant, however, due to its two-piece design, does not provide good conditions

for the gum to be 100% healthy.

How often do we see fractures of implants? 

The picture below shows a little screw that is placed on the day of the surgery inside the titanium implant to avoid liquids and food particles to build up inside the threaded connection of the titanium implants. This shows that blood can accumulate inside the implant and bacteria may colonize this area days or weeks after the surgery. This is not possible to happen when the dental implant used is made of one-piece such as CeraRoot, with no gaps and connections where bacteria and blood can accumulate. The picture was taken with a microscope and posted on Instragram by Dr. Liwaa Torbey.


Below, you can find the picture of a conventional titanium dental implant that had failed from the patient’s mouth due to unknown reasons with bone graft particles still adhered to it. The white arrows around the implant are pointing areas that have suffered oxidation / corrosion.  This corrosion does not occur with ceramic implants, because the surface of the implant is very stable and does not change overtime specially when in contact with food/liquids that are present in the oral cavity.

  1. This information and pictures is enormously helpful. I need 5 implants. I am 66. I don’t have a lot of money. My gums are healthy but I have a lot of missing teeth due to unnecessary extractions when I was a teen. The few caused problems with more teeth over the years. My front teeth are good, not beautiful but acceptable. I want to get rid of partials etc. I have not found a dentist I trust. The ones I do, I can’t afford, Please tell me how I can get the Ceraroot implants, where, and the cost.

  2. CeraRoot is a godsend for patients like me who are allergic to all metals (except Gold). I have worked with T implants in the past.In my experience I could always tell the differance between a natural tooth or even a ceramic crown from a TI implant. The metal showed thru the gingiva and the “butt joint” between the base of the crown and the top of the TI always had an obvious “gap”. I think that TI oxidation has a lot of physical effects on patients that hasn’t even been documented yet. (Good subject for a OS or Perio grad student ). I also noticed that the opperator who placed the implant has ALOT to do with the success and esthetics of it. I really wish the CDA or ADA would require a certification before every Tom Dick and Harry makes claims to be an ” Implant Specialist”. It reminds me of the DDS movement to jump into Ortho.Being an Ortho Specialist myself there is a reason why the Ortho program is an additional 3 to 4 years. Dear Peers : do not do implants unless you know what the hell you are doing. I rest my case.
