ERA Implants: Easier System for Implant Supported Overdentures?

era.jpgI have been using conventional dental implants for my overdenture cases. I would like to try the ERA Implants (Sterngold) because they are far less expensive and seem easier to use. The system can correct for misangled implants by using an angled housing that can be cemented into the one-piece implant/abutment. Seems to be a pretty simple protocol. Also it has one-piece implant/abutments that are straight and can easily be torqued into implant channels that are straight and do not need correction. Anybody using the ERA implant system? What have your results been?

Editor’s Note:
According to Sterngold:”The ERA Implant consists of a micro ERA prosthetic head on a 2.2 mm diameter self-tapping implant which may be used for immediate stabilization of a complete denture. A wider 3.25 mm diameter self-tapping implant is also available.
The entire micro ERA Implant procedure takes about 90 minutes and the patient leaves the chair with their denture snapped into place.”

  1. I have used the ERA implants for the past 3 years with great success. I like them much better than either the Imtec or IntraLok systems because of the attachment. With ERA you can correct for parallelism and also adjust for strength of the attachment. The surgery is a little more involved, but not much. Give them a try.

  2. I also have used the ERA implants for a few years. I use a number of different implants systems, but the majority of my implant retained overdentures are completed with the ERA system. The attachment is the best. Vertical and hinge movement and is simple to pick up chairside. With the 2.2 and 3.25, you are not depending on Mini only for long term stability. As to the surgery being more complex, I disagree. The surgery is the same as for any implant. If you have enough bone and tissue, can possibly be a punch technique. If you have questions about the bone and do not have a CT scan quided surgery, a flap should be made and the bone vizualized. I believe this is true no matter what implant you are placing. To think that just because it is a Mini, you can always do flapless surgery will eventually get you into trouble.

    The Sterngold ERA system is the best of both worlds. Mini for immediate load and 3.25 for long term delayed load stability. If you lose the 2.2, the patient still has 3 implants to retain the denture.
    Contact Sterngold @ They have a video on their website.

  3. I have used the ERA mini implants and have used other minis with “O” ring heads. I Prefer the ERA mini as the C/I ratio is better, the lower profile of the ERA attachment on the mini allows more acrylic over the attachment allowing a stonger denture. The problem with “O” ring heads is they have to be relatively parallel or you have lateral loading and tension on the implants when the denture is inserted and this can lead to failure of the implants or premature wear of the attachment. The 3.25 diam mini ERA implant does allow angulation correction with an insertable attachment with several degrees of correction. I have used the 3.25 and immediately loaded them into the denture so these can be used in this manner.

    I would direct you to the article “Improving Mandibular Denture Retention
    with Sterngold ERA® Mini-Implants” in the March 2008 issue of Inside Dentistry that discussed the use of these implants.

  4. I have been placing implants for 20 years for tooth replacement and overdenture. During this time I have used many different types of attachments, Dolder Bar, Hader Bar, Ball and O-Ring, etc. While there are protocols for each attachment type I began using predominantly ERA with traditional implants many years ago. I found a completely satisfied patient population. The patients were able to maintain peri-implant health quite easily and retention of the prosthesis has been excellent. The introduction of the ERA implant has the benefits of being a stud attachment with .4mm of vertical resiliency, angle correction, 6 levels of retention, and easy chair side utilization. The FDA has approved the 2.2mm mini for intermediate use however if the immediate loaded implants integrate fully they can be left in place. The 3.25mm is approved as a permanent implant. Dr Thomas reports that the surgical placement is not more more complicated than any other implant system and I would agree totaly with his statement. The implants are placed as a one stage with the unloaded implants relieved under the denture. The other great benefit of the ERA implant is that the patient gets immediate retention at the time of surgery. The known principles of osseointegration apply for the etched ERA implants and the aggressive thread design provides for very good initial stability.

    Sterngold has an excellent education department and knowledgeable sales personel.

  5. HI,

    I am searching for a way to replace the ‘shoeheel’ upper denture design, with the ‘horseshoe’ like a bottom denture.

    Will the ‘implant supported denture’ for an upper denture return my upper palate for use, or is this technique just a firmer way of holding the horseshoe denture? I find myself doing ‘tongue shuffleboard’ especially with bread products, then, loosing appetite while I eat, because, psychologically, my body seems to reject the ‘foreign object’, which, if it was just in the original teeth area, would not happen….also, why is the upper casting for the horseshoe upper denture not ridged on the palate opposite side so the ‘tongue would not so much sense the prosthesis’?

    Ideally, for a patient, the upper or lower denture would ‘snap in place’, require no adhesive, and simply replace the profile of one’s teeth, removable for cleaning, etc.

    Thanks for any information you can send me.

    Sincerely, NAN

  6. although the implant is osseointegrated in the bone but after sometimes due to pull and push force ,the lmplant becomes loose and i saw this event really with 2 patients ater insertion of the over-denture after wearing and using really with another system having the system of this implant and same rule.thanks,professor seham tayel .alexandria univ.egypt. prostodontic department.
