Changing O-Rings Frequently and Need Constant Adjustments: Suggestions?

Mini implants can be successful when used properly. The standard protocol for mini implants in the mandible is four (not two) in the front of the mandible (lower jaw). The most common cause of problems with o-rings deteriorating too soon is the implants having diverging angulations (not parallel), and a denture that fits poorly or has no bone support from the ridge. If the existing bone in your mother's jaw is very thin in that area, mini implants are indicated, but four not two and placed fairly parallel to the path of placement of the denture. Ask about these things the next time she needs the o-rings changed to see if any of them are the reason for her problem. Good luck!Dr. Carlos Boudet

Mini implants overall have high rate of failure and are not as stable as conventional implants. The reasons for the problems you mentioned maybe poor fit of denture, poor adjustment of the bite, and poor fit of the O-ring in the housing of the denture. I have seen many complaints by patients with mini implants and frequent problems as such. You might consider getting two conventional abutments and a good fitting overdenture. This type of system works really well and rarely requires adjustments.Dr. H Ryan Kazemi

I just had the four O rings replaced in my lower mini implant. Now the far left implant is painful when I bite down on it. Could it be improper O ring placement or something else..thank you
