Warping of Biohorizon Secure OD Implant Housing and Inserts?
Has anyone experienced warping of the BioHorizon OD Secure nylon inserts in overdenture cases during insertion of either maxillary or mandibular retained overdentures especially if the abutments are slightly less than parallel? This is usually not a problem with Locator inserts, as one can select extended range inserts and the insert diameters are wider offering a little more leeway. However, the BioHorizon OD Secure inserts are significantly smaller in diameter and I have noticed they require extreme parallelism for path of insertion for optimal fit and retention especially if only using two. Any ideas?

As I have mentioned in previous posts, I use locator retained dentures frequently. I think they are excellent.
However while I almost never have a problem with the plastic inserts (except they become less retentive over 6-24 months – but they are easily replaced with new ones), I have found inexplicably that the locators themselves wear in many cases (especially if they are a bruxer). This is despite the fact that almost all cases have surgical guide placed parallel implants.
Therefore the problems my patients have are similar to yours except the wear is on the reverse component.
Unfortunately in such cases I have found the easiest (and only way in almost all cases of extreme wear) is to replace the locator with a ball component and use the appropriate metal clip as the retention device in the denture. Thankfully these wear very well which is a blessing because the old rubber “O” ring retainers used to wear easily and quickly (necessitating frequent replacement – especially in non parallel situations).

Due to this small size the OD secure does not allow much offset. That is why many clinicians prefer the plain old locator. to correct your problem use the X-tend OD secure housings rather than the standard 'purple' housings

I have been using o-rings for over thirty years. BUT, they are always a part of the casting of the connecting bar . If they are made parallel by quality labs such as B.I.T and Root Dental the problems have been almost non-existent. In the few cases that I have tried to use attachments such as locators the problems have been an absolute continuing nuisance. As much as I like and can speak for Biohorizon products, I would think that the same problems would occur with any direct implant to prosthesis component. O-rings are certainly retentive elements but also stress relievers. The multiple force factors placed on the rings are going to wear them out on a regular basis and then the implants themselves are certainly in jeopardy.

Regardless of the implant system used, it is not uncommon that parts wear out and have to be replaced......however, there are situations where the where and tear on the implant body can destroy the walls of the implant internal hex implant, and necessitate a difficult removal of the well integrated implant...so if the accessory parts are damaged, it is a simple matter to replace them.
