can orbital implants also cause bone resorption?

[herring]

in the zygomatic/orbital area? similar to chin implants?

 

[beyourself]

Should they? What the fuck, life is a scam.

any foreign object under your skin will apparently :/

all implants cause bone resoprtion but there is only 1 study shows long term follow up with jaw implants, and there is only 2mm bone resorption at worst.

Yeah, life is indeed a scam. Meanwhile chad has Eppley's state-of-the-art implants integrated in his very bone since day 0.

fight for your life. all in all,at the end, we will be counting on scenes that we were happy.
so, instead of being defeatist, get what you can.

Bone resorption is maximum in the chin, not that much in the malar region, as per Eppley.

They gonna make your bones age faster

whatever, by the time i'm an oldcel new tech should be available anyway

can you link the study

I just tried to find that 2015 article, and guess what?
I find 2022 meta-analysis report showing mean 2mm but in some cases more than 4mm, damn.

I'll post the old article when I find.

I'll read it better later, but do you know what is that dark part between the two white layers of the bone
is the medular bone, the non mineral part of the bone?

also, was the resorption on the whole surface under the chin implant?

eppley wrote this article about imprinting:

My question is, how much does the implant advance into the bone? what is inside the bone is not the soft part/bone marrow? and many bones have a cortical layer thickness (the hard outer part of the bone) thinner than 2 mm... can it be bad to have the implant stucked nside the bone?
I wish someone who understood could explain this to me better.

Understanding the Biologic Concept of Bone Imprinting Caused By Facial Implants - Explore Plastic Surgery

imprinting on the bone is an expected biologic reaction to an implant material that is placed as a spacer between the bone and the overlying tissues.

I didn't read the study closely, I'm not sure if all the implants used in the study were fixated with screws. Also not sure if they considered slightly misplaced implants as well.
Then the material too, seems to play a role.

Considering that <2mm in a <5 year follow up examination seems reasonable for thr chin area. Probably a well fixated medpor implant doesn't cause any measurable resorption in a <5 year period.

The more the implant moves and the more inaccurately it fits onto the underlying bone the higher the resorption afaik.

Take that as a rule for orbital implants too. So yes certainly resorption can occur but much less so in that region so maybe we're talking about 2mm in 10-15 years or so.

Long Term 3D CT Scan Study Of Chin Implant Bone Resorption - Explore Plastic Surgery

Long term 3D CT scan study of chin implants demonstrate a limited and stable amount of bone resorption under the implant with some bone remodeling.

interesting that he says this "Group A showed appositional bone growth and no cortical bone perforation."
so I'm not that paranoid to wonder that, it might be relevant xd

how come? i never seen study or anecdotal report on that

do you know how thick is the cortical bone where they put the screws?

Some studies say it doesn't cause significant resorption, others say it does, personally I would chose the safe option and not get any implants. Eppley is heavily biased btw. so of curse he cherrypicks studes that suppirt his business

 

[Acromegaly_Chad]

Well, Dr. Sailer and Obwegeser told me so. Basically, the more porous the material, the better the muscles and tendons can attach, and thus better the blood supply in the region (alao around the bone) which means it gets better supplied with nutrients etc.

so, according to this, can we say medpor better than peek?

yes he is biased xd
But he is using this source:
In the September 2020 issue of the American Journal of Cosmetic Surgery an article on this topic was published entitled ‘Bone Remodeling Under Screw-Fixed Chin Implants in Patients With Microgenia: A Cross-Sectional Study’.

Well... you could take an exam a few years later to see what happened to your implant in you, how much it reduced the bone layer

One thing I also don't understand is that according to google, the cortical bone of the jaw is 1.59 to 3.03 mm
so 2mm is a lot, so there is the chance that the implant will get stuck till inside the bone, the soft part?
Isn't there where there's blood, bone marrow, etc. Kind of uncomfortable this idea of having the plastic there.

Someone who understood better could clarify this better, completely once and for all, shit.

yes, but its also much easier to break

but you could also make a shit ton of holes on the peek one

Contemporary Understanding of Facial Implant Bone Imprinting By 3D CT Scans - Explore Plastic Surgery

One of the most common misconceptions about facial implants is that they cause bone erosion. Most of this perception comes from the appearance of the bone in profile in chin implants on lateral cephalometric x-rays going back many decades. Other perceptions of this phenomenon are from surgeon’s...
