Masseter Muscle Dehiscence From Jaw Angle Implants

[randomvanish]

Is it same for custom wraparound jaw implants or is it just happening with the prefabricated sharp angled jaw angle implants ?

Could my muscle have slipped off the angle and if so how do I correct this?

I had mandibular angle implants over a year ago. I started to experience tightness on my left side with my jaw muscles. Upon further inspection my masseter...

I know of one user on here who’s had it. I wonder if risk of this happening dramatically decrease if the surgeon is as skilled as Eppley @RealSurgerymax

Yes probably.

However i wonder that even it's not problematic in first months/years, would it started to become problematic by time and by any kind of impact to the face ? (punch, small accidents etc., not talking about severe impacts like car crash)

Because if i'm correct, implant started to push muscle to create dehisence in a matter of time. If I'm wrong, please correct me dear @RealSurgerymax

- The size and shape of the implant influences the level of risk. It is not necessarily Andy higher or lower with off the shelf vs custom design but is higher in larger implants or any implant that provides vertical augmentation.

- Yes, @PapiMew The experience, technique and care used matters. Comfort in this area could be gained from doing more common procedures like reduction and fixation of jaw angle fractures (since you can’t expect many people to be experienced in jaw angle implants.)

- This is unlikely to be a problem that will ever arise many months or years later. By this time soft tissue has adapted by stretching to accommodate the implant. Furthermore perfusion holes through the implant can help to re-establish bone-to-muscle connection through the collagenous scar tissue that grows through the holes, further anchoring the overlying soft tissue in place. This takes atleast a few months to fully develop.

Not all implants have perfusion holes but they can be a helpful feature.

They need to be manually added to a custom silicone implant after the fact. They cannot be designed in because of the way custom silicone implants are fabricated - prototype model is 3D-Printed, then a mold is made of that which is used to cast the actual implant in long-term implant grade solid silicone.

PEEK Implants which are milled (and can now be 3D printed in the USA with a new FDA Approved PEEK Filament) can be planned and manufactured with perfusion holes.

So does that mean silicone have disadvantages over peek/medpor since they naturally have holes to contact with tissues ?

Jaw implants only really work if your jaw has good growth but lacks mass or if you have a recessed chin but are still forward grown somewhat.
If you have a shit gonial angle it means your entire face is downward grown so using implants to change the angle will only make it look uncanny

i've no recession, only jaw assymetry due to birth defect on the right.
