Extent of Hydroxyapatite Chin/Jaw Implant Resoption?


I am considering chin and possibly jaw augmentation. I have previously considered a couple different implant materials (silicone with titanium screw fixation or MEDPOR) as well as sliding genioplasty. Recently, I read about hydroxyapatite implants, which allegedly permit significant bone ingrowth and are eventually incorporated into the bone. However, I have also read that some resorption of the implant can occur before bony ingrowth is complete. To what extent would implant resorption be expected for hydroxyapatite? If after several years resorption is significant but some bony ingrowth has occurred, can an additional implant be placed over the new bone to allow for continued ingrowth? Thank you.

Silicone is still my preferred implant material. It's easy to work with and can be easily removed if needed. Medpor and hydroxylapatite implants can be a real bear to remove if that were (more)

I have both hydroxyapatite granules/paste and implant. It did NOT absorb/resorb. It adheres the skin of jawline area nicely to the bone thus helping the aging process. However, VERY FEW doctors use it. Good luck finding one because no more surgeons are left that actually use skill and artistry. Instead the use prefabricated implants.

The key factor with facial implants is not really the 'material'. Instead it's the SHAPE and FORM. For example if an implant ends up not looking that good on your face, the first thing you will notice is the shape and form is not 'right' for you. Even if the implant is your 'preferred' material.

Thank you for your response.

It seems like these implants are fairly uncommon compared to the other options I mentioned. Do relatively few surgeons use them, or are they just not well-known by patients or expensive? If few surgeons use them, which ones have done the most work with them?

Are there different formulations or treatments for the implant material that affect the rate of resorption?
