Does a chin implant move around or is it secured?
How is a Chin Implant Secured?

Chin Implant fixation
Chin implants are secured by placement inside a well-fitted pocket and anchoring it to surrounding tissue so it doesn't move. I also use a permanent stitch to hold it in the midline position for silicone implants and for Medpore implants a scew is used.The incision is then closed, and in 30 to 45 minutes the procedure is done, unless the patient has requested other procedures as well.
How it is secured depends on implant used and surgeon preference. Some prefer to use bone screws while others just place in a very tight pocket incision and not secure to the bone.
The risk of chin implant movement is very minimal and will not shift if it is secured with implant screws. You are still able to remove the implant if you choose to later in life but this ensures there is no chance of movement unless sever trauma occurs to your facial structure.

Chin implant is held in place with normal scar tissue
If the chin implant pocket is precisely made, the implant will not move. Normal scar tissue forms around the implant and I tell my patients that they could be a boxer in as few as 6 weeks. In other words, you would have to be hit in the jaw so hard, that you would break your jaw before you would move the implant.
I rarely would screw an implant in place, but there are some Doctors who prefer that technique. Discuss this in detail with your surgeon.
Implants may be secured by suture or in some cases bone screws depending on the type of implant. In some instances the pocket made for the implant will hold it in the right position. I do believe it is best to secure the implant in the proper position to prevent migration. Donald R. Nunn MD Atlanta Plastic Surgeon.
Chin Implant Fixation
Fixation of chin implants is something that each surgeon does differently depending on experience, the method of insertion and the type of implant used. I use a bendable implant that can be put in through a small opening into a very tight pocket. Once the opening into the pocket is closed, the implant cannot move, and I have never had one move. Instead of concentrating on the specifics of the procedure, find out what the surgeon’s experience is and whether he/she gets the results you desire with minimal problems.
Chin Implant Technique
When a chin implant is placed a precise pocket is formed involving both the bone and the layer of tissue just above the bone. Whether the surgeon fixates the implant or not is entirely surgeon preference and not something that the patient really has to worry about. Try not to worry too much about the individual steps of the surgery. Find a surgeon that you like and trust and let them decide how to perform the surgery. Good luck!
Chim Implant Methods Of Fixation
The use of any form of securing chin implants varies amongst surgeons. Many surgeons allow the size of the pocket to be the method of keeping the implant in its desired place. Other surgeons will use a resorbable suture placed between the midline of the implant to the midline of the lower jaw tissues. A minority of surgeons will use the most secure method, a screw through the implant into the bone, to provide chin implant fixation. This is my desired method in many chin implants as keeping the implant low on the edge of the chin bone is aesthetically desireable for many patients to add a little vertical height increase as well.
Chin Implant Movement
The risk of chin implant movement is minimal when the implant is placed in a precise pocket and/or fixed with a suture or screw. This is a rare complication. Once the patient has healed, it would take severe force which could break the jaw, to move the implant.
Chin implants are secured in various ways.
Depending on the type of implant and the surgeon's preference, training, and habit, there are different ways of trying to ensure the chin implant doesn't "move around" or become malpositioned during healing.
I use extended anatomic Flowers mandibular glove vertical tilt solid silicone elastomer chin implants the most, as these provide a secure anatomic "fit" with the normal bony contours of the anterior mandible. They almost "snap" into place, but the pocket must be carefully created to be the exact size and position you want the implant to end up in. Exact pocket size is the best way to keep an implant immobile, but there are also permanent or dissolving sutures to hold it in place as the scar heals around it and then it's pretty much "stuck in place!"
Medpore implants have tiny interstices ("pores") into which tissue grows, immobilizing it. Of course, this needs to be kept in proper position until that tissue in-grows, so exact pocket creation again is important, as well as a temporary (or permanent) fixation suture.
Bony chin surgery (sliding genioplasty) involves sawing off the underside of the chin and then advancing it into the desired position and then screwing it into place with titanium plates and screws. This sounds worse than it is, but frankly, though I have had significant craniofacial training and am fully capable of performing this operation, I think it has a proper place in only a minority of patients. The anatomic silicone implants are just that superior, IMHO. They can be easily removed or changed in size also (though this is rarely necessary if your initial choices are good), whereas the bone surgery pretty much is what it is and cannot be easily revised.
Also, while the "invisible" intra-oral incision may seem to be a good way to go, this incision choice has a higher risk of infection than the submental incision (just beneath the chin, where many of us already have a scar from that clonk on our parents' coffee table as a toddler). I prefer the external approach because of the lower infection risk, the better visibility of the mental nerves (these should be preserved to avoid numbness of the lips, gum, and chin), and the fact that, properly closed, it heals nearly imperceptibly. This also allow me to remove the fatty pad under the chin that improves the cosmetic result by an additional factor!
So as you see, it's less about what is used, but rather how carefully the surgery is performed that keeps the implant where you want it. If it "slides around" after surgery, there is no chin strap or elastic chin holder that will secure the implant as well as better surgical technique!
