Chin Implants Sizes - Could you help me understand the sizing system for chin implants?

Chin implants come in different shapes, sizes and types.  Which implant is used is dependent on the amount of augmentation needed and the location of where the augmentation is needed along the jawline.  The more commonly used implants are made by Implantech.  You can go to their website to assess sizes and types.

Without an exam your question cannot be answered.  You will need to see an Oral/Maxillofacial surgeon to see if othognathic surgery, genioplasty or using an implant is best for your specific case. It should be noted that patients with severely weak jaws or abnormally functioning jaws may be better treated with other facial surgery (orthognathic surgery), although a chin augmentation may be an option at a later time. These patients should seek the advice of a plastic surgeon to determine which course is right for them. Here is some information to help you make this decision: Candidates for Chin Augmentation - Patients whose chin profiles are weak but have normally functioning jaws are candidates for Chin Augmentation. Many of these candidates have used injectable fillers in the past to strengthen the protrusion of their chins, but are looking for a permanent solution. If you are one of these patients, then you are a likely candidate for chin augmentation

I read your concern, and it's easy to see how you could be confused by Chin Implant sizing. In my practice I mainly use 2 types of chin implants, both manufactured by Implantech. Most of my patients get an "extended anatomical" implant, and the most common size used is a medium. Small and large are used as well, depending on your needs. extended anatomical implants will add between 4-6mm of chin projection.

Some patients with retrusive chins benefit from a "Flower's Mandibular Glove". These look similar to the extended anatomical implants, but these are helpful for adding an upward tilt to the bottom of your chin. These implants will add between 6-10mm of chin projection.

During your consultation, sizers may be used to help determine what would be best for you.

I hope this is helpful.

Chin Implants come in different syles and shapes. Sizers are made which are typically in 3-4 versions, Generally speaking they offer varying amounts of projection ranging from 3mm to 9mm.
 

Chin implants are not soft like breast implants, are made of several different choices of material (solid silicone, e-PTFE, hydroxyapatite, to name a few) and come in different shapes and sizes. They can be used to fill the pre-jowl area (the Mittleman pre-jowl implant) with little anterior augmentation, the entire anterior chin and prejowl area (the Flowers extended anatomic vertical tilt mandibular glove), or just the very front of the chin (the "button" type of implant). Chin implants come in sizes ranging from VVS (very,very small) to XXL, with each implant different from the next by 1mm (or 1/25th of an inch). Custom implants can even be created per your surgeon's direction, and your own bone can be contoured, cut, and reattached using craniofacial techniques.

Sizing your chin implant is something done at the time of consultation with your plastic surgeon, and he or she can help you decide what is best for your anatomy and wishes. If you have orthodontic or bite-mismatch issues, you may be referred to an oral surgeon or orthodontist for correction of these concerns first. I hope this helps!
