The chin is the forward pointed part of the anterior mandible (mental region) below the lower lip. A fully developed human skull has a chin of between 0.7 cm and 1.1 cm.
Symptoms of small chin
There may be an indentation or "notch" in the lower lip where it meets the chin. The lower jaw may be underdeveloped or set back further than usual. The chin may appear to be "hollow" or lack definition. The individual may have difficulty chewing food properly.
Large Chin: A large chin is primarily a personal aesthetic concern. If the size of the mandibular protuberance is disproportionate to other facial features, or overpowers the jaw and mouth area, one may feel their chin is too broad.
People with long chins tend to be artistic and expressive. They're also faithful, caring and sympathetic. If you go to them with a problem, they genuinely care about helping you in your time of need. Not surprisingly, people with this chin type tend to make friends easily anywhere they go.
A receding chin is also known as retrogenia or a weak chin. Instead of jutting out or lying flat, a receding chin slopes back toward the neck. It happens when the lower jaw – or mandible – is out of alignment with the upper jaw. It's most often a cosmetic issue, but it can be related to more serious health concerns.
Diamond. The diamond shaped face is the rarest of face shapes, and is defined by a narrow forehead, wide cheekbones and a narrow chin.
Heart-shaped/V-shaped chin - Scarlett Johansson
This is the shape desired most of all by women when seeking changes to the shape of their chin. Dr Julian De Silva said: 'This slightly V-shaped or heart-shaped chin is the most desirable. You can see its shape very clearly in Scarlett Johansson's beautiful face.
Ideally, when viewing your face in profile, the forward-most point of the chin should be on the same vertical plane as the forward-most point of the lower lip. A chin that ends behind this point is considered a recessed or “weak” chin.
For their research, the surgeons obtained serial radiographs of eight men and eight women, and discovered that, over their lifetimes, the patients' mandibles continued to grow and widen as they aged.
Chin reduction surgery is a procedure to reduce the size of your chin. You may have this procedure if you feel your chin is very long, wide or projects too far past your nose. The surgery can help improve the balance between your chin and your other facial features.
If you have a protruding jaw, talk to your healthcare provider. They can help determine if prognathism is simply a cosmetic issue or if it's interfering with your health and function. If your condition causes serious issues — such as difficulty chewing, speaking or breathing — call your healthcare provider right away.
For patients who find their chin too big, square or long in comparison to their face – a chin reduction could be a way to address this. As opposed to a chin augmentation, a reduction of the chin is a more complex surgery that will involve interference with the jaw bone itself.
Your Bones Can Change with Age
They measured the length, width, and angle of the jaw in each scan. They found that the angle of the jaw between the horizontal and vertical parts increases with age, causing the jaw to jut forward but at a lower height.
Prognathism is a descriptive term for a jaw (upper or lower) that protrudes forward beyond the plane of the face. Occlusion refers to the alignment of teeth and the way that the upper and lower teeth fit together (bite). Malocclusion is the most common reason for referral to an orthodontist.
People have vertically long chins because of too much bone development and the height of the chin bone below the roots of the teeth is too long. But people with long chins often have no functional problems with the jaw or teeth.
Skin becomes loose and sagging, bones lose their mass, and muscles lose their strength as a result of time spent living life. Most people begin to notice a shift in the appearance of their face around their 40's and 50's, with some also noticing a change in their 30's.
Round faces tend to age very well compared to other face shapes due to the fact they store a lot of fat in the cheek area. This can keep you looking younger for longer than those who lose fat quicker. This means that a gaunt and dull complexion takes longer to develop.
However, if the upper third (forehead) and the middle third(nose) are equal and the lower third is short then your chin is too small. We then evaluate the profile. If the chin does not project to the level of the base of your nose, then you have a weak chin.
Research from the University of St Andrews shows that attractive female faces typically possess more feminine features such as a smaller chin and higher cheekbones. A study suggested that broader and longer chin, often seen in males, is usually perceived as less attractive in females.
The ideal chin should be two-thirds of the length of the lower face, as measured from the bottom of the nose to the bottom of the chin. A chin implant can be done as a stand-alone procedure or at the same time as a neck-lift or a facelift. Square shaped chin implants give a more masculine appearance.
Determine the shape of your jaw.
Your jawline shape can further determine your face shape—if it's short or rounder, your face is round. If your jawline is pointy and narrow, your face is heart-shaped. If you have a strong jawline with sharp angles, that's further evidence your face is square.
The V-shaped jawline occurs when the whole face is slim, with a defined jaw that goes straight into a point. Unlike other jawlines, there aren't any other bumps along the way – it's totally flat down to the point of the chin.
"A strong jawline usually means you have a square or rectangle face shape. If your jawline comes to a point then you have a heart-shaped face," Oquendo said. Finally, check out the length of your face. Rounder faces are typically on the shorter side and oval faces are usually on the longer side.
