What Makes The Perfect Jaw ?

Introduction

When it comes to the overall attractiveness of the human face the jaw (lower third) is one of the most important facial features alongside the eyes and the maxilla , most male and female celebrities have a top notch wide , symmetrical jaw with the right angles and measurements that back it up.

So in today's blog post we'll be discussing what makes an attractive male and female jaw while understanding their differences.

The Differences

A fun fact we use the differences in measurements in the jaw of a skull to determine the gender of a skeleton which goes to show you that there is in fact a significant difference between male and female lower thirds.

One study looks into the differences between male and female mandibles (Azhari et al., 2019). The study noted that the mandibular length between men and women was rather significant, with males having greater mandibular length than females. The study also notes a difference between men’s and women’s increase in mandibular length growth. Women tend to experience an increase in growth earlier than men. However, males will still tend to have longer mandibles than women.

Another study shows that the parameters used in their study only gave about 60% accuracy when determining the sex of the mandible (Sharma et al., 2016). The accuracy percentage may be because males can still have pointed chins, females can have squarer chins, etc.

But why does the mandible matter when determining the sex of a skeleton? Most researchers look into this because the mandible is the most sexually dimorphic skull bone, which helps determine gender. Additionally, the mandible tends to resist post mortem changes, so it is of prime importance when determining the skeleton’s sex , so lets look at the different characteristics.

Male Mandible Characteristics

The male mandible often features a larger, squarer chin. Each man’s chin shape can differ, but male chins tend to be much squarer than females. The area around the gonial angle can be flared in more extreme cases.

The gonial angle of the male is formed by the ascending ramus and body of the mandible. The angle for males is around 120 degrees, but closer to 90 degrees than women are. As for gonial eversion, males often have rugose muscle attachments curving outward, everything from the mandible’s surface.The ramus of the male jaw is noticeably more vertical. That may be why a typical image of a masculine jaw features a sharp, vertical ramus.

Female Mandible Characteristics

The overall female’s skull tends to have smoother bone surfaces and angles. For instance, the gonial angle tends to be more obtuse for women. Of course, women can have squarer chins and jaw angles (as seen in some models), but it is more common to see slightly rounder jaw angles.

The gonial angle of women tends to be greater. Most women have a gonial angle that is up to 140 degrees. Females have less gonial eversion, and it may invert towards the midline.

As for the chin, female chins tend to be more pointed and/or rounded. Many females, especially if they have an oval face shape, have jaws that taper from the jaw angle to the chin.

The Ideal Male Jaw

Now that we know where the differences are, let's take a look at what makes the ideal male and female jaws . We will start with the male jaw.

A male’s ideal jaw proportions have a ratio of 5:7 ramus to mandibular body length, a facial angle of 90-92 degrees, a mandibular plane angle of 26 degrees, a bigonial width of 99-113 millimeters, and a gonial angle of fewer than 120 degrees now of course it needs to be proportionate to the face if the jaw is wide then the rest should be wide as well example , robert pattinson , johnny depp and sean o'pry, well what about womens jaws then what makes them ideal ?

The Ideal Female Jaw

The ideal gonial angle for women is anything between 118 to 126 degrees and a mandible height of 43.4 mm. However, it does not have to be this exact; most women can get away with almost any mandible size and shape as long as it is in harmony with the rest of their face, this is why it's a nightmare to rate womens faces they can just look good in a lot of measurements as long as its proportionate. The ideal female mandible can range from the smooth, even jawline of Bella Hadid to a dainty and narrow mandible like Scarlett Johansson. However, some women sport stronger jawlines that still look good. For instance, Angelina Jolie has a somewhat square jaw shape, which flatters her because of her overall facial proportions. Additionally, she has a well defined yet slightly soft chin that keeps her looking feminine. It would also be important to note that her other facial features (lips, eyes, etc.) are very feminine.

Conclusion

This goes to show you that the average woman most of the times looks better than the average man and that's because of their flexibility and ability to look good with a wide range of facial features while for men that criteria is much tighter.
