![]() ![]() The ideal gonial angle for women is 122 ± 4 degrees and a mandible height of 43.4 mm. Additionally, the angles and shape of his jaw are nearly perfect.Ī 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 125 degrees.Ĭlick here to learn more about the ideal jaw proportions for men. His jaw is huge, but his overall head and features are wide, so it works for him. However, his mandible suits his face (which is already well-proportioned), so it may not suit everyone.įor instance, Sean O’Pry has an ideal mandible. What Is the Ideal Male Mandible?Īs mentioned earlier, the ideal male mandible would be Robert Pattinson’s mandible. Again, it can vary for each person, but it is more likely that an African mandible may protrude from the rest of the face. Another example would be how an African mandible tends to protrude more than an Asian and European mandible.African mandibles often have slightly curved gonion, whereas Europeans often have flatter edges.On the other hand, Caucasian and African jawbones tend to rise and fall along the lower border. The gonions of an Asian mandible tend to curve sharply.The bottom of the Asian mandible will likely keep contact with the surface all the way around. For example, let’s say that we put an Asian mandible onto a flat surface.However, some noticeable factors can help determine someone’s race by analyzing their mandible. There is some room for error since everyone is different. The mandible tends to vary based on race. Can You Tell What Race Someone Is by Looking at Their Mandible? Many females, especially if they have an oval face shape, have jaws that taper from the jaw angle to the chin. Females have less gonial eversion, and it may invert towards the midline.Īs for the chin, female chins tend to be more pointed and/or rounded. Most women have a gonial angle that is up to 140 degrees. The gonial angle of women tends to be greater. 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. For instance, the gonial angle tends to be more obtuse for women. The overall female’s skull tends to have smoother bone surfaces and angles. That may be why a typical image of a masculine jaw features a sharp, vertical ramus. The ramus of the male jaw is noticeably more vertical. As for gonial eversion, males often have rugose muscle attachments curving outward, everting from the mandible’s surface. The angle for males is around 130 degrees, but closer to 90 degrees than women are. The gonial angle of the male is formed by the ascending ramus and body of the mandible. The area around the gonial angle can be flared in more extreme cases. Each man’s chin shape can differ, but male chins tend to be much squarer than females. The male mandible often features a larger, squarer chin. Additionally, the mandible tends to resist post mortem changes, so it is of prime importance when determining the skeleton’s sex. The accuracy percentage may be because males can still have pointed chins, females can have squarer chins, etc.īut 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. However, males will still tend to have longer mandibles than women.Īnother 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). Women tend to experience an increase in growth earlier than men. ![]() The study also notes a difference between men’s and women’s increase in mandibular length growth. The study noted that the mandibular length between men and women was rather significant, with males having greater mandibular length than females. One study looks into the differences between male and female mandibles ( Azhari et al., 2019). However, other bones, including the mandible, differ in their characteristics, so the male and female mandible will have different features. Typically, we can often guess whether a skeleton is male or female by looking at the pelvic bone. The Male and Female Mandible: What’s the Difference? Sex Determination. ![]() However, there is some room for those features to vary as each person’s mandible is unique. Some differences between male and female mandibles include thickness, length, shape, angle, etc. When you look at a female and male mandible, it may not be easy to see the differences between the two immediately. ![]()
