崇愛牙醫診所(資料重建中,歡迎新舊朋友)

In 1966, Merrifield⁸ developed a specific guide to analyze the patient's facial profile, introducing a profile line, tangent to the soft chin and the most protuberant point on the lip, which he denominated the "Z line". (這是在1966年merrifield所研發的一項特殊的導引,用來分析病人的顏面外觀,是由病人的側面外形,自軟下頦與唇的最突點的連線,構成z line)

That line was extended to the horizontal Frankfort plane so as to compose the Z angle. (這條z line與FH 平面的交角構成Z角)

The author observed that the Z angle presented a medium value of 80° for adults and 78° for subjects from 11 to 15 years of age, with harmonic faces and normal values of FMA, FMIA and IMPA.(Z角的平均角度在男性為80度,而11~15歲的年輕人則約為78度,這是較和諧的外觀,也就是平均值約落在70~80度間,理想的Z角為75度)

The Z angle of the Japanese subjects with normal occlusion was 69.70 degrees for the men and 71.75 degrees for the women(這是日本人的Z角數據)
