Perbedaan Proporsi Dimensi Vertikal Menggunakan Metode Willis, Metode Mc. Gee dan Konsep Golden Proportion Berdasarkan Jenis Kelamin dan Suku pada Mahasiswa FKG USU

Abstract

Determination of the vertical dimension is one of the important step in making a full denture, aiming to get the function, occlusion and maximum aesthetic Assortment technique of determining the vertical dimension has been introduced, including a method that has long been popular is the Willis's method and Mc Gee's method, but the problem is not yet known which method to accurately determine the vertical dimension is right for each individual. The vertical dimension is influenced by gender and race Indonesian nation, including the Mongoloid race which consists of Proto-Malays and Deutro-Malays tribes. There were differences between the faces of the size of the tribe Lately known golden proportion concept that can be applied in determining the vertical dimension of a person, who is said to be universal, regardless of race, age, and gender

There are several ways to measure the vertical dimension, they are direct measurement on the face and indirect measurement, such as one digital photo Measurements directly at the patient's face is very dependent on the operator in applying the pressure and the angulation at the time the instrument in contact with the surface of the face If this is not achieved, the resulting data will be inaccurate Unlike the photo measurements, which measure the two-dimensional objects, making it more stable while measuring The purpose of this study was to determine whether there are differences in the proportion of the vertical dimension using Willis's method, Mc Gee's method, and the concept of the Golden Proportion in the Indonesian nation (Proto-Malays and Deutro-Malays tribe) and whether there is a difference between measurements with photos and direct

This type of research is observational analytical. The study was conducted on 92 students who met the inclusion criteria. Then do the direct measurement according to the Willis's method, Mc Gee's method, and the concept of the Golden Proportion Then do the photo shoot samples and measured using Corel Draw Graphics Suite 12 in accordance with the Willis's method, Mc Gee method, and the concept of the Golden Proportion. One Sample T Test conducted to determine differences in the proportion of the vertical dimension using Willis's method, Mc Gee's method, and the concept of the Golden Proportion in the sample and paired T test was conducted to determine differences in photos and direct measurement

The results of this study indicate, there is no significant difference between the proportion of the vertical dimension of Proto Malays's male and McGee's method and in Deutro Malays's women and Mc Gee's method. There were no significant differences between Deutro Malays's men with the concept of the Golden Proportion, among Proto-Malays's women with the concept of the Golden Proportion, and among Deutro Malays's women with the concept of the Golden Proportion. There are significant differences between the Willis's methods to the overall sample. There were no significant differences between the measurements through the images and directly at the partial sample groups, but some groups are more the result is different Determination of the vertical dimension using the concept of the Golden Proportion recommended in this study because of the proportion of the vertical dimension using the concept of the Golden Proportion is more appropriate in the sample group, compared Willis's method and Mc.Gee's method, seen from more groups of samples in accordance with the concept of the Golden Proportion, as well as measurements through better photos than the direct measurement for minimal bias to obtain more accurate data

Keywords the proportion of the vertical dimension, the Willis's method, the Mc Gee's method, the concept of the Golden Proportion, Mongoloid, Proto-Malays Deutro Malays.
