Perbedaan Proporsi Lebar Gigi Anterior Rahang Atas terhadap Konsep Golden Proportion, RED Proportion dan Preston's Proporlion Berdasarkan Tipe Wajah pada Mahasiswa FKG USU
Abstract
Esthetic management in prosthodontic treatment is one of the thing that needs to be considered in denture making process. One of the important procedure in denture making that supports the esthetic of the patients facial and dental appearance is the arrangement of anterior maxilla element. The concept of a harmonic dentures esthetic that appropriate with patient facial type and appearance is one of the purpose that needs to achieved in treatment with denture. Generally, there are three facial type which are euryprosopic, mesoprosopic, and leptoprosopic. There are several esthetic concept in dental treatment that can be used to create a harmonic anterior teeth, like golden proportion, recurring esthetic dental (RED) proportion, and Preston's proportion concept. Validity of these concepts is still uncertain to be used as general The purpose of this research was to find the difference of anterior maxilla tooth width proportion towards the concept of golden proportion, recurring esthetic dental (RED) proportion and Preston's proportion based on FKG USU students facial type
This research was an analytic observational research that collect the data of anterior maxilla tooth width size with cross sectional approach using a photo from frontal view as a data collecting device. Samples in this research were FKG USU students with total 102 people, consists of 34 people with curyprosopic facial type, 34 people with mesoprosopic facial type, and 34 people with leptoprosopic facial type. Sample determination was based on the inclusion criteria and facial index, then frontal view photography were made to determined the facial type. To digitally analyzed the teeth size and anterior maxilla tooth width proportion and the data were statistically test with one sample t-test.
Results showed that anterior maxilla tooth width proportion there were significant difference (p<0,05) with golden proportion based on three facial type in man or woman, there were significant difference (p<0,05) with RED proportion in caninus towards lateral incicor proportion in man and women from three facial type. There were no significant difference (p>0.05) with Preston's proportion concept in lateral incicor towards the central incicors width proportion and caninus towards lateral incicor width proportion in woman based on three facial type.
Results showed that the Preston's proportion concept is more suitable as the esthethic concept in this sample on eryprosopic, mesoprosopic, or leptoprosopic facial type. Pengelolaan estetis dalam perawatan prostodonsia merupakan salah satu hal
yang harus dipertimbangkan dalam tahap pembuatan gigi tiruan. Salah satu tahapan-'-
p""ti"s dulu- pembuatan grgr fri.lan yanE mendukung-penampila{ wajah dan gigi
pasien yang estetis adalah penyusurran anasir gigi tiruan anterior rahang atas. Konsep
estetis gigi tiruan yang harmonis sesuai dengan tipe wajah serta penampilan pasien
merupakan salah satu tujuan yang harus dicapai dalam perawatan dengan gigi tiruan.
Tipe wajah secara umum dikenal ada tiga yaitu eurltprosopic, mesoprosopic dan
leptoprosopic. Berbagai korsep estetis dalam perawatan gigi unnrk menciptakan gigi
anterior yang harmonis, beberapa diantaranya yaitu konsep golden proportion,
recttrring esthetic dental (RED) proportion dan Preston's ProPortion. Validitas
konsepkonsep tersebut masih diragukan untuk digunakan secara umum. Penelitian
ini bertujuan untuk mengetahui perbedaan proporsi lebar gig anterior rahang atas
terhadap kon*ep golden proportion, recurring esthetic dental (RED) proportion dan
Preston's proporlrbz berdasarkan tipe wajah pada mahasiswa FKG USU.
Jenis penelitian yang digunakan adalah penelitian observasional analitik yang
mengumpulkan data ukuran lebar gigi anterior rahang atas dengan pendekalan cross
sectional menggunakan foto dari tampilan depan sebagai alat pengumpulan data.
Sampel pada penelitian ini adalah mahasiswa FKG USU dengan jumlah sampel 102
orang, terdiri dari 34 ofimg dengan tipe wajah euryprosopic,34 orang dengan tipe
wajah mesoprosopic dan 34 orang dengan tipe \\14ah lePtoProsoprc. Penentuatr
sampel berdasnrkan kriteria inklusi dar, focial izder, kemudian dilakukan
pengambilan foto dari arah depan untuk menenhrkan tipe wajah. Untuk menganalisis
ukuran gigi dan pncporsi lebar gigi-geligi anterior rahang atas secara digital datr diuji
secara statistik dengat luji one sample t-test.
Hasil penelitian menunjukkan p'ropotsi lebar grgr anterior rahang atas ada
perb€daan sigrifikan (p < 0,05) dengm golden propottion berdasa*an ketiga tipe
wajah baik pada laki-laki maupun percmpuan, ada perbedaan sigrrifikan (p < 0,05)
dengart RED proportion pada proporsi kaninus terhadap insisivus lateralis pada lakilaki
dan peremprum dari ketiga tipe wajah. Tidak ada perbedaflr (p > 0,05) dengan
konsep Preston's proportion pada proporsi lebar insisivus lateralis terhadap insisivus
sentralis dan proporsi lebar kaninus terhadap imisivus lateralis perempuan
berdasarkan ketiga tipe wajah.
Hasil penelitian menunjukkan konsep Preston's proportion lebih sesuai
sebagai konsep estetik pada sampel penelitian ini baik pada tipe wajah euriprosopic,
mesoprosopic matpun le ptoprosopic.
