KESIMPULAN DAN SARAN
6.1 Kesimpulan
Berdasarkan hasil penelitian perubahan indeks tinggi wajah pada perawatan ortodonti maloklusi Klas I dengan pencabutan empat gigi premolar pertama dapat disimpulkan :
1. Ada perubahan indeks tinggi wajah pada perawatan ortodonti maloklusi Klas I
dengan pencabutan empat gigi premolar pertama tetapi perubahan tersebut tidak signifikan.
2. Ada hubungan negatif antara perubahan sudut mandibula Frankfort dengan
perubahan indeks tinggi wajah yang terjadi pada perawatan ortodonti maloklusi Klas I dengan pencabutan empat gigi premolar pertama.
Dari 13 kasus yang diteliti diperoleh hasil ada beberapa pasien yang nilai FHI nya lebih besar dari kisaran normal (0,55 – 0,85) sebelum perawatan di antaranya pasien B, G, I, dan K. Beberapa pasien yang nilai FHI nya lebih besar dari standar normal setelah perawatan di antaranya pasien F, G, dan J. Beberapa pasien yang nilai FMA nya di atas atau di bawah dari standar normal (17 – 28) setelah perawatan di antaranya pasien B, E, H, dan M. Hal ini dapat terjadi karena penggunaan mekanoterapi yang kurang hati-hati selama perawatan. Indeks tinggi wajah perlu di kontrol sebelum, selama dan setelah perawatan.
6.2 Saran
Perlu dilakukan penelitian lebih lanjut dengan menggunakan jumlah sampel yang lebih banyak dan pada pasien yang sudah selesai perawatan, braket sudah dilepas.
