Q

Konsep kortikal drift?

A

Semua struktur tlg punya prinsip “drift”
Aposisi di 1 sisi : tlg akan menebal
Resorpsi > aposisi : ketebalan tlg berkurang
Resorpsi = aposisi : bergeser tp ketebalan tdk berubah/konstan

Q

Konsep V principle?

A

Eskpansi horizontal/vertikal(?)
Dalam : aposisi
Luar : resorpsi
Shg arah pert keluar & tlg membesar
Pertambahan ukuran & pergerakan pertumbuhan terjadi scr sama2

Q

Konsep Surface principle?

A

pertumbuhan tlg berbeda2 arahnya
Searah dgn arah pert : deposisi
Berlawanan dgn arah pert : resorpsi
Terjadi pd perm tlg kontralateral -> lempeng kortikal ikuti arah pert

Q

Apa itu growth center dan apa saja yg termasuk ke growth center?

A

Daerah yg pert sgt aktif/ cepat & banyak dibanding dgn daerah lain
SCTAS
Sutura wajah & cranium
Condylus
Tuberositas maksilaris
Alveolaris
Sikondrosis basis kranium

Q

Apa itu displacement dan jenisnya?

A

Proses pergerakan scr translasi karena gaya fisik di sekelilingnya
1. Primary : pert dr tlg itu sendiri oleh gaya ekspansif dr jar lunak wajah. Pergeseran berlawanan dgn pert tlgnya. Besar pergeseran = aposisi/resorpsi tlg baru
2. Secondary : bergeser karena pert tlg/jar lunak yg berdekatan

Q

Pert midface?

A

Vertikal : resorpsi di maksila nasal, deposisi di perm palatal shg perkembangan sinus
Ante : premaksila tumbuh ke bawah dan tdk gerak ke dpn

Q

Pert Primary midface?

A

Perkembangan vertikal RA-> primary displacement -> merangsang deposisi tlg pd sutura dgn seimbang

Q

Displacement kompleks nasomaksilaris?

A

Pergerakan gigi RA scr aktif & pasif -> Pergerakan gigi RB & alveolarisnya ke atas -> remodeling dagu, corpus, i RB & alveolarisnya -> i rotasi ke lingual dan gerak ke poste shg hasilin overbite yg baik
Resorpsi : di ante alveolaris
Deposisi : ante & infe kontur luar simfisis shg dagu jd prominent

Q

Indikasi perawatan dini poste crossbite?

A
  • Terjadi shifting slm penutupan rahang
  • kontriksi parah shg mengurangi ruang di RA
    Note : boleh ditunda slm sutura mid palatal blm menyatu (7-8 thn) jd bisa pake alat sederhana & gaya yg ringan

Q

Indikasi perawatan dini ante crossbite?

A
  • ada terbatasnya pergerakan RB ke lateral
  • abrasi insisal
  • resesi gingiva di gigi ante RB
17
Q

Etio ante crossbite?

A

Benih gigi ke palatal
Persistensi
Supernumerary
Trauma
Kekurangan ruang

18
Q

perawatan ante crossbite nonskeletal?

A
  • buat ruang yg cukup untuk pert gigi
  • alat ortho lepasan & cekat yg sederhana
19
Q

Openbite ante terjadi pd?

A

Anak2 dgn ptoporsi fasial dlm arah vertikal yg normal karena sucking habit

20
Q

Efek openbite ante?

A
  • i ra tipping ke labial
  • i rb tipping ke lingual
  • erupsi i terganggu
  • lebar interkaninus & intermolar menyempit
  • rahang bentuk v
21
Q

perawatan openbite ante?

A

Intervensi nondental : edukasi, dll
Terapi alat
