[ABSTRAK
Pendahuluan: Model studi konvensional merupakan standar baku (gold
standard) dalam diagnosis dan prosedur perawatan. Penggunaan model studi
digital 3 dimensi dapat menjadi alternatif dari keterbatasan pada model studi
konvensional, antara lain kebutuhan ruang penyimpanan secara fisik, serta
memiliki sifat dapat rusak dan mengalami degradasi dalam waktu lama. Penelitian
ini merupakan kelanjutan dari rangkaian penelitian sebelumnya, yaitu menguji
akurasi diagnosis lengkung gigi rahang atas arah transversal pada model studi
digital 3 dimensi hasil pemindaian laser menggunakan piranti keras yang sama.
Material dan metode: Sampel sebanyak 26 model studi konvensional gigi rahang
atas kasus gigi berjejal sedang-berat. Setiap model studi konvensional dipindai
dengan piranti keras pemindai laser 3 dimensi hingga dihasilkan model studi
digital 3 dimensi. Pengukuran lebar mesio-distal keempat gigi insisif rahang atas,
jarak inter-premolar jarak inter-molar, indeks dan analisis Pont dilakukan pada
kedua model studi. Pengukuran pada model studi konvensional dilakukan
menggunakan kaliper digital (ketelitian 0,01 mm), dan pada model studi digital 3
dimensi dilakukan secara digital dengan piranti lunak pengukur. Dilakukan uji
realibilitas (uji intra eksaminer) dengan plot Bland Altman dan uji t-berpasangan.
Hasil pengukuran kedua model studi dibandingkan dengan uji t-tidak berpasangan
dan dilakukan uji kesesuaian dengan plot Bland Altman. Akurasi pengukuran
lengkung gigi rahang atas arah transversal pada model studi digital 3 dimensi
hasil pemindaian laser diukur melalui uji diagnostik sensitivitas dan spesifitas.
Hasil: Hasil uji intra eksaminer analisis plot Bland Altman menunjukkan sebagian
besar titik berada pada area garis rentang kesesuaian, dan uji t-berpasangan
terdapat perbedaan bermakna antara pengukuran pertama dan kedua pada lebar
mesio-distal gigi 12 dari model studi digital 3 dimensi (p=0,03). Hasil uji
hipotesis dengan membandingkan hasil pengukuran kedua model studi dengan uji
t-tidak berpasangan menunjukkan perbedaan tidak signifikan secara statistik,
dengan nilai p untuk semua pengukuran antara 0,40-0,98. Analisis plot Bland
Altman hasil pengukuran model studi digital 3 dimensi menunjukkan hasil
kesesuaian yang cukup mendekati hasil pengukuran pada model studi
konvensional, dengan nilai bias (mean difference) mendekati 0.00 dan p>0.05
pada semua data. Hasil nilai diagnostik menggunakan analisis Pont untuk melihat
rahang yang mengalami konstriksi dan non-konstriksi dari uji sensitivitas dan
spesifitas menunjukkan sensitivitas sebesar 100% (IK 15,8%-100%), dan
spesifitas 95,8% (IK 78,9%-99,9%).
Kesimpulan: Piranti pemindai laser rakitan Departemen Ortodonti FKG UI dan
STEI ITB akurat digunakan untuk pengukuran dan analisis lengkung gigi rahang
atas arah transversal menggunakan analisis Pont pada model studi digital 3
dimensi kasus gigi berjejal sedang hingga berat.

ABSTRACT
Introduction: Conventional study model is gold standard in diagnostic and
treatment procedure. The use of 3D digital study model can be alternative as a
solution a number of problem issues from conventional study model, such as
require rigorous archiving and massive physical storage space, breakage and
degradation issues in the long term uses. This study purpose to test the accuracy
of transverse measurement the upper arch on digital 3D study models produced by
the same 3D laser scanning hardware which used in the last study.
Matherial and method: 26 conventional study models of the upper arch
moderate-advanced crowding cases as sample. Each conventional study model
was scanned by 3D laser scanning hardware to produced 3d digital study model.
Mesio-distal upper incisors, inter-premolar and inter-molar width, Pont?s index
and analysis was measured on both study models. Measurement were made with a
digital calliper (nearest 0,01 mm) on conventional study model, and digital
measurement by software on 3D digital study model. Reability test
(intraexaminer) by Bland Altman plot and paired t-test. Then measurement result
from both study models are compared using unpaired t-test and Bland Altman
plot. Acuracy of transverse measurement the upper arch on digital 3 dimension
study models from laser scanning performed by diagnostic test sensitivity and
specificity.
Result: The intraexaminer test by Bland Altman showed most of point are in limit
of agreement line, and paired t-test showed significant difference between the first
and second mesio-distal upper left lateral incisor on 3D digital study model
(p=0,03). Hypothesis test by comparing the measurement on both study model by
unpaired t-test showed statistically no significant difference, with p value for all
measurement around 0,40-0,98. Bland Altmant plot showed high compatibility
between conventional study model and 3D digital study model, with mean
difference closed to 0.00 and p>0.05 for all data. Diagnostic test on Pont?s
analysis to classify contriction and non-constriction the upper arch showed
sensitivity 100% (CI 15,8%-100%) and specificity 95,8% (CI 78,9%-99,9%).
Conclusion: 3D digital study model produced by 3D laser scanning hardware
made by Orthodontic Department FKG UI-STEI ITB accurate for transverse
measurement and analysis (Pont?s) on upper arch moderate-advanced crowding
cases.;Introduction: Conventional study model is gold standard in diagnostic and
