ABSTRAK
Densitas tulang alveolar merupakan kepadatan unsur mineral pada daerah
tertentu di tulang alveolar. Salah satu penyebab penurunan densitas tulang
alveolar adalah karena gaya yang diaplikasikan dari alat ortodonti. Nilai densitas
dapat diukur menggunakan alat radiografi, yaitu Cone Beam Computed
Tomography (CBCT). Tujuan penelitian ini adalah mendapatkan nilai densitas
tulang alveolar pascaaktivasi alat ortodonti lepasan dan memberikan informasi
pencitraan keadaan densitas kepada dokter gigi dengan menggunakan CBCT.
Penelitian ini merupakan penelitian deskriptif dengan teknik pengambilan
sampel menggunakan Accidental Sampling. Sebanyak 6 orang sampel diberikan
paparan radiasi dengan teknik CBCT sesaat setelah dilakukan aktivasi antara
rentang 8-12 kali.
Hasil penelitian menunjukkan rata-rata nilai densitas tulang alveolar
pascaaktivasi alat ortodonti lepasan sebesar 642,3 HU untuk anterior maksila dan
706 HU untuk anterior mandibula. Selain itu, nilai densitas terrendah didapatkan
pada tulang alveolar di daerah servikal gigi. Sehingga dapat disimpulkan terjadi
penurunan nilai densitas tulang alveolar pascaaktivasi alat ortodonti lepasan pada
regio anterior mandibula dan di tulang alveolar sekitar servikal gigi.

ABSTRACT
The density of alveolar bone was density of minerals in some certain areas
in alveolar bone. Decrease in the density of alveolar bone could be caused by
force which was produced by application of removable orthodontic appliances.
The value of alveolar bone’s density could be measured by radiography imaging
technique named Cone Beam Computed Tomography (CBCT). The objective of
this research was to describe value of the alveolar bone’s density in postactivation
of removable orthodontic appliances and to provide information for
dentists about alveolar bone’s density imaging using CBCT technique.
This study was a descriptive research which used an accidental sampling.
Six patients were given exposure to radiation with CBCT technique shortly after
carried out the orthodontic appliances activation in the range of 8-12 times.
The result shows the average of value of alveolar bone’s density in postactivation
of removable orthodontic appliances are 642.3 HU in the anterior
region of maxilla and 706 HU in anterior region of mandible. Besides, the lowest
value of alveolar bone’s density is obtained in cervical region of the teeth. In
conclusion, there is a decrease in the density of alveolar bone in post-activation of
removable orthodontic appliances in anterior region of mandible and in cervical
region of the teeth.
