Pendahuluan: Perbaikan susunan gigi geligi dan oklusi dapat dilakukan dengan perawatan ortodonti. sifat kooperatif pasien sangat berpengaruh dalam kemajuan perawatan dan memerlukan waktu yang panjang. Tujuan penelitian adalah mengetahui kemajuan perawatan pasien dengan sekrup ekspansi rahang atas pada alat ortodonti lepasan di Rumah Sakit Gigi dan Mulut Fakultas Kedokteran Gigi Universitas Padjadjaran. Metode: Jenis penelitian yang digunakan adalah deskriptif. Teknik pengambilan sampel dilakukan secara purposive sampling dengan kriteria yang ditentukan, sebanyak 20 model studi crowding ringan yang dirawat menggunakan sekrup ekspansi rahang atas pada alat ortodonti lepasan. Hasil: kemajuan perawatan dengan mengaktivasi sekrup ekspansi secara rutin menunjukan terdapat pertambahan lebar lengkung gigi (LLG) serta jarak gigi 14-24 sebesar 49,1% (bermakna) dan 16-26 sebesar 33,8% (bermakna). Simpulan: Kemajuan perawatan dapat terjadi setelah aktivasi sekrup ekspansi sejumlah 9-10 kali, dimana jumlah aktivasi dan interval hari sebesar 49,1% dan 33,8% sehingga diperoleh ruang untuk memperbaiki susunan gigi pada pasien dengan crowding ringan.Kata kunci: sekrup ekspansi rahang atas, crowding ringan. ABSTRACTIntroduction: Improvement of the tooth and occlusion arrangement can be performed with orthodontic treatment. Cooperativeness of patients will be very influential in the treatment progress which requires a long time. The study was aimed to determine the development of a treatment with maxillary expansion screws on removable orthodontic appliances at Dental Hospital of Faculty of Dentistry Universitas Padjadjaran. Methods: The research was descriptive. The sampling technique was purposive sampling with the specified criteria, as much as 20 study models of mild crowding were treated using maxillary expansion screws in the removable orthodontic appliance. Results: The treatment progress by activating expansion screws continuously showed that there was an increase in the dental arch width and a distance of tooth number 14 – 24 was 49.1% (significant), and a distance of tooth number 16 – 26 of 33.8% (significant). Conclusion: Treatment progress can occurred after activation of expansion screws 9-10 times, where the number of activations and interval days was 49.1% and 33.8% so that space was obtained to improve the tooth arrangement in patients with mild crowding.Keywords: Maxillary expansion screw, mild crowding.

Introduction: Expansion appliance that can imply tooth movement and opening maxilla suture might affect the blood vessels, bone cells, and formation of the new bone. HBOT accelerated the rate of osteoblast differentiation leading to an increase in bone formation during osteonecrosis. Research about HBOT during maxillary suture expansion has never been investigated. The purpose of this research was to correlate the blood vessels number, osteoblast by administered 2.4 ATA HBOT from day 8-14 to imply new bone formation during maxillary suture expansion. Methods: Eighteen male guinea pigs with randomised post-test only control group design divided into 3 groups. Negative control group K(-), positive control with expansion appliance K(+), expansion appliance and HBOT (P). After 14 days guinea pigs were decapitated. Histological slide of the blood vessels number, osteoblast, and new bone formation were examined under a light microscope then were analysed by regression test. Results: Descriptive test showed increasing blood vessels number, osteoblast, and new bone formation on the administration of HBOT during maxillary suture expansion. Regression test showed that there was a strong correlation between the blood vessels number and osteoblast to the new bone formation with R=6.95 during maxillary suture expansion. Conclusion: 2.4 ATA HBOT influences the intercausal relationship between increasing blood vessels number, increasing osteoblast, and new bone formation during maxillary suture expansion.

Introduction: Cephalometric analysis have been widely used in orthodontics. The analysis can be conducted in two methods: conventional and digital methods. Practitioners prefer using computerized cephalometric analysis due to its simplicity and less time-consuming compared to manual or conventional method. The objective of this study was to identify discrepancies between Conventional Steiner cephalometric analysis and digital cephalometric analysis using CephNinja® Application. This study was an experimental in vivo study with descriptive and comparative approach. Methods: Thirty two negative and digital cephalograms were traced manually using Steiner analysis and digitally using CephNinja® software application. Tracing results of manually analyzed cephalogram and digitally analyzed cephalogram were then compared. Results: There were no distinguished discrepancies between the tracing results of both manually and digitally analyzed cephalogram using Steiner analysis. Conclusion: there was no significant difference of steiner cephalometric analysis conducted using conventional tracing and digital method using CephNinja® application software.

Introduction: Third molar impaction has been a controversial topic among clinician when it comes to mandibular anterior teeth crowding. The aim is to know the prevalence of third molar impaction in patient with mandibular anterior teeth crowding in Orthodontic Department, Dental Hospital Universitas Padjadjaran (RSGM UNPAD), Indonesia. Methods: This was a descriptive research, with non-probability sampling obtained from a population with full arch 32 teeth. Totaling 54 samples from year 2011 to 2014 were obtained. The age of sample range from 15 to 25 years old. Also all panoramic radiographs taken from the year 2011 to 2014 were examined using a computer.The position of third molars were determined by Winter's classification using angle formed between the intersected longitudinal axes of the second and third molars and anterior teeth status by using Little's irregularities index. Results: This study obtained data that as much as 68.52% mesioangular third molar, 19.44% distoangular, 4.63% horizontal, 1.85% buccolingual, and 0% others. In mesioangular impaction condition there was crowding 83.78%, in distoangular condition there was 100% crowding, in horizontal position crowding found 100%, while at buccolingual crowding found 100%.Conclusion: In all positions the third molar impaction was accompanied by crowding of the mandible anterior teeth, with the largest percentage of impaction was the mesioangular position
