[Pendahuluan Kehadiran jenis braket sistem self-ligating pasif menambah variasi jenisbraket yang digunakan dalam perawatan ortodonti saat ini, sehingga timbul pertanyaanmengenai efektifitasnya terhadap perawatan ortodonti. Salah satu parameter yangmenentukan efektifitas tersebut adalah durasi waktu perawatan yang dibutuhkan untukmemperbaiki maloklusi, misalnya kecepatan penutupan ruang secara en-massemenggunakan elastomeric chain.Tujuan Mengetahui efektifitas perawatan ortodonti yang dilakukan menggunakansistem braket self-ligating pasif dan sistem braket konvensional selama tahappenutupan ruang secara en-masse.Metode Penelitian prospective randomized controlled clinical trial dengan teknik splitmouth ini dilakukan selama 11 bulan. Sebelas subyek (3 pria dan 8 wanita usia minimal15 tahun) dengan pencabutan premolar satu rahang atas dan akan memasuki tahapspace closure diikutsertakan dalam penelitian ini. Setiap subyek dipasangkan braketkonvensional di satu sisi rahang dan self-ligating pasif di sisi lainnya, dimanapenentuannya dilakukan secara random, kemudian diberikan gaya sebesar 150 gdengan powerchain pada kawat SS .019 x .025. Pengukuran jarak penutupan ruang dankehilangan penjangkaran dilakukan pada T0, T1 (4 minggu), dan T2 (8 minggu).Hasil Terdapat perbedaan rata-rata kecepatan penutupan ruang yang signifikan antarakelompok sistem braket self-ligating pasif dan kelompok sistem braket konvensional(p=0,010) dimana kelompok braket self-ligating pasif memiliki kecepatan yang lebihbesar dibandingkan kelompok braket konvensional, namun tidak terdapat perbedaanrata-rata kehilangan penjangkaran yang signifikan secara statistik antara keduakelompok tersebut.Kesimpulan Sistem braket self-ligating pasif memiliki efektifitas yang lebih baikkarena dapat mempercepat durasi waktu perawatan ortodonti., Introduction The presences of passive self - ligating bracket system add variety ofbracket type used in today’s orthodontic treatment, so that raised question in regard tothe effectiveness of the treatment. One of the parameters that determines theeffectiveness of the treatment is the time required to fix malocclusion, e.g. rate of en -masse closing space using elastomeric chain.Objectives To study the effectiveness of orthodontic treatment using passive self -ligating system and conventional system during space closure stagesMethods Prospective randomized controlled clinical trial with a split mouth techniquewas carried out for 11 months. Eleven subjects (3 men and 8 women with age minimumof 15 year old) with the extraction of the first premolars, where it will enter the spaceclosure stage were included in this study. Each subject was bonded with conventionalbracket on one side of the arch and with passive self - ligating on the other side whichwas determined randomly, was given a force of 150 g with power chain on .019 x .025SS wire. The measurement of space closure and loss of anchorage were performed atT0, T1 (4 weeks), and T2 (8 weeks).Result There was significant differences of the average rate of closing space betweenpassive self - ligating system and conventional system group (p = 0.010), for which agroup of passive self - ligating system has a greater speed compare than conventionalgroup, though there was no difference in loss of anchorage between the two groups.Conclusion The passive self - ligating system is more effective because it can reducethe duration of orthodontic treatment] |
