“…MARPE is a tooth and tissue-borne expansion appliance in which forces are delivered primarily to the four anchoring mini-implants 14,15 causing more skeletal expansion than dental expansion. This, in turn, decreases the load on the buccal periodontal ligament of teeth reducing chances of root resorption.…”

Introduction -Transverse discrepancies of the maxilla are one of the most prevalent skeletal problems. Due to drawbacks of conventional RPE and invasive surgical expansion methods alternative methods were developed such as Mini Implant-supported rapid maxillary expansion (MARPE).Haas17 , Davis and Kronman18, Akkaya et al19 and many other studies have reported the maxillary response after MARPE on the sagittal dimensions, but their results were inconclusive. Aim - This study analyzed the effects on the maxilla in the sagittal dimension after Mini Implant assisted rapid palatal expansion (MARPE) in adolescents using CBCT. Material and method -A pretreatment CBCT image (T1) was taken as a standard initial record for all patients and post treatment CBCT (T2) was taken after three months in retention. The parameters SNA angle, Frankfort horizontal plane to NA angle, A-N perpendicular, ANS –PNS were measured and calculated for evaluation of the sagittal maxillary changes. Comparisons were then made between the two treatment groups (T1, T2). Result -There was a positive increase in both angular and linear measurements from pretreatment to post treatment measurements showing significant skeletal changes in sagittal dimension. Conclusion -The study concludes that there was statistically significant forward displacement of maxilla after transverse skeletal expansion in patients with transverse problems achieved through MARPE in adolescent patients.

ABSTRAK Pendahuluan: Penggunaan alat ortodonti lepasan dengan sekrup ekspansi bertujuan untuk memperoleh ruangan pada kasus gigi berjejal dengan cara melebarkan lengkung gigi. Pergerakan gigi yang dihasilkan dapat berpengaruh pada salah satu komponen estetika wajah yaitu profil jaringan lunak. Tujuan penelitian ini untuk mengevaluasi perubahan profil jaringan lunak bibir sebelum dan setelah perawatan ekspansi lengkung gigi menggunakan alat ortodonti lepasan. Metode: Jenis penelitian ini adalah deskriptif analitik menggunakan metode purposive sampling pada subjek yang merupakan pasien ortodonti di Klinik Profesi Dokter Gigi RSGM Unpad yang dirawat menggunakan alat lepasan akrilik dengan sekrup ekspansi lateral maksila dan mandibula. Terdapat 4 subjek yang memenuhi kriteria inklusi yaitu sepuluh kali aktivasi yang dilakukan setiap minggu dalam waktu tiga bulan. Subjek dilakukan foto lateral wajah dengan posisi standar sebelum dan setelah aktivasi. Pengukuran dilakukan menggunakan jangka sorong digital dari bibir atas (Ls) terhadap E-line (Ns-Pog), bibir bawah (Li) terhadap E-line (Ns-Pog), dan busur derajat digital untuk mengukur sudut nasolabial(Ns-Sn-Ls). Hasil dan Pembahasan: Nilai rerata perubahan jarak bibir atas terhadap E-line yaitu 0,59 mm, nilai rerata perubahan jarak bibir bawah terhadap E-line yaitu 0,63 mm dan nilai rerata perubahan sudut nasolabial yaitu -2,03o. Penelitian ini menunjukkan adanya perubahan posisi bibir menjadi lebih ke anterior setelah dilakukan aktivasi sekrup ekspansi lateral rahang atas dan rahang bawah sebanyak 10 kali. Simpulan: Hasil penelitian menunjukkan adanya perbedaan yaitu posisi bibir atas dan bibir bawah yang menjadi lebih ke anterior dan tidak terdapat perbedaan pada sudut nasolabial setelah dilakukan 10 kali aktivasi sekrup ekspansi lateral pada alat ortodonti lepasan.Kata kunci: perbedaan profil jaringan lunak; alat ortodonti lepasan; ekspansi lengkung gigi; sekrup ekspansi. ABSTRACT Introduction: The use of removable orthodontic appliance with expansion screws aim to gain a space in crowding teeth by expanding the dental arch. The resulting tooth movement can affect one of the aesthetic components of the face, the soft tissue profile. The aim of this study to evaluate the change of lip soft tissue profile before and after treatment of dental arch expansion using removable orthodontic appliance. Method: The research method used is descriptive analysis and purposive sampling in patients of Rumah Sakit Gigi dan Mulut Universitas Padjadjaran’s Orthodontic Clinic treated by using removable appliance with lateral expansion screw in maxilla and mandible. There are 4 patients who meet the inclusion, namely the srew is activated 10 times, once every week in 3 months. Subjects photographed in lateral position before and after activation. Measurement is done by using a calipers from upper lip to E-line, lower lip to E-line, and nasolabial angle using a digital protractor. Results and Discussion: The average of the changes in upper lip to E-line distance are 0,59 mm, the average of the changes in lower lip to E-line distance are 0,63 mm, and the average of the changes in nasolabial angle are -2,03o . This study showed a lip position that became more anterior after 10 times the activation of the maxillary and mandibular expansion screws. Conclusions: The results showed a difference in the position of the upper lip and lower lip which became more anterior and there is no difference in nasolabial angle after 10 times the activation of lateral screws in removable appliances.Keywords: soft tissue profile differences; removable orthodontic appliances; dental arch expansion; expansion screws.
