Salah satu pertimbangan dalam menentukan alat ortodontik yang akan digunakan adalah biaya. Alat ortodontik lepasan dipilih karena memerlukan biaya yang lebih rendah dibanding dengan alat ortodontik cekat. Perawatan ortodontik dengan alat lepasan sulit dilakukan jika disertai dengan pencabutan satu atau beberapa gigi posterior. Pasien perempuan usia 23 tahun, mengeluhkan gigi rahang atas maju dan gigi rahang bawah berjejal. Pemeriksaan objektif menunjukkan protrusif rahang atas, crowding rahang bawah, palatal bite, disertai kehilangan gigi 46. Maloklusi Angle Kelas II divisi 1 tipe dentoskeletal, hubungan skeletal klas II, protrusif bimaksilar, bidental protrusif, overjet 7,2 mm, crowding, palatal bite, dan kebiasaan bernafas melalui mulut. Perawatan menggunakan kombinasi alat semi-cekat pada rahang bawah dan alat lepasan pada rahang atas. Alat semi-cekat digunakan untuk space clossing bekas pencabutan gigi 46. Terjadi space closing bekas pencabutan gigi 46 setelah 6 bulan perawatan. Overjet berkurang menjadi 4 mm dan overbite 2,7 mm setelah 1 tahun perawatan. Kombinasi alat semi-cekat pada rahang bawah dan alat ortodontik lepasan pada rahang atas efektif untuk koreksi maloklusi Angle Klas II divisi 1 dengan kehilangan gigi 46 pada pasien ini. ABSTRACT: Orthodontic Treatment Using Semi-Fixed Appliances with Partial Edentulous 46. Cost is one of the considerations in determining the use of orthodontic appliances. Removable orthodontic appliance is chosen because it is less costly than fixed orthodontic appliances. It is difficult to use removable orthodontic appliances to treat a missing one or more posterior teeth case. A 23 year old female patient had a chief complaint of crowding in lower anterior teeth and forwardly placed upper anterior teeth. Her objective examination shows protrution of upper teeth, crowding in the lower arch, palatal bite, and partial edentulous of 46 tooth. It was Angle Class II division 1 dentoskeletal malocclusion, skeletal class II, bimaxillary protrusion, bidental protrusion, overjet 7,2 mm, crowding, palatal bite, and mouth-breathing habit. The treatment used a combination of semi-fixed orthodontic appliances in the lower arch and removable appliances in the upper arch. The semi-fixed orthodontic appliances were used on space closing of partial edentulous 46. The partial edentulous 46 was closed after 6 months of treatment. The overjet was reduced to 4 mm and overbite 2,7 mm after one year of treatment. The combination of semi-fixed orthodontic appliances in the lower arch and removable appliances in the upper arch generate a good result to correct Angle Class II division 1 malocclusion with partial edentulous 46.

The twin-block appliance is a widely used functional appliance for the correction of Class II division 1 malocclusion in growing children and adolescents. This article outlines the indications and case assessment, the steps in clinical management and appliance design. Evidence regarding the mode of action, effects and prediction of treatment outcome of the twin-block appliance for Class II division 1 malocclusion are also presented. CPD/Clinical Relevance: The twin-block appliance is a widely used functional appliance in the UK for the correction of Class II division 1 malocclusion in growing children and adolescents.

Spontaneous improvement in molar occlusion is often assumed to accompany orthodontic treatment of the Class II Division I case where all pre-molars have been removed. The investigation shows that while the buccal occlusion generally improves after the completion of removable appliance treatment this is seldom enough to correct a Class II molar relationship.

Introduction: Malocclusion is one of the most common dental problems observed. Limited data is currently available regarding the demographics of malocclusion observed locally. Materials And Methods: This is a retrospective study where 770 patients were recruited from May 2009 till December 2014. 560 orthodontic study models that met the inclusion criteria were examined and the malocclusions were classified according to the British Standard Institute (BSI) incisor classification.  Demographic pattern and their relationship were analysed by structural equation modelling using SPSS (version 23.0). Results: From 560 study models analysed, 72% were female. The age of the patients ranges from 7-12 years old (17.1%), 13-17 years old (55.9%) and >18 years old (27.0%). Majority of the patients were Malay followed by Chinese (5.7%), Indian (1.8%) and other races (1.8%) Treatments received were fixed appliances (FA) (60.0%), removable appliances (RA) (12.5%), functional appliances (FnA) (1.1%), combination of RA and FA (16.1%), combination of FnA and FA (2.1%) and consultation (8.2%). Types of malocclusions observed were Class I (25.7%), Class II/1(32.7%), Class II/2 (7.5%) and Class III (34.1%). There was significant association (p<0.05) between age and gender towards the types of malocclusions and treatments received were observed. Conclusion: Age and gender play significant role in determining the types of treatment received by patients with malocclusion. Data obtained will be beneficial for departmental future management and clinical planning.
