Adjunctive orthodontic management of a missing upper right central incisor in a 12-year-old male using a fixed orthodontic appliance

This article presents a successful orthodontic management of a 12-year-old male using a fixed orthodontic appliance (straight wire technique). His orthodontic treatment was hinged on creating enough space to accept an artificial tooth, correcting the horizontal and vertical relationships of the upper incisors to the lower and the midline shift. Ultimately, an esthetic smile was achieved; function and self-esteem were improved when the artificial tooth was finally fixed.

Occlusal outcome after orthodontic treatment with preadjusted straight-wire and standard edgewise appliances

Purpose Orthodontic fixed appliances have been proven to be effective in treating a wide variety of malocclusions, and different types of appliances have emerged during recent decades. However, the comparative effects of different appliances have not been adequately assessed. Thus, the aim was to assess the occlusal outcome of orthodontic treatment with preadjusted straight-wire (SWIRE) and standard edgewise (SEDGE) appliances. Methods In all, 56 patients (mean age: 13.5 years; 45% male) receiving extraction-based treatment with either SWIRE or SEDGE appliances were included. Between-group differences in the occlusal outcome assessed with the American Board of Orthodontists Objective Grading System (ABO-OGS) and treatment duration were analyzed statistically at the 5% level. Results The average ABO-OGS score was 31.3 ± 7.2 points and 34.0 ± 10.4 points in the SWIRE and SEDGE groups with no statistically significant difference between groups (P = 0.26). Treatment duration was significantly shorter in the SWIRE group compared to the SEDGE group, with an average difference of −6.8 months (95% confidence interval [95% CI] = −9.6 to −4.0 months; P < 0.001). Likewise, fewer visits were needed with SWIRE compared to SEDGE appliances with an average difference of −7.2 visits (95% CI = −10.3 to −4.2 visits; P < 0.001). Adjusting for the influence of any potential confounders did not considerably impact the results. Conclusion Similar treatment outcomes were observed after premolar extraction treatment with SWIRE and SEDGE appliances. On the other hand, SEDGE appliances were associated with prolonged treatment duration and more visits needed to complete treatment compared to SWIRE appliances.

Penatalaksanaan perawatan maloklusi dentoskeletal kelas III disertai crowding ringan dan masalah tooth size discrepancy menggunakan reduksi interproksimalManagement of Class III dentoskeletal malocclusion treatment with mild crowding and tooth size discrepancy problems using interproximal reduction

Pendahuluan: Pasien yang telah melewati masa tumbuh kembang dapat dirawat dengan perawatan ortodonti kamuflase atau bedah ortognati. Perawatan ortodonti kamuflase dengan hasil yang cukup baik dapat dilakukan jika diskrepansi skeletal tidak terlalu berat. Laporan kasus ini bertujuan untuk mengetahui keefektifan penatalaksanaan perawatan maloklusi skeletal kelas III dengan perawatan ortodonti kamuflase. Laporan kasus: Pasien perempuan, berusia 16 tahun 7 bulan, datang ke klinik PPDGS Ortodonti RSGM UNPAD dengan keluhan gigi depan tidak rapi dan gigi bawah terlihat lebih maju dibandingkan gigi rahang atas. Hasil diagnosis menunjukkan maloklusi dentoskeletal kelas III disertai asimetri wajah, palatum tinggi, pergeseran garis median rahang bawah, overjet terbalik, crossbite anterior, geligi berjejal, dan kurva Spee dalam. Pasien dirawat dengan straight wire appliance selama 1 tahun 8 bulan. Breket rahang atas dipasang terlebih dulu sampai overjet terkoreksi. Breket rahang bawah dipasang diikuti reduksi interproksimal. Pasien menggunakan elastik kelas III untuk koreksi relasi kaninus. Reduksi interproksimal menggunakan strip abrasif metal merupakan salah satu cara untuk mendapatkan ruangan pada kasus crowding ringan. Kombinasi reduksi interproksimal gigi anterior rahang bawah dan flaring gigi rahang atas, diikuti penggunaan elastik kelas III efektif mengoreksi overjet terbalik pada kasus maloklusi kelas III. Simpulan: Reduksi interproksimal dan elastik kelas III berhasil mengoreksi kasus maloklusi kelas III disertai crowding ringan dan masalah TSD.Kata kunci: Maloklusi, skeletal kelas III, crowding ringan, tooth size discrepancy (TSD), reduksi interproksimal. ABSTRACTIntroduction: Patient with dentoskeletal class III malocclusion, post-pubertal growth spurt, may be treated with orthodontic camouflage or orthognathic surgery. Camouflage treatment with good prognosis can have acceptable results if there is an only mild skeletal discrepancy. This report was aimed to investigate the effectiveness of camouflage treatment in dentoskeletal class III patient. Case report: A female patient, 16 y.o 7 months, came to Orthodontics Clinic of Universitas Padjadjaran Dental Hospital, complaining her anterior teeth looks crowded and her protrusive mandible. She was diagnosed with dentoskeletal class III malocclusion with asymmetrical face, high palate, midline shifting mandible, reverse overjet, crossbite anterior, crowding, and the deep curve of Spee. The patient was treated with straight wire appliance for one year and eight months. A lower bracket was bonded after anterior crossbite corrected, followed with interproximal reduction. Elastic class III was used to correct canine relationship. Interproximal reduction with metal abrasive is a common practice in orthodontic practice to gain spaces in mild crowding cases. Interproximal reduction in mandibular anterior teeth combined with anterior flaring of maxillary teeth, followed with elastic class III, effectively correct anterior crossbite in class III skeletal patient. Conclusion: Interproximal reduction and elastic class III effective to correct class III malocclusion with mild crowding and tooth size discrepancy problem.Keywords: Maloccusion, dentoskeletal class III, mild crowding, tooth size discrepancy (TSD), interproximal reduction.
