“…This fact justified the changes that occurred in relation to the distance of Line E from the lower part of the lower lip. This was in agreement with other studies that evaluated the tegumentary effects of mandibular protraction -similar to the MPA, which had significant effect on improvement of the profile [13][14][15] .…”

“…Several authors have studied the effects of Class II treatment by means of cephalometric evaluation 13,14 , including cephalometric changes in MPA treatment 3,13,15 but there is a scarcity of studies in the literature assessing the effects of mandibular protraction by the Ricketts Analysis. Those that used Ricketts, only evaluated alterations in the profile, mesialization of the first molars, and verified the upper airway space [16][17][18] .…”

Objective This study was designed to evaluate the skeletal, dental and soft tissue effects of mandibular deficiency treatment with the mandibular protraction appliance (MPA) using 12 factors of the Ricketts analysis. Material and method This cross-sectional retrospective study sample consisted of a group (n = 27), with Class II malocclusion, convex facial profile, increased horizontal trespass and mandibular deficiency, with initial mean age of 12.27 and final of 15.18 years, treated with fixed appliance combined with the MPA, in an average time of 2.9 years. Initial and final radiographs were investigated using Ricketts analysis. The dependent t-test was used to compare the initial and final phases of the MPA group, with a significance level of 5%. Result Statistically significant differences were observed for dental changes such as retrusion (p=0.000) and palatal inclination of the maxillary incisors (p=0.000); protrusion (p=0.000) and buccal inclination of the mandibular incisors (p=0.000); increased interincisal angle (p=0.002) and improved molar ratio (p=0.003). There was also a restriction of the anterior displacement of the maxilla (p=0.000) and a decrease in the mandibular plane angle (p=0.024). The variable inferior labial protrusion with significance (p=0.000), reiterated the improvement in the profile. Conclusion The effects of MPA on correction of malocclusion Class II, verified by Ricketts analysis occurred predominantly by dentoalveolar changes, decrease in the Mandibular Plane Angle, and restriction of anterior displacement of the maxilla, which contributed to the improvement in the patient's profile.

“…This disproportion is usually due to mandibular retrusion [12] . In growing patient, growth modification by functional appliances is a well-known strategy to reduce mandibular retrognathism by accelerating the development of the mandible [13] . Many functional appliances are available for achieving this, but clinicians usually seek for simple and effective ones.…”

Aim: The aim of the present study was to evaluate the skeletal and dento-alveolar effects of the Rick-A-Nator appliance in the treatment of growing patients with skeletal Class II malocclusion due to retrusive mandible. Methods: 13 Class II growing patients with mandibular retrusion and between the ages of 9 years and 12 years were selected to be included in this study. Control group for the treated group was generated from growth data of untreated Class II subjects. Pre-treatment and post-treatment lateral cephalometric radiographs were traced and analyzed. Changes in the treated group were compared to those in the control group. Results: The mandibular length was highly significantly increased by 2.44 mm. The mandibular incisors were proclined by distance of 4.54 mm. The overjet was highly significantly reduced by 4.25 mm. The molar relation was significantly corrected by 3.62 mm. While the overbite was reduced from a mean of 75.43% before treatment to a mean of 21.16% after treatment. Conclusions: The Rick-A-Nator appliance was effective in treatment of Class II malocclusion with deficient mandible. Significant reduction of the overjet and the overbite were associated with the Rick-A-Nator treatment.

“…Salah satu alat fungsional yang sering digunakan dalam merawat klas II divisi 1 adalah Bionator. 6 Bionator pertama kali dikembangkan oleh Wihelm Balter tahun 1964 dan merupakan alat terbuat dari akrilik dengan kawat pada bagian palatinal dan vestibulum. Alat ini bekerja untuk memajukan mandibula, mengokoreksi overbite, mengatur erupsi gigi dan memperbaiki profil pasien.…”

Maloklusi Angle klas II divisi 1 mempunyai ciri tonjol mesiobukal molar pertama atas beroklusi dengan interdental premolar kedua dan molar pertama bawah, jarak gigit yang besar, lengkung gigi sempit dan profil cembung. Bionator pertama kali diperkenalkan oleh Balter dan merupakan alat ortodontik myofungsional yang digunakan untuk merawat diskrepansi rahang. Tujuan pemaparan kasus adalah menyajikan kemajuan kasus maloklusi Angle Klas II divisi 1 disertai diskrepansi rahang menggunakan alat myofunctional bionator. Seorang perempuan berusia 13 tahun mengeluhkan gigi depan atas maju. Diagnosis pasien maloklusi Angle klas II divisi 1, hubungan skeletal klas II dengan protrusif maksila dan retrusif mandibula, protrusif insisivus atas disertai palatal bite, cross bite posterior, jarak gigit 11 mm, tumpang gigit 5,25 mm, SNA 84°, SNB 76°. Pasien dirawat menggunakan alat myofungsional bionator. Hasil perawatan setelah satu tahun overjet menjadi 6,25 mm dan SNB 78°. Kesimpulannya adalah alat myofungsional bionator efektif untuk merawat maloklusi Angle Klas II divisi 1 yang disertai diskrepansi rahang.
