In cases requiring extraction of four first premolars, ensuring maintenance of adequate posterior anchorage and proper inclination of the teeth adjacent to the extraction sites during space closure can be difficult. The Invisalign G6 first premolar extraction solution has been developed to specifically address these problems. This case report describes the treatment of a 30-year-old woman whose main concerns were related to her protrusive and malaligned anterior teeth. Clinical findings revealed, among others, bimaxillary anterior protrusion and moderate-to-severe anterior crowding. A treatment approach involving extraction of the four first premolars was chosen, followed by orthodontic treatment with the Invisalign G6 first premolar extraction solution and Invisalign aligners. At the completion of 19.5 months of aligner treatment, the patient’s anterior teeth were retracted and uprighted, resulting in an improvement in her lip profile. Normal overjet and overbite were also achieved along with alleviation of the anterior crowding. The patient was extremely happy with the treatment results.

Ektopik kaninus seringkali dijumpai dalam praktek bidang ortodontik. Sebagian orang yang merasa terganggu dengan keadaan ini akan datang ke dokter gigi untuk mendapatkan perawatan. Perawatan ortodontik dilakukan untuk mengoreksi gigi yang ektopik dan memperbaiki fungsi estetik. Pada perawatan kasus ektopik kaninus ini, pencabutan gigi premolar kedua dilakukan karena tidak diperlukan perubahan profil. Teknik Begg merupakan teknik ortodontik yang menggunakan gaya ringan dengan kawat busur berpenampang bulat. Kawat busur akan bergerak bebas tanpa friksi dan menghasilkan gerak tipping mahkota gigi. Tujuan dari studi kasus ini adalah untuk memaparkan perawatan kaninus ektopik dalam tahapan teknik Begg. Pasien perempuan usia 19 tahun mengeluhkan gigi depan yang gingsul dan berjejal. Hasil pemeriksaan objektif menunjukkan ektopik pada gigi 13, 23 dan 33, overbite 5 mm, crowding anterior mandibula, dan crossbite anterior pada gigi 22 dan 33. Maloklusi kelas I skeletal dengan protrusif bimaksiler dan protrusif bidental, ektopik kaninus maksila bilateral, ektopik kaninus mandibula unilateral, deep bite, crowding anterior mandibula dan crossbite anterior. Dilakukan perawatan ortodontik cekat teknik Begg multiloop dengan pencabutan 15, 25, 36 dan 46. Sembilan bulan setelah perawatan, crossbite anterior, dan gigi 13, 23 dan 33 yang ektopik telah terkoreksi. Crowding anterior mandibula telah mengalami perbaikan dan perawatan masih berlanjut hingga saat ini. Perawatan teknik Begg multiloop dengan pencabutan gigi premolar kedua merupakan alternatif perawatan untuk koreksi ektopik kaninus, jika tidak diperlukan perubahan profil wajah pasien. ABSTRACT: Ectopic Canines Treatment Using Begg Technique with Second Premolar Extraction. Ectopic canines are often found in the field of orthodontic practice. People who are annoyed with this situation usually come to an orthodontist to seek for treatment. Orthodontic treatment has been performed to correct ectopic teeth and improve the function of aesthetics. In this case of ectopic canines, a second premolars tooth was extracted because profile changes are not required. Begg orthodontic technique is a technique that uses light forces by using round archwire. Archwire will move freely without friction and produce a tipping movement of dental crowns. A 19 year old female patient complained of ectopic and crowding anterior teeth. The objective examinations find ectopic of 13, 23 and 33, overbite: 5 mm, anterior mandibular crowding, and anterior crossbite of 22 and 33. Class I skeletal malocclusion, bimaxillar protrusive, bidental protrusive, bilateral ectopic canine maxilla and lateral ectopic canine mandibula, deep bite, anterior crowding and anterior crossbite. A fixed orthodontic treatment was performed by multiloop Begg technique with tooth extraction of 15, 25, 36, and 46. 9 months after treatment, anterior crossbite and ectopic 13, 23, 33 have been corrected by using multiloop Begg technique. Crowding in the lower arch has improved compared to initial condition and treatment still continues to this day. Multiloop Begg technique with second premolars extraction is an alternative treatment for ectopic canines correction if patient’s facial profile changes are not required.

BACKGROUND: After levelling and alignment in skeletal Class III patients with upper anterior crowding, the upper incisors usually have excessive proclination. In these cases, the upper incisors’ axial proclination need to be reduced to improve esthetics. CASE REPORT: This case report presents an invisible orthodontic treatment of a 24-year-old adult female patient with skeletal Class III relationship, anterior crossbite, proclined upper incisors, and reduced incisor showing. Patients denied extraction and interproximal reduction. With multi-slotted lingual brackets and straight archwires, we applied lingual crown torque to upper anterior teeth to reduce axial proclination. The resulting uprighted position of upper incisors led to increased incisor showing. A good smile and stable occlusion were obtained after 15 months of active treatment. CONCLUSION: The use of lingual brackets to apply lingual crown torque helps to reduce axial proclination and increasing upper incisor showing without interproximal reduction nor extraction in skeletal Class III patients with upper anterior crowding.

ABSTRACT Hypodontia is the most prevalent craniofacial malformation in mankind. It may present a wide variety of manifestations and, depending on the number and location of missing teeth, it may affect the esthetics, mastication, speech and occlusal balance. This paper discusses the therapeutic approaches to solve this condition, describing a case report with hypodontia of one mandibular lateral incisor, which treatment option included space closure at the region of hypodontia associated with composite resin restorations in the mandibular central incisors. The three-year follow-up after treatment revealed occlusal stability, adequate intercuspation in Class I relationship and excellent micro and macroesthetics.

Objectives The goal of this study was to analyze skeletal, dental, and soft tissue changes of patients treated with customized lingual systems and to evaluate the clinical effectiveness of miniscrew anchorage. Methods Nine upper first premolar extraction patients who were treated with customized lingual appliances were included in this study. Miniscrews were used for reinforcement of molar anchorage. Cephalometric films and study models were obtained before treatment (T1), after alignment (T2), and after treatment (T3). Treatment effects were analyzed by cephalometric radiographs and study models. Results The upper anterior teeth were retracted significantly at T2 and T3 (4.41 ± 4.14 mm and 5.51 ± 2.48 mm, respectively). During space closure, the upper first molars showed slight mesial movement (1.50 ± 1.97 mm). The intercanine width of the upper arch increased at T2 (1.59 ± 1.81 mm), but decreased at T3 (0.11 ± 1.00 mm). The sella-nasion-A, A-nasion-B, and mandibular plane angles were not significantly changed at T3. The upper lip showed continuous retraction at both T2 and T3 (1.40 ± 1.46 mm and 2.32 ± 2.48 mm, respectively). Conclusions By using miniscrew anchorage for lingual orthodontics, patients’ dental and soft tissue changes considerably improved and molar anchorage was reinforced.

Background: Patients with congenital absence of a mandibular lateral incisor are often found having difficulty in achieving adequate functional occlusion. It may affect esthetics, mastication, speech, and occlusal balance. Purpose: This paper reported an agenesis treatment of one mandibular lateral incisor case using a space closure method. Case: A twenty-three years old female patient with agenesis of tooth 42, mandibular anterior crowding, multiple diastema on mandibular anterior teeth, and skeletal class III malocclusion. Case Management: Space closure method was chosen to correct the agenesis by considering the class III skeletal malocclusion and multiple diastema condition. Conclusion: Space closure method treatment improved the patient’s facial and dental esthetics, and it provided a good functional occlusion, despite the absence of a mandibular lateral incisor, which generally impairs the adequate incisal guidance.

Gummy Smile

Inadequate posterior anchorage is a serious limitation for aligner treatment involving extraction of four first premolars. Inappropriate axial inclinations may compromise intermaxillary occlusion and stability. OrthoBoneScrew® (OBS) anchorage is designed to augment the Invisalign® clear aligner G6 solution to produce more predictable outcomes as illustrated by the current case report. An 18-year-old female presented with two chief complains: (1) Protrusive, incompetent lips, and (2) excessive gingival exposure when smiling (“gummy smile”). Clinical evaluation revealed bimaxillary protrusion, hypermentalis activity, anterior crowding, and excessive anterior axial inclinations, particularly of the lower incisors (116°). The American Board of Orthodontic (ABO) discrepancy index (DI) was 21. The treatment plan was extraction of all four first premolars, and clear aligner (Invisalign®) therapy anchored with four OBSs: Infra-zygomatic crest (IZC), and between the roots of the upper central and lateral incisors (Incisal) bilaterally. Eighteen months of initial treatment with 45 aligners retracted and intruded the anterior segments in both arches by closing the extraction spaces with supplemental anchorage provided by IZC and Incisal OBSs. The final series of 20 refinement aligners achieved an excellent outcome as evidenced by an ABO cast-radiograph evaluation (CRE) score of 10, and a pink and white (P&W) dental esthetic score of 3. Post-treatment analysis revealed multiple opportunities for improvement. The patient was well satisfied with the final outcome.

Bimaxillary Protrusion

Introduction: Esthetic is one of the outcome that is expected from orthodontic treatment. In orthodontic practice, lip protrusion has been observed with proclined upper and lower incisors in bimaxillary protrusion. Such lip protrusion has been shown to be reduced with backward movement of the anterior teeth, which often accompanies premolar extraction. Hence the aim of our study is to find out prevalence of lip competency among Nepalese Adolescents with different ethnic group of Kathmandu valley. Materials & Method: lt is a cross-sectional descriptive study. The study population included 14-18 year-old adolescents studying in high school of all three districts of Kathmandu Valley. An evaluation form was developed categorizing different levels of deep bite following WHO guidelines 1985 and accordingly data were recorded on it. Statistical Analysis: Data were analyzed with descriptive statistics using the Statistical Package for the Social Sciences (SPSS for Windows, Version 23) in which p-values were calculated by Pearson Chi-Square Tests. Result: Out of 935 screened students, 89.6% had competent lips and 10.4% had Incompetent lips. Female showed 91.9% of competent lips and 8.1% of incompetent lips. Male showed 87.8% of competent lips and 12.2% of incompetent lips. Among different ethnic group for lip competency, Advasi/Tharu showed 0.2%, Brahmin/chettri showed 61.6%, Dalit showed 0.6, janajati- Hi showed 35.8%, Madhesi showed 0.7%,Muslim showed 0.6% and others showed 0.3%. Among Brahmin/chettri 56.4% showed competent lips, 5.22% showed incompetent lips. However among Janajati-Hi 30.7% showed competent lips, 5.12% showed incompetent lips. Conclusion: The Prevalence of competent lips was 89.6% and incompetent lips was 10.4%. Among Genders both female and male showed higher percent of competent lips than incompetent lips. However competent lips were more associated with females. Among ethnic groups , Brahmin/chhetri have 61.6% of lip competency whereas Janajati-Hi have 35.8%. Rest of the ethnic group have less than 1% of lip competency. Among Brahmin/chettri 56.4% have competent lips, 5.22% have incompetent lips where as Janajati-Hi 30.7% have competent lips, 5.12% have incompetent lips.
