Abstract

Introduction: Transposition is an extreme and unique form of ectopic eruption. Orthodontic correction of transposed teeth in permanent dentition comprises the following treatment options: teeth alignment in the transposed position, orthodontic tooth movement into correct teeth order, or extraction on one of the transposed teeth followed by orthodontic correction. Case report: A 20-years-old male presented severe crowding and dental midline shift on both arches, followed by complete transposition of maxillary left canine – first premolar. A supernumerary tooth was also revealed between maxillary lateral and first premolar on the left side. The patient was treated with a pre-adjusted edgewise fixed appliance system. Extraction of supernumerary tooth and unilateral first premolars on the left side were performed to relieve crowding and to achieve stable occlusion. Improvement of smile aesthetic, correction of midline shift, and also an ideal class I of canine and posterior interdigitation were achieved after 22 months of treatment. Conclusion: Definitive treatment of transposition depends on the occlusion, degree of crowding, aesthetics, root position of the transposed teeth, and specific needs of the patient. Care must be taken to prevent midline shift and development of arch asymmetry during orthodontic correction of transposition involving unilateral extraction.

Abstract

Introduction: Based on Indonesia Basic Health Research in 2018, it is known that 47% of Lampung people experience tooth decay and only 51% of them regularly go to the dentist. The need for orthodontic treatment is quite high among students. Epidemiological studies in Japan show that around 40% of teenagers aged 15-18 years need orthodontic treatment, 27%-36% in England aged 10-15 years, while in South Jakarta (2004) is 48.5%. Brook and Shaw introduced the Index of Orthodontic Treatment Need (IOTN), to assess the need for orthodontic treatment in England. IOTN has been applied by Agusni, T to measure the treatment needs of urban and rural children in Surabaya. Objective: Aims to determine the perceptions of elementary school students in Lampung regarding Malocclusion and the need for Orthodontic treatment. Method: A cross-sectional study was conducted in May 2023, carried out on students at public Elementary School Bumi Agung who met the inclusion criteria, namely aged 9-13 years, had never and were not currently undergoing orthodontic treatment, and were willing to take part in the research. 130 people were selected using a purposive sampling technique. Questionnaires were used to obtain sociodemographic data and general knowledge about Dental and Oral Health and Malocclusion. Assessment of the need for orthodontic treatment was carried out using the AC IOTN by the subject and operator. Results: 90% of students answered the questionnaire correctly, and 42% of students needed orthodontic treatment. A Pearson Chi-Square analysis test was carried out and found that there was a statistical difference in the perception of the need for orthodontic treatment by students and operators (p-value <0.05). Conclusion: Students at SDN Bumi Agung, Kalianda, Lampung, have very good general knowledge about Dental and Oral Health and Malocclusion. However, this is unsubstantiated by the perception of the need for orthodontic treatment.

Abstract

Background: Malocclusion is the irregularity of teeth, considered as an oral health problem resulting from various etiological factors, causing esthetic dissatisfaction to functional impairment. Malocclusions must be fixed by orthodontic treatment. Achieving proper incisor inclination and angulation is essential for orthodontic treatment stability and facial harmony. However, limited evidence exists regarding post-treatment incisor positioning in Class I skeletal malocclusion patients within the Indonesian population. Objective: This study aimed to analyze the post-treatment inclination and angulation of maxillary and mandibular incisors in Class I skeletal malocclusion patients and to evaluate whether these parameters fall within established cephalometric norms. Methods: A descriptive cross-sectional analysis was conducted using secondary cephalometric data from 96 post-treatment medical records. Incisor inclination was measured using U1–SN, U1–PP, L1–MP, and IMPA angles, while angulation was assessed for upper and lower central incisors. Results: The mean upper incisor angles were 106° (U1-SN) and 115° (U1-PP), and the lower incisor angles were 94° (L1-MP) and 96° (IMPA). The mean angulation of individual incisors was approximately 89–91° for both upper and lower central incisors. Conclusion: Pre-adjusted bracket systems used in the study effectively guide incisors toward favorable positioning within normal ranges, with minor variations such as the IMPA angle, supporting both functional and esthetic outcomes.This study took the initiative to describe both post-treatment upper and lower incisor position in Indonesian orthodontic patients.
