Objective. In this study we tried to notice the differences in the number and type of occlusal contacts present in patients with Angle Class I and Class-II malocclusions. Materials and methods. For this study were examined 30 patients with Angle Class I and Class-II malocclusions. Identification of the number and type of occlusal contacts was made both clinically and with the help of study casts mounted in an semiadjustable articulator. Results and discussion. In the Angle Class I malocclusion average total number of occlusal contacts was 36.93 and in Angle Class-II malocclusion was 31.46 contacts. Most occlusal contacts identified were side cusp – side fossa type. Following statistical analysis we did not fi nd significant differences between the two classes of malocclusions, in terms of total number of occlusal contacts. Conclusions. The total number of occlusal contacts does not differ depending on the malocclusion class, but there are differences between the number of contacts occurring within certain groups of posterior teeth. In order to have findings with practical application it is necessary to carry out more studies on the type and number of occlusal contacts that may occur in individuals with malocclusions.

Objective. In this study we tried to identify the premature occlusal contacts that are present in patients with Angle Class I and Class II malocclusions. Materials and method. For this study 60 patients with Angle Class I and Class II malocclusions were examined. Identification of premature occlusal contacts was made both clinically and with the help of study casts mounted in an adjustable articulator. Results and discussion. Based on the statistical analysis made in this study we noticed that for patients with Angle Class I malocclusion, premature occlusal contacts from protrusion on the working side are more common, they are present in 15 patients, than to those with Angle Class II malocclusion where they were identified in 13 patients. In right laterotrusive edge to edge position we noticed that there are premature occlusal contacts on the working side in 43.3% of patients with Angle Class I malocclusion, and 50% of patients with Angle Class II malocclusion. Conclusions. In protrusive and laterotrusive edge to edge position there are premature occlusal contacts both at Angle Class I malocclusion, and in Angle Class II malocclusion patients. For practical conclusions, it is necessary to carry out more studies on the identification of occlusal premature contacts, which may occur in people with malocclusion.

ABSTRACT Objective: To compare self-esteem scores in 12 to 16-year-old adolescents with different Angle malocclusion types in a Peruvian sample. Material and Methods: A cross-sectional study was conducted in a sample of 276 adolescents (159, 52 and 65 with Angle Class I, II and III malocclusions, respectively) from Trujillo, Peru. Participants were asked to complete the Rosenberg Self-Esteem Scale (RSES) and were also clinically examined, so as to have Angle malocclusion classification determined. Analysis of covariance (ANCOVA) was used to compare RSES scores among adolescents with Class I, II and III malocclusions, with participants' demographic factors being controlled. Results: Mean RSES scores for adolescents with Class I, II and III malocclusions were 20.47 ± 3.96, 21.96 ± 3.27 and 21.26 ± 4.81, respectively. The ANCOVA test showed that adolescents with Class II malocclusion had a significantly higher RSES score than those with Class I malocclusion, but there were no differences between other malocclusion groups. Supplemental analysis suggested that only those with Class II, Division 2 malocclusion might have greater self-esteem when compared to adolescents with Class I malocclusion. Conclusion: This study shows that, in general, self-esteem did not vary according to adolescents' malocclusion in the sample studied. Surprisingly, only adolescents with Class II malocclusion, particularly Class II, Division 2, reported better self-esteem than those with Class I malocclusion. A more detailed analysis assessing the impact of anterior occlusal features should be conducted.

Abstract Malocclusions with a hyperdivergent vertical facial pattern are often difficult to treat without a combined surgical/orthodontic approach. The aim of this article is to describe a nonsurgical approach to the treatment of a high-angle Class II malocclusion in a growing patient. Some fundamental aspects, such as correct diagnosis, treatment timing, favorable mandibular growth pattern, and patient compliance, proved to be critical to correct the severe dentoskeletal disharmony.

Facial Esthetics

Angle Class II malocclusion associated with anterior open bite in adult patients demands a carefully elaborated orthodontic planning, aiming at restoring not only harmonious dental and facial esthetics, but also a balanced masticatory function. Orthognathic surgery or permanent teeth extraction are often the choice of treatment, therefore, treatment decision is related to all dental, skeletal and functional aspects. The present report discusses orthodontic compensation carried out by means of upper premolar extraction performed to correct the Class II canine relationship and, consequently, the anterior open bite, accepting that the upper incisors be retroclined. This clinical case was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO) as part of the requirements for obtaining the BBO Certification.

Latar Belakang: ketidakharmonisan ukuran rahang dengan gigi merupakan salah satu bentuk etiologi maloklusi yang diturunkan dan akan mempengaruhi susunan dan posisi gigi di dalam rahang. Impaksi gigi seperti molar ketiga atau gigi kaninus sering kita temui akibat tidak adanya ruang untuk gigi tersebut erupsi dan menyusun diri di dalam lengkung yang baik. Gigi kaninus memiliki peran penting di dalam mulut, selain untuk mastikasi, gigi ini juga memiliki peran menentukan dalam estetika susunan gigi. Senyum yang menarik tidak akan didapatkan tanpa adanya gigi kaninus di dalam lengkung. Kasus impaksi kaninus dapat dirawat menggunakan teknik Begg dengan proses windowing yang dilakukan oleh ahli bedah mulut. Tujuan: membantu erupsi gigi kaninus dengan bantuan alat orto cekat teknik Begg. Kasus: laki-laki 19 tahun mengeluhkan gigi depan rahang atas protusif langit-langit tergigit oleh gigi depan rahang bawah. Diagnosis: maloklusi Angle kelas II dengan hubungan skeletal kelas I disertai kondisi berjejal di daerah anterior dan gigitan dalam. Perawatan: menggunakan alat cekat teknik Begg dan windowing dengan pencabutan dua premolar pertama rahang atas serta prosedur windo. Kesimpulan: hasil menunjukkan gigi kaninus kiri rahang atas dapat erupsi dengan baik dan bisa diposisikan ke dalam lengkung dalam 5 bulan. Background: Discrepancy in size between jaw and teeth is one of the etiology factor of malocclusion that genetically inherited and will affect teeth allignment and position within the jaw. Third molar and canine impaction frequently found because there is not enough space for theme to erupt and align themselfes in a good alignment. Canine have an important role in mastication as it is in facial aesthetic. Canine impaction can be treated with Begg technique and windowing process performed by oral surgeon. Purpose: to help impacted canine to erupt using fixed Begg appliance technique and windowing process. Case: 19 years old man complained of crowded front teeth. Diagnosis: malocclusion Angle class II, skeletal class I with crowding and deepbite on anterior segment. Treatment: using the Begg fixed appliance and windowing techniques with the extraction of two maxillary first premolars. Conclusion: the result showed that maxillary right canine erupted and can be adjusted within the line of occlusion in 5 months.
