INTRODUCTION A canted occlusal plane presents an unesthetic element of the smile. The correction of this asymmetry has been typically considered difficult by orthodontists, as it requires complex mechanics and may sometimes even require orthognathic surgery. OBJECTIVE This paper outlines the case of a 29-year-old woman with Class II malocclusion, pronounced midline deviation and accentuated o...

The aim of this study was to determine the pre- and post-treatment width changes in the canine, premolar and molar regions in subjects treated with extraction of four first premolars, non-extraction, and non-extraction with rapid maxillary expansion (RME). Pre- and post-treatment orthodontic study models of 60 females (13.83 +/- 2.77 years) and 24 males (14.33 +/- 2.67 years) who underwent comp...

CE Incisor malocclusion is common in rabbits. If this condition occurs as an isolated entity at an early age, it probably has a genetic origin. Incisor malocclusion in older animals is usually secondary to, or occurs concomitantly with, premolar–molar malocclusion. Therefore, patients with incisor malocclusion should always receive a comprehensive oral examination. Incisor–premolar–molar malocc...

PURPOSE Patterns of von Mises stress values surrounding implants supporting fixed prostheses in the posterior edentulous maxilla were evaluated using 3-dimensional finite element analysis. MATERIALS AND METHODS Implants were placed in maxillary bone in 2 different configurations. In the first configuration, implants were placed in the first premolar, second premolar, and second molar regions;...

Disturbances involving abnormalities in tooth eruption are named ectopia. Transmigration is the name assigned to ectopia in the presence of teeth in areas distant from the alveolar process. Initial angulation of the tooth bud of the second premolar and premature loss of permanent mandibular 1st molars can influence the distal migration of the second premolar. Some studies have observed that ect...

OBJECTIVE To elucidate relationships between the dental roots and surrounding tissues in order to prevent complications after placement of a miniscrew. MATERIALS AND METHODS Twenty human mandibles and maxillas were used for this study. In the 200 sections of each mandible and maxilla, nine items were measured to investigate the relationships between the dental roots. RESULTS The interroot d...

The aim of this study was to compare smile attractiveness between one, three, and four premolar extraction protocols in patients with Class II division 1 subdivision malocclusions and to analyse the aesthetic influence of buccal and posterior corridor widths on smile attractiveness. The sample consisted of posed smile photographs obtained from 66 subjects, divided into three groups according to...

Introdouction: Cone-beam computed tomography (CBCT) scanning is a technological innovation developed in recent years with potential use in oral surgery and many other dental procedures. The aim of this study is to determine the maxillary sinus mucosal thickening in the maxillary premolar-molar area using the CBCT technique. Materials and methods: In this retrospective study, a total of 105 c...
