ABSTRACT The case describes the interdisciplinary treatment of a 23-year-old woman with a Class III malocclusion, missing an upper right lateral incisor, abrasion of the maxillary incisal edges, anterior gingival margin discrepancies, and gingival recession. Initially, the patient was treated with fixed appliances combined with orthognathic surgery. The extraction of the upper left lateral incisor and bilateral canine substitution plan was chosen. At the end of the surgical and orthodontic treatment, the restorative treatment with six veneers was accomplished to improve smile esthetics. Despite the missing lateral incisors, the patient showed a natural, good-looking final result. A symmetric incisal plane was established, a functional occlusion with average vertical and horizontal overlap was set, and the bone scallop and consequently the gingival margins were leveled. The interdisciplinary approach hid all of the initial esthetic defects of the case. The result highlights how to obtain a remarkable improvement of the smile outcome with a well-functioning masticatory system.

Congenitally Missing

Background: Patients presenting with congenitally missing teeth are relatively common and the aim of the dental team is to create a functional, healthy, and aesthetically acceptable dentition. The consequences of missing teeth include an abnormal occlusion or an altered facial appearance which may lead to psychological distress in some patients.Methods: The present case report describes a 23 year old patient with non-syndromic, congenitally missing permanent teeth (CMMPT). Clinical and radiographic examinations revealed agenesis of eight permanent teeth including the third molars. Following interdisciplinary treatment planning, the patient was treated with mechano therapy to correct a class III incisal relationship by space closure in the lower arch. In the upper arch, the right canine was substituted for a missing lateral incisor and space was opened for a prosthetic left lateral incisor (a mini implant).Results: Active orthodontic treatment was completed in 19 months. The management of CMMPT requires an interdisciplinary approach to achieve improved occlusal function and aesthetics.Conclusion: A combined orthodontic-implant-prosthodontic treatment approach can achieve an improved functioning occlusion, and favorable aesthetics.Bangladesh Journal of Medical Science Vol.16(3) 2017 p.467-473

Common Etiology ◽  
Maxillary Lateral Incisor

Anterior spacing is a common esthetic problem of patient during dental consultation. The most common etiology include tooth size and arch length discrepancy. Maxillary lateral incisors vary in form more than any other tooth in the mouth except the third molars. Microdontia is a condition where the teeth are smaller than the normal size. Microdontia of maxillary lateral incisor is called as “peg lateral”, that exhibit converging mesial and distal surfaces of crown forming a cone like shape. A carefully documented diagnosis and treatment plan are essential if the clinician is to apply the most effective approach to address the patient’s needs. A patient sometimes requires a multidisciplinary approach to correct the esthetics and to improve the occlusion. This case report describes the management of an adult female patient with a proclined upper anterior teeth, upper anterior spacing, deep bite and peg shaped upper right lateral incisor tooth through orthodontic and restorative treatment approach.

Maxillary Lateral Incisor

The maxillary permanent canine is the tooth most frequently involved, which is often transposed with the first premolar followed by transposition between the maxillary permanent canine and maxillary lateral incisor. This study describes the correction of complete transposition of the maxillary left first premolar with impacted permanent maxillary left canine and congenital missing maxillary lateral incisor. The current case report describes a multidisciplinary approach for the alignment of impacted and transposed teeth with surgical exposure of impacted maxillary canine and restorative treatment of transposed maxillary left first premolar. The satisfactory results were achieved with maximum three-dimensional control of tooth movement and without any iatrogenic damage.

ABSTRACT Objective: To evaluate stresses on maxillary teeth during alignment of a palatally impacted canine (PIC) under different loading conditions with forces applied in vertical and buccal directions. Materials and Methods: A three-dimensional finite element model of the maxilla was developed from a cone beam computed tomographic scan of a patient with a left PIC. Traction was simulated under different setups: (1) palatal spring extending from a transpalatal bar (TPB) anchored on the first molars (M1) and alternatively combined with different archwires (0.016 × 0.022-inch; 0.018 × 0.025-inch) with and without engaging second molars and (2) a buccal force against 0.018-inch, 0.016 × 0.022-inch, and 0.018 × 0.025-inch archwires with and without engaging the left lateral incisor (I2). Results: Without fixed appliances, stresses were assumed by M1; with fixed appliances, stresses were distributed on all teeth, decreasing mesially toward the midline. Direct buccal pull exerted most stress on neighboring I2 (19–20% with different wire sizes) and first premolar (12–17%), decreasing distally, along a similar pattern with different archwire sizes. When I2 was bypassed, stresses on adjacent teeth increased only by 3–6%. Higher stresses occurred with the lighter round wire. Conclusions: This first research on stresses on adjacent teeth during PIC traction provided needed quantitative data on the pattern of stress generation, suggesting the following clinical implications: use of distal-vertical pull from posterior anchorage (TPB) as initial movement and when using a buccal force, bypassing the lateral incisor and using heavier wires that would minimize side effects.

Sculpture is an artistic practice that involves material, three-dimensional, and generally static objects, whereas cinema produces immaterial, two-dimensional, kinetic images. These differences are the basis for a range of magical, mystical and phenomenological interactions between the two media. Sculptures are literally brought to life on the silver screen, while living people are turned into, or trapped inside, statuary. Sculpture motivates cinematic movement and film makes manifest the durational properties of sculptural space. This book will examine key sculptural motifs and cinematic sculpture in film history through seven chapters and an extensive reference gallery, dealing with the transformation skills of "cinemagician" Georges Méliès, the experimental art documentaries of Carl Theodor Dreyer and Henri Alekan, the statuary metaphors of modernist cinema, the mythological living statues of the peplum genre, and contemporary art practices in which film—as material and apparatus—is used as sculptural medium. The book’s broad scope and interdisciplinary approach is sure to interest scholars, amateurs and students alike.

Abstract Background Class III malocclusion is associated with high sexual dimorphism, especially in individuals older than 13 years of age, with significant differences in growth between males and females during the pubertal and postpubertal stages, and in adulthood. The aim of this research was to examine differences between males and females in long-term stability (10 years) of treatment for skeletal Class III malocclusion. Methods Thirty patients (15 males and 15 females) with skeletal Class III malocclusion, who had been treated with rapid maxillary expansion (RME) combined with face mask protraction followed by fixed appliances, were selected sequentially. Thirty patients (15 males and 15 females) with skeletal Class I and mesofacial patterns treated only with fixed appliances for dental problems served as the control group. Differences between groups and sexes were evaluated using lateral cephalograms taken at the start of treatment (T0), immediately after the end of treatment (T1), and after 10 years (T2). The long-term treatment success rate was calculated. Results Ten years after Class III treatment, overjet and overbite relapse occurred similarly in females (− 0.68 ± 0.7 mm; − 0.38 ± 0.75 mm, respectively) and males (− 1.09 ± 1.47 mm; − 0.64 ± 0.9 mm, respectively); the ANB angle and Wits appraisal became significantly more negative in males (− 1.37 ± 1.06°; − 2.7 ± 2.53 mm) than in females (− 0.18 ± 1.26°; − 0.46 ± 1.94 mm). The success rate was 73.3% in males and 80% in females. Conclusions Significant differences in the long-term stability of Class III treatment outcomes have been found between males and females, with a larger skeletal Class III relapse and lower long-term success rates in males.
