ABSTRACT Concurrent impaction and transposition of maxillary anterior teeth is uncommon and poses a challenge for dentists. Early diagnosis and management of eruption disturbances benefits esthetic and functional outcomes. This article describes the treatment of a teenager who had impactions of the left maxillary central incisor and canine as well as ipsilateral canine-lateral incisor transposition. Treatment alternatives and effective orthodontic techniques are delineated. To optimize the treatment results, the impacted maxillary canine was surgically exposed and orthodontically distalized with an innovative cantilever. Subsequently, the deeply impacted maxillary central incisor was uncovered and orthodontically mesialized into the arch. Finally, the displaced maxillary lateral incisor was brought into its normal position. The combined surgical-orthodontic approach resolved a difficult clinical issue and avoided additional restorations. An esthetic, functional outcome was achieved and satisfied the patient.

ABSTRACT This case report describes orthodontic space closure for managing an avulsed maxillary central incisor and a lateral incisor in a growing girl with a Class I deep bite malocclusion with moderate lower and mild upper crowding. The treatment approach moved a central incisor across the midline and substituted a lateral incisor for a central incisor, in combination with canine substitution. Veneers on all maxillary anterior teeth attained acceptable esthetics. The right central incisor was moved to serve as the avulsed left central incisor. The right lateral incisor was moved to the position of the right central incisor and restored. The canines on both sides were substituted as lateral incisors; the posterior occlusion was left in Class II. Mesialization of central and lateral incisors with prosthetic rehabilitation is an acceptable treatment option.

Descriptive studies of the deciduous dentition morphology have been presented as an inclusion in permanent dentition studies, the focus of archaeological populations or on specific traits within modern populations.The present study describes 25 morphological traits of deciduous dentition in two African American samples from Memphis, TN and Dallas, TX (N= 218), and a European American sample (N=100) from Cleveland, OH. These traits represent the most commonly used traits in population microevolution studies, describing various ancestral groups.Results indicate trait frequency variation between the two African American samples, as well as in comparison to European American samples. Traits varying in frequency between the two sample populations include maxillary lateral incisor shovel shape trait (69% vs. 46%), canine tuberculum dentale (40% vs. 22%), canine mesial ridge (3% vs. 7%), and maxillary posterior molar hypocone development (76% vs. 92%). Trait frequencies higher than found in previous studies include maxillary central incisor shovel shape trait (38%) and maxillary lateral incisor shovel shape trait (68%), canine tuberculum dentale (40%), maxillary molar complexity (20%), cusp six (33%) and seven (68%), and the Y-groove on the mandibular posterior molar (69%). Trait frequencies seen lower in previous studies include tuberculum dentale trait on both maxillary incisors (8% and 3%) and the hypocone development of the maxillary posterior molar (76%). The level of trait expression is informative when comparing populations, especially the molar traits. For example, Carabelli’s pit/fissure is the most common trait expression in African American samples, unlike European American samples.

Abstract Aim The purpose of this case report is to describe the combined surgical and orthodontic treatment of two cases with an impacted maxillary central incisor and canine in the same quadrant and to discuss the causal relationship between them. Background The most common causes of canine impactions are usually the result of one or more factors such as a long path of eruption, tooth size-arch length discrepancies, abnormal position of the tooth bud, prolonged retention or early loss of the deciduous canine, trauma, the presence of an alveolar cleft, ankylosis, cystic or neoplastic formation, dilaceration of the root, supernumerary teeth, and odontomas. Although impaction of the maxillary central incisor is almost as prevalent as impacted canines its etiology is different. The principal factors involved in causing the anomaly are supernumerary teeth, odontomas, and trauma. Reports Case #1 A 10.5-year-old girl in the early mixed dentition stage presented with a chief complaint of the appearance of her anterior teeth. She had a Class I skeletal pattern and a history of trauma to the maxillary central incisors at age five with premature exfoliation. Radiographs revealed an impacted upper right central incisor in the region of the nasal floor, delayed eruption of the maxillary permanent central incisor, and the adjacent lateral incisor was inclined toward the edentulous space. Treatment was done in two stages consisting of surgical exposure and traction of the impacted central incisor and fixed orthodontic treatment. Case #2 An 11.5-year-old girl presented for orthodontic treatment with the chief complaint of an unerupted tooth and the appearance of her upper anterior teeth. She was in the late mixed dentition period with a Class III skeletal pattern along with an anterior cross-bite with some maxillary transverse deficiency. The maxillary right canine and central incisor were absent, but the maxillary right deciduous canine was still present. Treatment included arch expansion followed by surgical exposure and traction of the impacted teeth and fixed orthodontic treatment. Summary This case report provides some evidence of a significant environmental influence of an impacted maxillary central incisor on the path of eruption of the ipsilateral maxillary canine. When an impacted maxillary central incisor exists, the maxillary lateral incisor's root might be positioned distally into the path of eruption of the maxillary canine preventing its normal eruption. Ongoing assessment and early intervention might help to prevent such adverse situations from occurring. Citation Bayram M, Özer M, Sener I.

Background & Objectives: Maxillary anterior tooth to tooth proportion has a special value in dental esthetics. This study aimed to assess the apparent proportion of maxillary anteriors and possible association with lower anterior facial height and malocclusion type. Materials & Methods: One-hundred and sixty samples with well aligned maxillary dentition were selected and the lower anterior facial height was measured with digital caliper. Molar relationship was examined and intraoral frontal photograph was taken for digital measurement of tooth proportion. The ratio of maxillary canine to lateral and lateral to central incisors were measured and compared between gender and the sides. These ratios were further compared among various malocclusion type using ANOVA and its association with lower anterior facial height was evaluated with Pearson’s correlation.Results: Most of the samples had Class I molar relationship (70%) followed by Class II (23%) and Class III (7%). The mean lower anterior facial height was 62.82mm and ratio of maxillary lateral to central incisor and canine to lateral incisor was 0.68 and 0.76 respectively. No statistically significant difference was found when the ratio was compared between the gender and the sides. These ratios were statistically different from the golden ratio and has no significant correlation with lower anterior facial height. These mean ratios were also found similar across the malocclusion type.Conclusion: Ratio of apparent dimension of maxillary canine to lateral incisor and lateral to central incisor was different from the golden ratio and showed no association with lower anterior facial height and malocclusion type.

Maxillary central incisor is the most commonly affected tooth during trauma followed by maxillary lateral incisor and mandibular incisors. Trauma to the anterior tooth requires urgent care because of the essentiality of preserving the natural tooth. When a complicated crown a fracture takes place, it necessitates endodontic treatment and restoration of a fractured crown segment with post in the canal. This case report describes a patient with a broken central incisor and treated with a Richmond crown.

AbstractAn altered facial appearance is more difficult to face, than problems related to ill-fitting denture or eating. The selection of maxillary anterior teeth for complete denture has long posed problem in clinical practice and a controversy about the best method to employ still exists. An attempt is made in the present study to clinically correlate the face form with maxillary central incisor tooth form in males and females of Davangere population. In 1914, Leon William's projected the “the form method” where he classified facial forms as square, tapering, and ovoid. Maxillary central incisors were selected according to the facial forms.Of total 100 subjects four different tooth forms and face forms were evaluated. They are: square, ovoid, square-tapered, tapered. No significant correlation existed between face form in male and females. Females exhibited greater correlation between face forms and inverted tooth form but that correlation is not sufficient to serve as a guide for selection of anterior teeth.

The present case report describes the orthodontic treatment of a patient with agenesis of maxillary left lateral incisor and Angle Class II, Division 1 malocclusion. The patient also presented with maxillary midline deviation and inclination of the occlusal plane in the anterior region. Treatment objectives were: correction of sagittal relationship between the maxilla and the mandible; correction of midline deviation, so as to cause maxillary and mandibular midlines to coincide; correction of overbite and leveling of the occlusal plane, so as to create ideal conditions for esthetic rehabilitation of anterior teeth. This case was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO) as a requirement for the title of certified by the BBO.

ABSTRACT Crown fractures of the anterior teeth are a common form of dental trauma mainly affecting children and adolescents. One of the options for managing crown fractures is the reattachment of the fractured fragment when the tooth fragment is available with minimal or no violation of the biological width. Reattachment of fractured fragments can provide good esthetics, as it maintains the tooth's original anatomic form, color, and surface texture. It also restores function and is a relatively simple procedure. This case report deals with the esthetic management of a crown-root fracture that was successfully treated with endodontic treatment followed by reattachment of fractured fragment with fiber post.

: In prosthodontics, esthetics a combination of the art and science. Patients requiring complete dentures usually expect comfort first, followed by harmonious appearance, and lastly efficiency. Therefore, the correct selection of the artificial teeth is essential for achieving a pleasant esthetic outcome. A number of soft tissue landmarks have been purported as useful for anterior tooth selection; but these are easily affected by several factors such as aging and the weight and build of the person. In the present study hard tissue landmarks like pterygomaxillary notches and maxillary arch width was presented as alternative anatomical landmark for anterior teeth selection. The aim of the study was to evaluate the hamular width and inter maxillary arch width which could be the guide for the selection ofartificial teeth for complete maxillary denture in the North-East Indian population.The study was conducted on 100 dentate individuals from the North Eastern Indian population, between the age group of 18- 30 years. All measurements were done with digital calliper on cast obtained after impression with irreversible hydrocolloid impression material.Pearson correlation analysis showed, statistically significant correlation between maxillary archwidth and central incisor width. The result was significant at p<0.05 but not high enough to be practically used. Correlation between hamular width and central incisor width was found to be insignificant. The value of R was 0.05435. The result was significant at p < 0.05. The maxillary arch width was in direct proportion to the maxillary central incisor width which meant that the increase of maxillary arch width,there was a corresponding increase of maxillary central incisor width. Significant correlation was found between maxillary arch width and central incisor width with p value=0132. The result was significant at p<0.05 but not high enough to be practically used. But In this study statistically insignificant correlation was found between hamular width and central incisor width.
