[An attempt at assessment of the numerical grading of success concerning diagnosis, therapy and prognosis in tooth alignment and malocclusion].

An attempt to assess the numerical grading of success with regard to the diagnosis, therapy and prognosis of anomalies of tooth alignment and occlusal position. Classifications according to Korkhaus, Angle and Eismann were evaluated using the original and final models of 42 patients who had been very co-operative. The importance and applicability in therapy and prognosis are assessed.

Transposition of mesial and distal aspects of maxillary first molars: case report.

Congenital absence of one or more teeth, hypodontia, is the most common developmental anomaly and is often accompanied by the presence of other tooth anomalies. In this case two Japanese sisters have several congenitally missing primary and permanent teeth and morphological abnormalities of maxillary first molars. One sister has transposition of mesial and distal aspects of a maxillary first molar, whose cusps display a normal shape. Another sister has maxillary first molars, which look like maxillary second molars. Mesio-distally shift of teeth is a very rare anomaly making this particular case important to analyze the teeth formation and development.

Congenitally missing maxillary lateral incisors and orthodontic treatment considerations for the single-tooth implant.

Implant restorations have become a primary treatment option for the replacement of congenitally missing lateral incisors. The central incisor and canine often erupt in less than optimal positions adjacent to the edentulous lateral incisor space, and therefore preprosthetic orthodontic treatment is frequently required. Derotation of the central incisor and canine, space closure and correction of root proximities may be required to create appropriate space in which to place the implant and achieve an esthetic restoration. This paper discusses aspects of preprosthetic orthodontic diagnosis and treatment that need to be considered with implant restorations.

Recurrent infection of a complex odontoma following eruption in the mouth.

Odontomas are the most common odontogenic tumors, and are classified as either compound or complex lesions. Although its underlying etiology remains unclear, a number of factors appear to be involved (e.g., prior trauma). The lesions are generally diagnosed in the second decade of life, often in the context of routine dental X-ray examinations. A complex odontoma is described in a 22-year-old woman referring discomfort due to overinfection following its aperture into the oral cavity in the distal alveolar region of 2.6. Initial treatment consisted of antibiotics and antiinflammatory drugs. Computed axial tomography revealed a solid, irregular mass in the distal zone of the left maxilla, imprinting upon the region of the maxillary sinus on the same side. Surgical resection was performed, raising the alveolar mucosa and upper left vestibular fundus. The surgical piece contained the amorphous adenoma mass and the tooth 2.7.

Maxillary canine transpositions in two brothers and one sister: associated dental anomalies and genetic basis.

Transposition is an uncommon dental anomaly involving positional interchange of two teeth. The maxillary canine is the tooth more frequently transposed in man. Maxillary canine-first premolar appears to be the most common type of tooth transposition, followed by maxillary canine-lateral incisor transposition. Maxillary canine transpositions are frequently associated with other dental abnormalities such as agenesis and pegshaped incisors. This report describes the presence of transposed canines in one sister and two brothers. The female showed bilateral maxillary canine-first premolar transposition with the left canine fully mesial to its neighboring first premolar, and the right canine blocked-out facially between the first and second premolar. One of the brothers showed full maxillary left canine-lateral incisor transposition. The other brother showed maxillary canine-first premolar transposition and agenesis of maxillary lateral incisors, with the left canine blocked-out facially between the first and second premolar. Findings from this case report and other previously published cases provide strong evidence that maxillary canine transpositions are a disturbance of tooth order and eruptive position resulting from genetic influences within a multifactorial inheritance model.

Mandibular lateral incisor-canine transposition (Mn.12.C): a case report.

Tooth transposition is a rare developmental anomaly of the teeth characterized by positional interchange of permanent tooth leading to disintegration in the alignment in the affected segment, shifting of midline and malocclusion of teeth. This article reports a rare case of Mn.12.C anomaly affecting right mandibular arch of a (11 year old) female child causing shifting of midline and crowding.

Inverted central incisor--a case report.

An unusual case of inverted central incisor in a nine year old girl is reported here. The case was diagnosed as an infected dentigerous cyst. The unerupted central incisor was placed inverted almost near the ethmoid bone. The cyst was enucleated successfully.
