Esthetic improvements through systematic diagnosis and treatment procedures in patients with unesthetic maxillary anterior teeth proportion after orthodontic treatment: Case report / 대한치과보철학회지

The treatment of areas demanding esthetic requirements, such as maxillary anterior teeth, should take into account the achievement of a healthy, harmonious to the surrounding tissue, and an attractive smile line. In this case report, smile line, soft tissue and hard tissue morphology, and the anatomy and proportion of the tooth, must be considered. In patients with unesthetic maxillary anterior ratio due to inadequate gingival contour and diastema caused by peg lateralis, it would be challenging to achieve an esthetic restoration by orthodontic treatment alone. In such case, after orthodontic treatment, dento-gingivo-facial compositional diagnosis and analysis, followed by gingivectomy and prosthodontic restoration is needed to improve the interdental mesial/distal, width/length ratio to achieve a satisfactory esthetic result. In addition, when improving the tooth proportion of peg lateralis by prosthodontic treatment, Porcelain laminate veneer (PLV), which results in less tooth structure loss, reproduction of similar shade to that of the proximal tooth and high transparency, is recommended. This case report demonstrates esthetic improvements by prosthodontic restoration through systematic diagnosis and treatment procedure in patients with unesthetic maxillary anterior proportion after orthodontic treatment due to peg lateralis by means of two female patients aged twenty years old.

Geometrical analysis on the dentofacial composition of korean beautiful woman / 대한치과보철학회지

STATEMENT OF PROBLEM: The meaning of the beauty has a little different nature according to a time, culture, and nation. PURPOSE: This study was undertaken to estimate the geometric esthetic criteria for Korean woman by analysis of facial photograph in a smiling. MATERIAL AND METHODS: The facial photographs of 678 Korean beautiful woman were collected from Miss Korea candidates(from 1971 to 2003 year). The dento-facial composition was measured and analyzed geometrically on computer monitor using Adobe. Photoshop. 7.0. The statistical significance of the differences among the 4 decade groups was estimated by a chi2 test. RESULT: The Korean beautiful woman showed the geometric characteristics such as the 'coincidence'(83.0%) between facial midline and dental midline, the 'normal'(96.9%) alignment and arrangement of upper anterior teeth, the 'average'(79.1%) position and 'upward'(53.4%) curvature of upper lip, the 'parallel'(85.7%) relationship between the lower lip and upper anterior incisal curvature, the 'touching'(49.9%) and 'not-touching'(44.8%) relationship between upper anterior incisor and lower lip, the 'first premolar'(54.1%) and 'second premolar'(38.9%) displayed in a smile, and the 'symmetry'(89.4%) of smile. There was statistical significance among the 4 decades in the respect of the upper lip curvature, the relationship between upper anterior incisor and lower lip, and the most posterior teeth displayed in a smile (p<0.05). CONCLUSION: The Korean beautiful woman showed similar results to the western esthetic criteria in the some respects and the tendency that the Korean woman had more active smiling recently.
