Background:
Esthetics is the primary consideration for patients looking for prosthetic treatment. Determining the facial types of Thai populations is important because most studies conducted in Caucasian populations mention their facial types, and describe the gender comparisons, and GP of the teeth.
Objectives:
This study compared facial proportions, analyzed the maxillary anterior teeth proportions and determined the relationships between teeth with facial measurements using the Golden Proportion (GP) and Golden Standard (GS) in a Thai population.
Methods:
A total of 200 students (18-35 years) with well-aligned maxillary anterior teeth participated in this study. Face heights and widths were measured from the face using digital calipers and faces were classified as narrow, average, and broad. Teeth and face proportions were compared with GP and GS. One-way ANOVA was performed to compare maxillary anterior teeth proportions and facial proportions with different face types (α= 0.05). Pearson’s correlation was used (α= 0.05) to determine the correlation between facial proportion and teeth dimension among different facial types.
Results:
The findings showed 82.50% narrow face, 13.50% average, and 4% broad face among Thai subjects. No GP or GS was found in the face and anterior teeth, but teeth and face proportions other than GP and GS were found. No significant correlation was found between the Width of the Central Incisor (WCI) with interpupillary distance and alar width.
Conclusion:
In this study, the GP was not found in the facial and teeth proportion. The data obtained from this study may help to provide guidelines for prosthetic and orthodontic management and help to select the proper size and form of the maxillary anterior teeth to achieve proper esthetic outcomes in the Thai population.
Soft palate tumors pose the challenge during reconstructive and rehabilitating procedures. Surgical resection of these tumors leads to velopharyngeal insufficiency (VPI). The primary effects of VPI are hypernasality and air-flow escape, while the secondary effects are abnormalities in speech articulation. Surgical revision along with speech therapy is a common approach to the treatment of VPI. Prosthetic management by means of speech aid prosthesis helps to reduce resonance, nasal emission and consonants errors. This clinical report describes the different stages of rehabilitation of velopharyngeal insufficiency defect following resection of malignant melanoma of left posterior alveolar ridge and soft palate. The speech aid prosthesis helped to rehabilitate the velopharyngeal insufficiency defect and aided in the diagnosis of extent of speech function improvement by perceptual and objective methods.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
