Abstract

Aim

This study was conducted for the selection of artificial teeth for edentulous patients with the help of extraoral facial measurement.

Materials and methods

The intercanthal distance, interpupillary distance, interalar distance, intercommissural distance, and width of maxillary six anteriors from a total of 250 subjects were measured clinically. The measurements were made with the help of a digital caliper. Student's t-test was used to find the significance of parameters between male and female. Pearson correlation has been used to find the relation of the parameters.

Results

The total mean of 125 male subjects for intercanthal distance, interpupillary distance, interalar distance, intercommissural distance, and intercanine width was 31.58, 62.27, 34.77, 48.87, and 50.22 mm respectively. However, the total mean of 125 female subjects for intercanthal distance, interpupillary distance, interalar distance, intercommissural distance, intercanine width was 30.58, 61.48, 34.58, 48.20, and 49.34 mm respectively. The paired t-test showed highly significant results in relation to intercanthal distance and width of maxillary six anteriors. However, interalar distance was found to be nonsignificant and interpupillary and intercommissural distance was significant.

Conclusion

It can be concluded that although various methods for the selection of teeth are used, the applicability can vary due to the ethnic differences between populations. The multiplication factor for intercanthal distance, interpupillary distance, interalar distance, intercommissural distance was 1.6, 0.8, 1.4, and 1 in order to obtain the mesiodistal width of maxillary six anteriors respectively, in males and females. The values were greater for men than for women. No significant differences were found between sexes with respect to intercanthal distance.

Clinical significance

Although there are ethnic differences between populations, the proportions/relationships of anatomical landmarks to the teeth remain the same, which helps in the selection of artificial teeth for edentulous patients.

Effect of Relief at the Median Palatal Plate on Denture-supporting Ability

[Year:2017] [Month:October-December] [Volume:7] [Number:4] [Pages:7] [Pages No:117 - 123]

Abstract

Aim

A new maxillary palatal plate-form device that simultaneously measures clenching force and subsidence of the palatal mucosa at the onset of jaw clenching pain was developed to ascertain the effect of median palatal plate relief on denture-bearing ability.

Materials and methods

In 15 dentulous subjects, pseudo-palatal plates were affixed to the palatal mucosa; anterior splints were affixed as maxillary references for measuring subsidence upon transmission of the clenching force through a pressurizing splint affixed to the mandible. The relief at the median palatal plate was categorized as: No-relief, 0.23 mm relief, and 0.46 mm relief. Subjects clenched their jaws until they experienced pain. The clenching force and subsidence of the palatal mucosa were simultaneously measured and compared across relief categories, and their relationship to the extent of relief at the onset of pain was evaluated.

Results

At the onset of pain, both clenching force and subsidence of the palatal mucosa in the relief conditions were significantly greater than those in the no-relief condition (p < 0.05). In some patients, both clenching force and subsidence of the palatal mucosa decreased with increase in relief.

Conclusion

Relief at the median palatal plate effectively increases the bearing ability of the palatal part. However, the range and extent of relief might vary, depending on oral conditions.

Clinical significance

Using this approach, the relief area of maxillary full dentures suitable for individual patients was determined in an objective and convenient manner and the accuracy of denture treatments was improved. This could improve the quality of life of patients wearing dentures.

Interoperator Variability in Shade Selection using Two Shade Guides

[Year:2017] [Month:October-December] [Volume:7] [Number:4] [Pages:5] [Pages No:124 - 128]

Abstract

Statement of problem

Research shows that correct shade matching for porcelain restoration cannot be achieved accurately even after using visual shade guides because there is always a noted difference in the visual perception of operators.

Purpose

This study was conducted to compare the interoperator variability in shade selection by visual techniques using VITA Toothguide 3D-Master and Vitapan classical shade guide and then to calculate the amount of percentage in variability in shade selection.

Materials and methods

Three prosthodontists selected the shade of upper right central incisor of 100 patients (age 20—30 years) in a standardized environment. Two shade guides were used—Vitapan classical shade guide and the VITA Toothguide 3D-Master (Vita Zahnfabrik) for shade selection. Each examiner was tested to eliminate color blindness.

All teeth were polished before each shade selection, and the selection process was standardized for controlled lighting and procedures. The results were analyzed for repeatability using agreement analysis test, t-test (p = 0.05).

Results

According to the agreement analysis, there was about 14% of interperson variability seen in Vitapan classical shade guide and about 23% in VITA Toothguide 3D-Master.

Conclusion

Within the limitations of this study, the following result was drawn: VITA Toothguide 3D-Master showed higher interperson variability than Vitapan classical shade guide.
