“…[ 10 ] However, it has not been applied the method to determine the occlusal vertical dimension. For the determination of the occlusal vertical dimension, morphological evidence, such as cephalograms[ 11 - 13 ] and facial measurements,[ 14 - 17 ] has been used. Additionally, functional evidence such as the resting position of the mandible[ 1 18 19 ] and mandibular position at the time of the pronunciation has also been used.…”

A BSTRACT Background: Producing dentures for edentulous patients is important to improve quality of life of elderly. The determination of the occlusal vertical dimension on producing dentures is one of the key factors for using the dentures comfortably. The purpose of this study is to consider the usefulness of the determination of the occlusal vertical dimension of a facial measurement method applied on scanned facial image using a noncontact three-dimensional measurement device. Materials and Methods: Twenty-four dentulous individuals (mean age 26.6 ± 2.4 years old) were examined in this study. A noncontact three-dimensional measurement device was used for the scanning of the face both in the holding by hand and the fixing to the camera stands situations. The distances between subnasal and gnathion, pupil and oral slit, middle of glabella and subnasal, and right and left corners of the mouth were measured on the scanned face image and compared with the actual values. Results: The significant differences were not recognized on the four measurement items between the distance of actual values and obtained on scanned data (fixing conditions). The coefficients of variation of the distances between subnasal and gnathion, and pupil and oral slit on scanned data (fixing condition) were significantly lower than those at actual conditions ( P < 0.05). Conclusion: The results of this study suggested that a stable facial measurement can be successfully implemented by using a noncontact three-dimensional measurement device. This method yields outcomes which match the actual values.

“…The Willis device was developed to measure the distance from the lower border of the nasal septum to the lower border of the chin and from the outer canthus of the eye to the corner of the relaxed lip with the teeth in occlusion. While these measurements are theoretically equal, facial asymmetry calls their values into question [ 10 ].…”

Objectives: Accurate occlusal vertical dimension (OVD) establishment is an essential component of prosthodontic treatment. No accurate approach exists to determine the appropriate OVD for patients without posterior teeth. This study aimed to correlate the accuracy of the nose-to-chin distance with various facial measurements and thumb length in dentulous and edentulous Saudi patients. Materials and methods: The participants comprised 100 fully dentulous Saudi male dental students aged 20-30 years (group 1) and 20 completely edentulous patients aged 60-70 years (group 2). We evaluated the correlations between the OVD (nose-to-chin distance) and the distance from the pupil to the corner of the mouth, the vertical length at midline of the nose (from subnasion to glabella), the distance from the outer canthus of one eye to the inner canthus of the other, twice the distance between the inner canthi, and the distance from the thumb tip to the index fingertip. Statistical analysis: Spearman’s correlation and regression analysis were performed to analyze and assess the correlations between the clinically measured nose-to-chin distance and other parameters, with significance set at 0.05. Results: In edentulous patients, the results showed a significant, strong, positive correlation between the nose-to-chin distance and the distance between the pupil and the mouth corner. In dentate subjects, a significant, strong, positive association was found between the nose-to-chin distance and the distance from the outer canthus of one eye to the inner canthus of the other. The linear regression analysis revealed that the distance between the pupil and the mouth corner in edentulous patients significantly predicted the OVD. Conclusions: In both groups, the distance from the outer canthus of one eye to the inner canthus of the other and the distance from the pupil to the mouth corner were reliable and accurate for OVD measurements. These could be considered appropriate methods for OVD determination during full-mouth rehabilitation.

“…OVD is a more stable position and not influenced by gravity or head position and is therefore easier to record compared to https://doi.org/10.3126/mjmms.v3i5.60073 VDR [2]. Many techniques to determine the correct OVD have been proposed like the use of pre-extraction records, physiologic rest position, closing forces (Boos bimeter method), tactile sense, phonetics, esthetic appearance, open rest method, facial measurements, deglutition and the electromyographic method [3]. Finding a reliable method to determine the correct OVD has always been a challenge for the clinicians in the field of complete denture prosthodontics.…”

INTRODUCTION: Determination of the proper vertical dimension during prosthesis construction is of paramount importance in treating patients with missing teeth. This study was conducted to correlate the measurement of finger length with occlusal vertical dimension. MATERIALS AND METHODS: An analytical cross-sectional study was conducted in the Department of Prosthodontics, Tribhuvan University Teaching Hospital, Maharajgunj, Kathmandu, Nepal among 145 MBBS and BDS students. Length of four fingers and vertical occlusal dimension were measured by two anatomical methods with the use of vernier calipers. Data were analysed in SPSS version 20. Mean, standard deviation, frequency and percentage were calculated depending upon the nature of data. Pearson’s correlation was used to determine the relation between finger length with vertical occlusal dimension. RESULTS: Moderate positive correlation was found between occlusal vertical dimension (OVD) measuring tip of nose to gnathion and base of nose to menton with all four fingers (p<0.001 each). When compared for males and females, significant moderate correlation was found between OVD by both methods and anthropological measurements in all the four fingers in males (p<0.001 each) but only with index finger when OVD was measured from tip of nose to gnathion in females (p<0.001). CONCLUSIONS: The findings of this study concluded that all four fingers may be used for determination of OVD in males but only index finger may be used in females.
