A new technique to determine vertical dimension of occlusion from anthropometric measurements of fingers

Abstract

Since the variations between VDO and finger lengths are within the range of 2-4 mm, VDO prediction through this method is reliable, and reproducible. Also the method is simple, economic, and non-invasive; hence, it could be recommended for everyday practice.

Correlation between the occlusal vertical dimension and the pupil rima oris distance among Sundanese population

“…Therefore, in order to evaluate the OVD, a pluralistic method should be adopted at all the stages of rehabilitation in order to maximize the benefits and minimize damage to the stomatognathic system. 18 The results obtained in this research support almost all the hypothesis, hence the length of pupil-rima oris can be suggested to be used as one of the guide in the determination of OVD. However, other method of determination of OVD should be used together in order to obtain a more accurate measurement.…”

“…Also, it does not require a great amount of time and experience to master which is another advantage over previous methods. 18 Besides the pupil-rima oris, there are many other methods in previous studies which is using the anthropometric landmarks to compare with the OVD. Anthropometric measurements were used in order to determine proportions of body parts since antiquity, when sculptors and mathematicians followed the golden proportions, later specified as a ratio of 1.618:1.…”

“…The hypothesis of this research was that there should be a significant relationship between the occlusal vertical dimension and the length of pupil-rima oris. 18 In a book ''Anatomical Studies'' by Leonardo Da Vinci contributed several observations and drawings on facial proportions. He found chin-nose distance equal to the superior surface of right ear to inferior surface of right ear, hair line to right eyebrow line and two times of outer canthus of right eye to inner canthus of right eye.…”

“…Moreover, the OVD estimated using this method is within the range of 2-4 mm which is significantly less if compared to other methods where a range of 0-14 mm is given. 18 The limitation of this study was that it was restricted to the subjects with Class I malocclusion and other skeletal or dental malocclusions were not considered. Also, the subjects were not categorized based on facial forms.…”

“…Further, the measurements is difficult to record when patient has a round facial profile with excessive soft tissue bulk under the chin. 18 To authenticate these findings, further studies should be carried out comprises of a board clinical research program that would include the similar analysis for dentulous population in other ethnic groups and then appropriate regression equations may be constructed which can be accepted universally. However, the operator should aware that OVD is the result of a mucoskeletal balance.…”
