Correlation between the Individual and the Combined Width of the Six Maxillary Anterior Teeth

Abstract

The individual tooth width can be determined if the combined width of the maxillary anterior teeth is obtained by using a flexible millimeter ruler.

The significance of biometric parameters in determining anterior teeth width

“…Discussions on this topic are very present in the contemporary professional literature 2,7,8,[11][12][13][14][15][16][17][18][19][20][21][22] . Reviews of the recent scientific literature reveal studies that were carried out using different methodology and sample size, different face and natural teeth parameters 8, 10, 11-13, 15, 19, 20 , casts 5, 16-18, 21, 22 , or photographs 5,14,16,17,20 , as well as various types of gauges which makes the comparison of results very difficult.…”

“…Various face parameters such as bizygomatic 5, 10, 11 , interpupillar 5,8,10,11,16 , interalar 5, 8, 11, 14 , 16 , 19-22 and inner canthal distance 9,10,[12][13][14][15][16][17]22 , intercommissural distance 19,22 , width of the upper lip filtrum 9 and nose lengt [20][21][22] have all been proposed as objective guidelines for solving this problem. In the most recent scientific literature, there are different views about the true value of these methods [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] .…”

“…Authors of many recent studies suggest observing people's facial measurements in order to obtain objective guidelines for anterior teeth width selection, and measuring distances between certain reference points of the face 5,[8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] . These points are, as a rule, easily located, although their exact position is often defined differently by different authors.…”

Study of the morpho-dimensional relationship between the maxillary central incisors and the face

“…A great variation in the size of the tooth in relation to the face may affect the ability to obtain a good esthetic appearance. 7,8 It is important to know the mean widths and heights of the crowns of anterior teeth, because these provide the dimensions of the basic geometric shapes that will enable the dentist to detect features that are not esthetically pleasant, and reach a final result that allows qualitative disharmonies to be eliminated. 9 The shape of teeth can be classified as square, triangular and oval, and in the majority of cases there is some similarity between dental morphology and facial morphology, as well as a great deal of similarity in terms of shape and size among the teeth present in the same mouth.…”

“…9 The shape of teeth can be classified as square, triangular and oval, and in the majority of cases there is some similarity between dental morphology and facial morphology, as well as a great deal of similarity in terms of shape and size among the teeth present in the same mouth. 7 Moreover, the face can be classified as square-, triangular-or oval-shaped. 10,11 In 1914, Williams 12 suggested that there is a relationship between the shape of the face and the shape of the teeth.…”
