“…These findings together with the results of earlier published reports [17,33,47,50,51] suggest that methods based on the relationship between the anterior teeth and certain facial measurements may be used as preliminary guides in estimating the size of the maxillary central incisors in the absence of pre-extraction records in order to ensure acceptable aesthetics.…”

Introduction:The maxillary central incisor in particular holds the key in creating a highly esthetic frontal profile and therefore appropriate selection of the tooth is of utmost importance in the restoration of the anterior segment of teeth in completely or partially edentulous patients. Although a number of studies have suggested various reference guides towards estimation of the width of central incisor, there have been no suitable guides to ascertain the length of the incisor in the absence of pre-extraction records.Purpose of the study: The present study attempted to arrive at a correct proportion for determining as far as possible the correct length of the maxillary central incisor with the help of facial measurements in the absence of pre-extraction records in a small proportion of the subcontinent Indian population. Materials and methods:The distance from the bridge of the nose to the base was compared to the length (actual and calculated by regression) of the maxillary central incisor in 400 patients of both sexes between the age groups of 20-35 years.

“…However, there are no such evidences to suggest the validity of this relationship. Several authors [2][3][4][5] have made attempts to find a relationship between the maxillary frontal teeth and facial structures. The interpupillary distance has been suggested to relate the intercanine width and has been widely used for the selection of maxillary frontal teeth.…”

“…The placement of these lines is based on reference to certain definite facial landmarks, such as intercommissure, interalar, the labial frenum, bizygomatic width and interpupillary distance. [1][2][3][4][5] In the absence of pre-extraction records, 6 these facial and oral anatomical landmarks can be of utmost important for the clinician. The relative position of the canine while arranging the artificial denture teeth is critically important as it supports the corner of the mouth.…”

Purpose:The objective was to evaluate the correlation between the width of distal surface of canine (CWC), interpupillary distance (DMP) and intercommissural width (DCM) in a group of central Indian people. Materials and methods:A total of 540 central Indian subjects (277 males and 263 females) aged 19 to 30 years were selected. DMP and DCM were measured on subject's face using digital vernier caliper [Mitutoyo (UK) Ltd.] with precision of 0.01 mm. Irreversible hydrocolloid impression of the upper arch was taken, and a cast was poured with dental stone. The CWC measurements were done on these casts with the help of a dental floss fixed between the distoproximal contacts of upper canines using a dental tape. Spearman's correlation test was used to determine the correlation between the three variables studied. Results:The results revealed that the correlation between CWC-DMP was 0.015 and CWC-DCM was 0.031. The correlation showed negative values when compared between the sexes. Also, the proportions were calculated: DMP/CWC and DCM/CWC for the whole sample and for the sexes found no statistical significance (p > 0.05). Conclusion:The results of this study suggest that the examined interpupillary distance and intercommissural width cannot be considered reliable guidelines in the selection of artificial upper frontal teeth. However, they may be used as a useful additional factor combined with other methods for objective teeth selection in complete denture therapy.

“…However, this was not in accordance with other authors who either found it to be nonsignificant or not related. 13,23,25,26 This contradiction can be related to various methodologies used for measurement of either ICoW or intercanine distance. Width/Length (W/L) ratios of the anterior teeth are related to the anterior esthetics.…”

“…Studies have also used interalar width (IAW), intercommisural width (ICoW), interpupillary distance (IPD), and intercanthal distance (ICD) to predict maxillary anterior tooth width. 3,[12][13][14] Wehner et al 15 in 1967 suggested dropping parallel lines from the ala of the nose on the occlusal rims for the estimation of the width of maxillary anterior teeth between canine tips (ICTD). However, Picard 16 showed it to be related to the distance between the distal surfaces of canines.…”

Introduction: Several techniques and methods have been proposed to estimate the anterior teeth dimensions in edentulous patients. However, this procedure remains challenging especially when preextraction records are not available. Therefore, the purpose of this study is to evaluate some of the existing extraoral and intraoral methods for estimation of anterior tooth dimensions and to propose a novel method for estimation of central incisor width (CIW) and length (CIL) for Saudi population. Materials and methods:Extraoral and intraoral measurements were recorded for a total of 236 subjects. Descriptive statistical analysis and Pearson's correlation tests were performed. Association was evaluated between combined anterior teeth width (CATW) and interalar width (IAW), intercommisural width (ICoW) and interhamular notch distance (IHND) plus 10 mm. Evaluation of the linear relationship between central incisor length (CIL) with facial height (FH) and CIW with bizygomatic width (BZW) was also performed.Results: Significant correlation was found between the CATW and ICoW and IAW (p-values <0.0001); however, no correlation was found relative to IHND plus 10 mm (p-value = 0.456). Clinical significance: Based on the results of the study, ICoW and IAW measurements can be useful in estimating the initial reference value for CATW, while the proposed novel approach using specific palatal dimensions can be used for estimating the width and length of central incisors. These methods are crucial to obtain esthetic treatment results within the parameters of the given population.
