“…Silva et al, in a previous study, concluded that 3° of frontal incisal plane cant cannot be noticeable by the majority of laypeople . An angulation of 3.5° in the axial dental midline (vertical component) can be notice independently of the direction of the cant, specifically when midline was canted in the opposite direction of nose and chin deviations . There seems to be a relevant correlation between the vertical lines and the horizontal lines …”

“…Facial midline inclination seems to be relevant to determine the dental midline, but horizontal lines like the occlusal plane seem to be more related to the other horizontal lines like the interpupillary line and not really influenced by a nose and chin deviation. The outcomes of this study support that idea, at least from an esthetic standpoint.…”

“…8 This picture was edited and morphed creating a symmetrical facial model (SFM) using Adobe Photoshop CS3 Extended (for Mac/Windows VISTA). [7][8][9][10] On a previous research study 8 all the facial and dental parameters were tested separately. The thresholds of recognition were determined for this specific facial model and an asymmetrical facial model (AFM) was created, as shown in Figure 1A.…”

“…The dorsum, tip of the nose and chin were digitally shifted 3 mm to the left. [7][8][9] The aim was to create an asymmetric facial model that simulates what happens with a large number of our patients, which is, having an asymmetric face where asymmetries are subtle and present, but below the evident threshold of recognition. 8 Both the SFM ( Figure 1B) and AFM displayed a dental midline that was perpendicular to the interpupillary line and horizontally coincident with the philtrum.…”

Objective Facial asymmetries are common, especially deviated nose and chin. The clinician must consider these variables when establishing the smile, placement and angulation of the occlusal plane. The purpose of this article is to determine if nose and chin deviations affect the perception of laypeople towards different angulations of the occlusal plane cant. Materials and Method An asymmetric facial model was created from a symmetric facial model used in a previous study. Nose and chin were deviated 3 mm to the left and eight different pictures were created, each with different degrees of occlusal plane cant in both direction. Using a visual Likert scale delivered via Websurvey within the private practice setting, 120 randomly selected laypersons evaluated each image according to their own beauty preferences. Results In an asymmetric face, nose and chin deviated 3 mm to the left, a minor occlusal plane angulation of 2° can be perceptible regardless of the direction of the cant. Conclusions The occlusal plane should be as parallel to the interpupillary line as possible. If occlusal cant is present, less than 2° of angulation it is preferable, regardless of the direction of the nose and chin. Clinical Significance In the presence of an asymmetric face, the occlusal plane should be as parallel as possible to the interpupillary line. The direction of the deviation of the nose and the chin are irrelevant factors to determine the occlusal plane. An inclination of the occlusal plane can cause vertical discrepancy, which could subsequently create malocclusion. A complete dentofacial analysis can aim at assessing the angulation of the occlusal plane not only for esthetic outcomes, but for also allowing correct occlusal function.

Peg‐shaped maxillary lateral incisors cause many functional and esthetic major consequences in affected patients. Their esthetic and functional rehabilitations are often multidisciplinary, involving different clinical procedures like periodontal, orthodontic, or prosthodontic procedures. No exhaustive protocol has been established to improve their comprehensive management by general dentists or specialists. The aim of this article is to elaborate a simplified clinical protocol of complete management of peg‐shaped maxillary lateral incisors by a multidisciplinary team (general practitioners, orthodontists, and prosthodontists). A clinical case of two peg‐shaped maxillary lateral incisors completely rehabilitated with multidisciplinary approaches including orthodontic treatment and restoration by veneers and direct composite resin, according to the established protocol. Extraoral, intraoral, and smile clinical analysis are crucial to ensure optimal rehabilitation. Treatment results previsualization via wax‐up and/or mock‐up play a key role in the communication between practitioner and patient to help the latter make decision. These options also facilitate the achievement of a multidisciplinary approach by accurately estimating the number of dental movements and the type of restorations that are most suitable to the presenting clinical situation.

Layperson's perception of axial midline angulation in asymmetric faces

Abstract: The dental midline should be as vertically straight as possible. If a midline cant is present, however, it is more favorable to have a dental midline angulation which points in the same direction as nose and chin deviations, rather than in the opposite direction.
