Functional Aesthetic Occlusal Plane (FAOP)

Abstract

Introduction: A reasonable exposure of incisors and gingival tissues is generally considered more attractive than excess or lack of exposure. A reasonable gingival exposure is considered to be around 0 to 2 mm when smiling and 2-4 mm exposure of the maxillary incisor edge when the lips are at rest. Objective: The aim of this paper is to present the Functional Aesthetic Occlusal Plane (FAOP), which aims to help in the diagnosis of the relationships established among molars, incisors and the upper lip. Conclusion: FAOP can complement an existing and established orthodontic treatment plan, facilitating the visualization of functional and aesthetic demands by giving a greater focus on the position of incisors in the relationship established among the incisors, molars and the upper lip stomion.

“…Moreover, younger individuals have greater maxillary incisor exposure, while older people have greater mandibular incisor exposure. This highlights the aesthetic needs of patients according to age [4]. Thus, when treatment goals are reached in teenagers, the aesthetics and harmony of the smile are generally very satisfying.…”

“…However, aesthetic and orthodontic treatment must have an impact on the patient's well-being and quality of life [3]. According to Câmara et al incisors exposure during speech, at smiling and when the lips are at rest is an important factor in facial aesthetics, as it influences perception of the human face [4]. Moreover, younger individuals have greater maxillary incisor exposure, while older people have greater mandibular incisor exposure.…”

Treatment of bimaxillary protrusion using intra- and extra-alveolar miniscrews associated to self-ligating brackets system

“…The lower incisors required extrusion of 2.5 mm to touch the FAOP plane (FAOP=+2.5 mm/-2.5 mm). The FAOP evaluates the positioning relationship between molars, incisors and upper lip stoma 32 . The normal measure is 2.0 to 4.0 mm with the upper incisor.…”

“…It should be remembered that the working archwire used for retraction is 0.019 x 0.025-in stainless steel, and that there is a gap of nearly 12° between the arch and bracket slot. 32 If greater torque control was necessary, without the need to reduce the inclination, the prescription of choice would be high torque (central incisors +22°, lateral incisors +13° and canines +11°). In the lower arch, the torques in the incisors are more reduced (incisors -3° and canines +7°); the prescription of +7° in the canines prevents exaggerated lingual inclination of these teeth during retraction, helping in the transverse control.…”

Occlusal plane canting: a treatment alternative using skeletal anchorage

“…First, a photograph of a spontaneous smile must be captured to show the maximum elevation of the upper lip. 16 , 18 , 21 , 25 , 26 The photograph of the smile during occlusion is a part of the regular orthodontic documentation and may be used to identify any deviation in the upper arch. 17 , 27 , 28 Furthermore, another photograph may be captured, with a spontaneous smile and the mouth slightly opened, to evaluate the lower arch and the parallelism of the curvature of the upper arch with the lower lip.…”
