Treatment Plans

To conduct a successful orthodontic treatment, we must understand a key concept and fundamental: aesthetics. Despite being a concept extremely subjective and influenced by culture, there are some features we can evaluate. An optimal smile is characterized by an upper lip that reach the gingival margins, with a curve or straight up between the philtrum and the corners, a line coincident with the upper incisal edge of lower lip minimal or absent negative spaces; commissural line and frontal occlusal plane parallel to the pupil, and some gum and dental components harmoniously integrated. Only when individualized and developed treatment plans for each patient, we can obtain acceptable aesthetic results.

The Relationship

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.

Lip Defect

The close resemblance of squamous papilloma with verrucous carcinoma and the chief etiological factor associated with its development, the human papillomavirus (HPV) raises a doubt about its close association with malignancy. The best way to treat HPV growths is surgical removal and assessment of lesion by histopathology. The defect needs reconstruction with full function and aesthetic outlook. Thirty-seven years old young man with history of tobacco chewing developed slow growing papilloma in upper lip in one year. It was excised fully and the defect was repaired by arterialized lip vermilion mucosal flap based on slightly tortuous labial vessel and so the flap could be elastically stretched even up to fifty percent of lip length and applied successfully. Same patient developed papilloma in lower lip as a separate primary after two years of nonrecurrence of previous operated upper lip papilloma. Lower lip lesion was excised similarly and repaired with same type of vermilion mucosal advancement flap from adjacent part of lower lip defect created. The post-operative period was uneventful and after three years of last operation there is no recurrence in either lip. Vermilion flap which is based on labial artery containing composite tissue comprising of mucosa and portion of orbicularis muscle mainly has been utilized to reconstruct the post excision papilloma lip defect with excellent functional and aesthetic results. There was no microstomia. It is single stage not involving donor site like tongue or cheek mucosa and is good upto half of lower lip defects.

Sialolithiasis, or salivary calculus, is a disease of the salivary glands, characterized by the formation of mineralized structures within the excretory salivary ducts or the glandular parenchyma. Approximately 80% occur in the submandibular gland, followed by the parotid and sublingual glands. Although rare, sialolithiasis can also occur in the minor salivary glands. Although the oral cavity and upper lip are the most common sites, they can develop in any region of the oral cavity that contains minor salivary glands. Treatment is based on surgical excision of the lesion, with a favorable prognosis. This study presents three cases of sialolithiasis of minor salivary glands of the upper and lower lip, addresses their clinical characteristics and correlation with microscopic findings, diagnosis and treatment plans. Etiology and factors that should be considered during diagnosis, appropriate treatment and improved prognosis are discussed in this study.

Summary Background/objectives Whether orthodontic treatment with functional appliances improves facial aesthetics is still under debate. This study aimed to determine whether functional orthodontic treatment improves the facial attractiveness of patients with Class II division 1 malocclusion. Materials/method Extraoral lateral photographs of 20 children with Class I (CLI, 11.7 ± 0.8 years), and before (T1) and after treatment (T2) photographs of patients with Class II division 1 (CLII T1 and CLII T2; mean age ± SD = 11.1 ± 0.6 years) treated with functional appliances, were transformed into black silhouettes. Three panels of examiners including 30 orthodontists (39.0 ± 10.1 years), 30 dentists (40.0 ± 9.7) and 30 laypersons (39.0 ± 9.2) evaluated the attractiveness of patients’ silhouettes using a 100-mm visual analogue scale, and the sagittal position of patients’ upper lip, lower lip, and chin using a 3-point Likert scale. Two-way ANOVA and a chi-square test were used to test differences among groups. Statistically significance was set as P  &lt;  0.05. Results The silhouettes of CLII T2 individuals were more attractive than those of the other groups (all Ps &lt; 0.001). The upper lip, lower lip, and the chin of these individuals were judged to be normally positioned in 69.5 per cent, 74.9 per cent, and 72.3 per cent of the assessments, respectively (all Ps &lt; 0.05). Limitations This study did not account for the psychological profile of the examiners, which may have affected the ratings. Conclusions/implications Orthodontic treatment with functional appliances is associated with a superior facial profile attractiveness. Functional treatment should be considered as a treatment option to improve the facial appearance of children with Class II division 1 malocclusion.

Abstract Introduction An attractive or pleasing smile enhances the acceptance of an individual in the society by improving interpersonal relationships. In this new era of social media, people are more concerned about their smile; hence, smile esthetics has become the primary objective of orthodontic treatment. It is seen that various smile parameters change with age and gender. Aim The aim of the study was to evaluate various smile parameters in nongrowing patients using photographic analysis. Materials and Methods The sample comprised photographs of 50 subjects (8 males, 42 females) taken in natural head position and then divided into two age groups: Group I (25 subjects, aged 18–20 years) and Group II (25 subjects, aged 23–29 years). The various parameters were analyzed using Adobe Photoshop software (version CS 6; Adobe System Inc., California, United States): upper lip and lower lip lengths during rest and smiling, smile index, buccal corridor, upper and lower lip thickness, interlabial gap, incisal display, widest visible maxillary display, and intercommissural width. Results The results showed that lower lip length at rest and smiling, interlabial gap, incisal display, inner commissure width, and widest visible maxillary display were increased, whereas upper lip length both at rest and smiling, upper and lower lip thickness, outer commissure width, smile index, and buccal corridor were decreased with age. Statistically significant sex-related differences were found in upper lip length at rest and lower lip length both at rest and smiling. Conclusion Orthodontic treatment must incorporate various esthetic elements of smile to achieve desirable results.

INTRODUCTION: A female patient aged 12 years and 2 months had molars and canines in Class II relationship, severe overjet (12 mm), deep overbite (100%), excessive retroclination and extrusion of the lower incisors, upper incisor proclination, with mild midline diastema. Both dental arches appeared constricted and a lower arch discrepancy of less than -6.5 mm. Facially, she had a significant upper incisors display at rest, interposition and eversion of the lower lip, acute nasolabial angle and convex profile. OBJECTIVE: To report a clinical case consisting of Angle Class I malocclusion with deep overbite and overjet in addition to severe crowding treated with a conservative approach. METHODS: Treatment consisted of slight retraction of the upper incisors and intrusion and protrusion of the lower incisors until all crowding was eliminated. RESULTS: Adequate overbite and overjet were achieved while maintaining the Angle Class I canine and molar relationships and coincident midlines. The facial features were improved, with the emergence of a slightly convex profile and lip competence, achieved through a slight retraction of the upper lip and protrusion of the lower lip, while improving the nasolabial and mentolabial sulcus. CONCLUSIONS: This conservative approach with no extractions proved effective and resulted in a significant improvement of the occlusal relationship as well as in the patient's dental and facial aesthetics.

Inferior-superior displacements of the upper lip, lower lip, and jaw were transduced with a strain-gauge system in 4 normal-speaking adults. Movements of the upper and lower lips were compared across conditions in which the jaw was free to move and when bite blocks were used to fix the jaw at four different vertical positions. As jaw-open position was increased with the bite blocks, it was found that: (a) Positions of both lips changed for bilabial closure, but the closing movements did not usually maintain consistent proportions between lips across different bite-block sizes; (b) although the lips maintained fairly consistent maximum interlabial opening across many conditions, this opening was reduced in the small bite-block conditions; and (c) in a few cases there was an increase in the duration of lip-closing movements, but these were small and inconsistent. The findings are discussed relative to possible organizational systems that would produce the observed interactions among speech articulators.
