Age Related Changes

Age-related changes of jaws and soft tissue profile are important both for orthodontists and general dentists. Mouth profile is the area which is manipulated during dental treatment. These changes should be planned in accordance with other components of facial profile to achieve ultimate aim of structural balance, functional efficacy, and esthetic harmony. Through this paper, the authors wish to discuss age changes of the hard and soft tissues of human face which would help not only the orthodontists but also oral surgeons, prosthodontists, pedodontists, and general dentists.

Objective To supply quantitative information about the facial soft tissues of adult operated patients with cleft lip and palate (CLP). Design, Setting, and Patients The three-dimensional coordinates of soft tissue facial landmarks were obtained using an electromagnetic digitizer in 18 Caucasian patients with CLP (11 males and 7 females aged 19 to 27 years) and 162 healthy controls (73 females and 89 males aged 18 to 30 years). From the landmarks, 15 facial dimensions and two angles were calculated. Data were compared with those collected in healthy individuals by computing z-scores. Two summary anthropometric measurements for quantifying craniofacial variations were assessed in both the patients and reference subjects: the mean z-score (an index of overall facial size), and its SD, called the craniofacial variability index (an index of facial harmony). Results In treated patients with CLP, facial size was somewhat smaller than in normal individuals, but in all occasions the mean z-score fell inside the normal interval (mean ± 2 SD). Almost all patients had a craniofacial variability index larger than the normal interval, indicating a global disharmonious appearance. Overall, in patients pronasale, subnasale, and pogonion were more posterior, the nose was shorter and larger, the face was narrower, and the soft tissue profile and upper lip were flatter than in the reference population. Conclusions The facial soft tissue structures of adult operated patients with CLP differed from those of normal controls of the same age, sex, and ethnic group. In this patient group, surgical corrections of CLP failed to provide a completely harmonious appearance, even if the deviations from the reference were limited. Further analyses of larger groups of patients are needed.

Introduction: Facial profile improvement is goal of cotemporary orthodontics and a reason to seek orthodontic therapy. The soft tissue profile plays a important role on orthodontic diagnosis and treatment planning. The objective of this study is to investigate the relationship between positive clinical VTO and actual post-treatment soft tissue profile after phase l therapy of growth modification in Class II. Materials & Method: Pretreatment simulation of post-treatment and actual post-treatment profile photographs of 30 class ll div l patients treated with twin block appliance were compared. Three profile photographs of each subject; pretreatment, positive clinical VTO and post-treatment were taken and on each photograph four angles; Nasofacial (NF), Nasomental (NM), Mentocervical (MC) and Nasolabial (NL) were drawn and measured. Mean, standard deviation, success and coefficient of determination of each angle was measured and linear regressions analysis was applied to find out the correlation. Result: Nasolabial and nasomental angles showed greater success i.e. 81.4% and 68.1% respectively showing greater correlation, while nasofacial and mentocervical angles showed less success i.e. 48.1% and 48.3% respectively showing less correlation. Linear regression analysis revealed that positive clinical VTO significantly predicted post-treatment profile whereas coefficient of determination for nasomental and mentocervical angles was 76.5% and 60% representing a better goodness of fit while nasolabial and nasofacial angles was 53.6% and 51.6% demonstrating poor fit of regression lines. Conclusion: Even though there is improved facial profile obtained by protracting the mandible into class l relation in a chair side maneuver in class ll div l malocclusions, yet the orthodontist should be tentative when predicting the outcome of growth modification to get benefit of this therapy.

To establish the physical basis of subjective judgments of facial appearance, two novel computer-imaging programs differing in method of preparation and presentation of 5 features of the facial soft-tissue profile of 4 faces representing 4 different classifications of dental occlusion were compared. Images of facial soft tissue of 5 features were digitized and “animated” from 16 discrete distortions or morphed from the two extremes of each feature. 12 volunteer judges responded to both the “animated” and morphed presentations by pressing the computer mouse button when the image became acceptable and releasing the button when the image was no longer acceptable. They also pressed the mouse button when the most pleasing distortion appeared from either direction. Aggregating responses to counterbalanced trials and features across judges yielded high correlations between the programs for midpoint of acceptability. Although both programs provide reliable and valid measures of subjective acceptability of present and proposed changes in facial morphology, the new morphing program is more user-friendly than the “animated” method.

Malocclusion is very closely related to the disharmony of mesiodistaltooth-width with dental arches. It is important to know the mesiodistaltooth widths before establishing the diagnosis and planning oforthodontic treatment. The ultimate goal of orthodontic treatment isfacialesthetic, which is supported by a balanced soft tissue profile. The aim ofthis cross sectional study was to investigate the correlation betweenmesiodistal tooth widths with the convexity of soft tissue profile. Theresult of the study can be used as a reference and guidance inestablishing orthodontic diagnosis and treatment planning. The numberof sample was 50 (18 males and 32 females), aged 18-27 years old.Criteria for sample selection comprised absence of interproximalcaries/filling, no tooth deformity, aged over 17 years, never undergoorthodontic treatment, the presence of teeth from the right first molarthrough the left first molar, both upper and lower, Buginese orMakassarese people, and Class I Angle malocclusion. Tooth sizemeasurements were performed on study models by using slidingcaliper. The photo of each subject was taken cephalometrically. Theangular measurement was performed on cephalogram, using Subtelny'sanalysis. The soft tissue convexity degree was represented by N-SnPog.The data was processed using SPSS program and tested byindependent t-test and correlation. It can be concluded that the meanvalue of mesiodistal width on males was greater that those on females(p<0.05), the mean of facial convexity degree on males (159.05°) wassmaller than those on females (162.77°), which was different significantly (p<0.05), and there was a very weak correlation (r<0.25) oralmost no correlation between mesiodistal tooth-width and the degree ofsoft tissue facial profile, and it was not significant statistically (p>0.05).

Introduction: The soft tissue aspect in orthodontics treatment has gained attention in the last few years. The soft tissue profile is said to reflect the underlying skeletal profile, which causes a convex profile in patients with class II skeletal malocclusion. This research was aimed to determine the changes in the soft tissue facial profile of class II skeletal malocclusion patients with retrognathic mandible after twin block treatment. Methods: The type of research used in this study was retrospective descriptive research with paired t-test. The population was children aged 10-13 years old with class II skeletal malocclusion that were treated with twin block appliance in the Faculty of Dentistry Universitas Padjadjaran, Indonesia. The results of soft tissue changes before and after twin block treatment were compared. Results: There was an insignificant increase in soft tissue profile angle and Holdaway’s soft tissue angle after twin block treatment (p > 0.05). Whereas, Holdaway’s H-angle was decreasing and Merrifield’s Z-angle was increasing after twin block treatment, with statistically significant difference (p < 0.05). Conclusion: There was a decrease of H-angle, indicates a reduction in facial convexity and improvement of the facial profile after twin block treatment, but no difference in soft tissue profile angle and Holdaway’s soft tissue angle after twin block treatment. Keywords: Facial soft tissue profile, class II skeletal malocclusion, retrognathic mandible, twin block appliance

Age Related Changes

With aging, there are multiple internal and external factors that are associated with age-related changes in skin and soft tissue.  As Plastic Surgeons, we very commonly evaluate and treat elderly patients, often offering ‘anti-aging’ treatments.  An understanding of the science behind aging as well as common patterns of change seen in soft tissue may allow us to refine our treatments.  This review provides an overview of mechanisms underlying aging, as well common clinical scenarios with aging regarding anatomic sites commonly treated by Plastic Surgeons including the face, breast, and abdomen.  Separately, we discuss aging associated changes to specific tissue types, including skin, fat, muscle, and bone.  Knowledge of factors related to aging and concepts related to safe interventions to reverse or mitigate age-related changes and integral to our ability to care for the elderly population.   This review contains 9 figures, 3 tables and 69 references Key Words : Cellular senescence, mitochondrial theory, free radical theory, inflammation, protein damage hypothesis, glycation hypothesis, atrophy, lipotoxicity, rhytids, involution
