Orthodontic treatments can have an impact on the soft tissues and more particularly on the cutaneous profile. The aim of this work was to evaluate profile changes following orthodontic treatment. Material and methods: This study concerned 90 patients randomly selected in the orthodontic department of Monastir (Tunisia). Profile headfilms at the start and at the end of orthodontic treatment were compared using, as reference lines, the SN-7° plane and the orthogonal to SN-7° plane going through the S-point (POSN- 7°). The Student test was applied to evaluate the variations in the cephalometric measurements. The Pearson test was used to study the correlation between the horizontal tooth movements and facial profile changes. Results: We noted a significant decrease in the upper labral (Ls) (p=0.049) and lower labral (p=0.048) as well as a significant increase in the labio-mental angle (p=0.025) in patients treated with extractions of premolars. A positive correlation between the incisor movements and the reduction of the labial protrusion was observed. Conclusion: The results of this study have shown that the movements of the incisors consecutive to extractions can have tangible effects on the cutaneous profile. Further investigations should be carried out to highlight the relationship between tooth movement and soft tissue.

Subject. Facial aesthetics is an important motivating factor for many patients seeking orthodontic treatment. An aesthetically pleasing and balanced face is one of the objectives of orthodontic treatment. An understanding of the soft tissues and their normal ranges enables a treatment plan to be formulated to normalize the facial traits for a given individual. Aim. The aim of the present study is to further investigate the use of soft tissue analysis in the quantification of facial profile, and to investigate differences between different ethnic and gender groups. Methodology. A number of studies considered on various aspects of facial measurements in orthodontics. Results. Skeletal, dental and facial profile differences exist, when subjects from distinct ethnic groups are compared. Thus, each group should be evaluated differently, considering their racial characteristics, in order to produce better diagnosis and treatment planning. The necessity and acceptability of teeth extraction during orthodontic treatment and its effects on facial profile, has greatly concerned orthodontists for many years and has not lost its urgency till now. However, the definition of an attractive and pleasing face is subjective, with many factors involved (culture, personality, ethnic background, age). On the other hand, several medical specialties (orthognathic and plastic surgery, orthodontics, dental prosthetics) have the ability to change facial features. Hence, there is a need for clinicians working in the maxillofacial area to know the aesthetic standards of a face that guide the aesthetic soft tissue treatment goals in their patients. Conclusion: It will be useful to conduct investigations for further definitions and observations of correlated relationship between hard and soft tissues of maxillofacial system by taking into consideration: the patient's age at time of treatment, type of anomaly, differences in maxillofacial anatomical structures of various ethnic groups.

The purpose of the present study was to investigate the relationship between multidirectional lip­closing force and the three-dimensional morphology of perioral soft tissue in adults. Twenty-three Japanese adults with straight facial profiles participated in this study. The signals of directional lip­closing force (DLCF) were investigated in 8 directions. Three-dimensional morphology of perioral soft tissue was recorded using a 30 surface-imaging device. Correlations between lip-closing force and the three-dimensional morphology of the perioral soft tissue were analyzed statistically. Upper lip-closing force significantly correlated with the anteroposterior, vertical, transverse morphology of the upper lip, while lower lip-closing force did not correlate with the anteroposterior, vertical, or transverse morphology of the lower lip. In adults with straight facial profiles, associations were found between upper lip-closing force and upper lip morphology. There were no associations between lower lip-closing force and lower lip morphology.

Background: The general tendency of facial soft tissue response toward incisors retraction could be expected in various malocclusions. However, different initial malocclusion no doubt leads to differences in this response. Material and method: This retrospective study consisted of thirty-seven pre- and posttreatment lateral cephalographs belongs to adolescent female with mean age of 15.03 years. The twenty-four landmarks (skeletal, dental, soft tissue) were located and horizontal and vertical reference planes were used. Sixteen linear and six angular measurements were evaluated statistically. The pretreatment and posttreatment lateral cephalograms were superimposed on best fit cribriform plate of the ethmoid to analyze soft tissue facial profile changes after orthodontic treatment. Results: The three methods of error indicated that measurements were valid and reliable. The Labrale superius retraction exhibited the best predictability among upper lip components (Sn, Ss), whereas the lower lip showed better predictability and correlation than the upper lip. The upper and the lower lips revealed relatively similar mean retraction value (2.92 mm) and (2.6 mm) although the upper incisors retracted more (5.25 mm) than the lower incisors (2.86 mm). Conclusion: The upper incisors to Labrale superius ratio (1.99:1, UIP:Ls) exhibited the highest correlation (r=0.55**) among the other established ratios. The lower incisors to Labrale inferius ratio was (1.13:1, LIP: Is) with significant correlation (r=0.44**), whereas no significant correlation was observed with Labrale superius (r=0.27).

Ektopik kaninus seringkali dijumpai dalam praktek bidang ortodontik. Sebagian orang yang merasa terganggu dengan keadaan ini akan datang ke dokter gigi untuk mendapatkan perawatan. Perawatan ortodontik dilakukan untuk mengoreksi gigi yang ektopik dan memperbaiki fungsi estetik. Pada perawatan kasus ektopik kaninus ini, pencabutan gigi premolar kedua dilakukan karena tidak diperlukan perubahan profil. Teknik Begg merupakan teknik ortodontik yang menggunakan gaya ringan dengan kawat busur berpenampang bulat. Kawat busur akan bergerak bebas tanpa friksi dan menghasilkan gerak tipping mahkota gigi. Tujuan dari studi kasus ini adalah untuk memaparkan perawatan kaninus ektopik dalam tahapan teknik Begg. Pasien perempuan usia 19 tahun mengeluhkan gigi depan yang gingsul dan berjejal. Hasil pemeriksaan objektif menunjukkan ektopik pada gigi 13, 23 dan 33, overbite 5 mm, crowding anterior mandibula, dan crossbite anterior pada gigi 22 dan 33. Maloklusi kelas I skeletal dengan protrusif bimaksiler dan protrusif bidental, ektopik kaninus maksila bilateral, ektopik kaninus mandibula unilateral, deep bite, crowding anterior mandibula dan crossbite anterior. Dilakukan perawatan ortodontik cekat teknik Begg multiloop dengan pencabutan 15, 25, 36 dan 46. Sembilan bulan setelah perawatan, crossbite anterior, dan gigi 13, 23 dan 33 yang ektopik telah terkoreksi. Crowding anterior mandibula telah mengalami perbaikan dan perawatan masih berlanjut hingga saat ini. Perawatan teknik Begg multiloop dengan pencabutan gigi premolar kedua merupakan alternatif perawatan untuk koreksi ektopik kaninus, jika tidak diperlukan perubahan profil wajah pasien. ABSTRACT: Ectopic Canines Treatment Using Begg Technique with Second Premolar Extraction. Ectopic canines are often found in the field of orthodontic practice. People who are annoyed with this situation usually come to an orthodontist to seek for treatment. Orthodontic treatment has been performed to correct ectopic teeth and improve the function of aesthetics. In this case of ectopic canines, a second premolars tooth was extracted because profile changes are not required. Begg orthodontic technique is a technique that uses light forces by using round archwire. Archwire will move freely without friction and produce a tipping movement of dental crowns. A 19 year old female patient complained of ectopic and crowding anterior teeth. The objective examinations find ectopic of 13, 23 and 33, overbite: 5 mm, anterior mandibular crowding, and anterior crossbite of 22 and 33. Class I skeletal malocclusion, bimaxillar protrusive, bidental protrusive, bilateral ectopic canine maxilla and lateral ectopic canine mandibula, deep bite, anterior crowding and anterior crossbite. A fixed orthodontic treatment was performed by multiloop Begg technique with tooth extraction of 15, 25, 36, and 46. 9 months after treatment, anterior crossbite and ectopic 13, 23, 33 have been corrected by using multiloop Begg technique. Crowding in the lower arch has improved compared to initial condition and treatment still continues to this day. Multiloop Begg technique with second premolars extraction is an alternative treatment for ectopic canines correction if patient’s facial profile changes are not required.

Orthodontic therapy is best carried out in a normal skeletal and soft tissue environment. In patients requiring orthognathic surgery, it is suggested that there are advantages in correcting the skeletal and soft tissue elements as early as possible, and to orthodontically control the occlusion post-operatively. This results in a shorter overall treatment time due to more biologically favourable tooth movement, more predictable occlusal results and better management by the orthodontist. The clinical benefits of post-operative orthodontics are outlined.

ABSTRACT Objective To evaluate the esthetic perceptions of orthodontists and laypersons for facial profile changes after orthodontic treatment using Herbst or Forsus appliances. Materials and Methods Pre- and posttreatment facial profile contour images of 20 Class II patients treated with Herbst (group H; n = 10) and Forsus (group F; n = 10) appliances were analyzed by 30 orthodontists and 30 laypersons, who graded them from 1 (unattractive) to 10 (very attractive) using a visual analog scale. Two assessments were carried out with a 15 day-interval. In the first evaluation, 40 images were presented in a random sequence. In the second evaluation, initial and final facial profile images of each patient were randomly presented side by side. To compare groups in relation to treatment method, Mann-Whitney tests were used. To evaluate differences between time points, Wilcoxon tests were used. Results In the first evaluation, there was a significant difference between initial and final images only for group H, for both laypersons (P = .017) and orthodontists (P = .037). There was also a significant difference between laypersons and orthodontists in their ratings of posttreatment Herbst appliance profiles (P = .028). There was no significant difference between initial and final facial profile images for group F and no significant differences between or within evaluator groups in their ratings of initial or final Forsus appliance profiles. In the second evaluation, there was a significant difference between appliance groups only for laypersons, who considered cases treated with the Herbst appliance more attractive than those treated with the Forsus (P = .031). Laypersons also considered Herbst profiles more attractive than did orthodontists (P = .047). Conclusions Class II malocclusion treatment using the Herbst appliance may produce a more esthetically improved facial profile silhouette compared with Forsus appliances. The magnitude of perceived changes may not be considered clinically relevant.
