Extraction of #44 was done to alleviate crowding in the mandibular anterior region and #15 was extracted to protract #16 to achieve a Class II molar relationship. A pre-functional Class II molar and canine relationship with co-incident midlines was achieved. The functional phase consisted of a fixed functional appliance (Forsus FRD) for mandibular advancement to correct the severe skeletal Class II. Class I molar and canine relationships were achieved with reduction of facial convexity and overjet. Result remained stable 24 months after treatment. The improvement can be quantified by the reduction in scores of orthodontic indices measured pre and post treatment. \u0000Conclusions:                        Management of Class II subdivision malocclusion requires careful planning.

In the early 1990s Fred Bookstein created a classification system with landmarks type 1., type 2., type 3. based on anatomical landmark homology. However, thirty years later, a uniform referece index of landmarks that can be used for assessing facial asymmetry still does not exist. The criteria for selecting landmark points are not fully defined, which makes classification of homology and and landmarks prone to arbitrary interpretations. A systematic review of literature indicates that authors of studies do not provide explanation for choosing exact points. Most of them also do not provide a clear definition of landmarks and landmarks classification according to homology. \u0000Objective \u0000The objective of this systematic review was to assess, in an evidence based manner, which landmarks inside the Bookstein groups of on facial hard tissues can be reccomended for facial asymmetry assessment using geometric mophometrics. \u0000Search methods \u0000An electronic search of 9 databases up to March 2020 by two reviewers was conducted to identify relevant articles. \u0000Selection criteria \u0000Prospective randomized, non-randomized controlled trials and cross sectional studies reporting on facial asymmetry using three-dimensional images and geometric morphometric methods. The reasons for assessing facial asymmetry were not considered. \u0000Data collection and analysis \u0000The 23 selected studies were categorized according to the number and specification of the research subjects, types of three-dimensional images, number of landmarks, and the craniofacial region of interest. All landmarks were extracted with the following data: name, abbreviation, and the author’s definition of the location. \u0000Results \u0000The craniofacial region is divided into neurobasic cranial part, ethmomaxillar part and the mandible. Assessment of neurobasic cranial asymmetry was conducted in 6 studies and 45 different landmarks were recorded, of which 11 were medial and 34 bilateral. Bregma and Lambda occur most frequently and according to homology both belong to type 1 landmarks. \u0000Assessment of ethmomaxillary asymmetry was conducted in 21 studies and 68 different landmarks were recorded, of which 16 were medial and 52 bilateral. Nasion and Jugale occur most frequently and according to homology Nasion belongs to type 1 landmarks and Jugale to type 2 landmarks. \u0000 Conclusion \u0000The selection and definition of craniofacial hard tissue landmarks is one of the most important tasks in the design of morphometric studies, and thus for the purpose of assessing facial asymmetry. The review provides an extensive cross-section of possible landmarks with the definition of the location as well as the possible location variation. The list of these landmarks should be observed through the classification of landmarks according to their homology, as well as possible variations of the classification.","PeriodicalId":22042,"journal":{"name":"South European Journal of Orthodontics and Dentofacial Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77673960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim of the study: To investigate the effectiveness of cotton roll-biting on pain caused by the debonding procedure. Materials and methods: 102 patients (61 females, 41 males) who were at the debonding stage in orthodontic treatment were included in the research. The study was planned using a split-mouth design: one side of the jaw was the study, and the other side was the control. The anxiety level of participants was measured before debonding. On the study side, debonding was performed while patients were biting a cotton roll. On the control side, debonding was implemented as a routine debonding procedure. Study and control sides were assigned differently in each successive patient. The debonding pain of each tooth was recorded using the Visual Analog Scale prepared separately for each tooth. Shapiro–Wilk and Mann–Whitney U tests were used for statistical analysis. For both gender groups, patients were sequenced according to the average amount of pain per tooth. Subsequently, statistical analysis was repeated by using 50% of patients suffering more pain. Results: In the lower second premolar tooth, a statistically significant difference was detected. Pain scores were statistically higher in the study side for this tooth. No statistically significant differences were found for all other teeth. Conclusions: Cotton roll-biting has no alleviating effect on debonding pain.

The result produced by the lingual orthodontic appliance is parallel to those produced by the labial orthodontic appliance. However, there is an articulation problem due to the position of the lingual brackets as there is a modification of the lingual surface of the teeth. Speech problems with each appliance are studied individually and extensively, but the comparison of both appliances regarding speech is very scanty. Aim: The aim of this study is to evaluate the effect of fixed labial and lingual orthodontic appliance on speech sound production at a different time interval. Materials and methods: A total number of 30 patients were included in this study, 15 patients were bonded with the fixed labial appliance (Group 1) and 15 patients were bonded with the fixed self-ligating lingual appliance (Group 2). Based on four types of errors (E1, E2, E3, E4), a total of nine groups of sounds (S1, S2, S3, S4, S5, S6, S7, S8, S9) were evaluated for each audiovisual sample at four different time intervals (T1, T2, T3, T4) by two different speech therapist individually in each group. Results: A high degree of agreement was found between the two observers in both groups regarding the type of sound effected and the type of error during sound production. The total number of patients with effected speech is more in the lingual group compared to the labial group on the same day of bonding until six months in treatment. Conclusion: The results of the present study demonstrated the following, the total number of patients with lingual appliance had more errors in speech compared to the labial appliance at the beginning of the treatment. Patients with lingual appliance required more time for adaptation concerning speech. A similar group of sounds was effected in both types of an appliance with a similar type of error. Patients with labial appliance showed more comfort and easier adaptation with the appliance. The anatomical location of the appliance plays an important role in speech alteration and adaptation. These findings should be considered before selecting an appliance for a particular patient.

Maxillary distalization was achieved by a novel compliance-free appliance referred to as MaXimo, which was built by a rearrangement of the Leaf Expander® screw having palatal miniscrews as the anchorage core. Case Presentation: Pre-treatment, post-treatment and 1-year follow-up records are shown. No side effects, breakage of the appliance or loss of miniscrews was encountered. The active distalization phase lasted 14 months, while the whole treatment, including the use of multibrackets appliance, lasted 25 months. A significant spontaneous distal drifting of the premolars and canines was seen. The treatment outcomes proved to be stable at the follow-up with acceptable aesthetic and functional results. Conclusion: The MaXimo appliance proved to be efficient and of easy management, and its use may be recommended when distalization of the maxillary dentition is required. Being mostly assembled by the manufactured, the MaXimo appliance is also cheap and of easy construction.
