The Treatment of a Maxillary Retrognathia Case with Rapid Maxillary Expansion (RME) and Face Mask Appliance, and 1- Year Follow Up After Treatment (Case Report)

In this case report, the treatment of an 10 years and 7 months old girl with skeletal Class III malocclusion charecterized with maxiller retrognathia using RME and face mask appliance and 1 year follow up. The screw turned 2 times a day until sutura opens and 1 times a day after opens and the use of the face mask was started after obtaining adequate expansion. The elastics with 1000 g force with 20°–30° to the occlusal plane were adjusted and the patient was told to use them for least 16–18 hours. Skeletal and dental Class III with anterior crossbite corrected and soft tissue anomalies were obtained from the successful changes afer treatment for 12 months. Although our patient is in pubertal period, and fixed orthodontic treatment is not applied after obtaining dental Class I occlusion in patient, the amount of relapse is very low and after 1-year follow-up, the occlusion has been seen to be stable

Sınıf I ve sınıf III ilişkili çocuklardaki sert ve yumuşak doku yüz morfolojisi farklılıkları: Sefalometrik inceleme

Aim: To assess the sagittal soft and hard soft tissue morphology of growing Class III patients in comparison with a Class I control subjects. Materials and Methods: Forty-one female children with Class III malocclusion and 30 Class I female children were included in the study. Eight linear and 6 angular measurements were made on lateral cephalograms to evaluate soft tissue and skeletal characteristics. Results: The subjects with Class III malocclusion showed a retrusive maxilla (A-y distance, 48.52±2.53) and upper lip (Ss-y distance, 64.14±3.26), a protrusive mandible (B-y distance, 56.15±5.49) a prominent chin (Pog’-y distance, 70.65±6.87), retroclined lower incisors (IMPA, 87.14±5.68), and increased vertical dimensions (SN-GoMe, 36.49±5.29) compared to control subjects. Conclusions: Our findings indicated that soft and hard tissue characteristics of Class III subjects are distinct from Class I subjects in the middle region and lower third of the face. Orthopedic traction of mid-face arguably started earlier as a first treatment protocol to obtain balanced facial profile in Class III subjects.Amaç: Bu çalışmanın amacı Sınıf III ilişkiye sahip çocukların sert ve yumuşak doku yüz morfolojisini Sınıf I ilişkiye sahip kontrol bireyleri ile karşılaştırmaktır. Gereç ve Yöntem: Bu çalışma Sınıf III maloklüzyonlu 41 ve Sınıf I oklüzyonlu 30 bayan çocuğu içermektedir. Bu bireylerin sert ve yumuşak doku karakteristiklerinin incelenmesi için sefalometrik filmler üzerinde 8 linear ve 6 açısal ölçüm yapılmıştır. Bulgular: Kontrol grubundaki bireylerle karşılaştırıldığında, Sınıf III maloklüzyonlu bireylerin retrüziv üst çene ve üst dudak, protruziv bir alt çene ve belirgin çene ucu, retrokline alt kesici dişler ile artmış dik yön boyutlara sahip oldukları görülmüştür. Sonuç: Bu çalışmanın bulguları, Sınıf III bireylerin orta ve alt yüz bölgesindeki sert ve yumuşak doku yüz karakterlerinin Sınıf I bireylerden farklı olduğunu göstermektedir. Sınıf III bireylerde dengeli bir yüz profile elde etmek için, maksiller protraksiyon ilk tedavi protokolü olarak daha erken başlatılmalıdır

Do children with Wilson's disease have distinct craniofacial morphology? A cephalometric study

WOS: 000322417900011PubMed ID: 23759337Objectives: Patients with Wilson's disease (WD) develop osseous changes such as osteoporosis, spontaneous fractures, areas of sclerosis and demineralization of maxillary and mandibular bones, and neurologic symptoms including swallowing dysfunctions, which may affect dento-facial growth. However, dento-maxillo-facial structures of these patients have never been investigated. The present study aimed to discover if subjects with WD have different dentofacial structures. Methods: Lateral cephalometric films of 13 children (5 males and 8 females) with WD and of 15 normal subjects (6 males and 9 females) were evaluated. Mean ages of the patients and controls were 12.62 +/- 3.09 years and 12.01 +/- 1.38 years, respectively. Lateral cephalometric cranial films of all subjects were taken in the same cephalostat in a habitual and unstrained body posture. Thirteen linear and 11 angular parameters were measured to describe the craniofacial characteristics of the subjects. Results: Statistical analysis showed that there is no statistically significant difference between parameters of normal children and children with WD, with the exception of palatal plane inclination. The inclination of palatal plane was higher in children with WD than in normal subjects. Conclusions: Children with WD and healthy children have approximately the same dento-maxillo-facial structures. However, increased palatal plane inclination may be a finding of WD
