The purpose of this comparative study was to evaluate the correlation between two radiographic methods used to evaluate skeletal maturation, hand-wrist analysis method and cervical vertebrae analysis method. Within the limits of this study, the cervical vertebrae maturation method might mislead the clinician when treating adolescent skeletal Class II patients at the pubertal growth spurt since it is not correlated with hand wrist skeletal maturation method.

Research summary
هدفت هذه الدراسة إلى تقييم الارتباط بين طريقتين شعاعيتين لتحديد مراحل النضج الهيكلي عند مرضى سوء الإطباق الهيكلي من الصنف الثاني خلال البلوغ. استخدمت الدراسة طريقتين: تحليل عظام اليد والرسغ باستخدام طريقة Fishman، وتحليل الفقرات الرقبية باستخدام طريقة Hassel and Farman. شملت العينة 37 مريضًا سوريًا (18 ذكورًا و19 إناثًا) بمتوسط عمر 13.12 سنة. تم حساب معامل الارتباط Spearman لتحديد العلاقة بين الطريقتين. أظهرت النتائج عدم وجود ارتباط دال إحصائيًا بين الطريقتين، مما يشير إلى أن طريقة الفقرات الرقبية قد تكون مضللة عند معالجة مرضى الصنف الثاني الهيكلي في ذروة قفزة النمو البلوغية.
Critical review
دراسة نقدية: على الرغم من أهمية الدراسة في تسليط الضوء على عدم الارتباط بين طريقتين شائعتين لتقييم النضج الهيكلي، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، حجم العينة صغير نسبيًا، مما قد يؤثر على قوة النتائج. ثانيًا، كان من الممكن تضمين مجموعة مقارنة من مرضى بدون سوء إطباق هيكلي لتحسين فهم الفروقات. ثالثًا، لم يتم التطرق إلى تأثير العوامل البيئية أو الوراثية التي قد تؤثر على نتائج النضج الهيكلي. وأخيرًا، كان من المفيد تقديم توصيات واضحة للممارسين حول كيفية التعامل مع هذه النتائج في الممارسة السريرية.
Questions related to the research

  3. ما هي النتائج الرئيسية التي توصلت إليها الدراسة؟

    النتائج أظهرت عدم وجود ارتباط دال إحصائيًا بين مراحل مؤشر النضج الهيكلي SMI ومراحل مؤشر نضج الفقرات الرقبية CVMI.

  4. ما هي التوصية الرئيسية للممارسين بناءً على نتائج الدراسة؟

    التوصية الرئيسية هي أن طريقة تقييم نضج الفقرات الرقبية قد تكون مضللة عند معالجة مرضى الصنف الثاني الهيكلي في ذروة قفزة النمو البلوغية، ويجب الحذر عند استخدامها.

Class II malocclusion is a common clinical problem among white Caucasian population and its transverse component is a critical aspect of a functional and stable occlusion. The size and shape of the arches have considerable implications in orthodontic diagnosis and treatment planning, affecting the space available, dental esthetics, and stability of the dentition. Hence , it is important to study the alveolar arch width in this group of patients using the wide possibilities of cone beam computed tomography of evaluating real anatomy , true-to-scale images without distortions or superimpositions, and the selection of the desired sections.Objective:To evaluate the width of maxillary and mandibular alveolar arches in skelatal Class II adults compared to skeletal class I using cone beam computed tomography. Materials and methods: thirty-two subjects with skeletal Class II relationship and 10 subjects with skeletal Class I who were ordinary undergoing CBCT scan for non-orthodontics nor for otorihnolaryngology purpose were selected to measure the maxillary and mandibular alveolar width of first premolar and first molars.Independent samples’ t-test was calculated. Results:No statistically significant differences were found of alveolar widths between skeletal Class II and Class I subjects in both maxillary and mandibular widths of molar and premolar regions. Gender had no statistically significant effect in the results of the study. Conclusion :There is no differences in alveolar width between adults with skeletal Class II and Class I relationships, so the transverse discrepancy in skeletal Class II when exsists , it is more probably not originated from the alveolar base.
The asymmetric face is common so that increased interest in it .there are different ways to assess the asymmetry. Computed tomography is an accurate way that enable the examiner for reading the face at three planes ,and present three-dimensional in formation on the cranial mandibular Complex whereas (3D) analysis is essential for making a precise diagnosis of craniofacial morphology. Aim : This research aims to study the asymmetric at the facial patterns malocclusion (class I. Class II) using CT . the research sample consists of 48 CT image (male 23 and female 15)their ages ranged between 18 and 35 years old and did not receive any orthodontic treatment before, and devided into two groups according to the malocclusion ptterns(17 class II, 31 class I ) . Analysis was performed T. student test then calculated for all the data obtained . This study showed that a significant difference between the class I and class II malocclusion in each of the right and left.
This study aims to determine the skeletal problems in sagittal plane in patients with congenital hypodontia. In this study, 96 cephalograms were taken of Syrian coastal father and mother. The sample was divided according to gender and to location of the missing teeth. The angles SNA, SNB and ANB were studied.
Since early Orthodontics, one of the main concerns is to correct Skeletal Class II. For this Purpose they designed different functional appliances, and performed many cephalometric studies to evaluate treatment results for these appliances on dent ofacial complex. Our clinical experience, show the ability of treatment of preadolescents by advancement the mandible in skeletal class II correction with Sliding Plates. and for this purpose, lateral cephalometric study was performed to evaluate treatment results at dentofacial complex. 19 preadolescents ages 11-14 years with skeletal class II and mandibular retrognathism Sliding Plates consist of two separated removable parts, the upper one has midpalatal expansion and vertical wire, the lower is provided with anterior bite plane. The plates were used for 6-12 months. Lateral cephalograms were taken before treatment and immediately after treatment. The results after treatment were compared with the pretreatment measurements before treatment. After treatment, advancement of the mandible and the parts of TMJ has been observed. Thus, the use of sliding plates are useful to correct skeletal class II with mandibular retrognathism, especially in cases associated with narrow upper dental arch for children their ages do not permit the use of pre-functional preparation, and additionally, in cases that require functional rehabilitations.
