يهدف هذا البحث لتحري أبعاد و توضع اللقم الفكية, و دراسة وجود تناظر بين اللقم الفكية اليمنى و اليسرى ,أو عدم التناظر الممكن ملاحظته للناتئ اللقمي و مدى علاقة ذلك بنموذج النمو الطبيعي لدى عينة من الأفراد الاناث البالغين بدون اعراض سريرية او شعاعية لاضطرابات المفصل الفكي الصدغي. مواد و طرق البحث: من خلال الاستعانة بالفحص الشعاعي و السريري متعدد المراحل, تم انتقاء 14 مريضة من العرق القوقازي و من ذوي نموذج النمو الطبيعي, ممن لم يخضعوا لمعالجة تقويمية سابقة , تراوحت أعمارهم بين17 و 29 سنة, و بدون اي اعراض لاضطرابات المفصل الفكي الصدغي. تم اجراء الدراسة على المقاطع السهمية و المحورية, ثم تم اجراء الدراسة السيفالومترية لتحديد نموذج النمو, و من ثم تم اجراء تحليل معامل ارتباط بيرسون و تحليل ستيودنت. النتائج: لم نجد ارتباطا ذو دلالة احصائية هامة ما بين قياسات المفصل الفكي الصدغي (الأيمن و الأيسر) في المسقطين السهمي و المحوري, مع نموذج النمو الوجهي الطبيعي. الخلاصة: لا يوجد ارتباط ما بين قياسات المفصل الفكي الصدغي (الأيمن و الأيسر), مع نموذج النمو الوجهي الطبيعي لدى أفراد من الاناث البالغين الغير خاضعين لعلاج تقويمي سابقا.
The aim of this research is to investigate the dimensional and positional symmetries between the right and left condyles ,and the possible asymmetries between the condylar processes that could be related to the type of growth pattern in adult subjects with no clinical nor radiographic symptoms of TMDs. Materials and methods: In result of a multistage clinical examination protocol, 14 Caucasian patients with normal growth pattern ,and with no prior orthodontics treatment were selected (14 females)from 17 to 29 years of age with no clinical signs and symptoms of TMDs. The images obtained from the axial and sagittal slices, Cephalometric growth pattern study was performed. Pearson's Correlation Coefficient and T-test were calculated. Results :no statistically significant relationship between the measurements of TMJ(left &right) and the normal growth pattern. Conclusions:There is no relationship between the morphology of TMJ and normal growth pattern in adult female orthodontically non-treated .

The research aim for testing the correlations between the morphology of the bone around the apexes of the central incisors and facial type.the sample consist of 59 patient.They were divided into three groups according to their facial Type.the result
is three groups ,19 short face type, 20 norm face type, and 20 long face type patients, aged 19 to 40 years.we have measured many measurement that determine the relationship between the apex of central upper incisor and its surroundings. The measurements were processed using analysis of variance Anova and Mann-Whitney U-tests and (Correlation coefficient )r .We find that at the upper central incisors, In short face type subjects the root apex of the upper central incisors was farther away from the lingual cortex than in the norm face type and long face type. In long face type subjects the root apex of the upper incisors was farther away from the palatal plane than in the norm face type and long face type.
Mandible articulates with the cranium via the TMJ. All the components of the TMJ,
including the TMJ disc, seem to be associated with altered characteristics of the
craniofacial complex and its growth. However, the exact role of the TMJ disc thickne
ss
during the process of the facial growth is not clear yet.
Aim: The aim of this study is to investigate the association between the TMJ disc
thickness and the facial growth determined according to Jarabak in adult male subjects
with no clinical or MRI symptoms of Temporomandibular Joint Disorders.
Facial structures, as well as their functions and correlations, have been extensively
studied to expand the knowledge of craniofacial growth and development and to optimize
growth predictions and proper indications of orthodontic and surgical treat
ments. The
cranial base forms the boundaries of the craniofacial complex . The nasomaxillary
complex is related to the anterior cranial base, whereas the mandible is related to its
posterior portion. Therefore, the shape of the cranial base is an important factor in
establishing the position of the maxilla and mandible. Aim: to investigate the relationship
of cranial base with jaws rotation in adult orthodontically non-treated subjects using Cone-
Beam Computed Tomography (CBCT) scan. Materials and methods: 27 Caucasian adult
patients with no prior orthodontics treatment were selected (16 males, 11 females)
.Cephalometric measurements determining type of jaw rotation were performed according
to Björk's analysis. Pearson's Correlation Coefficient was calculated to investigate the
relationship between the CBCT cranial base measurements and Cephalometric
measurements determining type of jaw rotation . Results: This study reveal vary
correlation between CBCT measurements of cranial base's dimensions and jaws rotation.
Conclusions: There is no relationship between the cranial base morphology and Jaws
rotation in adult orthodontically non-treated subjects.
Every osteotomy and every surgical correction of dentofacial deformity has
influences on the whole orofacial system including the TMJ. This study
aimed evaluate the effect on the TMJ after the orthognathic surgery
(bimaxillary osteotomy).Furthermo
re, a comparison was made between the
results obtained by bimaxillary osteotomy without condylar positioning and
the pre-operation centric position of the condyle.
It is generally agreed that growth in palatine results from bone formation at the
palatine sutures and lengthening of the alveolar processes, but the extent to which these
two sites contribute to the depth and length of the hard palate remains unso
lved. Hence,
professionals should use quantitative assessments of the hard palate, which allow more
accuracy in the diagnosis and assessment of this structure.
Aim investigating the relationship between the length and depth of the skeletal hard
palatine with facial growth type in adult subjects using CBCT scan.
