يعتبر التثبيت بين الفكينن IMF حجر الزاوية خلال الجراحات المرتبطة بإعادة البناء الفكين الوجهي التقويمي وجراحة الرضوض الوجهية , تعتمد المعالجة الناجحة لكسور الفك السفلي على الرد التشريحي الصحيح وترميم الإطباق الطبيعي والتثبيت ( التوقيف) لفترة محددة من الوقت. لذلك تحاول هذه الدراسة تقييم أذية الجذر السني في سياق التثبيت بين الفكينن باستخدام براغيpre-drilled bone screws في معالجة كسور الفك السفلي غير المتبدلة أو ذات التبدل البسيط . وذلك من خلال مراقبة الاختلاطات سريرياً وشعاعياً لتقييم أذية وفقد حيوية جذر السن المجاور. ومن ثم إخضاع البيانات للدراسة الإحصائيَّة التحليليَّة باستخدام كاي مربع عند قيمة0.05 p˂. وقد توصلت هذه الدراسة إلى أن تقنية التثبيت بين الفكينن IMFباستخدام براغي pre-drilled bone screws طريقة آمنة للتثبيت بين الفكينن, لكنها لا تخلوا من الاختلاطات أو العواقب الكامنة التي يجب على الجراح أن يكون واعياً لها للحصول على معالجة آمنة وفعالة
IMF serves as a cornerstone during surgeries related to reconstruction orthognathic and facial trauma surgery. Successful treatment of mandibular fractures depends on reduction and restoration of normal occlusion and immobilization. So this study attempts to evaluate dental root damage through intermaxillary fixation with pre-drilled bone screws in the management of non-displacement or mini-displacement mandibular fractures. Complications were observed clinically and radiologically to evaluate the damage and loss vital to the adjacent tooth root. Data were subjected to statistical analysis using Chi Square Test. P-Value<0.05 was considered significant .This study found out that the intermaxillary fixation screws proved to be a safe technique to the intermaxillary fixation; however, it is not without complications or potential consequences which the surgeon must be aware of in order to provide safe and effective treatment.

The purpose of this study was to evaluate the reliability of a single malleable noncommpression
titanium miniplate in fixation and stability of fractures of the mandibular
angle using two approaches(.transbuccal and intra-oral approach, or intra-or
ally alone) .
The research sample included 20 patients from patients who attended AL Assad
University Hospital with Unilateral or bilateralun-comminuted mandibular angle fractures
in the period between September 2011 and October 2013.
The research sample was divided into two groups depending on the two approaches
that have been used . Adequacy of the reduction and stability of fixation were evaluated
through Radiographic examinations immediately after surgery. Postoperative assessment
was based on clinical examination after 1 month, 6 monthes and a year to evaluate:
Occlusion, Masticatory efficiency, Maximum mouth opening range, and Other
complications(infection –mini-plate exposure).
The results of the present study showed that there were statistical difference between
the two approaches(transbuccal and intra-oral approach, or intra-orally alone) regarding
Occlusion, Masticatory efficiency and Other complications after 1 and 6 months while
there was no statistical difference between the approaches after 1 year .
we Concluded that using the combined transbuccal/oral approach was the best
regarding(infection and mini-plate exposure) and compared with intra-oral approach .
Closed reduction and percutaneous pin fixation is considered
standard management for displaced supracondylar fractures of the
humerus in children. However, controversy exists regarding whether
to use pins from the lateral side or medial and latera
l side of the
elbow for fixation .
We performed this research to know the results of two ways of
treatment and to compare : 1- the risk of iatrogenic ulnar nerve
injury caused by pin fixation . 2- quality of fracture reduction in
terms of radiographic outcomes . 3- compare function of the elbow
and other surgical complications caused by pin fixation between two
ways.
Fractures of the mandibular condyles are frequent in facial traumas and their treatment represents a highly controversial issue in maxillofacial traumatology, functional and surgical treatments being the two principal management modalities for such f
ractures.
The aim of this study is to evaluate the results of functional treatment of mandibular condylar fractures in patients which received this type of treatment.
Eighty-six patients between 6 and 66 years old who were previously treated fuctionally for a fracture of the mandible condyle were recalled for follow up examination with a mean postoperative observation time of 10.4 years. Mandibular function was assessed using the mandibular function impairment questionnaire and patient's complaints were assessed during physical examination. The results showed a significant increase of dysfunction index values with increasing age at the time of trauma. Radiologic abnormalities such as reduced ramus height, deviation of the mandibular midline, and irregular shape of the condyle were observed and seen frequently, but they were not correlated with the severity of dysfunction. Predictors of mandibular function impairment after closed treatment of fractures of the mandibular condyle were: great deviation, reduced mouth opening, women gender, and increased age. The results of this study support the opinion that functional treatment is sufficient in pediatric patients, whereas in older age groups the results of conservative treatment are less sufficient
The purpose of the present study was to radiologically assess the
hard tissue changes around the immediately loaded implants single
tooth bioactivated with plasma rich in growth factors ,placed in the
mandibular posterior region . Twenty dental im
plants placed in 13
patients had at least single edentulous space in the posterior
region of the mandible using single stage procedure after
bioactivation the implants surfaces with plasma rich in growth
factors.
The aim of the study was to evaluate The relation between morphology of lips and incisors and mandibular rotation in adult class Ι individuals and to explore the gender dimorphism for these measurments. Material and methods True lateral cephalometri
c radiograph of the sample that comprises 32 females and 30 males aged 18-25 years and they possess class I skeletally and dentally. The data were analyzed using independent sample t test and Pearson correlation analysis. Results: In males interlabial angle negatively correlated with U1-NS and positively with U1-L1 Nasolabial angle and mentolabial angle positively correlated with (NS-GoMe, FH-GoMe, B, Bijork angles) Zangle and ULT/ULH negatively correlated with (NS-GoMe, FH-GoMe, B, Bijork angles) in Females lower lip inclination positively correlated with (NS-GoMe, FH-GoMe, B, Bijork angles).
