تم إجراء هذا البحث لمقارنة ثبات الجهاز السفليعند مرضى الدرد الكامل المعالجين بالأجهزة الكاملة التقليدية و الأجهزة الكاملة المصنعة بطريقة المواد السليكونية.
this study was conducted to compare the stability of the lower denture in edentulous treated with traditional complete dentures and dentures manufactured by silicon materials.

Research summary
تهدف هذه الدراسة إلى تقييم ثبات الأجهزة الكاملة السفلية لدى مرضى الذرد الكامل الذين يعانون من امتصاص السنخ السفلي. تم مقارنة طريقتين مختلفتين لصنع هذه الأجهزة: الطريقة التقليدية وطريقة المواد السيليكونية. شملت الدراسة 12 مريضًا (5 ذكور و7 إناث) تتراوح أعمارهم بين 55 و71 عامًا. تم قياس ثبات الأجهزة باستخدام مقياس القوة الرقمي، حيث أظهرت النتائج أن الأجهزة المصنوعة بالطريقة التقليدية كانت أكثر ثباتًا بمقدار 7.3 مرات مقارنة بالأجهزة المصنوعة بالمواد السيليكونية. توصي الدراسة باستخدام طريقة المواد السيليكونية لتحسين ثبات الأجهزة الكاملة السفلية وزيادة فعالية المضغ لدى المرضى.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة في مجال طب الأسنان التعويضي، حيث تقدم مقارنة شاملة بين طريقتين مختلفتين لصنع الأجهزة الكاملة السفلية. ومع ذلك، يمكن تحسين الدراسة من خلال زيادة حجم العينة لتكون أكثر تمثيلاً للسكان. كما يمكن أن تكون هناك حاجة لمزيد من الدراسات التي تقارن بين هذه الطرق وأجهزة الزرع السني لتقديم صورة أكثر شمولية عن الخيارات المتاحة للمرضى.

Introduction:
While literature demonstrates that the optimum accuracy for final
impressions is obtained with the custom trays, the use of stock trays for silicone impressions appears to be popular if the proper impression technique was used.
Purpo
se:
This in vitro study was done to evaluate the linear dimensional stability of impression made in stock trays and custom trays with different techniques, using poly vinyl siloxane as an impression material.
Materials and methods:
Three different impression techniques was done as follows:
1- Putty wash 1- step technique using stock tray
2- Putty wash 2- step technique using stock tray
3- 1-step technique using custom tray
For each technique, fifteen impressions of a maxillary partial edenulous metal master model were made and then poured. The accuracy was assessed by measuring five dimensions on stone casts poured from impressions of the master model, then these measurments was compared with the measurments of the linear dimensions of the master model.
Results:
Although the first technique was the most accurate, the statistical analysis showed statistically insignificant difference among the three different impression techniques for the stability of the linear dimensions.
Conclusion :
Making custom tray is time consuming and costly; therefore putty wash 1-step technique in adapted stock trays can be used as an alternative to provide accurate impressions, as obtained from custom trays .
the purpose of this study to evaluate early implant success of small-diameter
2.5mm one-stage dental implants immediately loading in congenital missing of maxillary lateral incisor
cases associated with limited interdental space and mesial and distal bone loss after one year of loading.
Chin area is considered as a suitable donor site for autogenous
bone grafts for alveolar ridge reconstruction before dental implantation.
Despite the common use of chin bone grafts, some neurosensory deficiency
of the of the lower lip, chin area ,
gingiva and lower anterior teeth may
occur.
Purpose: Evaluation of neurosensory deficiency of the lower lip, chin area ,
gingiva and lower anterior teeth following chin bone harvesting for
posterior mandibular alveolar ridge reconstruction.

Low-resource languages can be understood as languages that are more scarce, less studied, less privileged, less commonly taught and for which there are less resources available (Singh, 2008; Cieri et al., 2016; Magueresse et al., 2020). Natural Langu
age Processing (NLP) research and technology mainly focuses on those languages for which there are large data sets available. To illustrate differences in data availability: there are 6 million Wikipedia articles available for English, 2 million for Dutch, and merely 82 thousand for Albanian. The scarce data issue becomes increasingly apparent when large parallel data sets are required for applications such as Neural Machine Translation (NMT). In this work, we investigate to what extent translation between Albanian (SQ) and Dutch (NL) is possible comparing a one-to-one (SQ↔AL) model, a low-resource pivot-based approach (English (EN) as pivot) and a zero-shot translation (ZST) (Johnson et al., 2016; Mattoni et al., 2017) system. From our experiments, it results that the EN-pivot-model outperforms both the direct one-to-one and the ZST model. Since often, small amounts of parallel data are available for low-resource languages or settings, experiments were conducted using small sets of parallel NL↔SQ data. The ZST appeared to be the worst performing models. Even when the available parallel data (NL↔SQ) was added, i.e. in a few-shot setting (FST), it remained the worst performing system according to the automatic (BLEU and TER) and human evaluation.
