هدف البحث : شملت الدراسة خمسة وعشرين مريضاً وضعوا في ثلاث مجموعـات، و كان هدف الدراسة معرفة تأثير التبطين الطري للأجهزة السنية الكاملـة فـي رفـع الفعالية الماضغة لها. الطرق : تضمنت الدراسة اختبارات سريرية هي : ١ -اختبار الفعالية الماضغة. ٢ -اختبار الظواهر الالتهابية في الغشاء المخاطي الفموي. ٣ -اختبار مدة تعود المرضى على أجهزتهم المتحركة. النتائج : ١ -زادت الفعالية الماضغة باستخدام التبطين الطري للأجهزة بمقدار ( ٢٥,١١ % ) ٢ -حدث شفاء تدريجي للغشائية المخاطية الفموية باستخدام التبطين الطري. ٣ -قلت مدة تعود المرضى على أجهزتهم من ( ٦– ١٠ ) أيام عند اسـتخدام التبطـين الطري . الخلاصة : دلت نتائج الاختبارات على أفضلية واضـحة للأجهـزة السـنية الكاملـة المبطنة تبطيناً طرياً .
The objective of this study was to know the influence of soft denture liners on raising the masticatory efficiency when it is added to base of complete dentures This study included ٢٥ patients ٣ groups . When patients used complete dentures with soft denture liner, masticatory efficiency increased by ١١,٢٥٪ , there was gradual healing (recovery ) of mucous membrane, and the patients needed shorter time (٦-١٠ days) to accept their complete dentures .

Most of prosthodontists know that patient satisfaction is not based only on the
technical quality of the dentures. For that, our study aimed to investigate the influence of some clinical
factors on patients’ satisfaction with conventional complete
dentures. These factors include: patients’
gender and age, smoking, musculature of jaws and cheeks, resorption of mandibular or maxillary residual
ridge, the existence of hypermobile tissues, and previous denture wearing experience.
Many studies were conducted on telescopic
attachments-retained dentures, but only few of them evaluated
masticatory efficiency with that kind of dentures despite the great
importance of this topic. The aim of this study was to evaluate the role
of telescopic attachments in improving masticatory efficiency.
The use of acrylic chairside hard denture lining materials
introduces a lot of benefits; but the effect of these materials on the oral
mucosa was not studied.
The purpose of the research: This investigation was undertaken to
determine the clinica
l and histological changes in the residual alveolar ridge
mucosa when an acrylic chairside hard denture lining material was used.
Background& Objective: Prosthodontists always do their best in order to make dentures that fulfill all the functional and esthetic requirements of the patients. The purpose of this study is to evaluate the relationship between patients’ satisfaction
with traditional complete dentures and clinical measures of denture quality, which include clinical assessment of retention, stability, support, occlusion, esthetics and speech.
Materials & Methods: 104 patients participated in our study (65 males, 39 females). The range of their ages was (40 – 78) years (median=60.9). Traditional complete dentures were made for all these patients, and then they were followed for 4-6 weeks. After that, a questionnaire was filled for each patient. This questionnaire includes questions about patient satisfaction and assessment of the new denture. The clinical measures of quality of the denture were also assessed by a prosthodontist.
Results: The results of this study showed that there was a poor significant relationship between patients’ rating of the retention of their dentures and the clinical measures of retention, stabililty and support (r<0.04). At each of the surveyed situations, the patient considered their dentures better than the examiner
did (P<0.05). There was also a poor, significant relationship between the accuracy of reproduction of
centric relation and the patient ability to masticate with his denture(r=0.27).
Conclusion: Within the limits of this study, it can be concluded that clinical measures of denture quality
affect the retention of the denture as perceived by the patient. They also affect the comfort of the patient during mastication. For that, the dentist must always do his best to make dentures with enhanced quality.
On the other hand, clinical measures of quality are not the only factor that affects the patient satisfaction with denture.
Adapting of the complete denture will ensure its retention. Poly(methyl
methacrylate) is considered to be the best material to manufacture denture bases. However it incurs
changes in dimension and volumetric contraction which affects the adaption o
f dentures and therefore the
retention. The purpose of this study was to compare two types of stone casts in their effect on accuracy of
fit of complete denture base.
