Introduction: Utilization of removable partial dentures (RPD) is inevitable in some patients that are not indicated for any other treatment option, thus patient satisfaction with this line of treatment is of great importance. However, a notable need exists to advance materials and fabrication technologies due to the undesirable health outcomes linked with current RPDs. Aim: In this study patient satisfaction with conventionally manufactured metal RPD framework, was compared with their satisfaction using digitally milled PEEK (Juvora) framework. Methods: Ten patients were selected having class I partially edentulous mandibles. A conventional metal framework RPD was constructed for each patient, then another RPD with milled PEEK framework was digitally fabricated for each one of them. Each patient had the chance to use each denture for three months, then questionnaires were filled to assess their satisfaction. Results: The questionnaires were statistically analyzed and resulted in more patients' satisfaction with the digital PEEK framework RPD, than with conventional metallic RPD framework. Conclusion: PEEK material increases patients' satisfaction with RPDs than the conventional metal framework material, thus decreasing patients' complaints from removable appliances.

Background: Denture base materials are subjected to sorption, a process of absorption and adsorption of liquids depending on the environmental conditions, also their fitting surface is subjected to microbial adhesion due to surface irregularities. Soft silicon liners are usually used with removable appliances to decrease load concentration on the hard and soft tissues. Silicon liners also undergo fluid sorption and microbial adhesion. Aim: This study was carried out to assess the effect of standardizing the oral hygiene conditions on the microbial load difference between conventional acrylic denture bases and silicon soft relining material (Mucopren soft) used to reline mandibular complete dentures in atrophied mandibles. Methods: Conventional complete dentures were constructed for 25 patients with flat atrophic mandibular ridges to be used for two weeks, salivary swabs were collected to evaluate oral flora attached on the fitting surface of the denture base and the buccal vestibule, soft liner was applied for all patients mandibular denture surfaces and the same approach was repeated after two weeks of the liner use. Results: Microbial load was found to be significantly higher in the fitting surfaces of the silicon soft liner, than in the conventional acrylic base fitting surfaces. Conclusion: Even under controlled oral conditions, Mucopren soft silicon liner incorporates greater microbial load than acrylic material thus, subjecting patients to numerous infections.

Edentulism prevalence is high in many developing countries, which dictates replacement with a convenient restoration. Meeting patients' expectations and fulfilling their demands is the supreme criterion for complete denture satisfaction. Appearance and efficiency are the ultimate predominant factors. Patient satisfaction is the key to good quality of life which is a human's birthright.The aim of this study is to identify the preponderant dimension of patient satisfaction, with special concern for patient perception toward the dentist's experience and professionality.Methodology: 116 completely edentulous patients were selected from the outpatient clinic, 58 patients (group I) had their dentures constructed by dental students, and 58 (group II) had their dentures constructed by prosthodontists. A questionnaire-based survey was utilized to detect patients' satisfaction with their dentures and recognize if there was a difference in satisfaction scores among the two groups.Results: Patients were generally satisfied with their dentures, and most of them had the highest level of satisfaction with denture esthetics and the lowest satisfaction score with eating difficulties. As for satisfaction difference between groups I and II, there was no significant difference found among both groups. Conclusion:It was concluded that the most common problem experienced by the patients generally was eating difficulties followed by retention problems, then other miscellaneous problems, pain and discomfort, and finally esthetics. As for the difference in the overall satisfaction level among both groups, there was no significant difference between patients treated by dental students and those treated by specialized prosthodontists.
