Abstract
AIM OF THE STUDY To assess the awareness and practice of Immediate Dentures among the dentists who work in the private clinics in Khartoum state, Sudan Materials and methods: A descriptive cross-sectional questionnaire-based study was conducted among the dental medical officers, registrars, specialists, and consultants who are working in private clinics and centers in Khartoum state and registered the private medical institutions in Sudan. The sample population was 664, using the stratified sampling technique and simple randomization within the stratum, 265 dentists were asked to participate in the study voluntarily A self-administered questionnaire consisted of 32 closed questions and 3 sections, section (1) involved the participant's data, section (2) contained the participant's knowledge, and section (3) the participant's practice was distributed. The participant's knowledge and practice scores were calculated as percentages achieved by dividing the number of accurate answers of the participants by the total number of questions and categorized as Good (66.6-100%), Average (33.3-66.6%), and Poor (less than 33.3%) Data was collected and analyzed using a statistical package of Social Science (SPSS) computer software version 22. Chi-square was used for statistical analysis Results: The response rate was 100%, with nearly equal distribution between males (135, 50.9%) and females (130, 49.1%). The age range is 24-39 years, with a mean of 31.65 ± 7.52 years. The majority of the participants (172, 64.9%) were freshly graduated and young practitioners, with the majority of them having experience ranging from 1 to 6 years. The result of the study revealed that 65.7% of the respondents have average knowledge about immediate denture while 8.7% expressed poor knowledge and only 25.7% had excellent knowledge On the other hand, the majority of the participants (200,75.5%) have never constructed an immediate denture, while only 21.1% have a history of constructing 1-5 immediate dentures, 3% constructed more than 5-10 immediate dentures and only 0.4% constructed more than 10 immediate dentures The lack of knowledge and experience was the main barrier preventing the use of immediate dentures, and the mainstream of the participants (118, 44.5%), evaluated their knowledge about the immediate denture as poor Using the Chi-square test, the correlation between the participants' knowledge and their gender, years of experience, and qualification was found not significant (p -values of 0.46, 027, and 0.66, respectively) while a significant correlation was found between the participants' self-evaluation of their knowledge and their knowledge score with a p-value of 0.000* Conclusion: Within the limitations of this study, the dental practitioners have average knowledge about the immediate denture, but the practice of the immediate denture is still very limited and requires enhancement Clinical significance: Immediate dentures have a significant role in maintaining the patient's esthetics, phonetics, masticatory efficiency, self-esteem, and quality of life. Hence, the knowledge and practice of the different dentists about the immediate denture are of great importance to improve the standard of care provided for the patient Keywords: Dentists, Immediate denture, Knowledge, Practice.

Abstract
In patients with severe tooth mobility, conventional impression making can be challenging because of the risk of accidental tooth extraction. Digital intraoral scanning avoids such a complication but does not capture optimal border extensions for a complete denture. This clinical report presents a combined digital and analog recording technique which allows the recording of optimal vestibular border extensions without the risk of tooth extraction.

Abstract
PURPOSE To improve the clinical effects of complete denture use and simplify its clinical application, a digital complete denture restoration workflow (Functional Suitable Digital Complete Denture System, FSD) was proposed and preliminary clinical evaluation was done. MATERIALS AND METHODS Forty edentulous patients were enrolled, of which half were treated by a prosthodontic chief physician, and the others were treated by a postgraduate student. Based on the primary impression and jaw relation obtained at the first visit, diagnostic denture was designed and printed to create a definitive impression, jaw relation, and esthetic confirmation at the second visit. A redesigned complete denture was printed as a mold to fabricate final denture that was delivered at the third visit. To evaluate accuracy of impression made by diagnostic denture, the final denture was used as a tray to make impression, and 3D comparison was used to analyze their difference. To evaluate the clinical effect of FSD, visual analogue scores (VAS) were determined by both dentists and patients. RESULTS Two visits were reduced before denture delivery. The RMS values of 3D comparison between the impression made via diagnostic dentures and the final dentures were 0.165 ± 0.033 mm in the upper jaw and 0.139 ± 0.031 mm in the lower jaw. VAS ratings were between 8.5 and 9.6 in the chief physician group, while 7.7 and 9.5 in the student group; there was no statistical difference between the two groups. CONCLUSION FSD can simplify the complete denture restoration process and reduce the number of visits. The accuracy of impressions made by diagnostic dentures was acceptable in clinic. The VASs of both dentists and patients were satisfied.

Abstract
Digital technologies use high-precision three-dimensional scanning, intelligence-aided design software, and multi-axis numerical control milling or 3D printing, which can produce restorations with reliable precision and suitable function. However, the development of digital technologies in the field of complete denture restoration has been slow due to the complexity of prosthesis. This review article introduces the current research status and clinical applications of digital complete dentures in prosthodontic clinics and dental laboratories to provide beneficial references to prosthodontists and dental technicians.

Abstract
Most digitally fabricated removable dentures are currently available in resin only. To overcome this limitation, digitally fabricated dentures were designed by using a general purpose software program rather than a dental computer-aided design (CAD) software program. The functional cusps were made in metal and the denture base in resin with a 3-dimensional (3D) printer. The 2 outputs were combined to complete the metal-containing digitally fabricated dentures. The technique provides new possibilities for making a variety of digital dental prostheses.

Abstract
BACKGROUND Incisor loss constitutes a strong aesthetic and psychologic traumatism for the patient and it remains a challenging situation for the dental practitioner because of the necessity to rapidly replace the lacking tooth. Various therapeutic procedures have been proposed to replace the incisor concerned, for example by using a removable partial denture. However, the manufacturing of such a denture with classical procedures is often subject to processing errors and inaccuracies. The computer-aided design and computer-aided manufacturing (CAD-CAM) technology could represent a good alternative, but it is currently difficult because of the lack of dental softwares able to design easily immediate removable partial dentures. CASE PRESENTATION A 30-year- patient complained about pain caused by a horizontally and vertically mobile maxillary right central incisor. After all options were presented, extraction of the traumatized incisor was decided due to its very poor prognosis, and the patient selected the realization of a removable denture for economic reasons. The present paper proposes an innovative procedure for immediate removable denture, based on the use of an intraoral scanner, CAD with two different softwares used sequentially, and CAM with a 5-axis machine. CONCLUSIONS We show in this report that associating an intraoral scanner and CAD-CAM technology can be extended to immediate dentures manufacturing, which could be a valuable procedure for dental practitioners and laboratories, and also for patients.
