Purpose: This study aimed to determine the effect of metal base removable partial dentures (MRPDs) and acrylic base removable partial dentures (ARPDs) on oral health-related quality of life. Design/methodology/approach: The study was conducted on 40 patients. Twenty received ARPDs (nine in the maxilla and eleven in the mandible), and twenty received MRPDs (nine in the maxilla and eleven in the mandible). The patients were 45–65 years old. The impact of RPDs on the patient's quality of life was analysed with the Oral Health Impact Profile (OHIP-ALB14) questionnaire. The differences in OHIP-14 between the two dentures at three different time points were estimated. All statistical analyses were performed using SPSS software, version 22 (IBM), and a p-value<0.05 was considered statistically significant. Findings: The OHIP-ALB14 score for both denture types was high at T1 and then remarkably decreased at T2 (p<0.05) and T3 (p<0.05), with no significant differences between MRPDs and ARPDs users. For ARPD users, the satisfaction level significantly increased (<0.001) after one year for the dimensions of Physical Pain, Functional limitation, and Psychological Discomfort. Whereas, for MRPD users, satisfaction level significantly increased (<0.001) in the dimensions of Functional limitation, Psychological Discomfort, and Psychological Disability after a year of denture use. Research limitations/implications: The findings from this study can be taken as the first step towards future research with a longer post-operative follow-up that can analyse the differences between dentures if any. Practical implications: The comparative analysis between ARPD and MRPD and their impact on the oral soft tissues will help prosthodontists reach accurate treatment decisions. Originality/value: This study has not been conducted in the region of Kosovo before. Moreover, the engineers manufacturing dental prostheses will know about the effect of their product on oral health.

Purpose: The goal of this article is to present the developed methodology of computer-aided designing and manufacturing of removable partial dentures on the example of the free-end situation in the mandible. Design/methodology/approach: The method of designing and manufacturing of removable partial dentures was developed on the basis of real clinical data coming from a patient with a free-end situation in the mandible. The method is focused on completely virtual designing of the partial dentures made of titanium and chrome-cobalt alloys covered with aesthetic acrylic material. Findings: The CAD/CAM produced prosthesis adheres tightly to the tissue improving its stability, retention and evenly transferring loads on the tissue, causing less interference in the oral mucosa. Research limitations/implications: The development of the precise design procedures, including CAD/CAM, for fabrication of partial dentures is justified because there is still a large group of patients who would benefit from improving the accuracy of these solutions. Practical implications: The development of the precise design procedures, including CAD/CAM, for fabrication of partial dentures is justified because there is still a large group of patients who would benefit from improving the accuracy of these solutions. Originality/value: This paper presents an original method of designing and manufacturing of removable partial dentures. This allows for precise planning of the shape of the denture frame in relation to individual anatomy of the teeth and the soft tissue of the oral cavity. The execution of the CAD/CAM technology allows to avoid changes of the volume and shape of the prosthesis that is very common in conventional manufacturing procedures.
