Purpose: The purpose of this study was to compare elderly patients' satisfaction and oral health-related quality of life with mandibular two-implant overdentures and conventional dentures.
Materials And Methods: Sixty edentulous subjects aged 65 to 75 years were randomly assigned to two groups treated with maxillary conventional dentures and either a mandibular conventional denture (n = 30) or an overdenture supported by two implants with ball retainers (n = 30). Subjects rated their general satisfaction, as well as other features of their dentures (comfort, stability, ability to chew, speech, esthetics, and cleaning ability), prior to treatment and 2 months postdelivery. Changes in ratings on the original Oral Health Impact Profile (OHIP) and its short form (OHIP-EDENT) were also used as indicators of oral health-related quality of life.
Results: The primary outcome of this study, ratings of general satisfaction 2 months postdelivery, was significantly better in the group treated with mandibular two-implant overdentures (P = .001). In addition, the implant group gave significantly higher ratings on comfort, stability, and ability to chew. Furthermore, using OHIP-EDENT, subjects who received mandibular two-implant overdentures had significantly fewer oral health-related quality of life problems than did the conventional group.
Conclusion: These short-term results suggest that mandibular two-implant overdentures combined with maxillary conventional dentures provide better function and oral health-related quality of life than conventional dentures.

Conventional complete denture wearers often complain of lack of stability and overall discomfort with their prostheses. The advent of dental implants and advanced prosthetic methods have greatly improved this struggle for edentulous patients. The utilisation of computer-aided design and computer-aided manufacturing (CAD-CAM) technology has only further enhanced the capabilities of dental practitioners to rapidly and accurately restore edentulism.

Dental implants have revolutionized tooth replacement, offering a functional and aesthetically pleasing alternative to traditional dentures and bridges. While conventional implants, typically titanium screws placed into the jawbone, have become the gold standard, many studies explore non-conventional implant designs and materials to address specific challenges and patient needs. This series of literature reviews aimed to delve into non-conventional dental implants, examining their unique features and applications and the current state of evidence supporting their use.

Purpose: To compare the trueness of the tissue surface of the complete denture base among the digital cutting complete denture, the digital 3D printing complete denture and the conventional complete denture.
Methods: Three edentulous patients were selected, and three complete dentures were made for each case. Cutting dentures (cutting group), 3D printed dentures(printing group) were considered as the experimental groups, traditional dentures (traditional group) were considered as the control group.

Objective: To compare the effectiveness of prosthetic rehabilitation of edentulous patients using conventional complete dentures (CD), single median dental implant retained over dentures (SIMOD) with over dentures retained by two dental implants (TIMOD).
Methods: Thirty completely edentulous patients (fifteen each arm) presented to the Faculty of Dental Sciences, University of Peradeniya were randomly selected for the SIMOD or TIMOD groups. Patients were initially provided with CD.
