NCT07211022
This clinical trial evaluates the accuracy of two digital impression techniques intraoral photogrammetry and intraoral scanning in patients rehabilitated with full-arch implant-supported prostheses (All-on-4 and All-on-6 concepts).
NCT07290322
The goal of this clinical trial is to evaluate denture retention in intra-orally scanned versus extra-orally scanned digitally printed maxillary dentures in completely edentulous patients. The main question is : 1. Do intra-orally scanned dentures provide better retention compared to extra-orally scanned dentures? Researchers will compare the intra-orally scanned denture group to the extraorally scanned denture group to determine if one method leads to superior retention records. Participants will: • Receive both types of dentures (intra-orally scanned and extra-orally scanned), with a three-week wash-out period between each intervention. The study aims to provide evidence on the optimal scanning method for digitally printed maxillary dentures in edentulous patients.
NCT05464914
In the first part, after a brief introduction, the advantages and disadvantages of immediate dentures are compared. There is a detailed discussion on assessment and treatment planning which includes history taking, examination of the soft and hard tissues, current prostheses, occlusion as well as discussion on investigations required and formulating a diagnosis. The first part ends with a summary of types of immediate dentures and denture designs.
NCT06881199
Conventional dentures can be uncomfortable and limit oral functionality due to the polished surfaces covering the palate and rugae areas. A randomized crossover clinical trial was conducted to compare patients' satisfaction and oral health-related quality of life when using dentures with an acrylic or metal palate. The study aimed to determine whether an acrylic palate would provide better sensory feedback and improved oral function. Participants wore each denture and completed a questionnaire. The study's results have implications for the design of complete dentures, as they highlight the importance of considering patient experiences and feedback when selecting materials. By prioritizing patient satisfaction and oral health-related quality of life, dental professionals can enhance denture treatments' effectiveness and improve patients' quality of life.
NCT06846619
The goal of this clinical trial is to evaluate patient satisfaction with intra-orally scanned versus extra-orally scanned digitally printed maxillary dentures in completely edentulous patients. The main questions it aims to answer are: 1. Do intra-orally scanned dentures provide higher patient satisfaction compared to extra-orally scanned dentures? 2. Are there significant differences in comfort, fit, aesthetics and phonetics between the two types of dentures? Researchers will compare the intra-orally scanned denture group to the extra-orally scanned denture group to determine if one method leads to superior patient-reported outcomes. Participants will: * Receive both types of dentures (intra-orally scanned and extra-orally scanned), with a three-week wash-out period between each intervention. * Complete satisfaction surveys to assess comfort, fit, and aesthetics after using each type of denture. The study aims to provide evidence on the optimal scanning method for digitally printed maxillary dentures in edentulous patients.
NCT05972538
A Total number of 36 implants were installed in 6 patients having mandibular single denture. The patients were divided into two groups according to the definitive prosthesis. Group I received ball and socket retained mandibular implant overdenture while Group II received cement retained implant supported fixed bridges.
NCT04999579
Bite testing using T-Scan allows the evaluation of occlusal contacts prior to making a bite adjustment. The T-Scan can indicate premature contact and the load distribution on teeth, and provide measurable force and time information that ensures proper occlusal adjustment.
NCT04942262
80 complete denture (CD) wearers participated in the quasi-experimental study. Two outcomes were: 1) oral health-related quality of life (OHRQoL) assessed using the Oral Impacts on Daily Performances index, and 2) masticatory performance, determined by a peanut particle size after 20-stroke mastication. Denture retention and stability were evaluated using the Chulalongkorn University (CU)-modified Kapur method to classify the CD into acceptable or unacceptable quality. Data were collected at 3-time points: 1) at baseline (T0), 2) after a 1-month trial of denture adhesive (DA) use (T1), at which time the participants decided whether to continue using DA, and 3) 1-month after continued or discontinued using DA (T2).
NCT03048812
Dental implants are often the preferred treatment option and in some clinical scenarios they are considered the standard of care to restore missing or damaged teeth, due to the limitations of conventional treatments. For fully edentulous subjects, conventional tissue-supported dentures in some cases are associated with severe subjective complaints and difficult adaptation, mainly the mandibular denture, resulting in limited function and detrimental effects on oral health-related quality of life, especially for older patients. The use of implants to retain a mandibular denture (overdenture) has been recommended as a suitable and low-cost alternative to improve denture stability, with positive effects on oral comfort and function. The two-implant mandibular overdenture has been considered an effective design to achieve clinical benefits for patients. However, the main problem facing two-implant overdenture is the high cost of implantation and the relative complexity of the surgical intervention, so the use of a single midline implant to retain a mandibular overdenture was suggested as a more viable solution for reducing costs and complexity of treatment with similar benefits compared to solutions with higher number of implants. Nevertheless, there are few studies that compared the performance of different retention systems and their effects on patient-centered outcomes, such as satisfaction with the dentures, oral health-related quality of life, individual preferences and other subjective ratings of clinical outcomes. Thus, the aim of this randomized clinical trial with a crossover design is to investigate the changes in clinical and patient-reported outcomes following the use of different retention systems for a single implant-retained mandibular overdenture Hypothesis: it was hypothesized that clinical and patient-reported outcomes of a single-implant mandibular overdenture is dependent on the type of retention system, and patients have distinct preferences in relation to different attachments
NCT03326453
The better form of ridge will provide using wider implants that can have better abilities to with stand forces and to prevent alveolar bone loss as much as possible. Ridge expansion gained some popularity due to easiness compared to any other procedure that can gain bone. However, this treatment modality needs to be evaluated as compared to Mini Dental Implants (MDIs) over denture in thin mandibular ridge. In mandibular edentulous patients having thin ridge, does the mini implant supported over denture, compared to the conventional implant supported over denture after bone expansion affect bone height around implants?

Randomized clinical trial to compare between biting force of mandibular complete denture constructed from two different materials; metal reinforced polyamide and conventional PMMA,The null hypothesis of the study that there will not be a difference between biting force of the complete denture constructed from metal reinforced polyamide and PMMA
NCT01397617
The purpose of this study is to determine the survival rate, marginal bone resorption, soft tissue health and maintenance of the NobelActive Internal and External implants and to make comparisons with the NobelReplace Tapered Groovy implant placed in healed sites.
NCT02180230
The aim of this study was to evaluate the 7 mm long implants NobelSpeedy Shorty and Brånemark System Mk III Shorty: by determining the marginal bone remodeling, implant survival rate, soft tissue health and maintenance.
