Filter by:This retrospective study investigates the longevity of dentures with SR Phonares II teeth after a wearing period of more than 10 years. The primary objective is to assess the survival rate of dentures with SR Phonares II teeth after more than 10 years. The secondary objectives asses the quality of the dentures concerning aesthetic, functional and biological properties.
Introduction: One major complaint frequently voiced by complete denture wearers is denture retention. Conventional denture disadvantage is heat-curing resin deformation. In addition, the pack and press technique that is still more common, residual stresses that occur at the time of packing are released when the material is removed from the flask, causing the resin to shrink, and this shrinkage is cited as a cause of poor fit of the denture base, In the field of prosthetic dentistry, the ability of additive manufacturing to fabricate prosthetic devices based on CAD data influences the overall quality, the mechanical properties of printed parts, the total cost and the manufacturing time. The milling process wastes large quantities of denture base material, and more recent three-dimensional (3D) prototyping promises a more sustainable additive approach by using less denture resin. However, no clinical reports have been published regarding the accuracy of the mucosal surface or denture retention for denture fabricated using conventional techniques compared to those fabricated using additive manufacturing. Aim of the study: Investigate the effect of two techniques of complete denture manufacturing (conventional and 3D printed) on denture retention, trueness (accuracy), and satisfaction. Methodology: Twenty patients will be selected from the outpatient clinic and will be divided into 2 groups, group A for conventional dentures and group B for 3D printed dentures, retention for the two groups will be measured at 0,1 and 3 months, and patient satisfaction will be recorded, and accuracy of the denture base will be measured on the software. The results will be tabulated and statistically analyzed using the SPSS program.
Objectives: The purpose of this study is to evaluate bite force (BF), oral health-related quality of life (OHRQoL), and patient satisfaction in 2-implant-supported overdentures. In addition, the effects of clinical parameters such as age, gender, implant length, implant diameter, locator attachment height, attachment color, and interimplant distance were also evaluated. Material and Methods: A total of 51 patients were included in the study. BFs were measured with a force meter in complete dentures and implant-supported overdentures. OHRQoL was assessed with the Oral Health Impact Profile (OHIP-14) and patient satisfaction was assessed with the Visual Analog Scale (VAS).
Is to compare between the conventional drills versus osseodensification drills for implant stability and peri-implant marginal bone loss in maxillary implant overdenture.
Isolated sinus pneumatization after single tooth extraction indicate sinus lifting for proper implant placement. The conventional way of using osteotomes to elevate the sinus is annoying to patient and also does not give the needed amount of bone around the implant. Introducing new intervention of Densah Burs helps increase bone gain around implant and decrease the patient discomfort.
To overcome the limitations of the current dynamic and static Computer Assisted surgery protocols in fully edentulous patients, and combine the advantages of both approaches, a new technique has been developed, referred to as the "double factor" technique. This study consists in a single arm observational prospective clinical study and the aim was to assess the accuracy and patient's perception and quality of life of the "double factor" technique in treating fully edentulous patients.
In this controlled clinical study, a maxillary sinus lift (crestal approach) with OSSIX® Bone will be performed, and then implants MultiNeO CS (control group) and NINA MultiNeO NH (test group) will be inserted in edentulous posterior maxillae of study subjects. .+the clinical and radiographic results of the rehabilitation of posterior edentulous maxillary areas, obtained with traditional surface implants (MultiNeO CS, control group), are compared with those obtained with bioactive surface implants (NINA - MultiNeO NH, test group ).
In this case-control study a bioactive implant surface was compared with traditional surfaced implants. Primary objectives: Test the implant stability in post-extractive sites, comparing traditional surfaced implants (MultiNeO CS, control group) to bioactive surfaced implants (NINA- MultiNeO NH, treatment group). Primary outcome endpoints were Implant stability, assessed through Implant stability quotient (ISQ) values and Marginal bone loss (MBL)
This study aims to answer the question whether the use of a fluorescent layer over white zirconia abutments will improve the aesthetic outcomes of implant borne single-tooth restorations when compared to the use of non-layered white zirconia abutments. The study is designed as a parallel, single-centre and double blind clinical trial. Patients in need of a single tooth implant in the maxilla (from right second premolar to left second premolar, both included) with the presence of adjacent natural teeth will be randomly divided into two treatment groups: using white yttria-stabilized zirconia abutment (PYRCA; BioHorizons, Birmingham, EEUU) with immersion in fluorescent liquid (Zirkonzahn, South Tirol, Italy)(test group) or white yttria-stabilized zirconia abutment (PYRCA; BioHorizons, Birmingham, EEUU) without immersion in fluorescent liquid (control group). 1 and 12 months after crown placement, patients will be recalled and subjected to aesthetic, clinical, radiographic and patient centered outcomes.
The biggest challenge of oral rehabilitation is the replacement of lost structures and the restoration of their function and esthetics, focusing on matching a healthy tooth. Traditional complete dentures, implant (retained, supported) overdentures, and complete implant-supported fixed prostheses are all alternatives to the rehabilitation of the mandibular arch. The aim of this study was to compare BioHPP used as a skeletal substructure for hybrid (implant fixed, detachable) prostheses versus BioHPP bar supporting and retaining by using radiographic tracing to the marginal bone height changes around the implants, patient satisfaction can be improved.
