Filter by:Dental-supported fixed partial dentures (FPDs) have long been a commonly preferred treatment method for the rehabilitation of teeth with excessive substance loss and for addressing existing tooth deficiencies. Crucial factor affecting the success and quality of FPDs is the marginal fit of the restoration. Marginal discrepancy refers to the vertical or horizontal gap between the restoration finish line and the preparation finish line. To achieve high marginal fit restorations, gingival retraction techniques are used with the aim of removing the marginal gingiva away from the finish line. Retraction cords are commonly used for this purpose nowadays. The aim of the study is to evaluate the effect of retraction cords on the preparation finish line and the marginal fit of produced restorations using direct digital measurement methods.
The goal of this observational study is to learn about patients' preference toward the use of customized and connected prosthesis. The main questions it aims to answer are: - What is the acceptability of new customization and connectivity technologies by patients? - Are they all at the same level of acceptability? Participants will have to answer to a questionnaire of choice.
In Latin America, Colombia ranks fourth in countries with the highest number of people with disabilities (6.4%), 80% of whom live in low socioeconomic strata, have little access to education and high unemployment rates. Of these nearly 3 million people with this condition, an estimated 11,476 need upper limb prostheses, 12% of whom have transradial or below-elbow amputation. Although many of the functions that have been lost by amputation can be recovered with a prosthesis, few people in Colombia use these devices. This is because, currently, only aesthetic and mechanical options are found, and the most advanced options, such as myoelectric ones, are manufactured in other countries, have very high prices and are not designed according to local needs. The only option manufactured at the national level is the one developed by Protesis Avanzadas S.A.S., but it still has aspects to improve that would lead it to better adapt to the needs of Colombian users. All of the above shows the evident need for the country to generate products that can help this population. The objective of this project is then to redesign, implement and evaluate the effectiveness of a good quality transradial myoelectric prosthesis, focused on the Colombian amputee population and improving acceptance rates. For the design phase of the study, a group made up of health professionals and patients with transradial amputation will be included to evaluate the preferences and priorities of their prosthesis. For pre-commercial validation, an effectiveness study will be carried out by means of a randomized crossover clinical trial with 12 participants in which the functioning and quality of life of the user with and without the prosthesis and satisfaction with it will be analyzed using methods of Bayesian statistics. This study is expected not only to improve the quality of life of people with transradial amputation and their families, but also to provide a functional option for the health system.
In this prospective randomized four-armed study the investigators aim to compare wheter 3-D planning, which necessitates preoperative CT acquisition and sophisticated planning together with engineers, results in measurable benefits in terms of objective and subjective outcome values in a collective of patients undergoing primary total hip replacement. Hypothesis: 1. When compared to 2-D planning, 3-D planning of a THR results in better hip reconstruction, better subjective and clinical outcome and better longevity of total hip implants. 2. When compared to a non-anatomical stem, an anatomical stem allows better hip reconstruction, better subjective and clinical outcome and better longevity of total hip implants.
This study is designed to learn more about decision making for prosthetic design, with the goal of producing a decision making aid for prosthetic design decisions.
The purpose of this study is to develop criteria for prosthetic foot prescription for Veterans and Service Members with transtibial limb loss. The objectives are to: 1) Determine the appropriate functional outcome tests and measures to support the prescription of a type of Energy Storing and Returning (ESR) non-articulating, articulating or active plantarflexion prosthetic ankle-foot for a Veteran or Service Member with transtibial limb loss. 2) Correlate patient goals and subjective measures with objective data to determine the appropriate prosthetic ankle-foot category that will facilitate the greatest overall function to the user. 3) Develop criteria for the appropriate prescription of non-articulating ESR, articulating ESR, and active plantar flexion ESR ankle-foot units.
