NCT ID: NCT04446078 Completed - Dental Implants Clinical Trials

Hybrid Polyetheretherketone (PEEK)-Acrylic Resin Prostheses and the All-on-4 Concept for Full Arch Rehabilitation

AO4PEEKDev
Start date: May 2, 2014
Phase: N/A
Study type: Interventional

It is necessary to evaluate the outcome of implant supported fixed prosthetic rehabilitations using peek material. To test this, the study design to be used will be a prospective single cohort to evaluate the long term outcome of fixed prosthetic implant supported rehabilitations. The cohort will be evaluated after 5 years of follow-up, regarding prosthetic survival, implant survival, marginal bone resorption, incidence of mechanical complications (loosening or fracture of prosthetic components), biological complications (peri-implant pathology, suppuration, fistulae), incidence of biological complications (peri-implant pathology, suppuration, excessive marginal bone resorption) in-mouth comfort, overall chewing feeling, framework integrity, veneer adhesion, veneer chipping, patient tissue reaction, denture staining, manufacture issues,

NCT ID: NCT04304222 Completed - Clinical trials for Dental Prosthesis Failure

Application of 3D Printed Removable Denture Prosthesis Framework for Partial Edentulous Patients

Start date: March 26, 2019
Phase: N/A
Study type: Interventional

Tooth loss is a major dental problem worldwide. A recent study in Singapore found that approximately one third of adults aged over 65 are living without any natural teeth. Prevalence of loss of some teeth, or partial edentulism, in this population is estimated to be even higher. Tooth loss has a series of deleterious consequences for oral and general health. The high prevalence of tooth loss has resulted in great needs and demands of prosthetic replacements, posing challenges to the public dental care system in Singapore. Removable dentures are the most widely and commonly used device to replace missing teeth and restore oral functions. The removable denture possesses a metal framework that connects other components of the denture, to ensure rigidity and stability while in function. However, the current method of fabricating denture frameworks is a complex, error-prone, time-consuming, and expensive process. Due to the inherent inaccuracies in the materials and technique, fit of the framework is compromised and undesirable to meet patients' satisfaction. With the new development of computer aided design and 3D printing metal techniques, it is now possible to apply digital design and manufacturing for the fabrication of dentures. This proposal aims to compare the precision and fit, and patient satisfaction, of 3D printed and conventional casted removable denture frameworks in preclinical and clinical settings.

NCT ID: NCT04274504 Completed - Clinical trials for Survival, Prosthesis

Osteopontin in Metastatic Breast Cancer Patients

Start date: January 2015
Phase:
Study type: Observational [Patient Registry]

OPN plays an important role in various aspects of malignancy, particularly those involved in tissue invasion and metastasis, and OPN levels have been associated with aggressive¬ness in several cancer types, including breast cancer. Tumor response to treatment is a predictor of prognosis and overall survival for cancer patient population the investigators assigned osteopontin as potential contributors in breast cancer.

NCT ID: NCT04272112 Completed - Clinical trials for Dental Prosthesis Failure

Clinical Performance of All-ceramic Posterior Crowns. A Randomized, Prospective Clinical.

Start date: February 1, 2017
Phase: N/A
Study type: Interventional

This is a randomized, prospective clinical trial. The aim of the project is to assess the clinical performance of three types of tooth-supported crowns; monolithic high translucent colored zirconia, crowns of high-translucent colored zirconia with a mini-veneer buccally and crowns of lithium-disilicate glass-ceramic. Crowns will be placed on posterior teeth and evaluated from an esthetic and functional point of view, to identify if there are any differences between the materials.

NCT ID: NCT04244929 Completed - Prosthesis Survival Clinical Trials

Multicenter Perspective Study: Clinical Evaluation of the Persona MC® With Preservation or Sacrifice of the PCL

Start date: December 20, 2019
Phase: N/A
Study type: Interventional

Prospective, multicenter study on the Total Knee Prosthesis available on the market "Persona Medial Congruent® knee". Primary endpoint -Evaluation of the survival of the implant after 5 years of follow-up Secondary endpoints - Evaluation of the survival of the implant at 10 years of follow up. - Evaluation of clinical and radiographic outcomes in Italian patients undergoing total knee replacement with the Persona Medial Congruent® implant with sacrifice or retention of the posterior cruciate ligament (PCL)

NCT ID: NCT03836755 Completed - Amputation Clinical Trials

Evaluation of the Stability of Osseointegrated Implant in Amputees

METACOS
Start date: January 1, 2019
Phase: N/A
Study type: Interventional

The study concerns the technique of osseointegration that consists of inserting a titanium pin into the bone of the amputated limb. A removable external prosthesis will then be connected to the implant section that protrudes from the soft parts. The benefits of using an osseointegrated prosthesis are the improved sensory feedback (osseoperception) and absence of the socket. This leads to better anchoring of the prosthesis to the abutment, greater control of the prosthesis and the absence of heat, pain, and pressure sores. The osseointegrated prosthesis does not reduce the mobility of the limb and promotes good growth of bone and muscle mass. The aim of this study is to evaluate the stability of the osseointegrated implant in trans-femoral and trans-humeral amputees. The main outcome: quantitative evaluation (rotations, translation and MTPM) of the stability of the implant bone interface by Roentgen Stereo-photogrammetric Analysis (RSA) and follow-up. The secondary outcome: evaluation of the quality of life improvement in patients through clinical score and satisfaction survey.

NCT ID: NCT03796494 Completed - Clinical trials for Dental Implant Failed

Peri-implant Tissues on Aesthetic Slim Abutment Galimplant (PSG)

(PSG)
Start date: March 1, 2019
Phase: N/A
Study type: Interventional

This is a randomized, single-blind, split-mouth clinical trial to evaluate the performance of peri-implant tissues (bone and soft tissues) in conventionally loaded Galimplant implants, using a classic multi-position, anti-rotational abutment, comparing it to the new multi-abutment aesthetic slim anti-rotational placed both at the time of the implant surgery. To this end, 80 Galimplant implants with a diameter of 4 mm and 10 mm in length will be placed in areas of mature scarred post-extraction bone. Patients be divided into 2 study groups, group C: straight pillar; Group T: Slim pillar. The bone and clinical radiological stability of the peri-implant tissues will be evaluated at 6 weeks post-surgery and at 6-12 months post-prosthetic loading.

NCT ID: NCT03720236 Completed - Clinical trials for Dental Implant Failed

Peri-implant Tissues in BLX® Implants

BLX
Start date: November 2, 2018
Phase: N/A
Study type: Interventional

This is a randomized triple-blind clinical trial to evaluate the behavior of peri-implant tissues (bone and soft tissues) in BLX implants loaded early or delayed and with different surgical milling protocols. To this end, 40 BLX implants with a diameter of 3.75x10 will be placed in areas of mature bone scarred after extraction. They will be divided into 2 study groups, and these in turn into two subgroups. Group A: complete milling, Group B: partial milling. Each group will be assigned with code 1: early load and code 2: deferred load. Clinical and radiological parameters will be evaluated.
