NCT ID: NCT06155799 Recruiting - Dental Implants Clinical Trials

Accuracy of Dynamic Navigation System on Zygomatic Implant Placement

Start date: November 15, 2022
Phase: N/A
Study type: Interventional

This study consists in a randomized controlled trial which objective is to assess the accuracy of a dynamic navigation system in zygomatic implant placement in partially or total edentulous patients in the upper jaw compared with the conventional freehand method.

NCT ID: NCT05672056 Recruiting - Clinical trials for Surgery, Computer-Assisted

Novel Application of a Low-cost Alternative to Patient Specific Implants (PSI) in Mandibular Free Fibula Flap Reconstruction by Reverse Engineering of Stock Plates: A Pilot Validation Study

Start date: May 2023
Phase: N/A
Study type: Interventional

Stock reconstruction plates have been used for decades and represent a tried-and-true alternative to custom plating. Stock plates are readily available, are cost effective, and can be accurately bent before surgery, particularly when using stereolithographic models. Unfortunately, the use of stock plates typically precludes the utilization of predictive holes; this can make inset more difficult as the plates do not precisely match the native mandibular contour. Previous descriptions of fabricating predictive holes with stock plates have been inaccurate and inefficient. We aim with conducting this research to improve on the ability of pre-bent stock plates of reproducing the VSP in the operating theater allowing accurate native mandible fixation, accurate fibular segments harvest and accurate inset of the reconstruction in lieu of using the expensive alternative of PSI, thus expanding the use of VSP in mandibular reconstruction in resource limited institutions.

NCT ID: NCT05512845 Completed - Dental Implants Clinical Trials

The Double Factor Technique: a Computer-guided Implant Surgery Technique for Fully Edentulous Patients

DoubleFactor
Start date: September 1, 2021
Phase:
Study type: Observational [Patient Registry]

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.

NCT ID: NCT05325060 Completed - Clinical trials for Arthroplasty, Replacement, Knee

Navigated Versus Convention Total Knee Arthroplasty

iNAV
Start date: June 25, 2007
Phase: N/A
Study type: Interventional

The aim of this single blinded randomised control trial study was to assess the accuracy of implantation of components and the clinical outcome and complications with the iNAV electromagnetic navigation system compared with conventional techniques. Secondary outcome measures include Patient reported outcome measures (PROMS) and rates of revision surgery up to 10 years post operatively.

NCT ID: NCT04344808 Not yet recruiting - Dental Implants Clinical Trials

Dynamic Navigation System in Implantology

Start date: April 2020
Phase: N/A
Study type: Interventional

This study consists in a randomized controlled trial which objective is to assess the accuracy of a dynamic navigation system in dental implant placement in partially edentulous patients compared with the conventional freehand method.

NCT ID: NCT03854162 Completed - Dental Implants Clinical Trials

A Study of a Surgical Guide for Dental Implantology

Start date: August 17, 2018
Phase: N/A
Study type: Interventional

This is a prospective, adaptive, parallel study with four arms, which seeks to compare the accuracy of freehand and guided dental implantation surgeries. The basis of the comparison in each case is a digital plan, and that digital plan is compared to the actual postoperative status by computerized, three dimensional analysis.
