NCT ID: NCT05427006 Recruiting - Missing Teeth Clinical Trials

Post Market Clinical Follow up (PMCF) Medical Device Registry of Z-Systems Zirconia Dental Products: Z-Systems Registry

Start date: July 1, 2022
Phase:
Study type: Observational [Patient Registry]

Commercially pure (CP) titanium is the gold standard to produce dental implants because it has a huge volume of scientific publications over a period of more than 50 years, it is cheap and simple to produce (i.e., making dental implants economically "affordable") and comes in numerous specific designs of screws for various indications. That is why more than 95% of the implant market is dominated by titanium. However, there is an innovation trend to manufacture implants from more inert and biocompatible materials. Ceramic implants represent a valuable alternative for expanding the patient base of clinicians, especially in cases with challenging aesthetic demand. Furthermore, there has been a significant increase in the number of patients requesting metal-free dentistry or bio-holistic implant treatments. In the past, ceramics were often branded as "inferior" quality due to its reputation as being brittle but the growing volume of scientific publications specifically on zirconia are demonstrating that it is comparable in fracture-strength with titanium implants. There is a clear market niche for zirconia implants, especially in cases of: - Aesthetic reconstructions in the anterior region, especially in patients with a thin gingival biotype - Gingival recessions where a white colored implant is a great advantage - For patients with a titanium intolerance/sensitivity - For patients who prefer a bio-holistic/metal-free dental approach. Today, clinicians are asking for long-term clinical results of zirconia as a dental implant material. Therefore, Z-Systems AG is conducting this zirconia dental implant registry. A registry design was chosen because it will capture long-term benefits/risks from clinical routine without patient selection.

Anterior Resin Bonded Restorations for Adolescent

Start date: May 8, 2022
Phase: N/A
Study type: Interventional

a 24 Patients above 12 years old with missing upper incisor were divided into two groups, group 1: 12 patient will be treated by resin bonded bridge (RBB) with no preparation protocol, group 2: 12 patient will be treated by resin bonded bridge (RBB) with minimal preparation protocol. (RBB) retention/survival, patient's speech as well as thermal sensitivity and patient's satisfaction will be evaluated for 12 month at 3,6,9 and 12 month.

Dental Implant Treatment for Two Adjacent Teeth in the Maxillary Aesthetic Region: an Evaluation After 10 Years

2implants
Start date: October 6, 2022
Phase:
Study type: Observational [Patient Registry]

- Background Replacement of two missing adjacent teeth is considered a difficult treatment in implant dentistry and even more challenging if located in the anterior region due to aesthetic demands. As well peri-implant bone contour as soft tissue volume is compromised at start of the treatment and difficult to restore. The question is if this reconstruction will be stable in the longterm. Full-scale evaluation of adjacent implant placement with crown rehabilitation in the aesthetic region with a follow-up of at least 10 years is underreported in this field of implant dentistry. - Main research question The aim of this observational study was to analyze peri-implant bone changes, mucosa levels, aesthetic ratings and patient-reported satisfaction with the maxillary aesthetic region following implant placement with crown restoration after a 10-years follow-up period. - Design (including population, confounders/outcomes) The study design is an observational study of a group of patients with two missing adjacent teeth in the maxillary aesthetic region which was treated 10 years ago with dental implant placement and an implant-supported restorations. Outcomes: primary outcome is the change in marginal peri-implant bone level 10 years after placing the definitive restoration. Secondary outcome measures will be implant and restoration survival and changes in interproximal peri-implant mucosa, midfacial peri-implant mucosal level , aesthetic outcome assessed by means of an objective index and patients' satisfaction using a questionnaire. • Expected results Stable peri-implant bone levels, stable peri-implant soft tissue levels, high implant and restoration survival rate and satisfied patients.

Evaluation of the Abutment Type Following Oral Implants in Terms of the Surrounding Bone Height

Start date: September 2, 2020
Phase: N/A
Study type: Interventional

Compare two different types of abutments (molded abutments and computer-designed 3D printed abutments) in terms of the amount of bone loss, and depth of periodontal pockets around the implant during different periods.

Accuracy of Trephination-based Versus Drilling-based Guided Dental Implant Placement

Start date: December 2022
Phase: N/A
Study type: Interventional

NCT ID: NCT05157009 Enrolling by invitation - Tooth Loss Clinical Trials

Immediate Implant Outcomes With and Without Bone Augmentation

Start date: October 1, 2021
Phase: N/A
Study type: Interventional

To evaluate immediate implant placement feasibility and esthetic outcomes in severely damaged sockets that received simultaneously bone reconstruction (cortical bone shield) and implant placement versus intact sockets that needed no reconstruction and had immediate implant placement.

NCT ID: NCT05118815 Active, not recruiting - Dental Implant Clinical Trials

Peri-implant Tissues on the Galimplant Anti-rotational Slim Abutment.

Start date: February 21, 2022
Phase: N/A
Study type: Interventional

A dental implant is an alloplastic material surgically inserted in a residual bone ridge, mainly with a prosthetic foundation. Nowadays the most widely used implants and with a higher degree of scientific evidence are the titanium root-form endosseous implants. In addition to the root component, the prosthodontic systems that allow the crown to be connected to the implant are very important. The aim of this project is to compare a classic anti-rotational straight esthetic multi-position attachment with the new anti-rotational straight esthetic slim multi-position abutment, both placed at the time of implant surgery. A multicenter randomized single-blind (for the patient) split-mouth randomized clinical trial will be performed to compare the composition, distribution and structure of the peri-implant tissues around the classic straight (control) and Slim (test) intermediate prosthetic abutments of the manufacturer Galimplant (Sarria; Lugo, Spain). The objective is to study which abutment design obtains a better biological seal from the clinical and histomorphometric point of view. For this purpose, 60 dental implants will be placed for the replacement of bilateral posterior absences in 30 patients attending the Master of Oral Medicine, Oral Surgery and Implantology of the University of Santiago de Compostela, Spain.
