Filter by:The aim of the study is to prospectively evaluate the survival of JJGC Cobalt-Chromium (CoCr) prosthetic abutments in single-unit implant-supported prostheses, to confirm the long-term safety and performance of the devices.
Hybrid Funnel Technique arises from the union of subtractive and non-subtractive techniques for implant site preparation. Hybrid funnel technique is performed with specially designed drills and osteotome. the aim of the study is to examine marginal bone level and implant stability of implants inserted with two different techniques for the surgical implant site preparation.
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)
Two hundred individuals will be formed according to the study and control groups: Group-1: coronavirus 2 (Covid-19) (+) patients (n=100) and Group-2: Healthy individuals (in which the volunteers will be included due to group-1) (n=100). Oral examinations including DMFT scores, salivary flow rate, visible gingival index scores and radiographs (OPG) will be performed on both groups on the 1st appointment. Oral swap samples will be collected with sterile swap brushes (Six sample for each person) on the 1st, 7th and 30th days to evaluate the salivary immunoglobulins (Immunoglobulin A (IgA), Immunoglobulin G (IgG), Immunoglobulin M (IgM)) and cytokine (IL-1, IL-6, IL-10) levels. Blood samples will be collected to validate the oral swap test results.
Until now, limited research has observed the stability of photo functionalized sandblasted acid-etched (SLA) titanium implants. The study includes a sample size of sixty otherwise healthy patients with implant replacement, comparing nonirradiated, irradiated UVA and UVC titanium implants. It was an interventional study with a sample size divided into three groups using simple randomization. Patients with nonirradiated dental implants make the control group A with UVA and UVC dental implants forming groups B and C, respectively. Before functional loading, implant stability was measured on days zero and eight weeks. SPSS 26.0 is used for data analysis. The data for implant stability quotient (ISQ) levels and osseointegration speed index (OSI) were presented as mean ± SD for each group. The effect of UVA and UVC on ISQ2 compared with the baseline ISQ was done by applying multiple simple regression analysis models, whereas the distinction between UVA and UVC was made through a t-test. p ≤ 0.05 was kept statistically significant. The implants irradiated with UVA significantly affected ISQ levels compared to other groups.
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.
Effect of Topical Application of Hyaluronic Acid on Stability of Immediate Loading Dental Implant in Posterior Maxilla
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.
- 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.
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.
