The purpose of this study is to investigate the efficacy and safety of the Ahmed valve implant (AVI) and the Molteno single-plate implant (MSPI) in eyes with refractory glaucoma during a follow-up period of 24 months.
Outcomes of subjects with uncontrolled glaucoma with a single existing aqueous tube shunt implant undergoing a second aqueous shunt to transscleral diode laser cyclophotocoagulation.
The objective of this study is to compare the long-term safety and efficacy of the Ahmed and the Baerveldt implants in patients who are undergoing aqueous shunt implant surgery for glaucoma. Eligible patients will be randomized. Outcome measures include intraocular pressure, visual acuity, visual field, number of glaucoma medications, glaucoma reoperations, and complications, including suprachoroidal hemorrhage, endophthalmitis, choroidal effusion, diplopia, corneal edema, and...
Comparison of Ahmed Glaucoma Implant (AGI) against trabeculectomy with mitomycin C in patients with uncontrolled open angle glaucoma
The purpose of this study is to determine if an implant material can be injected to repair nasal valve collapse.
This is a prospective, interventional, multi-center trial to report the overall incidence of reduced leaflet motion identified by CT imaging in patients receiving a commercially approved LivaNova bioprosthetic aortic heart valve up to 1 year post implant.
The objective of this prospective clinical trial is to compare the esthetic and radiographic outcomes following immediate implant placement with or without labial plate dehiscence defects using bone augmentation in combination with an absorbable collagen membrane.
Immediate tooth replacement with implants into extraction sockets has become a common clinical procedure regarding implant survival, osseointegration and esthetics. Basically, when there is a labial bone plate loss after extraction 2 stage GBR procedure would be carried out to allow adequate amount of bone formation to be reconstructed and receive the dental implant. The challenge is when there is a partial or complete loss of labial plate of bone resulting from severe ...
This study will evaluate LNG-IUD and ENG implant users who are willing to use their contraception beyond the end of the FDA-approved duration. Implant users will also be offered to participate in an arm of the study that will randomize them to either keeping their implant in or have it removed and replaced with a new implant. Participants will be followed for up to three years.
This research is being done to compare the safety and effectiveness of two sizes of the Baerveldt glaucoma implant. A Baerveldt glaucoma implant is one of the most common types of glaucoma operations performed. This procedure works by providing a route by which fluid can drain out of the eye to decrease the intraocular pressure. The Baerveldt implant does this by placing a tube into the eye which shunts aqueous fluid to a silicone plate which is attached to the sclera ...
The main objective is to evaluate peri-implant hard and soft tissues's stability with the use of a ceramic implant (Implant Straumann®Pure Ceramic) during one year follow up.
The purpose of this study is to compare the safety and efficacy of the Ahmed Valve and the Baerveldt Tube in treating refractory glaucoma. Eligible patients will be recruited from multiple study centers and randomized to a glaucoma drainage device for implantation. They will be followed long-term based upon outcome measures including intraocular pressure, glaucoma medication use, visual acuity, complications of the surgery and further treatments required.
The objective of this randomized controlled clinical trial is to evaluate the increase of soft tissue thickness around single implants installed in maxillary esthetic area with the use of Leucocyte-Platelet rich Fibrin (L-PRF) membranes. The sample is of 42 individuals, where the control group (n = 21) will receive single implant placement only, while the test group will receive single implant placement with L-PRF membranes.
The primary objective of the LATERA RCT is to demonstrate the superiority of the Latera Implant to improve nasal breathing, compared with a Sham Control procedure.
The purpose of this study is to evaluate the esthetic outcomes following immediate implant combined with the autogenous tissue graft or acellular dermal matrix compared to immediate implant alone.
The present study aims to evaluate the clinical outcomes of immediate implant placement with or without connective tissue graft in patients with small dehiscence buccal bone. Previous studies have demonstrate the intact buccal bone plate plays an important role in the stability of peri-implant soft tissue around immediately placed implants. However, it remains controverisal whether soft tissue stability could be achieved in immediate implant placement with or with connective ti...
A single center, prospective clinical trial is planned to investigate the effect of different emergence angles of implant restorations on peri-implant soft tissue recession and implant marginal bone loss. The primary outcome is to systematically evaluate the association of implant-, peri-implant tissue-, and restoration-related factors with facial mucosal level changes.
Objective: This study investigated how patients' knowledge, attitude, and perceptions influence their oral hygiene practices as well as peri-implant health. Materials and Methods: Participants with single implant crowns placed in 2007-2011 completed a questionnaire that examined their knowledge, attitude, and perceptions on oral hygiene practices and peri-implant health before receiving a periodontal examination, prophylaxis, and oral hygiene education. Clinical parameters reco...
The management of neovascular glaucoma (NVG) is a challenge for the ophthalmologist and surgery is frequently needed to control IOP. The success rates of a drainage device is usually lower in NVG than in other forms of glaucoma. Triamcinolone intra-vitreous injections acetate has been used to treat macular edema secondary to diabetic retinopathy and central retinal vein occlusion and also to control inflammation in ophthalmologic surgeries. In the present study we will c...
The primary purpose of this study is to evaluate the use of the next generation applicator and its instructions for proper insertion of the Radiopaque Implant. Secondary objectives include: evaluation of implant removal, evaluation of the overall contraceptive efficacy and safety of the Radiopaque Implant, assessment of x -ray visibility of the Radiopaque Implant, and to assess subject expectations and satisfaction with the Radiopaque Implant.
This is prospective, non-randomized, single-arm study to assess the safety and effectiveness of lowering intraocular pressure with the Brown Glaucoma Implant. A total of 50 subjects will be enrolled at three centers. Subjects will be followed for 12 months, with the primary assessments completed 6 months after implant.
Data on the interaction between the etonogestrel (ENG) implant and antiepileptic drug (AED) regimen are scarce. We will evaluated the effect of 2 AED regimens (1 including carbamazepine and the other topiramate) on the pharmacokinetic (PK) parameters of an ENG-releasing implant in women with epilepsy.
We test the working hypothesis if 4 weeks of systemic antibiotic treatment in implant-related orthopaedic infections is non-inferior to 6 weeks after complete removal of the infected implant. Randomization 1:1.
This is a prospective, non-randomized, single-arm early feasibility study to assess the safety and feasibility of lowering intraocular pressure with the Brown Glaucoma Implant. A total of 10 subjects will be enrolled at a single center. Subjects will be followed for 24 months, with the primary assessments completed 6 months after implant.
Implant placement may trigger bone trauma, which might result in 3-dimensional bone changes. While the process of peri-implant disease is not well understood, implant position within the bony structure might play a role. However, there is no data available on this regard.
