Filter by:Previous studies have investigated the outcomes of Knee Arthroplasty (KA) following Bariatric Surgery (BAS), but with substantial limitations as not stratifying for Body Mass Index (BMI) at time of KA or not addressing the type of BAS (gastric bypass, banding or sleeve). Since BMI varies greatly in patients with previous BAS, it is likely that BMI affects outcomes after KA in BAS-operated patients. The investigators believe that stratifying for BMI would explain the contradictions with the previous research in this patient group when it comes to the risk of revision after KA.
REVIVE TAVR is an acronym for the Randomized Evaluation of Valve-In-Valve versus Explantation for failed TAVR. This is a prospective, multicenter, global randomized trial investigating the safety and efficacy of reintervention for transcatheter heart valve (THV) failure by comparing redo-TAVR (TAV-in-TAV) with TAVR surgical explantation (TAVR-explant) in subjects who are suitable for both options in a real-world clinical setting
The all-on-4 treatment approach for completely edentulous mandible is a proven concept. However, there are still issues regarding the use of metal substructure to support the prostheses such as allergy, metallic taste, and aesthetic. Therefore, other materials such as polyetheretherketone (PEEK) are being tested for its suitability and is showing good potential. However, available evidence is limited regarding its clinical performance. Thus, the aim of this study is to compare clinical performance of all-on-4 treatment concept utilizing PEEK versus conventional metal framework as substructure in fully edentulous mandible. Thirty suitable patients will receive either PEEK or conventional all-on-4 prostheses for fully edentulous mandible. The prostheses will be retained by four implants utilizing the all-on-4 principle. Clinical performance will be assessed during the follow up period of up 3 years concerning screw loosening, material chipping or fracture, wear or staining, prosthesis survival and success, implant survival and success.
- This prospective cohort study aims to evaluate the clinical success rate of anterior and posterior full-coverage restorations among a group of Egyptian children treated under general anesthesia. - The main question it aims to answer: In A Group of Children, What Is the Clinical Success Rate of Anterior and Posterior Full Coverage Restorations Performed Under General Anesthesia?
The Intervention Will be All Ceramic Single-retainer Resin Bonded Fixed Partial Denture Using the Upper Canine as Abutment With Minimum Preparation on the Lingual Surface Within the Enamel Providing Maximum Area for the Retainer Bonding, to Replace the Upper Lateral Incisor and Will be Compared With the Control/Comparator Group Which is the All Ceramic Single-retainer RBFPD Using the Upper Central Incisor. The Participants in This Study Will be Recruited by the Researcher From the Clinic of Fixed Prosthodontics Department, Clinic of Orthodontics Department and Clinic of Diagnosis Department, Cairo University Without Any Financial or Non-financial Incentives.
The tracheoesophageal voice with voice prosthesis is currently the mainstay of voice rehabilitation post laryngectomy. The primary surgical technique of tracheoesophageal fistula formation with insertion of prosthesis and quick and easy process of voice rehabilitation are main encouraging factors. However, the usage of the prosthesis relates to a significant number of complications rated from 10 to 60%. The most common reported complication is transprosthetic leakage that determines the need of device exchange. However in some patients occur more serious complications eg. periprosthetic leakage, granulation or atrophy of mucosa around the fistula, dislocation of prosthesis, that may require anti-inflammatory treatment, temporary nasogastric tube feeding or surgical procedure. The standard protocol is voice prosthesis exchange due to transprosthetic leakage. Optionally the device could be replaced regularly to prevent both transprosthetic leakage and other complication occurrence. In the study we plan to compare the benefits from regular (each three month) versus leakage-related exchange of voice prosthesis post laryngectomy including the rate of complications, fistula colonization by Candida species and patients feedback.
When the tooth is severely compromised, it needs a prosthetic crown. The tooth is prepared to allow the housing of the prosthetic crown without difficulty. This study aims to compare two different types of preparations to see with which of the two the gingival tissue reacts best.
In patients receiving implants in the esthetic zone, would the use of new Nano hybrid ceramic crown material (Crystal Ultra) improve esthetic patient satisfaction and peri-implant tissue success when compared with Lithium Disilicate crown (E-max)?
