Filter by:Implant supported superstructure is necessary for long term success and durability of the implant itself in terms of stresses distribution and fracture strength capability.1 Stresses falling on an implant are too much greater than those applied on a tooth structure with a periodontal ligament offering a degree of elasticity. The important mechanical and physical properties of materials used for the fabrication of dental prostheses include adequate flexural and tensile strength and modulus of elasticity, maximum fracture resistance, optimal bond strength and adequate polishability.
In the present pilot study, a possible relation between the implantation of PP mesh for inguinal hernia, vaginal prolapse and SUI repair and subsequent systemic auto-immune complaints is investigated by testing immunologic and allergic responses in fifty patients with suspected ASIA syndrome. Additional value of MAT is investigated and effectiveness of (partial) PP mesh removal for these complaints is assessed. If so, a profound insight in diagnostics and treatment for systematic complaints will be attained that may provide opportunities for future diagnostics.
ESSURE® is an implantable medical device for definitive and irreversible sterilization indicated for adult women of childbearing age. These implants are inserted into the fallopian tubes by hysteroscopy. Marketed in 2002, ESSURE® contraceptive implants were withdrawn from the French market in 2017 (and worldwide in 2017 and 2018) following the observation in certain patients of polymorphic and non-specific gynecological and extra-gynecological symptoms. Studies with small numbers and short-term follow-up have shown a significant improvement in these symptoms after implant explantation. This constitutes a real public health problem since according to the report of the EPI-PHARE Scientific Interest Group, 198,000 French women have these implants and only 30,000 of them, or 15%, have been explanted, knowing that explantation of ESSURE® implants is recommended only in symptomatic patients. A large number of these patients, presenting symptoms, have not yet been treated for an explant. The physiopathological mechanism(s) is (are) not yet determined but several arguments are in favor of a dissemination of metallic elements contained in these implants whose accumulation could lead to inflammatory and/or allergic and/or autoimmune phenomena. Carrying out a prospective study with long-term longitudinal follow-up appears essential to precisely assess the degree of improvement in the symptoms and quality of life of these patients, determine the most appropriate surgical techniques, and understand the pathophysiological mechanisms that may result in the implementation of specific treatments and relevant markers. From a surgical point of view, there is a real risk of fracture of implants whatever the type of intervention performed: study the biomechanical properties of implants with a view to characterizing their behavior to mechanical rupture but also their thermal resistance in an objective manner seems essential to limit the risk of fracture and help to inform the patient about the surgical technique proposed for explantation. From a biological point of view, the dosage of the metallic elements constituting ESSURE® implants and potentially toxic ones could make it possible to objectify the release of these metallic elements in the body. Analysis of pro-inflammatory cytokines, micro-RNAs (miRNA), quantitative analysis of inflammatory pathway messenger ribonucleic acid (mRNAs) (NanoString technology) and analysis of neuroinflammation by functional imaging should make it possible to explore potential pathophysiological mechanisms. This study responds to a significant request from patient associations.
The current trial aim was to evaluate clinically and radiographically the changes around dental implants inserted immediately in maxillary anterior esthetic zone using a novel combination of autogenous demineralized tooth graft. with autogenous demineralized tooth plate and compared this approach to autogenous demineralized tooth graft. The present study included 63 patients, aged 20 to 45, with teeth that needed to be extracted. After Kafrelsheikh University research ethics committee approval, patients were randomized into 3 groups: group I patients underwent immediate implantation with Duo-Teck membrane, while group II patients underwent the same procedure, but the dehisced bone defect was grafted by autogenous demineralized tooth graft. finally group III was grafted by combination of autogenous demineralized tooth graft. with autogenous demineralized tooth plate.
For the purpose of the study, patients will be divided into two groups, i.e., Group A and Group B. In Group (A), 14 immediate implants will be placed using traditional drilling technique, while in Group (B), 14 immediate implants will be placed using OD drilling technique Osseodensification is a system for implant osteotomy preparation, it compresses the cancellous bone around the revolving drills. It largely improves low bone volume by physically increasing the interlocking between the bone and the implant surface. The Densah burs enhances bone density while generating the least amount of heat. Traditional oversized drilling is the regular manufacturer recommended technique of drilling. It functions by cutting the bone during osteotomy preparation by sharp fluted drills. The undersizing of the preparation allows the implant to partially compact the bone during insertion. The objective of the current study is to compare between osseodensification drilling protocol versus traditional undersized drilling protocol in immediate implant placement in anterior maxillary region in terms of implant stability.
Aim of the current randomized clinical trial is to evaluate and compare the effectiveness of computer-guided immediate implant placement performed simultaneously with artificial intelligence assisted socket shield technique versus conventional approach.
The current trial aim was to evaluate clinically and radiographically the changes around dental implants inserted immediately in maxillary anterior esthetic zone using a novel combination of autogenous whole tooth graft (AWTG) with socket shield approach (SSA) and compared this approach to socket shield technique with xenograft. The present study included 63 patients, aged 20 to 45, with teeth that needed to be extracted. After Kafrelsheikh University research ethics committee approval, patients were randomized into 3 groups: group I patients underwent immediate implantation using socket shield protocol, while group II patients underwent the same procedure, but the shield/fixture jumping gap was grafted by xenograft. finally group III was grafted by AWTG that was created using the decoronated crown and the extracted palatal portion of the tooth; and then placed in the peri-implant gap defect.
Implant placement in deficient posterior maxilla is a challenging clinical situation that necessitates appropriate treatment options to restore this area. -Aim of the study: To compare allograft vs tenting technique in terms of implant stability and bone height.
Reporting of the reason for implant removal in a hospital setting over 20 years. retrospective design.
This is a single-center, single-group, prospective clinical trial testing a partially-guided protocol for placement of mini implants overdentures in the edentulous maxilla. Eligible participants will be subjects with an edentulous maxilla, wearing a conventional complete denture. Participants will receive six mini implants (Straumann® Mini Implant System, Institut Straumann AG, Switzerland) for retention of a maxillary overdenture. The six mini implant protocol will be virtually planned for an even distribution of the implants bilaterally, with a minimum of 5 mm distance between contiguous implants. The available lengths of the mini implants are 10, 12, and 14 mm, and the appropriate length will be selected according to the bony anatomical situation. In addition, the distribution and axial position of the mini implants will be planned to achieve the best biomechanical distribution and the most parallel position between implants, perpendicular to the occlusal plane and path of insertion of the prosthesis. The primary outcome will be the accuracy of the implant position using the partially-guided protocol. Assessment of the accuracy of the methods will be based on the measure of the difference between the actual and the planned position of the mini implants, based on the measurement of (1) the global deviations at the coronal and apical regions of the mini implants, (2) the vertical deviation, and (3) the apical angle deviation. Overall impacts of treatment on oral health-related quality of life will be assessed using the Oral Health Impact Profile instrument for edentulous subjects (OHIP-EDENT). Additional outcomes will include implant survival and success rates, incidence of prosthodontic complications and peri-implant measurements.
