Filter by:The goal of this split-mouth randomized clinical trial study was to investigate the effect of using a laser on pain and discomfort following flapless dental implant surgery. It was hypothesized that laser did not have any impact on post-op pain. Therefore, the study aimed to compare pain and discomfort following flapless dental implant surgeries with or without a laser.
This clinical trial aims to observe if there are differences in bacterial micro-filtration on interfaces and to evaluate if there are differences in the occurrence of peri-implant diseases and bone loss in fixed partial monolithic zirconia CAD/CAM implantsupported prostheses with and without abutment in patients at the Advanced Implant Prosthetics Clinic of the Complutense University of Madrid, of both sexes, over 18 years of age, whose treatment plan is based on the replacement of dental pieces with two fixed partial dentures on implants, in such a way that the study will be performed "split mouth" rehabilitating one of them with zirconia bridges on attachments with connection and others with Zirconia bridges with flat attachments or without connection. The main question it aims to answer is whether the not use of abutment influence bacterial micro-leakage and the development of peri-implant diseases and bone loss at that level in fixed partial monolithic zirconia CAD/CAM prothesis. Participants will: - Receive two fixed partial monolithic zirconia CAD/CAM prothesis, one will be attached to an abutment (control group) and the other not (test group) - Subsequently, control appointments of the fixed implant supported prosthesis treatment will be performed (1, 3,6, 12 and 24 months) and radiographies will be made with the parallelizing device attached by the silicone key. Researchers will compare fixed partial monolithic zirconia CAD/CAM implant-supported prostheses with and without abutment to see: - Differences in bacterial micro-leakage on interfaces. - Occurrence of peri-implant diseases and bone loss
A total of 34 participants, who require replacement of an anterior or posterior single tooth with dental implant, will be randomly allocated to two equal sized groups. In the control group, the osteotomy site preparation will be prepared by using conventional surgical drills, while the test group site preparation will involve the use of Densah™ Burs (Versah Co., LLC., USA) as per the osseodensification protocol. In addition to evaluating implant stability, the trial will also report on implant and patient outcomes at various time points.
In dental implant restoration, available literature demonstrates the advantage of using tall abutments, with a change of diameter with respect to the implant and a conical internal connection in the abutment-implant gap. However, for multiple restorations, the abutment-prosthesis connection has not been studied in detail. The "multi-unit" systems, both standard and brand specific, have either a flat or butt joint or an cone. In any case, both are external connection systems. Recently, an internal-type abutment-prosthesis connection system has been developed. Although it is proving its usefulness in single restorations, its use in multiple restorations compared to traditional systems has not been studied. Therefore, taking into account all of the above, the present study has the overall objective of analyzing marginal bone loss (MBL) and adaptation of soft tissues by comparing a multiple prosthesis system of the "external, flat" type versus an external system of the "internal, conical" type.
Dental implants may suffer from bone loss around them, particularly at the upper portion where the prosthesis starts. The connection between both parts of the tooth restoration is key for avoiding micromovement during chewing, bacterial contamination and initiation of bone loss. Thus, investigating factors related to this bone loss in different types of implant-prosthetic connections is key for promoting better use of available therapeutics devices. In this study, we will study marginal bone levels over time as well as bacterial contamination and inflammatory markers in the peri-implant sulcus around implants with connical connection and compare them with those obtained when using implants with internal hexagonal connection. The hypothesis is that bone loss will be higher in implants with hexagonal connection associated with a pathological microbiome in the sulcus that induces a higher inflammatory response.
The purpose of this study is to evaluate the clinical outcome of implant survival of the PrimeTaper EV implant in single tooth restorations 1 year after permanent restoration.
The aim of is to compare the survival rate and technical outcomes of cantilever implant-supported fixed denture prosthetics (cFDPs) made either out of monolithic zirconia bonded to a titanium base in a digital workflow, or porcelain fused-to metal using a gold abutment in a conventional workflow. In addition, biological outcomes, wear patterns, PROMs and time efficiency will be recorded. The null hypothesis is: the reconstruction type does not influence the survival rate and technical outcomes of 2-unit implant-supported cFDP.
Patients where placement of a single implant will be treated by senior dental students under close supervision of experienced spcialists. All implant treeatments will be categorized as "straight forward"according to the SAC classification. The patients will be randomized to have the implants placed using a fully guided or a convetionally guided protocol. Outcome parameters include accuracy of implant placement compared to an ideal implant position, patient- and student-reported outcome.
The Neodent® Zirconia Implant is designed for the treatment of oral endosteal implantation for the functional and aesthetic rehabilitation, allowing for treatment of patients with different bone qualities. The objective of the study is to assess the success and survival rates of implantable devices of the Zirconia System, in order to confirm the long-term safety and clinical performance of implants and abutments of the Zirconia System in daily dental practice setting. Devices will be used according to standard routine in daily practice, according to manufacturer indications in the IFU. Patients will be followed for 36 months after implant placement.
Placement of implants in diabetic patients is associated with higher risk of implant failure and peri-implant marginal bone loss due to an increased susceptibility to infections, impaired wound healing and associated microvascular complications. However, diabetic patients do not encounter a higher implant failure rate compared with non-diabetic patients, if the plasma glucose levels are normal. Prosthetic rehabilitation of the posterior maxilla with implants is frequently compromised due to atrophy of the alveolar process and pneumatisation of the maxillary sinus. Maxillary sinus floor augmentation (MSFA) with autogenous bone graft is generally considered the preferred grafting material due to its osteoinductive, osteogenic, and osteoconductive properties. However, harvesting of autogenous bone graft is associated with risk of donor site morbidity and unpredictable resorption of the graft. Thus, bone substitutes, blood coagulum and platelet rich fibrin are used increasingly to simplify the surgical procedure. Fabrication of advanced platelet rich fibrin (APRF) from blood samples possess significant potential for bone regeneration without the use of additional autogenous bone grafts or bone substitutes. Consequently, use of APRF in conjunction with MSFA will avoid bone harvesting and simplify the surgical procedure. The objective is to test the H0-hypothesis of no difference in implant treatment outcome after MSFA with particulated autogenous bone graft compared with APRF. Forty consecutively insulin-dependent diabetes patients with missing posterior maxillary tooth/teeth will be allocated to implant placement and MSFA with particulated autogenous bone graft from the zygomatic buttress or APRF. Blood samples will be obtained preoperatively and postoperatively. Clinical and radiographical evaluation using periapical radiographs and CBCT will be performed preoperatively, immediate postoperatively, before abutment connection, after prosthetic rehabilitation, one year, three years and five years after loading to assess the implant treatment outcome and the volumetric changes of the augmented area. Outcome measures will include survival of suprastructures and implants, volumetric stability of the augmented area, peri-implant marginal bone level, immunological analyses of blood samples, oral health related quality of life, and complications related to the two treatment modalities.
