View clinical trials related to Jaw, Edentulous.
Filter by:The study involves 20 patients who require implant treatment for the edentulous lower jaw, following specific inclusion and exclusion criteria. Patients are drawn from the regular pool of those seeking implant therapy, with no additional recruitment efforts. This study compares the effects of loaded and non-loaded dental implants. Preoperative assessments include medical histories, clinical, and radiographic examinations of the jaw. Participants are thoroughly informed about the study procedures and consent to participate through signed agreements. They undergo preoperative diagnostics, including panoramic X-rays to evaluate mandibular bone height, and complete the OHIP-G 14 questionnaire to establish a baseline for their oral health-related quality of life. The implant placement involves standard outpatient surgical procedures under local anesthesia. The implants used are CE-certified and are placed in predetermined positions in the edentulous region. During the surgery intraoral scans and conventional impressions are performed. Post-operative care includes oral rinses, and radiographic assessments, with follow-up visits scheduled for suture removal and further assessments using the visual analog scale for pain and swelling. The healing phase spans four months, during which patients' comfort and oral health are monitored through clinical examinations and additional questionnaires. Follow-up after 4 months includes re-entry surgery and further radiographic evaluations and intraoral scans to assess the bone's response around the implants. Throughout the study, adverse events and patient satisfaction are continuously documented. In the later stages, regular follow-up visits for up to 24 months post-surgery to monitor implant stability and health through clinical and radiographic check-ups are performed. This study aims to document implant survival rates, peri-implant bone regeneration, assess biological and technical complications, and evaluate patient satisfaction and quality of life throughout the implant process, providing valuable data for future dental implant protocols.
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.
Objectives: Passive fit of screw retained frameworks is essential to avoid biological and mechanical failures in addition to transmission of unfavourable stresses to the bone-implant interface. However, Several factors contribute to the passive fit of screw retained prosthesis such as relative parallelism between the implants, implant number, impression material, impression technique and method of prothesis fabrication. The current study aims to evaluate the accuracy of three different impression techniques on the fit of screw retained bar splinting two inter-foraminal implants. Methods: The study presents evaluation of the passive fit of screw retained bar fabricated with three different impression techniques.
This clinical study, funded by the company Dentsply Sirona, is being carried out to see if the newly developed tooth implant "OmniTaper EV" is safe, effective and functions as intended when replacing a lost or removed tooth. The OmniTaper EV implant is a further development of existing dental implants. It is made of titanium, a metal that is well tolerated by the human body, which has been successfully used in dental implants for more than 40 years. All components used in this study are available on the market, are CE-marked and will be used according to intended use and approved instructions. The study involves at 11 planned clinic visits including follow-up visits 6 months and annually until 5 years after installation of the permanent crown. after over a period of about five and a half years. The treatment method and healing period may vary depending on the individual case and treatment plan and additional visits may therefore need to be scheduled. The visits and procedures are the same as standard of care and no procedures will be done just for purpose of research. The study aims to recruit about 137 men and women from six clinics across Europe (Germany, UK and Switzerland) and participants can only receive one study implant each. Participation is entirely voluntary and participants can choose to withdraw from the study at any time, without giving a reason. The decision to decline or withdraw participation will not affect participants future treatment or care
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.
Nuvo Tapered IF (internal hexagonal connection) and CF (conical connextion) Implants were designed for the the oral functional rehabilitation using dental implants, allowing for treatment of patients with different bone qualities. The aim of the study is to confirm the long-term safety and clinical performance of implants and abutments of Nuvo IF and CF in daily dental practice setting, by means of prospective collection of clinical data in randomized clinical trial using these devices. Devices will be used , according to manufacturer indications in the IFU. Patients will be followed for 36 months after implant loading.
This will be a prospective, observational study where all implants will be placed in either the maxilla or mandible and loaded immediately (within 48 hours), early (within 6-8 weeks) or delayed (> 8 weeks) with a provisional or definitive prosthesis. The implants will be evaluated yearly for 2 years.
the purpose of this study is to clarify the rationale for the choice of the upper or lower jaw for positioning the occlusal splint
Main aim of this study was to assess survival rates of short implants with a length of 4 mm in the edentulous mandible after 1, 3, and 5 years.
