9 Clinical Trials for Various Conditions
Study to assess the performance of six short implants (ANKYLOS C/X 6.6 mm) in the edentulous maxilla supporting fixed full-arch bridges after 5 years in function.
A 510k approved dental device for subjects requiring single or multiple tooth replacement with implants where immediate restoration/loading is preferred.
The purpose of the study is to evaluate ASTRA TECH Implant System, OsseoSpeed™ implants, in patients with totally edentulous upper jaws and poor bone quality and quantity, when provisional artificial teeth are attached within 24 hours. The primary objective is to investigate implant survival rate.
Sinus augmentation, also referred to as a sinus lift or a sinus graft, is an oral surgery procedure where bone is added to the upper jaw near the molars. The goal of the surgery is to add enough bone material onto the upper jaw to support the placement of a dental implant. The augmentation and the dental implant placement will be done at the same time to avoid the need for two surgeries. This is standard of care. The purpose of this study is to compare any problems and patient comfort levels following surgery. Subjects will be randomly placed into one of two groups: the internal lift group or the external lift group. Both types of surgery are routinely done at our clinic. Usually the type of procedure (internal or external) is based on the dentist's preference. Investigators are doing this study to compare them to each other to see if one is more comfortable for the subject than the other or if they are equal. It is predicted that the two techniques may differ when it comes to complications during the procedure, patient discomfort following the procedure and patient complications in the weeks and months after the procedure. This last comparison has not yet been studied, and surgeons often choose the technique that they prefer from their own experiences. With this research study researchers hope to gain valuable information that will help surgeons' decisions in the future. * Investigators hypothesize that external sinus augmentation with simultaneous implant placement (external technique) will have a higher rate of Schneiderian membrane perforation than the internal sinus augmentation with simultaneous implant placement (internal technique). * Investigators hypothesize that the internal technique is associated with more discomfort for the subject compared with the external technique. * Investigators hypothesize that the external technique will result in more severe pain/bleeding/swelling than the internal technique. * Investigators hypothesize that the internal technique has a higher incidence of complications that occur between three weeks and three months postoperatively compared with the external technique. * Investigators hypothesize that the external technique has a higher amount of analgesics taken postoperatively compared with the internal technique
The purpose of the study is to evaluate Astra Tech Dental Implant System, Fixture Osseospeed™, in patients with tooth loss in the posterior maxilla in an early loading protocol. Primary objectives are implant stability, marginal bone adaptation and survival rate.
The purpose of this study is To demonstrate that there is no difference in change in bone level around P.004 implants between 1st stage surgery and 6 months post surgery when transmucosal implant placement is compared to submerged implant placement
The purpose of this study is primarily to evaluate implant survival rate of Astra Tech Fixture ST placed in the posterior maxilla. A one-stage surgical protocol will be used and the implants will be loaded four weeks after implant installation (early loading). Marginal bone levels, plaque and status of the periimplant mucosa will also be evaluated. The subjects will be followed for three years.
The purpose of this study is to evaluate survival for ASTRA TECH Implant System, OsseoSpeed™ implants following immediate loading in extraction sockets versus immediate loading in healed ridges. Patients in need of single standing implants replacing teeth in the maxilla within zone 15-25 will be included and followed for 5 years. Primary objective is implant survival rate at 12 months.
This study will identify and enroll patients already scheduled to receive guided maxillary implant placement with palateless overdenture. Standard clinical practice will be followed for this multi-stage process. The study purpose is to evaluate the degree of satisfaction during the standard progression in order to determine at which post edentulous stage patients achieve maximum satisfaction using the Oral Health Impact Profile 49 (OHIP 49).
