Filter by:The purpose of this study is to assess the change of crestal bone level at the Titanium Zirconium (TiZr) compared to Titanium (grade IV) implant between surgery and 6, 12, 24, and 36 month post surgery.
The objective of the study is to test the efficacy on bone formation of Straumann Bone Ceramic as a grafting material applied in buccal bone dehiscences on simultaneously placed oral implants.
The primary objective of the study is to evaluate the long-term survival rate of individual implants and prostheses when treating edentulous upper jaws of poor bone quality with Fixture MicroThread™ (Micro-Macro). Clinical study recruitment was stopped in year 2000 due to a decision to modify the product under study. This was a result of feedback regarding the subjective feeling during the installation procedure. There were no safety concerns w/r to the study products. Patients already included and treated in the study were monitored for the full duration of the study in accordance with the clinical study protocol.
The primary objective of the study is to evaluate the long-term survival rate of implants and prostheses when treating totally edentulous upper jaws with Fixture MicroThread (Micro-Macro) using a one-stage surgical procedure. Clinical study recruitment was stopped in year 2000 due to a decision to modify the product under study. This was a result of feedback regarding the subjective feeling during the installation procedure. There were no safety concerns w/r to the study products. Patients already included and treated in the study were monitored for the full duration of the study in accordance with the clinical study protocol.
The purpose of the study is to evaluate Astra Tech Dental Implant System, Fixture Osseospeed™, in patients with tooth loss in the posterior mandible in an early loading protocol. Primary objectives are implant stability, marginal bone adaptation and survival rate.
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 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.
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.
Fifteen (15) patients completely edentulous in the maxilla will be treated with 8 dental implants. The total treatment will be done in 2 stages to allow, within the same group, a study of two different approaches. Miniscrews that can be functionally loaded will be provided by 3i with the design and surface textures as wanted by the study sponsor.
This is a randomized open label trial that evaluates the efficacy of an autologous platelet concentrate (APC) in pre-implantation reconstruction of maxilla. The sinus occlusion will be performed under general anaesthetic. On one side by the usual technique with hipbone transplant, the other side will be restored with APC mixed with autologous bone tissue removed from the surgery site. The side selection will be determined by the randomization.
