Filter by:Comparison of early and late loading of implants supporting full each prosthesis in upper jaw, using the Cresco prosthetic system on Straumann implants. The study hypothesis is that there is no difference between the bone loss (or gain) between the groups.
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 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.
The amendment to Clinical Protocol 86-D-0015, clinical study of Oral Endosseous Titanium Implants in Edentulous subjects, and patients with Ectodermal Dysplasia is to allow the Investigators to determine: (1) If placement of Endosseous Titanium Implants in pre-adolescent patients (age 7 to 10) will influence the growth and development of the craniomandibular complex. (2) The final position of the implant, the ability to fabricate prosthesis. (3) Body image, diet and perceived ease of chewing selected foods. Selection of patients for participation in the study will be based on the number of congenitally missing teeth associated with Ectodermal Dysplasia. At least 16 permanent teeth must be congenitally missing. A total of 30 patients will be included. A consent to participate in this study will be obtained from each patient: 18 & older - consent signed by patient 13-17 years - consent signed by parent, assent signed by patient 7-10 years - consent by parent, assent signed by child if capable of understanding or note on chart describing procedure used to obtain the child's assent to the study
