View clinical trials related to Edentulous Alveolar Ridge.
Filter by:It is a randomized control clinical trial in which maxillary and mandibular dentures will be constructed, two implants will be inserted in the inter foraminal region in the edentulous mandible and immediate loading will be done. We will be comparing peri-implant marginal bone loss of two immediately loaded implants retaining mandibular overdentures with ball attachment versus intra oral welding titanium bar. Patient satisfaction will be assessed using oral health related quality of life.
- Background There is a growing interest in restoring function in the posterior maxilla and mandible with dental implants. Next to this, these implants must be restored with crowns which are subject to minimal complications. Companies have introduced the option of screw-retaining and zirconia as crown material. The combination of posterior implants and screw-retained zirconia crowns are widely used, but prospective research on clinical performance and patient centered outcomes are scarce. Even more, 5-years data are lacking. - Main research question To evaluate the clinical performance of Astra Tech Implants EV and Atlantis CustomBase Abutments with full-contour zirconia Atlantis Crowns in the posterior maxilla and mandible. The primary objective of the study is marginal bone level changes by radiological assessments at 5-years follow-up. Secondary objectives are implant and restoration survival, condition of peri- implant mucosa and patients' satisfaction. - Design (including population, confounders/outcomes) The study design is an observational study of a group of patients which were treated 5 years ago with a dental implant and a screw-retained implant-supported zirconia restoration because of a missing tooth in the posterior region. Outcomes: primary outcome is the change in marginal peri-implant bone level 5 years after placing the definitive restoration. Secondary outcome measures will be implant and restoration survival, peri-implant mucosa health and patients' satisfaction using a questionnaire.
Isolated sinus pneumatization after single tooth extraction indicate sinus lifting for proper implant placement. The conventional way of using osteotomes to elevate the sinus is annoying to patient and also does not give the needed amount of bone around the implant. Introducing new intervention of Densah Burs helps increase bone gain around implant and decrease the patient discomfort.
The purpose of the study is to compare soft tissue volume changes in terms of volume gain and stability around dental implants and PROMS in cases where a sub-epithelial connective tissue graft (SCTG) from the palate, Porcine collagen matrix (CM) or Porcine Acellular dermal matrix (PADM) is used after 3 and 15 months after implant placement.
- Patients were randomly divided in to two groups by using computerized software ; the first group received flat magnetic attachment design while the second group received dome magnetic attachment design.which the inclusion criteria is completely edentulous patient ,Age range from 40 to 70 year old ,skeletal class 1, both sexes - Implant stability will be measured for both groups using smart peg /osstell at the day of implant installation and after 2,4,8,12 weeks. - Patient satisfaction measure in 2 weak and after 12 weak by Denture satisfaction questionnaire
On of the main fixed prosthetic options of completely edentulous patients is the screw-retained implant supported prosthesis which was constructed on transmucosal abutments with its encountered problems such as: hardness to make it passively seated with multiple screw fracture and loosening problems and multiple encountered veneer material fracture and so there effect on patient satisfaction with multiple maintenance recalls.so, the investigators want to try a new technique of fabrication which was proposed for reducing the problems of lack of passivity which is the intraoral luting cement technique on titanium bases with reduced screw number but, with luting cement problems as de-cementation and cement biological effects on soft tissues and bone and there effect on number of patient recall visits and maintenance and so there effect on patient satisfaction
