Filter by:Our study looks into how the thickness of the gum tissue affects the health of the bone around dental implants over ten years. We include 59 people and divide them into three groups based on their gum tissue thickness. Some have naturally thin gums, some have thin gums that were made thicker with a special procedure, and some already had thick gums. We try to find out if having thicker gums, whether naturally or through enhancement, can help keep the bone around dental implants healthy in the long run.
The present randomized controlled trial aims to assess the influence of a new prosthodontics device (Gingival Former Abutment -GFA) on peri-implant bone loss and soft tissue changes and health after subcrestal oral implant placement. The participants will be divided in two groups and receive either crestal implant placement and traditional healing abutment or subcrestal implant placement and GFA. Clinical and radiographic examination will be performed at implant placement surgery, prosthetic load, 6 and 12 months follow-up.
The purpose of the study is to evaluate the use of a magnetodynamic instrument (Magnetic Mallet®, Metaergonomica, Turbigo, Italy) to perform a horizontal bone expansion in edentulous sites that need to be rehabilitated with a dental implant.
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.
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.
24 patients with missing premolar teeth and healed sockets will be recruited. They will be randomized into two groups to supplied with tissue-level (n=12) or bone-level (n=12) 10-mm long 4-mm wide zirconia implants. Primary and secondary stabilities will be measured with International Stability Quotient (ISQ) device. After 3 months, ceramic crowns will be supplied. Implant survival rates and parameters in relation to periimplant soft-tissues and bone health and anatomy will be recorded and evaluated after 1, 3 and 5 years.
The goal of the present randomized clinical trial is to assess the long-term osseous and peri-implant soft tissue changes as well as the success rate of short implants (6 mm) with a converging collar with micro threads or a diverging polished collar placed in the esthetic zone of the maxilla on partially edentulous patients. The main questions it aims to answer are: - what are the long-term bone and soft tissue changes around implants with a converging collar with micro threads compared to a diverging polished collar placed in the esthetic zone of the maxilla? - What is the success rate of implants with a converging collar with micro threads compared to a diverging polished collar placed in the esthetic zone of the maxilla? Dental implants with a converging collar with micro threads or a diverging polished collar will be placed in the esthetic zone of the maxilla of the included participants and the measurements regarding the bone and soft tissue level will be compared.
This study is designed as a Prospective Randomized Clinical Trail, Evaluate the effect of osseodensification technique on primary stability in comparison to the conventional drilling technique in immediate single fresh extraction sockets.
The purpose of this study was to assess the effect of Bio-Hpp versus Co-Cr custom abutments in fixed-detachable implant-supported mandibular partial dentures clinically and radiographically in Class I Kennedy classification (split-mouth study)
