Filter by:The objective of this study is to evaluate the survival of narrow dental implants (≤ 3,5 mm) in multiple fixed prostheses in comparison with standard diameter dental implants (≥ 3,75 mm) after 5 years of follow-up. The hypothesis of the study is that narrow dental implants under the evaluated conditions, have the same survival rate and clinical performance than the standard diameter implants.
Materials and methods: fourteen patients were selected according to the inclusion criteria, the participants were stratified equally into two groups, patients were assigned to receive either monoplane or lingualized occlusal schemes to their overdentures. For each patient placement of two mini-implants in the mandible at the canine region was done, bar joint attachment was used to splint the mini implants. Each implant was 2.5 mm in diameter and 10 mm in length. T-scan occlusal load analysis records were done in centric occlusion , the records was used to analyze the biting force of the denture as a Full Closure Force Movie recording, then Time vs. Force Graph of that Force Movie is accomplished. T-scan records were taken three times for each patient in the two groups ,Immediately after loading ,three months and six months of loading.
Twelve participants with edentulous alveolar crests in the distal portion of the arches will be included in the study. At least two implant sites will be identified in each patient and will be sub-prepared with drills or sonic instruments. One site will be used as a test and one as a control where experimental mini-implants will be installed. Reconstructive surgical procedures will be applied at the biopsy sites.
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
A multicenter prospective observational study in which aim is to illustrate the clinical outcome of dental implants "Kontact N"; and the effects of its nanostructured surface on the osseointegration and secondary stability without increasing the rate of peri-implantitis. All the enrolled patients will be eligible for one or multiple implant-supported fixed restoration(s) according to the routine clinical practice and the manufacturer's instruction for use.
20 recruited patients indicated for immediate implant placement in mandibular molar patients are divided into 2 groups each group contain 15 patients, one group assigned for placement of bovine bone after molar extraction and immediate implant placement, while the other group we use Platelet-rich fibrin as space filling material.
As Regenerative Medicine is the next level in medicinal sciences, the use of mesenchymal cells have become prevalent, Similarly now stem cells are being used in dental research as well in various clinical applications.This study aims to evaluate the overall effect of osseointegration by use of Allogenic Mesenchymal Stem cells while placing dental implants.Healthy subjects will be chosen and dental implants placed bilaterally one with standard surgical protocol and other with the use of Allogenic Mesenchymal Stem cells.The implant stability is checked using Resonance frequency analysis(RFA).The RFA values are statistically evaluated at various intervals and observations will be analysed on both test and control side.
The present retrospective study aims at assessing the clinical effects of a novel implant site development (Extraction site development - XSD) technique after tooth extraction compared with extraction alone in patients requiring dental implant placement following healing of extraction sockets.
1. Hypothesis/Specific aims The aim of the present study proposal is to validate an implant treatment concept in the edentulous upper maxilla using four implants-supported locators abutments to retain removable prosthesis. Specific aims: - The primary objective of the study is to evaluate the implant and prosthodontics success rates of the proposed implant treatment approach after a follow-up period of 1, 3 and 5 years as well as the biological and prosthodontics complications. - The secondary objective is to assess the evolution of patient centered outcomes with the suggested treatment in the maxilla. Oral health-related quality of life (OHRQoL) and patients' satisfaction relating to their prostheses will be considered. - The third objective will be to compare the implant, prosthodontics and patient-centered outcomes according to the implant distribution; 4 anterior to maxillary sinus (ANT) versus 2 anterior implants and 2 implants in the maxillary tuberosity (POST). Hypothesis: - Implant survival rate using this treatment concept is similar to restoration with implant-supported fixed prosthesis, based on published data. No difference of implant survival rates is found between ANT and POST implant distribution. - Prosthodontics survival rate using the following treatment concept is similar to the ones found with a bar, based on published data. The ANT implant distribution causes fewer prosthodontics complications compared to the POST implant distribution. - There is a significant improvement in OHRQoL and patient satisfaction compared to the baseline OHRQoL observed with a conventional removable denture. The levels of improvement OHRQoL and patient satisfaction are similar for ANT and POST implant distributions.
This is a prospective, randomized, controlled, parallel group Phase 1/2 assessment of the safety of GINTUIT versus Bio-Gide in subjects who have a posterior tooth requiring extraction. The incidence and severity of adverse events will be summarized by group (GINTUIT and Bio-Gide).
