Filter by:The Narrow GM Implants were designed for oral functional rehabilitation using dental implants, allowing for treatment of patients with different bone qualities in the region of lateral incisors in the maxilla or the region of lateral and central incisors in the mandible. The objective of the study is to confirm the long-term safety and clinical performance of implants and abutments of the Narrow GM System in a daily dental practice setting, by means of a prospective collection of clinical data in an observational study using these devices. Devices will be used according to standard routine in daily practice, according to all indications as specified by the manufacturer in the instructions for use (IFU). 55 patients (needed to obtain a sample size of 55 implants) will be followed for 36 months and monitored for Adverse Events by the Investigators until the last protocol-related procedure of a patient is completed.
BMAC is used on 3D printed PCL scaffold for horizontal ridge augmentation in aesthetic zone , BMAC contains MSCs which can differentiate in osteogenic medium into osteoblasts which can lay down bone
Anthogyr Axiom Tissue-Level implants and corresponding Multi-Unit abutments recently enriched the available product range for dental surgeons. This Post-Market Clinical Follow-Up study aims at confirming the safety and performance of these products. The comparison with similar Anthogyr Axiom Bone-level implants will provide additional information on the effect of platform-switching in bone level maintenance for single and two-piece design at the implant level.
The bone grafting materials currently used in dentistry are autografts, allografts, xenografts, and alloplastic grafts. Among these different types of bone graft materials, autografts are considered to have the most predictable results due to their properties of osteogenesis, osteoinduction, and osteoconduction. However, bone autografts are rarely used due to the high morbidity associated with harvesting the bone graft from the patient with a second surgical site. Because of the increased risk to the patient with autogenous bone grafts, the current standard of care is an allograft, which is a bone graft harvested from cadaver sources such as Freeze-Dried Bone Allograft (FDBA). While allografts can only possess the qualities of osteoinduction and osteoconduction, they also have dramatically less morbidity due to the lack of a second surgical site. Our null hypothesis states that: Experimental groups (mineralized, and partially demineralized dentin grafts) do not show positive changes in implant stability, survival, failure rate, probing pocket depth, and interproximal crestal bone level changes when compared to FDBA Our alternative hypothesis states that: Experimental groups (mineralized, and partially demineralized dentin grafts) show similar or better results in terms of implant stability, survival, failure rate, probing pocket depth, and interproximal crestal bone level changes when compared to FDBA.
This study is a randomized clinical trial comparing the conventional method of recording occlusal vertical dimension using Willis gauge from the base of the nose to the base of the chin with the other method using vernier caliper for the length of the index finger to access the satisfaction level of edentulous patients acquiring complete dentures.
Comparison of Piezoelectric split-crest technique versus expansion using Hand Driven Ridge Expanders in treatment of Maxillary Narrow Ridges
Total edentulism is a profound physical, psychic and social handicap, which affects 5 million people in France. The most frequent complaint of edentulous patients rehabilitated by conventional Complete Removable Prostheses (CRP) is the reduction of masticatory efficiency. This alteration has medical repercussions and a negative psychological and social impact. Our study aims to evaluate the impact of an innovative protocol on the quality of masticatory function, prosthetic treatment and, in fact, on the quality of life of the totally edentulous patient. This protocol combines the Digital Denture system with the transcutaneous electrical neurostimulation system (TENS®), in order to improve the balance of the dento-dental contacts of CRP. This new protocol is called DDTENS. The first objective of the study is to compare the activity and balance of the masticatory muscles at 1 month (T1) of wearing the prostheses, between an experimental group benefiting from a CRP by the DDTENS protocol and 2 reference groups ( the first benefiting from a CRP by the conventional procedure and the second by the Digital Denture procedure) in bimaxillary total edentulous patients The secondary objectives are: - to compare the number of sessions required to obtain a finalized bimaxillary total removable prosthesis between the 3 groups. - to compare the quality of life of patients with their CRP between the 3 groups, at 1 month and 4 months of wearing the prostheses. - to compare the activity and balance of the masticatory muscles when the prostheses were put in the mouth (T0) and at 4 months (T4) of wearing the prostheses The study design is a randomised open-label controlled pilot study with blinded reviewer assessment comparing 3 parallel groups: - Experimental group: 10 bimaxillary edentulous patients rehabilitated by CRP using the DDTENS protocol. - Control group 1: 10 edentulous bimaxillary patients rehabilitated by CRP according to the conventional method (gold standard technique). - Control group 2: 10 edentulous bimaxillary patients rehabilitated by CRP using the Digital Denture procedure. The expected benefits for patients in the DDTENS experimental group are the optimization of occlusal balance, the optimization of the time of integration of the prosthesis in the mouth, the time saving in the prosthetic treatment of the edentulous patient and the improvement of eating behaviours and quality of life of edentulous patients which would delay the entry of our patients into the sphere of dependence. These results would allow the validation of a new rehabilitation protocol for the edentulous patient, leading to a modification of clinical practices.
The purpose of this study is to evaluate the soft tissue clinical results in patients that received, or not, a soft tissue augmentation around dental implant inserted immediately after the extraction.
comparing retention and patient satisfaction of implant-supported mandibular overdentures retained by conventional nylon clip and metal housings for ball attachments versus PEEK clip and housings
Today, tooth- or implant-supported single crowns and short-span fixed partial dentures can be fabricated on the basis of an intraoral scan, but the scanning accuracy decreases with increasing length of the jaw section to be captured. An accurate scan is also made more difficult by edentulous jaw sections, as these provide the scanner with few landmarks for proper three-dimensional image composition. With respect to both edentulous and edentulous patients with dental implants, the currently available literature does not provide a firm basis for deciding whether such patients can already be scanned with sufficient accuracy. It is considered problematic in this context that the findings on digital impression accuracy, regardless of whether teeth or implants have been scanned, are based almost exclusively on the results of in vitro studies. Conclusions about the accuracy of intraoral scanners under clinical conditions with moving patients and limited accessibility to the structures to be imaged, especially in the presence of blood, saliva or sulcus fluid, are extremely limited based on these data. Therefore, the aim of this study is to determine the clinical scanning accuracy of two current intraoral scanning systems for the three-dimensional acquisition of the position of two interforaminal dental implants in the edentulous mandible. The influence of artificial landmarks to achieve increased scan accuracy will also be tested.
