Active clinical trials for "Mouth, Edentulous"

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.

This is a single-center, single-group, prospective clinical trial testing a partially-guided protocol for placement of mini implants overdentures in the edentulous maxilla. Eligible participants will be subjects with an edentulous maxilla, wearing a conventional complete denture. Participants will receive six mini implants (Straumann® Mini Implant System, Institut Straumann AG, Switzerland) for retention of a maxillary overdenture. The six mini implant protocol will be virtually planned for an even distribution of the implants bilaterally, with a minimum of 5 mm distance between contiguous implants. The available lengths of the mini implants are 10, 12, and 14 mm, and the appropriate length will be selected according to the bony anatomical situation. In addition, the distribution and axial position of the mini implants will be planned to achieve the best biomechanical distribution and the most parallel position between implants, perpendicular to the occlusal plane and path of insertion of the prosthesis. The primary outcome will be the accuracy of the implant position using the partially-guided protocol. Assessment of the accuracy of the methods will be based on the measure of the difference between the actual and the planned position of the mini implants, based on the measurement of (1) the global deviations at the coronal and apical regions of the mini implants, (2) the vertical deviation, and (3) the apical angle deviation. Overall impacts of treatment on oral health-related quality of life will be assessed using the Oral Health Impact Profile instrument for edentulous subjects (OHIP-EDENT). Additional outcomes will include implant survival and success rates, incidence of prosthodontic complications and peri-implant measurements.

The primary aim of this study was to compare the acoustic sound quality of edentulous patients rehabilitated with two-implant overdentures or the all-on-4 concept. The secondary aims were to evaluate the effect of implant and prosthetic success on acoustics.

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.

Partial or total edentulousness has a significant impact on quality of life both functionally and aesthetically. TBR® Tissue Level Z1 Implants allow the patient to prevent bone resorption and maintain facial tissue and musculature support. At the functional level, the patient who benefits from implant treatment regains normal masticatory function with all the benefits on the quality of life that this can bring him. Due to the osseointegration of the implant and the biocompatibility of the materials used, the implant treatment remains effective in the long term and makes it possible to maintain the aesthetics of the smile.

The principal aim of the study is to evaluate the prosthetic complications with CAD-CAM fabricated provisional prostheses and denture conversion prostheses after 3 months of function. Supported restorations are now a predictable treatment modality for the rehabilitation of complete and partially edentulous jaws.Immediate loading of the placed implants is performed for the rehabilitation of the edentulous arch to improve patients' function. This can be usually done by converting the existing denture base of the patient or by making a CAD- CAM milled provisional prosthesis integrating digital workflow. A laboratory fabricated denture base can be converted into a screw-retained provisional prosthesis post implant placement. This is known as conversion prosthesis. However, drawbacks of these prostheses include increased chairside time for the clinician leading to inconvenience for the patient and a potential for an error in prosthesis fabrication. With the introduction of CAD-CAM technology, it is now possible to fabricate a provisional restoration using digital workflows. This workflow would help the clinicians save a considerable amount of chairside time and obtain potentially stronger restorations better polished and without contamination of surgical field. Studies assessing the soft tissue response and patient-reported outcome measures between denture conversion and CAD- CAM fabricated provisionals are currently lacking in the literature.

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.

This study aims to compare the clinical performance of 4 mm short implants supporting cross-arch fixed reconstructions in the edentulous mandible either with a combination of two short implants as distal support and two implants of conventional length placed in the interforaminal region, or with a combination of four short implants as distal support and two interforaminal implants of conventional length.

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.
