Filter by:This study was designed to assess peri-implant soft tissue health, volume and marginal stability at implants sites which presented small buccal bone dehiscences (<3mm evaluated in a vertical direction) at the time of insertion. Patients will be then randomly allocated to receive grafting with connective tissue graft or volume stable collagen matrix and evaluated at 3 months after surgery and at 12 months of follow up after crown placement.
A post-market, randomized-controlled, superiority clinical study to compare medium-term performance and safety of the Straumann PURE 2-piece Ceramic Implant with Straumann Bone Level Implant using a fully digital workflow.
The use of a passive robotic system allows the practitioner to widen the field of indications of flapless surgical access to the implant with an increased operative security and the possibility of an operative modification of the surgical protocol.
This study is set up within the framework of the European Union regulation 2017/745 on medical devices. Its objective is to confirm the performance and safety in the medium and long term of implant-prosthetic systems including Global D dental implants: In-Kone® UNIVERSAL, In-Kone® PRIMO, twinKon®, EVL® S, EVL® K and EVL® C.
Keratinized mucosa, which is composed of free gingiva and attached gingiva, is a barrier against bacterial invasion in oral cavity and provides good tissue sealing for periodontal environment. When the keratinized mucosa is insufficient, it is difficult to maintain the long-term stability of the implant, which is not conducive to the peri-implant health. It is generally believed that enough keratinized mucosa width is beneficial to reduce plaque accumulation and reduce the incidence rate of peri-implant diseases. In recent years, clinicians have gradually recognized that the thickness of keratinized mucosa plays an important role in maintaining the peri-implant health. Some researchers found that the thickness of mucosa is very important to maintain the aesthetic effect of implant restoration, and when the thickness of mucosa around the implant is less than 2mm, alveolar bone absorption will occur to maintain a stable biological width. A meta-analysis showed that when the thickness of the keratinized mucosa around the implant was greater than 2mm, the amount of marginal bone loss was significantly reduced (- 0.8mm, P < 0.0001). It is considered that autogenous soft tissue graft is the most reliable technology to augment keratinized mucosa. Subepithelial connective tissue graft (SCTG) is a mucogingival surgery that transplant autologous free connective tissue under the pedicled semi thick flap to augment keratinized mucosa. It can effectively increase the thickness of soft tissue, cover the exposed implant, and reconstruct the interdental papilla. It is the gold standard for peri-implant soft tissue agumentation. Keratinized mucosal thickening surgery may be done prior to the surgical phase, after the surgical phase, before loading, or even after loading. It is believed that keratinized mucosal thickening at the same time of implantation can effectively reduce the possibility of mucosal recession after implantation, reduce the amount of marginal bone absorption in the process of osseointegration, which is conducive to maintaining the long-term stability of the implant. For the sake of clear clinical vision and convenient operation, clinicians often choose to thicken the keratinized mucosa during the secondary operation, and also obtain good postoperative effect. However, after the completion of the final repair, the keratinized mucosa thickening surgery increases the difficulty of operation and the technical requirements for the operator. In clinical practice, it is rarely selected to perform keratinized mucosal thickening at this time. At present, the effectiveness of timing on the outcome of soft tissue augmentation is still debated, and, most importantly, a direct comparison between simultaneous and staged procedures remains underexplored. Therefore, this clinical trial is to prospectively compare the clinical efficacy of simultaneous versus delayed timing of soft tissue augmentation by SCTG placement around single implants, by evaluating the peri-implant marginal bone level change and soft tissue change, so as to provide reference for the formulation of clinical treatment plan and the selection of the best operation time.
Compare the survival rate of the implants placed using the ultrasonic technique and placed using conventional drilling, with an immediate load on the aesthetic zone.
H0: "Within the first year post-placement, four interforaminally placed, immediately loaded 2.4 mm narrow-diameter one-piece TiZr implants with miniaturized stud-type attachments show improved patient-reported outcome measures (PROMS) compared to two interforaminally placed, early loaded, TiZr two-piece implants with stud-type attachments to retain a mandibular overdenture."The specific aim is to compare both treatment alternatives to evaluate which one may be recommended for elderly edentulous patients.
Apply LSCI method for follow-up changes in regional blood flow after compression of the gingiva in order to compare the vascular reactivity of the attached gingiva at implant versus at tooth.
The Primary Objectives of the present study are : - To Evaluate the effect of platelet rich fibrin matrix (PRFM) and peripheral blood mesenchymal stem cells (PBMSCs) on implant stability. - To Compare the effect of platelet rich fibrin matrix (PRFM) alone to peripheral blood mesenchymal stem cells (PBMSCs) embedded in platelet rich fibrin matrix (PRFM) on implant stability.
To evaluate the clinical success, stability, radiographic bone level changes and peri-implants soft tissue parameter of the SLActive surface implant supporting single crowns restorations in early loading in the mandibular first molar region.
