Filter by:The aim of the study is to determine whether regular use of the antibacterial, photodynamic, CE-marked Lumoral device reduces the risk of osteolysis after dental implant surgery. The study also aims to find out whether Lumoral treatment can replace the use of chlorhexidine. Subjects will be randomized into two groups (20 + 20 subjects) and all will be given individual guidance on maintaining good oral hygiene. The participants in the study group will also be given Lumoral appliances with instructions for use at home. The Lumoral device has been shown in previous studies to be safe to use and effective in eliminating harmful oral bacteria.
Numerous materials are nowadays used in the fabrication of healing abutments to be used for dental implants. soft tissue response to different healing abutment materials is still to be unraveled. the Aim of this study is to compare the soft tissue response to titanium stock healing abutments to customized composite healing abutments through assessing the level of matrix metalloproteinase-8 in the peri-implant crevicular fluid
The purpose of the study is to evaluate in novice surgeons the accuracy of the X-Guide® navigation system (X-Guide®, X-Nav Technologies®, Pennsylvania, USA) in implant placement compared to freehand implant placement.
The study suggests that if the investigators used customized healing abutments synthesized from PEEK may have a favorable effect on peri-implant soft tissues regarding decreased plaque accumulation and healing stimulation compared to the customized conventional titanium healing abutments.
The goal of this [clinical trial] is to [To evaluate both the clinical and radiographical outcome on osteointegration and peri-implant bone density when using ultra wide diameter implant placed immediately in molar extraction socket]
The objective of study is to evaluate the influence of the use of Platelet Rich Fibrin (PRF) from the patient's produced by a new horizontal centrifugation protocol associated with particulate xenogenous bone graft in the rehabilitation of atrophic maxillary sinus for early osseointegrated implants plancement. In a split-mouth model, twelve patients in need of rehabilitation with at least two bilateral implants in the regions of atrophic maxillary sinus will simultaneously undergo bone reconstruction using deproteinized particulate xenogenous bone (Bio-Oss Small®; Geistlich AG, Wolhusen , Switzerland). Randomly, one of the surgical sites of each patient will be reconstructed using the associated technique of solid PRF + Liquid PRF with the xenogen material, where at the end of the grafting procedure, both sites will be protected by a collagen membrane (Bio-Gide® Compressed; Geistlich AG, Wolhusen, Switzerland) positioned over the surgical access of the maxillary sinus. During the research, cone-beam computed tomography scans will be performed preoperatively, immediately after surgical procedure, 3 months after maxillary sinus reconstruction, after immediate implants placement and 12 months after functional load of the implants for comparative volume measurement of tissue gain and the maintenance of the grafted tissue. During the implant surgery, bilateral biopsies will be collected after 4 months of the regenerative surgical procedure during the early dental implants surgery by virtually guided surgery. The stability of the implants will be measured by means of resonance frequency analysis (ISQ) after the immediate postoperative period and 6 postoperative months as the clinical success rates of the implants after 12 months with functional load. The tissue samples will be used for histological, histomorphometric, immunohistochemistry and microtomographic analysis. All data obtained will be statistically analyzed.
The aim is to compare the microbiome composition on the first month of healing and 2 years after rehabilitation in two different implant surfaces (SLA® vs SLActive®). Subjects in need of two or more dental implants (canine to molars) in two different quadrants will be included so that, one study test (SLActive®) and one study control (SLA®) implant will be placed in different quadrants in healed extraction sites. Gingival crevicular fluid (GCF) samples will be taken for microbiome analysis at different time points. Samples will be processed using high throughput sequencing technologies (Illumina® MiSeq) and the raw sequencing reads will be processed with the Quantitative Insights Into Microbial Ecology (QIIME2) pipeline. DADA2 will be used for quality trimming and inferring amplicon sequence variants (ASVs). Taxonomy will be assigned to ASVs using the Naive Bayesian Classifier integrated in QIIME2 plugins and the eHOMD RefSeq database. Alpha-diversity and Beta diversity will be calculated and measured. Differences in bacterial abundance will be analyzed using linear models for differential abundance analysis (LinDA). This is the long-term follow-up of the randomized clinical trial entitled "Randomized controlled study to evaluate the clinical behavior of dental implants with SLActive® surface vs. SLA® surface" Promoter Code: CR 2017-05, Internal Code: 18/580-R_P, Promoter: Institute Straumann AG. In this new protocol, the participants included in the clinical trial at the Complutense University of Madrid will be selected, who will undergo a new follow-up visit at 2 years, to measure the clinical, radiographic and microbiological situation. periodontal treatment without any additional intervention. In addition, it is intended to analyze the microbiome of the samples of gingival crevicular fluid that we have frozen from the patients of the UCM, as well as of the samples that are taken after two years. All these changes are promoted by our ETEP (Etiology and Therapeutics of Periodontal and Peri-implant Diseases) research group, independently of the original sponsor of the study.
The aim of this study was to characterize the host-related response of peri-implant soft tissue induced by 3 different materials: titanium, resin and PEEK (polyetheretherketone) on man. The primary endpoint is to asses the histological data available: Histological analyses are carried out with immunohistology (CD68, CD3, CD20, macrophages), non decalcified histology to appreciate the structure of the peri implant soft tissues (Sulcus depth, junctional epithelium, connective tissue adhesion). Moreover: scanning electronic microscope (SEM) of the experimental abutment is performed to juge the cell adhesion on the abutment surface. The secondary endpoint is to assess clinical data, radiological bone remodeling regarding the different material. The hypothesis is that resin abutment lead to more inflammation than PEEK or titanium.
40 patients are included in the study, 20 patients in group 1 (=closure with composite material shaper; test group) and 20 patients in group 2 (=closure with custom-made zirconia oxide abutment; control group). Randomisation envelopes will be used for randomisation. Device under study: Straumann BLX, Roxolid® , SLActive® dental implants with a diameter of 3.5, 3.75, 4, 4.5 mm are used. Allogenic bone botiss maxgraft® cortical granules are used as graft material. Inclusion criteria: 1. Males and females at least 18 years of age or older. 2. One implant per patient. 3. Prior to any study-related activity, the subject must voluntarily sign informed consent, be willing and able to attend scheduled follow-up visits, and agree to the collection and analysis of pseudonymised data. 4. Lateral individual teeth (premolars and molars). 5. Class I extraction socket (intact buccal wall) or class II (1/3 of buccal wall). 6. The gingival contour of the tooth to be extracted - without recession. 7. Adjacent anterior teeth have no periodontal loss. 8. There are no implants in the adjacent teeth. 9. Non-traumatic tooth extraction, which results in intact walls of the socket. Exclusion criteria: 1. Deep occlusion (severe, class II). 2.

The aim is to clinically evaluate the effect of the alveolar sealing technique using a customised abutment on soft tissue volume changes following molar extraction and immediate dental implant placement.
