Health of Young European Families and Fish Consumption

OverweightMetabolic Syndrome X1 more

This is a controlled, randomized, intervention trial (CRIT) with 20-40 year old overweight individuals (n = 320) across Europe in order to distinguish between biologically active components of seafood, i.e., seafood proteins and n-3 lipids, regarding their effects on risk factors for metabolic syndrome, bone health, and weight management.

Lateral Ridge Augmentation Around Implants

Alveolar Bone Resorption

The rehabilitation of dentoalveolar defects and tooth loss has seen remarkable advancements over time. Extraction of tooth leads to reduction in physiologic dimension of bone and it is imperative to evaluate the site before implant placement. To overcome the loss of volume and to avoid complications, procedures to restore the resorbed alveolar bones prior to or during implant placement are usually performed. Lateral bone augmentation procedures with guided bone regeneration (GBR) are well documented in the literature with predictable results. It generally involves bone substitute xenograft and bioresorbable membrane combined with implant placement in single stage procedure or separately in two- stage procedure. As the search for better and improved materials continues, a porcine derived ribose cross-linked volumising collagen matrix (VCMX) based on GLYMATRIX® technology has been introduced which showed benefits over the conventional membranes in terms of simplified procedure, degradation, membrane exposure and healing. The collagen scaffold has been reportedly used as a core material for guided bone regeneration, when there is sufficient bone to place an implant but a horizontal defect is present in the crestal ridge. As part of augmentation VCMX is designed to expand and ossify during healing. The advantage of the material is that when placed in one or two layers, it may eliminate the use of bone substitute or connective tissue graft thus simplifying the augmentation procedure. In addition, adding a bone substitute is a valid option based on indication. In the quest of better material and simplified procedures, few authors have performed case studies based on application of VCMX for guided bone regeneration around dental implants and has shown promising results. However, there are no controlled clinical trials on application of VCMX for lateral ridge augmentation. Thus, the present study aims to assess the efficiency of VCMX compared to resorbable collagen membrane (RCM) and bone graft (BG) for lateral ridge augmentation around implants through a well designed, controlled clinical trial.

Ridge Preservation Using Xenogenic Bone Graft and Pre-hydrated Collagen Membrane

Alveolar Bone ResorptionEdentulous Alveolar Ridge

This pilot multicentric randomized controlled clinical trial is aimed at evaluating the composition of the new-formed tissue into the dental socket after 6 months from tooth extraction and the application of a combination of xenograft bone granules and collagen membrane. Extraction sites will be either grafted with Dentsply Symbios Xenograft Granules and covered with Dentsply Symbios pre-hydrated Collagen Resorbable Membrane or grafted with Geistlich Bio-Oss Collagen and covered with Geistlich Bio-Gide membrane. Results will be compared to spontaneous socket healing.

Guided Bone Regeneration With Customized Titanium Meshes

Bone Resorption

The aims of this prospective clinical study are to evaluate: a) the effectiveness of digitally customized titanium meshes in association with autologous bone particles and bovine bone mineral and covered with collagen membranes for the regeneration of atrophic edentulous sites; b) the survival rate of implants placed in the reconstructed areas; and c) new bone regeneration from a histomorphometric point of view

Outcome of Implant-supported Overdentures

Alveolar Bone LossBone Resorption3 more

The aim of this pilot study was to assess survival rates and peri-implant bone loss of two narrow-diameter titanium-zirconium implants supporting maxillary and mandibular overdentures during an observation time of 3 years. The masticatory performance, self-reported chewing ability and change of oral health impact profile (OHIP) after rehabilitation were also investigated.

Modified Ridge Splitting Technique Using Autogenous Bone Blocks (MRS)

Alveolar Bone ResorptionAlveolar Ridge Enlargement

In this clinical study ridge splitting procedures are preformed using autogenous bone blocks. After a 3-month healing, at the time of dental implant placement bone core biopsy samples are harvested. The samples undergo micro-Ct and histomorphometric analysis.
