Projects

• Title
  • A Prospective, Single Blind, Crossover Clinical Trial to Assess the Outcomes of Computer-Engineered Complete Dentures using Impressions and Intra-Oral Scans of the Edentulous Arches
• Summary
  • Clinical and patient centred assessments of maxillary and mandibular complete dentures, fabricated using a commercially available CAD/CAM system. The prostheses were designed and fabricated using impressions and intraoral scans of the edentulous arches.

• Title
  • An in-vitro assessment of the retrievability of fractured dental implant abutment screws
• Summary
  • A clinical simulation to compare the relative effectiveness of a commercially available screw fragment retrieval kit and standard dental instruments in retrieving fractured abutment screw fragments from dental implants.

• Title
  • Definitive immediate restorations versus non-occluding provisional restorations in partially edentulous patients. A pragmatic multicenter randomized clinical trial.
• Summary
  • Assessing the clinical and radiographic outcomes of dental implants and restorations which were immediately loaded with definitive restorations or provisionally restored for four months prior definitive restoration.

• Title
  • Occlusal Stability of Bilateral Free-end Saddle Removable Partial Dentures
• Summary
  • Longitudinal assessment of the pattern of occlusal contacts in participants wearing bilateral free-end saddle removable partial dentures using a digital occlusal analysis system.

• Title
  • Use of a three-dimensional scaffold to study bone cell growth and differentiation on commercially pure titanium
• Summary
  • Mesenchymal stem cell behaviour and differentiation in 3D scaffold on titanium substrate.

• Title
  • Load-displacement evalutaion of fiber-reinforced resin composite fixed partial denture materials.
• Summary
  • Adhesive bridge framework models designed with commercially available fibre-reinforced resin materials and bonded to bovine enamel were subjected to simulated occlusal loading. Stiffness values were compared and SEM images obtained to assess behaviour of the specimens under loading and determine the suitability of the materials for clinical use. Results revealed that these materials are not suitable for clinical use intended because of widespread evidence of microscopic failure, which would presumably lead to eventual macroscopic or clinical failure.

• Title
  • Clinical and microscopic evaluation of periabutment soft tissue surrounding intraoral percutaneous commercially pure titanium implants, a pilot study.
• Summary
  • Intraoral skin grafts used to repair defects following ablative surgery for oral cancer which were used in association with dental implant abutments. The response of the peri-implant abutment tissue appeared as hyperplastic and inflamed. Biopsies of the intraoral skin grafts were prepared for histopathological analysis. X-ray diffraction analysis also completed to assess the presence of titanium particles in the tissue.
