Brief summary

Tooth extraction or loss results in resorption of bone volume in the jaw. This is a natural phenomenon which occurs mainly during the first 3 months following removal of the tooth. Preservation of bone volume facilitates subsequent placement of dental implants and leads to improved functional and aesthetic outcomes for patients. Guided bone regeneration (GBR) is a commonly used technique where a bone substrate (autologous or de-proteinised bovine bone matrix) is packed around the exposed implant to fill the defect, and covered with a membrane. The membrane promotes the growth of new bone by occluding infiltration of competing soft tissue, but permitting fluid and nutrient transfer to the newly forming bone. Native collagen membranes of porcine origin are commonly used as they have been proven to significantly enhance periodontal and bone regeneration in animal and human clinical studies. Celgro(tm) is an acellular type I/III collagen matrix of porcine origin. The product consists of natural collagen bundles without cross-linking or chemical additives. It is free from animal-derived DNA and pathogens of porcine origin. Celgro(tm) is a next-generation membrane that is manufactured using collagen originating from animals bred and exclusively raised in Australia, eliminating disease transmission concerns associated with foreign products. Additionally, the collagen bundle structure of Celgro(tm) is mechanically stronger and more elastic than other collagen membrane products of this type. This study proposes to use Celgro(tm) in a standardised dental implantation procedure to assess its suitability for use in GBR.

Interventions

Patients who are undergoing dental implant surgery with bone augmentation will receive Celgro(tm) collagen membrane as a part of the bone augmentation procedure instead of a commercially-available collagen membrane. The membrane is placed in the jaw during implant placement surgery, which is a single occasion.
