Analysis of Dental Implants with Bio Ceramic Apatite Wollastonite (AW) and Hydroxyapatite (HA) Coatings by Pulsed Laser Deposition
Thomas, Betsy Sara / Mapara, Manjeet
Purpose Statement: A unique attempt to create a next generation of a surface treated dental implant.
Introduction: After the initial enthusiasm and interest in hydroxyapatite products subsided due to dissolution of the coatings and failure at the coating interface, this was a unique attempt to create a next generation of dental implant.
Materials and Methods: The adhesion property of AW and HA coatings at various temperature by pulsed laser deposition was assessed on titanium plates. Indigenously prepared dental implants were coated with AW/HA by pulsed laser deposition and was implanted in the femur of rabbits . Histomorphometric evaluation was done at various intervals.
Results: Decohesion load was more for AW in scratch test and more bone formation around AW coated implants on histological evaluation.
Discussion: AW coating by pulsed laser deposition was more adherent to the titanium surface and led to faster bone formation than HA.
Conclusion: This experiment opined that AW coated by pulsed laser deposition seems to be a promising method in achieving bioactive coatings on titanium implants.
