(The influence of locally delivered vitamin D3 on alveolar ridge preservation after tooth extraction (a clinical, radiographic and histological evaluation

Abstract

The healing process following tooth removal often resulted in a more pronounced reabsorption on the buccal aspect of the ridge than on its lingual/palatalcounterpart,and it includes dimensional changes in size and shape( Schropp et al., 2003 ,lindhe et al., 2005).

The reduction of alveolar bone volume following tooth extraction may interfere with placement of implants and affect the treatment and success of fixed or removable prosthesis with regard to function and esthetics (Seibert et al., 1996, Schneider et al., 1999, Schropp et al., 2003). So, alveolar ridge preservation (ARP) has become a key component of contemporary clinical dentistry(osburn, 1974).Systematic reviews have demonstrated that different alveolar ridge preservation techniques do not totally eliminate post-extraction resorption. ( Horváth et al., 2013 ,Morjaria et al., 2014 ).

Dental research has focused on improving bone substitutes by morphologic or biochemical modification (Guirado et al., 2010; Ruız et al., 2011). The application of biological mediators can improve peri- implant bone quality and quantity, reducing economic costs and treatment times, and consequently improving long-term outcomes. Among the biological mediator is vitamin D3.
