About

In patients that require a dental implant, does zirconia compared to titanium, or cad-cam acrylic abutments, provide less inflammation, marginal bone loss or infection during the osseointegration period ?

Full description

Place dental Implants and zirconia, titanium, acrylic or cad-cam acrylic abutments, torque to 20 n/cm2 Evaluate Changes in inflammatory levels from T0 (baseline) to T7-12 weeks (measure intermediate points at T0 (baseline),,T1-8 Weeks and T2-12 weeks) Also evaluate outcomes marginal bone loss, gingival height levels and osseointegration
