Summary

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 ?

Detailed 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

Conditions

• Bone Loss
• Inflammation

Interventions

Type	Name	Description
DEVICE	dental implants	place implant according fabricant guidelines, 2mm sub-crestally
DEVICE	Zirconia abutments	place zirconia abutment on the day of implant placement
DEVICE	Titanium Abutments	place titanium abutment on the day of implant placement
DEVICE	cad-cam acrylic abutments	place cad-cam acrylic abutment on the day of implant placement
PROCEDURE	Subcrestal	place implant 2mm below crestal bone
DEVICE	platform-switch	abutment platform is narrow than implant diameter
PROCEDURE	one-time one-abutment	place the final abutment on the day of surgery and not remove it
PROCEDURE	Torque 20 n/cm2	the amount of torque applied to the abutment
