Healing of Bone/Soft Tissue to Different Abutment Biomaterials and the Impact on Marginal Bone Loss

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 ?

Conditions

• Bone Loss
• Inflammation

Interventions

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
