Compare the Success Rate of T3 Dental Implant (Biomet 3I) With or Without Platform-switch Concept

• Conditions: Implants; Bone Loss

• Registration Number: NCT01971268
• Lead Sponsor: Implantology Institute

Brief Summary

In patients that received a T3 (Biomet 3I) dental implant, does the use of platform-switch concept compared to the use of platform-matched concept, refrain marginal bone loss during osseointegration phase (t=12 weeks =T1) and from then to final rehabilitation (t= placement of the final restoration = at 18 weeks=T2)

Detailed Description

Patients from a private practice who received dental implants (T3 dental implant Biomet 3I) from November 2012 to October 2013 were eligible to enter the study.

Two groups were formed: one group received a T3 dental implant with platform switch concept and the other received an implant with platform matched type of connection.

We evaluate osseointegration at T1 (12 weeks) and marginal bone position in relation to the implant platform at baseline (implant installation) T0 and again at T1 and T2.

From data recorder in T0,T1 and T2, we evaluate changes in marginal bone position.

Primary Outcome Measures

Name	Time	Method
Position of Implant Platform to marginal bone	At Baseline (T0)	Compare marginal bone position at baseline T0 (measured radiographically (digital) from the most coronal position of marginal bone to the most coronal position of the platform, measured in the most mesial and distal part (two measures) of the implant platform.
Marginal Bone Position at 8 Weeks	At 12 weeks (T1) after Baseline	Compare marginal bone position at T1, 12 weeks after baseline (T0) (measured radiographically (digital) from the most coronal position of marginal bone to the most coronal position of the platform, measured in the most mesial and distal part (two measures) of the implant platform
Marginal Bone Position at 12 Weeks	At 18 Weeks (T2) after baseline (T0)	Compare marginal bone position at T2, 18 weeks from baseline (T0) (measured radiographically (digital) from the most coronal position of marginal bone to the most coronal position of the platform, measured in the most mesial and distal part (two measures) of the implant platform.

Secondary Outcome Measures

Name	Time	Method
Osseointegration	At 12 weeks	measure the ability of the implant to integrate in bone
