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

Study Overview
=================
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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Position of Implant Platform to marginal bone | 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. | At Baseline (T0) | 
| Marginal Bone Position at 8 Weeks | 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 | At 12 weeks (T1) after Baseline | 
| Marginal Bone Position at 12 Weeks | 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. | At 18 Weeks (T2) after baseline (T0) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Osseointegration | measure the ability of the implant to integrate in bone | At 12 weeks |
