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)
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.
Study Type
OBSERVATIONAL
Enrollment
50
place dental implants according to manufacturer guidelines
Place Dental Implant with an abutment narrower than the implant platform
Place Dental Implant with abutment with same size as the platform
Instituto de Implantologia
Lisbon, Lisbon District, Portugal
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.
Time frame: 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
Time frame: 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.
Time frame: At 18 Weeks (T2) after baseline (T0)
Osseointegration
measure the ability of the implant to integrate in bone
Time frame: At 12 weeks
