Summary

Aim of the present study will be to evaluate if the platform switching and the flat abutment can modify the peri-implant marginal bone remodelling. A clinical assessment of the soft tissues will also be provided.

80 consecutively inserted dental implants will be included in this study. Maxillary and mandibular implants will be considered, both in frontal and posterior area. After 6 to 12 weeks, the definitive prosthetic abutment will be screwed and the temporary crown cemented. After 2 more months, the definitive porcelain crown will be delivered. The final outcomes will be collected after 1 year from implant insertion.

Data will refer to the following timing:

T0= implant installation T1= temporary crown cementation T2= definitive crown cementation T3= 1 year follow-up The 80 implants will be randomly divided into 4 groups of 20 implants each, with different implant/abutment design.

Group 1: Tapered T3 Standard Collar implants + GingiHue abutments Group 2: Tapered T3 Standard Collar implants + Tissuemax IL abutments Group 3: Tapered T3 Prevail implants + GingiHue abutments Group 4: Tapered T3 Prevail implants + Tissuemax IL abutments On x-rays, the mesial and distal Marginal Bone Level will be measured and compared among and between the groups at the 4 different timing.

Pocket Depth and Bleeding on probing (mesial, buccal, distal and lingual) will be measured at T0, T1, T2 and T3. Data will be statistically analyzed.
