Double-blind randomized controlled trial study on post-extraction immediately restored implants using the switching...

Area of Science:

• Dental Implantology
• Periodontology
• Prosthodontics

Background:

• Immediate implant placement offers functional and aesthetic advantages.
• Platform switching is a technique that utilizes a narrower abutment on a wider implant platform.
• Evaluating soft tissue response is crucial for long-term implant success.

Purpose of the Study:

• To assess the soft tissue response to immediately placed implants using platform switching.
• To compare peri-implant tissue changes between platform switching and conventional abutments.

Main Methods:

• 22 patients received immediate implants in the maxilla.
• Implants were randomly assigned to platform switching (3.8mm abutment) or conventional (5.5mm abutment) groups.
• Peri-implant parameters including mucosal changes (REC), papilla height (PH), and bone fill (VHG) were measured over 25 months.

Main Results:

• All implants achieved osseointegration.
• The platform switching group demonstrated significant improvements in REC gain (+0.18 mm) and PH gain (+0.045 mm) compared to the control group.
• Bone fill percentages were high in both groups (97.4% vs 95.2%), with no significant difference.

Conclusions:

• Immediate implants with platform switching can achieve stable peri-implant soft tissues within a 2-year period.
• Platform switching may enhance soft tissue healing and stability around immediate implants.
