Immediate prosthesis over implants retained using abutments with flexible screws: A preliminary study.

Area of Science:

• Dental Implantology
• Prosthodontics
• Biomaterials Engineering

Background:

• Immediate loading protocols are increasingly favored for dental implant rehabilitation due to patient convenience.
• Conventional loading techniques can be time-consuming and less comfortable for patients.

Purpose of the Study:

• To evaluate a novel system of abutments with flexible screws for immediate dental implant loading.
• To assess implant survival, marginal bone loss, and patient/dentist satisfaction with this new system.

Main Methods:

• A preliminary study involved 8 patients receiving dental implants with immediate loading using flexible screw abutments.
• Analysis included implant survival rates, marginal bone loss measurements, and satisfaction scores.

Main Results:

• 35 implants were immediately loaded with the flexible screw abutment system.
• Implant survival rate after 12 months was 95.8%.
• Mean marginal bone loss was 0.51 ± 0.12 mm, with high patient (9.1) and dentist (8.5) satisfaction.

Conclusions:

• The flexible screw abutment system provides a viable alternative for immediate dental implant loading.
• It facilitates the quick and straightforward fabrication of a stable, passive-fit interim prosthesis.
• This system demonstrates efficacy and high satisfaction in clinical application.
