[Resonance frequency analysis in immediate loading of dental implants]

Area of Science:

• Dental Implantology
• Biomaterials Science
• Surgical Procedures

Background:

• Immediate loading of dental implants offers reduced treatment duration.
• Assessing primary implant stability is crucial for successful outcomes.
• Insertion torque (IT) and resonance frequency analysis (RFA) are key metrics.

Purpose of the Study:

• To compare primary implant stability using IT and RFA (ISQ).
• To evaluate factors influencing implant stability in immediate loading scenarios.
• To correlate IT and ISQ values with surgical and implant characteristics.

Main Methods:

• Prospective study involving 14 patients and 53 MIS implants.
• Measurement of IT and ISQ for non-submerged loaded (NSL), non-submerged non-loaded (NSNL), and submerged (S) implants.
• Analysis of stability in relation to extraction vs. non-extraction sites, augmented vs. non-augmented sites, and implant location.

Main Results:

• ISQ values were 63.3 (NSL), 67.2 (NSNL), and 58.8 (S).
• IT values were 40.4 Ncm (NSL), 46 Ncm (NSNL), and 35.3 Ncm (S).
• Significant correlation found between ISQ and IT, and ISQ and implant diameter. IT differed significantly between maxillary and mandibular sites.

Conclusions:

• ISQ is a reliable indicator correlated with IT in immediate dental implant loading.
• Implant diameter is the primary factor influencing ISQ, not implant length, location, or bone augmentation.
• The study supports immediate implant loading protocols with predictable stability assessment.
