Multicentre Prospective Study Analysing Relevant Factors Related to Marginal Bone Loss: A Two-Year Evolution

Area of Science:

• Dental Implantology
• Prosthodontics
• Biomaterials

Background:

• Marginal bone loss (MBL) is a key indicator of implant health.
• Understanding factors influencing MBL is critical for long-term implant success.
• This study investigates variables associated with MBL in rehabilitated implants.

Purpose of the Study:

• To analyze variables associated with marginal bone loss (MBL) in dental implants.
• To evaluate MBL two years after prosthetic loading.
• To identify factors influencing the success of implant rehabilitation.

Main Methods:

• Prospective descriptive study conducted across three clinical centers.
• Data collected over two years post-prosthetic rehabilitation.
• Statistical analysis included logistic regressions and Chi2 tests.

Main Results:

• A total of 218 implants were analyzed.
• Significant associations found between MBL and age, gender, bone quality, implant diameter, prosthetic connection, implant model, restoration type, and insertion torque.
• Factors like age, gender, and implant diameter showed strong correlations with MBL.

Conclusions:

• Multiple factors significantly influence marginal bone loss two years after implant prosthetic rehabilitation.
• Meticulous implantological planning is essential for achieving successful implant rehabilitation outcomes.
