A Non-Interventional Study Documenting Use and Success of Tissue Level Implants

Area of Science:

• Dentistry
• Oral Implantology
• Biomaterials Science

Background:

• Randomized controlled trials (RCTs) on dental implants often use strict criteria, potentially limiting generalizability to daily practice.
• Understanding implant behavior in routine clinical settings is crucial for evidence-based dentistry.

Purpose of the Study:

• To document the performance and outcomes of screw-shaped, tissue-level dental implants in a non-interventionist, multicentric trial reflecting daily practice.
• To evaluate implant success, survival rates, stability, crestal bone changes, and patient satisfaction over two years.
• To compare implant outcomes in daily practice versus controlled study conditions.

Main Methods:

• A multicentric, non-interventionist trial involving 196 screw-shaped, tissue-level implants.
• Clinicians selected implant type, surgical, loading, and prosthetic protocols without predefined inclusion/exclusion criteria.
• Data collection included implant parameters at surgery, implant stability quotient (ISQ), crestal bone level changes, and patient satisfaction up to two years post-placement.

Main Results:

• High success rate (98.31%) and survival rate (98.79%) were observed.
• Implant stability quotient (ISQ) increased from 68.61 ± 10.35 at surgery to 74.39 ± 9.64 at 2 years.
• Mean crestal bone loss was observed, with mesial distances changing from 1.25 mm to 2.04 mm and distal from 1.68 mm to 2.16 mm over two years.
• High patient satisfaction (69.3%) was reported at the 2-year follow-up.

Conclusions:

• Dental implants demonstrate high success and survival rates when used under standard, non-interventionist daily practice conditions.
• Implant stability and bone levels show predictable changes over two years, consistent with findings in controlled studies.
• The outcomes suggest that implants are a reliable treatment option in routine dental practice, achieving results comparable to those in highly controlled research settings.
