Long-term efficacy of hydroxyapatite-coated cylindrical implants

Area of Science:

• Biomaterials Science
• Dental Implantology
• Clinical Research

Background:

• Titanium alloy implants are widely used in dental restorations.
• Hydroxyapatite coatings enhance osseointegration and implant stability.
• Evaluating the long-term efficacy of coated implants is crucial for clinical practice.

Purpose of the Study:

• To assess the clinical efficacy of hydroxyapatite-coated cylindrical titanium alloy implants.
• To determine implant survival rates and identify failure criteria.
• To monitor soft tissue health and patient-reported outcomes.

Main Methods:

• A two-site clinical study involving 316 implants in 154 patients.
• Data collection at multiple stages: pre-surgery, surgery, loading, and follow-up visits.
• Implant performance analyzed using life table methodology and defined failure criteria (mobility, radiolucency, fracture, etc.).

Main Results:

• A surgical success rate of 96.4% was achieved, with 11 of 316 implants failing before prosthetic attachment.
• The Cutler-Ederer life table success rate reached 97.8% after 6 years of observation.
• No significant adverse events were reported during the study period.

Conclusions:

• Hydroxyapatite-coated cylindrical titanium alloy implants demonstrate high efficacy and a favorable safety profile.
• These implants represent an effective treatment modality for dental restoration.
• Long-term success rates support the use of this implant type in clinical settings.
