Association Between Early Implant Failure and Prosthodontic Characteristics

Area of Science:

• Dental Implantology
• Prosthodontics
• Quality Improvement in Healthcare

Background:

• Early dental implant failure can significantly impact patient outcomes and treatment costs.
• Identifying risk factors is crucial for improving dental implant success rates.
• Prosthodontic characteristics are potential contributors to early implant failure.

Purpose of the Study:

• To investigate associations between specific prosthodontic characteristics and early dental implant failure.
• To provide data for continuous quality improvement in patient care for dental implants.
• To identify modifiable factors influencing the success of dental implants.

Main Methods:

• Implant-level analysis of a prospective clinical database from 2000-2014.
• Evaluation of time to implant failure using Cox proportional hazards regression models.
• Assessment of associations between prosthodontic characteristics and early implant failure.

Main Results:

• Out of 8762 implants, 395 (4.5%) failed within the first year.
• No significant association found between early failure and cover screws or prosthesis use at placement.
• Use of a single crown was significantly associated with increased early implant failure (HR, 3.94).

Conclusions:

• Prosthesis type at implant placement and early mechanical complications were not linked to increased early failure risk.
• The use of single crowns may represent a higher risk for early dental implant failure.
• Quality improvement efforts should prioritize surgical decision-making to reduce complications and enhance implant survival.
