Risk of Late Implant Loss and Peri-Implantitis Based on Dental Implant Surfaces and Abutment Types: A Nationwide Cohort Study in the Elderly.

ABSTRACT:

Aim

This nationwide population-based cohort study aimed to assess the incidence of implant complication treatments, including implant removal procedures and peri-implantitis treatments, in relation to implant surfaces and abutment types.

Methods

Data from the National Health Insurance Service, covering approximately 50 million individuals, were used. Implants and abutments were categorized by codes, including surfaces such as resorbable blasting media, sandblasted large grit and acid-etched (SA) and hydroxyapatite coating, along with abutment structures (one-piece straight, two-piece straight, angled). The incidence of implant complication treatments was analysed using Kaplan-Meier curves and Cox proportional hazards regression (α = 0.05).

Results

The study included 2
