Clinical Advantages of Immediate Posterior Implants With Custom Healing Abutments: Up to 8-Year Follow-Up of 115 Cases.

ABSTRACT

PURPOSE: Proper management of the soft tissues around dental implants is crucial to their long-term function and esthetics. The purpose of this article is to report the survival rate of immediate posterior implants when using an immediate chair-side technique for custom healing abutments. MATERIALS AND METHODS: The investigator implemented a retrospective case series analysis of a sample of 115 consecutive patients with 1 posterior dental implant placed between February 1, 2012 and December 9, 2014, in the author's private practice who underwent the previously published technique for immediate custom chair-side healing abutment fabrication. In this descriptive analysis, the primary outcome variable was implant survival. Other variables included patient gender and age. RESULTS: Of the 115 patients in this cohort, 66 were female and 49 were male, with a mean age of 58 years, with 73% of the sites being first molars and 27% second molars. This study sample had a 98.26% overall implant survival rate with 3 implant failures. Median follow-up time was 1 year with identical 1-year and 5-year survival rates. Follow-up at up to 8 years demonstrated a 98.26% overall survival rate with 100% survival in the maxilla and 96.08% in the mandible. CONCLUSIONS: This case series demonstrates that the Anatomic Harmony Abutment technique, by applying principles of flapless posterior immediate implant surgery with immediate custom healing abutment placement, can lead to highly successful implant outcomes.
