Assessing the Impact of Dental Implant Length on Early Failure Rates: A Retrospective Analysis.

INTRODUCTION

The selection criteria of implant is very critical. Implant length determines the mechanics of osseointegration.

OBJECTIVE

To investigate the influence of dental implant length on early failure rates, osseointegration success, peri-implant bone loss, and patient-reported outcomes.

MATERIALS AND METHODS

A retrospective analysis was conducted involving 124 participants who underwent dental implant placement. Implant lengths were categorized as short ( = 54), standard ( = 35), or long ( = 35) based on standard industry classifications. Baseline characteristics, implant lengths, and early failure rates within the first six months post-implantation were extracted from clinical records.

RESULTS

Preliminary analysis revealed variations in early failure rates among different implant length categories. Short implants demonstrated a distinct pattern of complications compared to standard and long implants. Early failure rates were 8% for short implants, 4% for standard implants, and 2% for long implants ( = 0.04). Osseointegration success rates were 90%, 95%, and 98% for short, standard, and long implants, respectively. Peri-implant bone loss was 1.5 mm, 1.0 mm, and 0.8 mm for short, standard, and long implants, respectively ( = 0.02). Patient-reported outcomes indicated higher satisfaction levels in the long implant group ( = 0.03).

CONCLUSION

The study highlights the importance of considering implant length in clinical decision-making and suggests potential associations with osseointegration success, peri-implant bone loss, and patient satisfaction.
