Correct answer: D — Quality of oral hygiene and maintenance
Long-term implant success is most strongly predicted by the quality of oral hygiene maintenance and adherence to a supportive maintenance program (regular professional cleaning, radiographic monitoring). Peri-implant mucositis and peri-implantitis (inflammatory conditions analogous to gingivitis and periodontitis) are the primary biological causes of implant failure. Risk factors include poor oral hygiene, smoking, history of periodontitis, diabetes, and inadequate maintenance. Implant design factors are secondary to biological maintenance.
