Wrong implant diameter/length selection for site
What it is
Selecting an implant diameter or length that does not match the surgical site anatomy, prosthetic requirements, or biomechanical demands. Too narrow risks fracture under load; too wide risks fenestration or dehiscence; too short risks inadequate bone-to-implant contact; too long risks nerve or sinus injury.
Why it happens
• One-size-fits-all mentality (using the same implant for every case) • Inadequate pre-operative measurements on CBCT • Not accounting for bone remodeling after extraction (ridge narrows 40-60% in first year) • Choosing length based on available bone without considering prosthetic crown-to-implant ratio • Not adjusting for bone quality — short implants in soft bone have higher failure rates • Inventory limitations: using what is in stock rather than what is ideal
