Distribution of risk factors for the displacement of a root in the maxillary sinus to assess whether there is any risk.
| Risk factors for displacement of a root in the maxillary sinus | |
|---|---|
|
|
|
| Practitioner-related factors | Patient-related factors |
| – Absence or limited oral surgery skills – Poor clinical and radiological analysis of the situation: lack of anticipation of potential complications – Absence or poor-quality imaging: blind avulsion – Left laterality and absence of adjacent teeth: limited dexterity |
– Loss of dental substances (voluminous caries, resorptions) or unfavorable anatomical features (long, thin, hook-shaped, or bell-shaped roots): complex avulsion with a fracture risk – Proximity to the sinus: + + + palatal roots of molars or premolars – Significant sinus pneumatization: age-related, progressive edentulous and ethnic (e.g. Asians have less voluminous sinuses) |
