Summary
Maxillary dental implants exceeding 4mm into the sinus, peri-implantitis, and bone graft issues are linked to implant-related odontogenic sinusitis (IR-ODS). These complications significantly increase the risk of developing IR-ODS.
Area of Science:
- Otorhinolaryngology
- Oral and Maxillofacial Surgery
- Medical Imaging
Background:
- Odontogenic sinusitis is a growing concern with increased use of maxillary dental implants.
- Understanding the factors contributing to sinusitis after dental implant placement is crucial for patient outcomes.
Purpose of the Study:
- To investigate the association between maxillary dental implant extrusion into the sinus and implant-related complications in patients with implant-related odontogenic sinusitis (IR-ODS).
Main Methods:
- A case-control study involving 60 patients undergoing surgery for IR-ODS.
- Retrospective analysis of preoperative sinus computed tomography scans comparing 68 IR-ODS sinuses with 27 control sinuses.
- Statistical analysis, including odds ratio calculations, to determine associations with IR-ODS.
Main Results:
- Implants extruding over 4mm into the maxillary sinus were significantly associated with IR-ODS (adjusted OR 27.4).
- Peri-implantitis (adjusted OR 11.8) and disrupted-extruded bone grafts (adjusted OR 34.1) also showed a significant association with IR-ODS.
- These findings were statistically significant (p < 0.05).
Conclusions:
- Maxillary dental implants extending more than 4mm into the sinus are strongly linked to IR-ODS.
- Peri-implantitis and complications with bone grafts (disruption and extrusion) are significant risk factors for developing IR-ODS.

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
