s. Implants are either inserted after drilling or by using a non-drilling method known as the osteotome technique. Issues such as bulging within the sinuses can occur with maxillary implants. Maxillary implants can also be made using Choukroun's technique with subsinus filling material. The material is used to stimulate natural bone regeneration. A clinical study of this technique detailed all patients within the study had continuous stable implants six months after placement. It also showed vertical bone gain in all subjects.


Rhinoplasty

Numerous different types of material have been used as sinus implants during
rhinoplasty Rhinoplasty ( grc, ῥίς, rhī́s, nose + grc, πλάσσειν, plássein, to shape), commonly called nose job, medically called nasal reconstruction is a plastic surgery procedure for altering and reconstructing the nose. There are two ty ...

is often used during rhinoplasty and implanted into the frontal sinus. Implants used in rhinoplasty have also been reported to cause enophthalmos.


Sinus stent

Steroid-eluting sinus stents maybe used in addition to endoscopic sinus surgery. They are, however, of unclear benefit as of 2015.
