A maxillary implant is an implant that is placed between the jaw and the maxillary sinuses. It is inserted during a sinus lift or augmentation, and is used to increase the amount of bone to support dental implants.[1] Implants are either inserted after drilling, or by using a non-drilling method known as the osteotome technique.[1] Issues such as bulging within the sinuses can occur with maxillary implants.[2][3]
Maxillary implants can also be made by using Choukroun's technique with subsinus filling material.[4] The material is used to stimulate natural bone regeneration. A clinical study of this technique detailed that all patients within the study had continuous stable implants six months after placement. It also showed a vertical bone gain in all subjects.[4]
Rhinoplasty
Numerous different types of material have been used as sinus implants during rhinoplasty procedures. Plaster of Paris is often used during rhinoplasty and implanted into the frontal sinus.[5] Implants used in rhinoplasty have also been reported to cause enophthalmos.[6]
Sinus stent
Steroid-eluting sinus stents maybe used in addition to endoscopic sinus surgery. They are, however, of unclear benefit as of 2015.[7]
