SINUS BONE GRAFT WITHOUT GRAFT MATERIALS: A CASE REPORT PART2

SINUS BONE GRAFT WITHOUT GRAFT MATERIALS: A CASE REPORT PART2

We had believed that sinus bone graft needs living autogenous bone or other graft materials not alive  for resisting air pressure that gradually resorbs the bottom the sinus as a result. However, can the fact that needs some graft materials be true?

Dr. Jensen wrote that …….in 1997, I observed a strange phenomenon in a maxillary fracture patient. A unilateral ossification of the maxillary antrum occurred following a Le Fort III fracture that had been treated the year before. I wondered how trauma around the antrum due to an impacted maxilla and the inferiorly displaced orbital rim could lead an ossified maxillary sinus…………This unusual finding remained a mystery to me for many years…….He (Phil Boyne) found that preservation elevated sinus membrane created a confined space in which bone had the potential to form. 1)

Until now, clinicians had found that maxillary sinus had a potential for bone reformations without any bone graft materials.2)3)

The case of non-smoker 60 years female patient shows below also sinus bone graft without bone graft material and implants placement simultaneously.
