Biomaterials Engineering

Background:

Maxillary sinus augmentation traditionally relies on autogenous bone grafts, posing significant surgical morbidity.
Tissue-engineered bone grafts present a promising alternative, potentially avoiding donor site complications.

Purpose of the Study:

To evaluate the clinical outcomes of maxillary sinus augmentation using tissue-engineered bone grafts combined with xenograft.
To assess the feasibility of subsequent dental implant placement and loading in augmented sinuses.

Main Methods:

A case series involving three patients undergoing bilateral maxillary sinus augmentation with tissue-engineered bone grafts and xenograft.
Implant placement at 6 and 12 months post-augmentation, with radiographic and clinical evaluations up to 18 months.

Histological analysis of biopsies to assess tissue regeneration and inflammatory response.

Main Results:

No adverse complications were reported during or after the procedures.
Successful insertion and loading of ten dental implants into the augmented sinuses.
Significant bone height increase (approximately 4.5-fold) observed, with mature bone formation and no signs of inflammation.

Conclusions:

Tissue-engineered bone grafts are effective for maxillary sinus augmentation, facilitating dental implant success.
The study demonstrates the feasibility of this regenerative approach for reconstructive dentistry.
Further controlled clinical trials are warranted to validate this evolving treatment modality.
