PDF: Use of Homologous Bone Grafts in Maxillary Sinus Lifting

Homologous bone has been considered a viable alternative in bone reconstruction in the posterior maxillary area to perform surgeries for the maxillary sinus lifting.

The aim of this study was to perform a literature review about the advantages and risks inherent in the use of homologous bone graft coming from the tissue bank to perform the surgery for maxillary sinus lifting.

After reading the titles and abstracts of the manuscripts, 69 studies were selected because of their correlations with the aim of the current study. 

The use of homologous grafts from bone banks showed greater osteogenic potential and a slow remodeling least compared to other grafts to increase the volume of the posterior bone of the maxilla in surgery for maxillary sinus lifting.

The maxillary bone atrophy is usually caused by loss of teeth, infections, trauma, tumor resections and/ or developmental abnormalities.

Such lesions, besides not repairing themselves spontaneously, are enhanced by the absence of stimuli, affecting the form and function of the skull.

The loss of teeth causes the narrowing of alveolar bone crest width, loss of height and reduction of cancellous bone. Thus, stimuli that maintain the morphology of the alveolar bone are lost with the teeth absence.
