Abstract
One 60 years-old patient was scheduled for left posterior maxillary ridge augmentation due to failure of standard implants, followed by successful maxillary dental implants. We used an unproved technique consisting in a mixture of 50% allogenic and 50% xenogenic bone supported by reabsorbable membrane. No complications were found at the different stages of the treatment, and at the ending the patient showed a good level of satisfactory outcomes. Radiological evaluation demonstrated ridge augmentation able to support implant, and within the graft islands of connective and bone-like tissue was found. Within these tissues osteoclasts and osteoblast putative cells were found. Results demonstrate that the used method in addition to support implants has osteogenic and bone remodeling activity.
Highlights
The endosseous implants have revolutionized modern dentistry, with a constantly increasing number of patients seeking replacement of lost teeth with this modality of treatment [1]
At present, guided bone regeneration with particulate graft materials and resorbable collagen membranes is an effective technique for alveolar horizontal ridge augmentation and dental implants [9,10]
We present one case of patient in which maxillary vertical ridge augmentation, followed by successful maxillary dental implants, was achieved through an unproved technique consisting in a mixture of allogenic and xenogenic bone supported by reabsorbable membrane and no tent screws
Summary
The endosseous implants have revolutionized modern dentistry, with a constantly increasing number of patients seeking replacement of lost teeth with this modality of treatment [1]. To ensure the successful of dental implants placement, the volume (both vertical and horizontal) and quality of the alveolar bone are critical. At present, guided bone regeneration with particulate graft materials and resorbable collagen membranes is an effective technique for alveolar horizontal ridge augmentation and dental implants [9,10]. We present one case of patient in which maxillary vertical ridge augmentation, followed by successful maxillary dental implants, was achieved through an unproved technique consisting in a mixture of allogenic and xenogenic bone supported by reabsorbable membrane and no tent screws. The mixture of allogenic and xenogenic bone substitutes has the advantage of different granule-. Sizes that presumably enhances in growth of the new formed bone into de implant, as well as the removal of the implanted material
