Abstract
|
|
|
Adequate and favorable alveolar ridge is essential for aesthetic and functional implants prosthetic reconstruction.
However, it cannot be prevented from bone resorption in the normal healing process after tooth extraction, and even
before reaching the extraction, absorbing a substantial portion of the ridge is often caused because of periodontitis,
peri-apical disease and trauma. In particular, because the resorption occurs more frequently in the buccal than
palatal side of the ridge, many cases are terminated with non-aesthetic treatment.
Therefore, current report presents case of implantation after ridge preservation in the atrophic posterior maxilla. In
order to obtain favorable alveolar ridge, ridge preservation was implemented using deproteinized bovine bone and
collagen membrane. And four months later, the implant was placed with sinus floor elevation.
Through the ridge preservation, it was possible to place aesthetically and functionally better implant. Also, it could
reduce the amount of sinus elevation.
