Abstract
Background: Patient wanted to restore her lost teeth with implants in the lower left first molar
and second premolar region. Cone beam computerized tomography (CBCT) revealed inadequate
bone width and height around future implant sites. The extraction socket of second premolar
area revealed inadequate socket healing with sparse bone fill after 4 months of extraction.
Aim: To evaluate the clinical feasibility of using a collagen physical resorbable barrier made
of human pericardium (HP) to augment localized alveolar ridge defects for the subsequent
placement of dental implants.
Materials and Methods: Ridge augmentation was done in the compromised area using
Puros® demineralized bone matrix (DBM) Putty with chips and an HP allograft membrane.
Horizontal (width) and vertical hard tissue measurements with CBCT were recorded on the
day of ridge augmentation surgery, 4 month and 7 months follow‑up. Intra oral periapical taken
1 year after implant installation showed minimal crestal bone loss.
Results: Bone volume achieved through guided bone regeneration was a gain of 4.8 mm
horizontally (width) and 6.8 mm vertically in the deficient ridge within a period of 7 months
following the procedure.
Conclusion and Clinical Implications: The results suggested that HP Allograft membrane may
be a suitable component for augmentation of localized alveolar ridge defects in conjunction
with DBM with bone chips.
