VERTICAL BONE AUGMENTATION USING THE CORTICO-AUTOGENOUS TENTING
TECHNIQUE IN MODERATE DEFECT OF THE ANTERIOR MAXILLARY RIDGE
NMRR-20-755-54658 S1

Ahmad KTZ@Z, Norhayati A

Introduction: We presented an approach to place the dental implant on traumatic bone
loss of anterior maxillary ridge. Case report: A 19-years-old Chinese boy with post-treated
Le Fort II fracture, symphysis of mandible fracture, and dentoalveolar fracture who
requested dental implant to replace missing upper anterior teeth. Clinical examination
and cone-beam CT scan revealed moderate bone defect at the anterior maxillary ridge. A
careful plan consisted of bone augmentation using cortical bone from the right ramus of
mandible placed on the anterior maxillary ridge in tenting fashioned and filled with
xenograft. A consolidation period of 8 months was allowed before inserting the dental
implant. The defect on the anterior maxillary ridge was restored and two dental implants
were placed with good primary stability before bridge construction. Conclusion: This case
illustrated the technique and favourable outcome of bone augmentation using the
corticoautogenous tenting technique.
