Cortical Bone Plate Versus Cortico-cancellous Block Graft

Horizontal ridge augmentation using either cortical bone plate technique or cortico-cancellous block graft was the aim of the study. Bone quality was analyzed histomorphomterically, and horizontal dimensional changes were assessed using CBCT.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Eligible patients aged 18 years or older with partial edentulism of the mandible
  • The residual ridge width must be 4 mm or less
  • Intra-oral donor sites should be available in the external oblique ridge and symphyseal area

Exclusion criteria

  • Irradiation of the head and neck region
  • Intravenous bisphosphonate
  • Pregnancy
  • Smokers, alcoholics and drug abusers

Treatment and study plan

Split-block technique

Procedure

Horizontal ridge augmentation using the split-block technique where a cortical bone plate harvested from the external oblique ridge was split in half and fixed at a distance from the atrophied ridge. Then autogenous bone chips were packed in the gap between the plate and the ridge.

Cortico-cancellous block graft

Procedure

Horizontal ridge augmentation using a cortico-cancellous block harvested from the chin of the mandible.

Primary outcomes

    Histomorphometric analysis (Masson's Trichrome stain)

Secondary outcomes
