This review evaluated the characteristics of vertical alveolar defects that were augmented via onlay bone
grafting or guided bone regeneration. Information regarding the anatomic site, type of edentulism, and defects’
dimensions were extracted. The experiments differed vastly in the description of the defects’ features. Aiming to
mitigate the confounding effect of recipient site’s morphology in future experiments, a classification of vertically
deficient recipient sites is proposed.
Key Words: alveolar bone defect, vertical ridge augmentation, onlay bone graft, guided bone regeneration
INTRODUCTION
P
resence of sufficient alveolar bone
volume is one of the principal prerequisites for implant treatment.1 A considerable part of recent research has been
directed toward distinguishing the most
favorable augmentation procedure for restoring
deficient alveolar ridges.1–3 Restoration of alveolar
vertical defects has remained a challenge in
reconstructive surgery.4,5 A variety of augmentation
techniques, namely onlay bone grafting (OBG), inlay
bone grafting, guided bone regeneration (GBR), and
distraction osteogenesis have been used for augmentation of vertical defects, using different types
of bone grafts and stimulating factors.3 The applicability of augmentation procedures, to a large
extent, depends on the recipient site morphology.6
On one hand, it influences choosing the optimal
treatment modality, given that the selection criteria

for different augmentation techniques are partly
established based on the characteristics of the
recipient site.7–9 In addition, the suitability of bone
graft options with different regenerative properties
should be determined in view of the regenerative
demands of the defect.10 On the other hand, the
regenerative potential of the recipient site is a major
factor for effective bone formation within the
augmented area.11 A bony region with compromised vascularization and cellularity shows suppressed healing ability.12 It has also been suggested
that the morphology of alveolar ridge significantly
affects bone regeneration.8
The focus of studies has been mainly on
improving the techniques and introducing novel
augmentation materials to provide more promising
outcomes. However, the variation among studies
does not allow for a generalized conclusion on the
effectiveness of the suggested protocols.1 This
inconsistency may be partly due to imprecise
consideration of the properties of recipient sites
within the study designs. To verify the validity of
this assumption, a systematic review was conducted
on experiments evaluating vertical alveolar ridge
augmentation as a pre-implant reconstructive
surgery. The aim was to assess the characteristics
