title: Predictability of staged localized alveolar ridge augmentation using a micro titanium mesh.
abstract: OBJECTIVE
  The aim of this study is to retrospectively evaluate the success rate of staged localized alveolar ridge augmentation using titanium micromesh. In addition, the factors that influenced the success were analyzed.
  
  
  METHODS
  Twenty-three alveolar ridges (posterior mandible 12, anterior maxilla 7, anterior and posterior maxilla 3, and posterior maxilla 1) were augmented using titanium micromesh and were retrospectively assessed.
  
  
  RESULTS
  Thirty sites were judged as successful with a success rate of 56.6 % (posterior mandible 58.3 %, anterior maxilla 57.1 %, anterior and posterior maxilla 33.3 %, and posterior maxilla 100 %). The span of the augmentation site was significantly correlated with the success rate (goodness test of fit for chi-square, p < 0.05). The success rate was low if infection of the grafted material was observed, while the exposure of titanium mesh had no negative impact.
  
  
  CONCLUSIONS
  This limited study suggested that the predictability of augmented bone volume in staged alveolar ridge augmentation using titanium micromesh was not sufficient to expect an ideal and planned implant placement. The success was influenced by the distance of the augmentation site and the infection of the graft material, which were associated with moderate to severe vertical ridge resorption and/or mechanical and functional loading on the surgical site.
