title: Long-term outcomes of implants placed after vertical alveolar ridge augmentation in partially edentulous patients: a 10-year prospective clinical study.
abstract: OBJECTIVE
  The aim of this study was to evaluate the long-term clinical results around non-submerged implants placed after vertical alveolar ridge augmentation.
  
  
  METHODS
  The original population consisted of two groups of partially edentulous patients (Clinical Oral Implants Research, 15, 2004, 73; Clinical Oral Implants Research, 18, 2007, 286), receiving a total of 82 implants, after a vertical bone augmentation of at least 4 mm. Following cementation of the fixed dental prostheses, patients were asked to follow an individualized supportive periodontal therapy (SPT) program for an appropriate clinical and radiographic follow-up.
  
  
  RESULTS
  At the 10-year examination, seven of the 41 patients were lost to follow-up. During SPT, additional antibiotic and/or surgical therapy was necessary in 18 implants, and four of these implants were removed for biological complications. The overall implant survival rate was 94.1%. The mean interproximal bone loss (BL) was 0.58 ± 0.57 mm.
  
  
  CONCLUSIONS
  The results of this study confirmed that implants, placed after vertical augmentation and followed by an adequate SPT, offer predictable long-term results. Nevertheless, patients whose bone atrophy was consequence of a previous history of periodontitis presented a statistically significant greater BL.
