title: Immediate temporary restoration of single-tooth implants: Prospective clinical study.
abstract: OBJECTIVE
  The goal of this study is to assess the survival, marginal bone loss and complications around single-tooth implants on which immediate provisionalization was carried out.
  
  
  METHODS
  78 implants were placed in 57 patients: 56 after extraction and 22 in healed sockets. Immediately after surgery provisional crows were delivered without contacts in both centric and excursive jaw movements. The final crowns were inserted between 3 to 6 months later. During the study there were 3 x-rays taken per patient. The marginal bone loss was measured and complications were recorded. The statistical analysis of the data was carried out with the STATA 10® software.
  
  
  RESULTS
  The mean duration of the study was 92 weeks. Survival rate was 98.7% (1 failure out of 78 implants). The mean mesial bone loss was 0.2 ± 0.4 mm and the mean distal bone loss was 0.2 ± 0.4 mm. No statistically significant differences were found between immediate or delayed implants. 67 implants showed a bone loss less than 1 mm, and 36 did not show any bone loss at all. The main complications were the uncementing of the crowns (11 crowns), the presence of cement remnants (10 crowns) and the development of apical lesions around implants (6 implants).
  
  
  CONCLUSIONS
  With the limitations of this study, it can be concluded by saying that immediate restoration with single-tooth implants and provisional crowns may be considered as a predictable technique.
