Purpose:

The goal of this study is to ass ess the survival, marginal bone loss and complications around sing le-toothimplants on which immediate provisionalization was carried out.Patients and

Methods:

78 implants were placed in 57 patients56 after extraction and 22 in healed sockets. Immediatelyafter surgery provisional crowns 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 takenper patient. The marginal bone loss was measured and complications were recorded. The statistical analys is of thedata 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). Themean mesial bone loss was 0.2±0.4 mm and the mean distal bone loss was 0.2±0.4 mm. No statistically significantdiff erences were found between immediate or delayed implants. 67 implants sh owed a bone loss less than 1 mm,and 36 did not sh ow any bone loss at all.The main complications were the uncementing of the crowns (11 crowns ), the presence of cement remnants (10crowns ) and the development of apical lesions around implants (6 implants).

Conclusion:

With the limitations of this study, it can be concluded by saying that immediate restoration withsing le-tooth implants and provisional crowns may be cons idered as a predictable technique (AU)
