ABSTRACT
AIMS:
The primary aim of this study was to evaluate the 1-year crestal bone loss and success rate of an immediately placed single-stage implant placed and restored by novice operators. A secondary aim was to determine the patient's assessment of the appearance of the final restoration.METHODS:
Fifty-one patients received a tooth extraction and placement of at least 1 immediate implant by a Graduate Periodontics resident. Clinical and radiographic measurements were taken at the surgical, 4-month, and 1-year follow-up visits. After at least 3 months healing, dental students restored the implants with either a crown or an overdenture. Patient satisfaction was assessed using 5 categories excellent, very good, good, fair, or poor.RESULTS:
Sixty-two immediate implants were placed. The success rate was 100% at the 12-month visit and was subclassified as grade 3 because of the mean first year bone loss of 1.3 +/- 1.0 mm. Using the 2008 classification of Misch et al, 42 implants were classified as success optimum health, 19 as survival satisfactory health, and 1 as survival compromised health. Radiographic bone loss was stratified by implant platform position relative to the alveolar crest and changed from time 0 to time 12 by -1.0 +/- 1.2 mm for the supracrestal group (n = 25, P < 0.05), -1.5 +/- 0.9 mm for the crestal group (n = 31, P < 0.05), and -1.3 +/- 1.2 mm for the subcrestal group (n = 6, P < 0.05). The supracrestal group had significantly less bone loss than either the crestal or the subcrestal group (P < 0.05). The appearance of the final restoration at 1 year was rated excellent by 82% of patients, very good by 16%, and good by 2%.CONCLUSIONS:
Immediate implant placement by novice operators using routine dental school procedures was a highly predictable procedure as indicated by the 100% success rate at 12 months. Most patients rated the restoration appearance as excellent.
