Objectives:
The aim of the present study was to present results of single molar area rehabilitated by 2 narrow diameter dental implants.
Methods:
A retrospective cohort of 33 consecutive patients from 2 private practices between the years 2008 and 2009 had been evaluated. Patients who had a first molar single replaced by 2 narrow diameter implants (3 mm wide) were included in this case series. Patients' demographics, site and implant characteristics, and time of follow-up were recorded from the medical files.
Results:
Overall, 33 patients received 66 implants replacing 33 missing first molars. Patients' age ranged from 23 to 76 years with an average of 49.2 ± 12.7 years. Most of the implants were used to replace a mandibular molar (76%) and 16 were used to replace 8 maxillary molars. In 2 patients, immediate implantation was performed. The mean distance between the adjacent teeth was 12.1 ± 1.0 mm. Follow-up time ranged from 10 to 18 months (average, 12.2 ± 1.9 months). All implants survived the follow-up time. One implant presented with 1 mm of bone loss at 12-month follow-up.
Conclusion:
Replacing a single missing molar with 2 narrow diameter dental implants might serve as a viable treatment option providing good and predictable long-term results.
