ABSTRACT
Background: To date, only
few studies have reported on the clinical outcomes of immediate
postextraction implant placement and immediate loading.
Purpose:
The purpose of this retrospective study was to report the results of
immediately loading four implants placed in fresh extraction sockets in
the mandible after a follow-up of 24 months.
Materials and Methods:
Between January 2001 and January 2009, 50 patients (28 women and 22
men, average age 54 years), had 347 teeth extracted and a total of 200
dental implants placed in the mandible. The patients received a
provisional fixed bridge the same day and a permanent one 3 months
later. Clinical checkups were performed after 1, 2, 3, 6, 12, and
24 months. Marginal bone measurements were made in intraoral radiographs
taken 1 day after surgery and after 1 year. A questionnaire was used to
evaluate self-perceived factors related to comfort, aesthetics, and
function.
Results: All bridges were
stable and no implant failures were recorded during the follow-up,
giving a survival rate of 100%, at 2 years. The marginal bone loss
amounted to 1.33 ± 0.36 mm after 1 year and 1.48 ± 0.39 mm after
2 years. Ten patients showed prosthetic complications with the
provisional bridge, but all the definitive prostheses remained stable
throughout the study period without any complications. The patients
reported satisfaction with the treatment.
Conclusions:
The present retrospective study showed that immediate loading of four
implants immediately placed in extraction sockets is a valid treatment
modality for the totally edentulous mandible.
