and Mandibular Implant-Retained Bar Overdentures
Carried out on Oxidized (TiUnite) Replace Select Implants:

INTRODUCTION
T
he original Branemark protocol for successful implant osseointegration required a healing period of 3-6 months
during which the implants were submerged for protection from premature
1
loading. As a result, the use of provisional implants
during the osseointegration period, as a means of
stabilization of a full-arch interim fixed restoration,
has gained popularity in implant prosthodontic
treatment.2 Recently, implant reconstructive dentistry has strongly evolved into 1-stage surgery,3,4
such as immediate postextraction, implant placement,5 and immediate (occlusal/nonocclusal) loading.6,7 Nowadays, the cumulative implant survival
rate after 10-year-in-function ranges between
96.52% and 98.05% for implants placed in healed
and postextractive sites, respectively.8 One of the
main contributions to the successful, long-term,
clinical outcomes has been the development of an
oxidized implant surface that may improve bone-toimplant contact in virgin healed bone,7,8 as well as
regenerated bone. 9 On the other hand, the
treatment of periodontally susceptible patients is
still controversial. Patients with periodontitis often
experience early tooth loss that requires implant
therapy.10 Nevertheless, smoking and a history of

periodontitis have been associated with a higher
prevalence of peri-implantitis.11
Since their introduction in the early 1970s, fixed
partial dentures and implant-supported milled bar
overdentures have developed into reliable treatment options in cases of partial as well as total
edentulism in both the mandible and the maxilla.12,13 A high success rate for implant-retained
overdentures has been reported, even if some late
implant failures have been observed.14,15 Biomechanical evaluation suggests that implant overload
is a major contributor to cortical bone loss.16 A
favorable prognosis requires proper bar design and
selection of the attachment system, based not only
on retention or cost, but also on biomechanics since
the attachment is the most fragile link between
prosthesis and implant.17
This case report describes long-term results of a
patient with a history of trauma from a motorcycle
accident, chronic periodontal disease, recurrent
decay, American Society of Anesthesiology (ASA)
III clinical condition, insulin-dependent diabetes,
and previous implants that had not been restored.
The patient was treated in both jaws with multiple
extractions of all remaining teeth, immediate
implant placement, and implant-retained bar overdentures. Immediate provisional implants (IPIs)
were placed between submerged implants to
provide support and esthetics for a provisional
restoration during healing. A multifactorial approach as well as a clinician-patient relationship
was needed in order to ensure optimal treatment
planning and a long-term successful result.
