Introduction And Treatment Planning
This manual is designed to serve as a reference
guide for dental practitioners to utilize
Restorative Components and
instruments. BIOMET 3i Implant Systems have
been developed to meet the diverse needs of
patients and to offer practitioners a choice of
customized restorative techniques.
BIOMET 3i Implant and restorative component designs
provide practitioners with a wide range of restorative
options, including support for single tooth crowns, fixed
and removable prostheses and attachments for securing
overdentures. BIOMET
3i Implant and Abutment Systems
utilize proven restorative designs and provide clinicians and
patients with predictable treatment options.
General Information
This manual provides guidelines for surgical and restorative
practitioners and laboratory technicians in the use of the
BIOMET
3i Navigator
®
System For Guided Surgery. The
success of any dental implant system depends upon proper
use of the components and instrumentation. This manual is
not intended for use as a substitute for professional training
and experience.
Treatment Planning
Patient Evaluation And Selection
Several important factors must be considered when
evaluating a patient prior to implant surgery. The
presurgical evaluation must include a careful and detailed
assessment of the patient’s general health, medical history,
oral hygiene, motivation and expectations. If the patient’s
medical history reveals an existing condition or signals a
potential problem that may compromise treatment and/
or the patient’s well being, consultation with a physician is
recommended. In addition, the clinician should determine
if the patient presents with an acceptable anatomical
foundation that is conducive to implant placement. An
extensive intraoral examination should be performed to
evaluate the oral cavity for any potential bone or soft-
tissue pathology. The clinician should also determine the
periodontal status of the remaining teeth, the health of
the soft-tissue, the presence of occlusal abnormalities or
parafunctional habits, such as bruxism or crossbite and
any other conditions that could adversely affect the
restorative outcome.
Pre-Operative Planning
Proper treatment planning includes selection of
appropriate implant lengths, diameters and locations.
The number of implants is a fundamental consideration
for the long-term success of an implant supported
restoration. Before an implant is placed, the anatomical
foundation of the treatment area must be carefully
assessed.
During the presurgical restorative planning phase of cases
with immediate provisionalization, it is important for the
surgeon, restorative dentist and laboratory technician
to participate in determining the type of prosthesis and
restorative components that will be used. Such decision
making is critical for determining the location of implants
and should be finalized prior to implant surgery. A top-
down treatment planning approach is recommended,
whereby the final prosthesis is designed, implant locations
determined and restorative components selected prior to
initiating implant surgery.
Clinical information necessary for determining
appropriate treatment options includes but is not
limited to: determining vertical dimension, evaluating
the space available between the alveolar crest and the
opposing dentition to confirm that available space exists
to accommodate the proposed abutment and final
restoration, locating the position of important anatomic
structures and determining bone dimensions where
implants are to be placed. The height required by the
restorative components varies with the type of abutment.
Therefore, the surgeon and restorative dentist should
carefully evaluate abutment dimensions. Diagnostic casts
should be used pre-operatively to evaluate the residual
ridge and to determine the position and angulation of all
implants. These casts allow the clinician to evaluate the
opposing dentition and its effect on implant position. A
surgical guide is helpful in determining the precise intraoral
position and angulation of the implants and should be
included in the pre-operative treatment plan.
By visualizing the final design of the prosthesis prior to
implant surgery, both restorative and surgical clinicians have
the opportunity to identify potential restorative problems.
They can then make the necessary modifications to implant
selection, location and the overall treatment plan prior
to actually placing the implants, thus improving treatment
predictability and success.
