Basic information on the SURGICAL PROCEDURE - Straumann

Vertical implant position
the implant can optionally be submerged
in the bone as far as the margin of
the sLactive/sLa ® surface (a) or, for
esthetic reasons, as far as the level of
the implant shoulder (B). the vertical
position of the implant shoulder must be
borne in mind when preparing the
implant bed.
the following rule applies for the depth
of insertion to implant shoulder level (B):
SLActive/SLA ® surface + 2 mm =
depth of preparation
in the esthetic area the implant shoulder
should be approx. 1– 2 mm apical to
the enamel-cementum junction of the
contralateral tooth.
Dental gaps in the anterior region
in the anterior area, a deeper vertical
implant position is better for esthetic
reasons. in this situation, use of
standard Plus implants which have a
shorter smooth neck section of the
implant neck (1.8 mm) compared with
the standard implants (2.8 mm) is
recommended.
Oro-facial bone supply
important: the oro-facial layer of bone
around the implant must be at least
1 mm thick in order to ensure stable
hard and soft tissue conditions.
