Basic information on the SURGICAL PROCEDURE - Straumann

Planning aids for implant selection
along with the vertical bone availability, the width of the alveolar ridge also plays an
important part. the orofacial bone around the implant should be at least 1 mm.
Diagnostic T
By using the Diagnostic t in the patient‘s mouth or on the cast, an initial impression of
the spatial relations for the choice of the implant sholder diameter and prosthetic reconstruction
can be obtained. the pictogrammes on the instrument show which arm is
used for which measurement. the Diagnostic t was developed as an aid and is used
for the initial diagnosis and to assist the dentist in determining the space requirement.
use of additional planning methods, such as use of a drilling template (see page 21
and 22), are recommended.
Diagnostic T (front)
X = Minimum occlusal space requirement
(for the lowest prosthetic restoration
variant)
Y = Interproximal distance (width of gap)
Z = Implant centre to adjacent tooth
(1/2 the width of the gap)
Diagnostic T (back)
Minimum vertical space requirement for
access with surgical instruments
Implant shoulders:
NN = Narrow Neck (Ø 3.5 mm)
RN = Regular Neck (Ø 4.8 mm)
WN = Wide Neck (Ø 6.5 mm)
