2. • Determine the optimum mini implant body size (length and
diameter):
• The 1.5mm diameter is selected for interproximal insertions while
the 2.0mm size is reserved for sites with good root clearance.
• A long (9mm) body length is ideal for posterior maxillary sites
whereas the shorter (6mm) length is better suited where less
cancellous bone depth and/or higher cortical depth occurs e.g.
anterior.
• Determine the optimum mini implant neck length.
• The short neck versions are preferred except where the mucosa is
thick e.g. edentulous and palatal sites. The tissue thickness may
be checked using a periodontal probe
