The document discusses the history and development of mini dental implants (MDIs) from their origins in the 1970s to their current use, including that MDIs are small diameter titanium implants used to stabilize dentures or partial dentures for patients lacking sufficient bone quantity or quality for standard dental implants. It provides details on the structure, uses, benefits, and limitations of MDIs as well as the surgical procedure and prosthetic process for placing and restoring MDIs.

1. AKA
Small-Diameter Dental Implants

2. 1940s, the
metal implant
was first born
as a
subperiosteal
implant.
1960s that the
root form
(invented by
Dr. Brånemark)
made its
debut.
. Derived from
the root form
that was born
in the 1970s,
the mini-
dental implant
was being
developed and
modified as
early as 1976
Mini-implants,
which were
first developed
by Dr. Victor I.
Sendax of New
York
Dr. Ron Bulard
then
developed
mini dental
implants
(MDIs) as a
way to
stabilize
removable
prosthetics
and later
marketed by
IMTEC
Corporation in
the 1990s
FDA approval
for long-term
use of its MDI
mini-dental
implant
devices in
2002

3. MDIs are generally constructed
from titanium
either sprayed with calcium
phosphate, or contain it along
the length of the screw
portion.
The head portion of the
implant looks very much like a
ball.
This ball fits firmly into the
retaining mechanism( metal
housing) and together these
structures hold the dentures at
a designated level.

4. Use of SDIs in Approximate Order of Decreasing
Frequency of Use
•Edentulous mandible
•Removable partial denture
•Edentulous maxilla (this use has higher failure rate
than edentulous mandibles)
•Augmentation of fixed prosthesis
•Sole support of fixed prosthesis
•Salvage of previously made prosthesis

5. Easier cleaning.
Firmer denture fit.
High success rate. Less
discomfort.
No cutting or sutures.
No need for adhesives
or messy bonding
agents.
No slipping, wobbling
or discomfort.
Permanent results.
Quick treatment time.
Reduced costs.
Used in patients with
inadequate bone
quantity (linguo-facial)
Can be used in
patience with
Compromised Physical
Condition

6. MDIs have substantially lower bite force
tolerance than standard implants, which
may make them more likely to bend or
break over time.
Vertical bone requirement
Since the mini implants require bones to
support them, they cannot be used in an
area of the jaw with inadequate vertical
bone or if there has been too much
bone loss.
Teeth Grinding
You might not be a good candidate for
mini dental implants if you grind your
teeth regularly as it may wear them
down prematurely.

7. If you aren’t a candidate for conventional
implants you cannot install mini implant
◦ a patient who did not have sufficient bone thickness to accept a
couple large implants to anchor a full plate can get a structurally-
superior solution by distributing the load evenly among four to six
mini-implants.
Mini implants will feel awkward in my mouth
◦ they look and feel just like your own natural teeth
◦ kinder impact on gum tissues and bone
Mini implants aren’t a long-term solution
◦ It preserves oral health, including gum health and healthy bone, better
than other types of replacement teeth
There are disadvantages to installing mini dental
implants
◦ most disadvantages are the result of poor planning or inexperienced
practitioners.

8. Clinically, measure bone
thickness using caliper
(min. of 4mm needed)
Measure thickness of
mucosa using
periodontal probe
Radiograph: determine
vertical and horizontal
bone height
Place metal markers in
old dentures to
reference position of
foramen mentalis
Digital planning of
position of implants

9. 1. Local Anesthesia
2. Template - transfer of distal
implantation site
3. Use probe to set bleeding
point on the mucosa
4. Pilot drill – single use only.
Used as parallel post.
5. Drilling should be done with
saline solution as external
cooling
6. implants must be placed
slowly. Short break in each
quarter turn to prevent
thermal damage
7. Thumb wrench is used when
resistance gets high
8. graduated torque wrench for
last winding and postion

10. 1. Take impression: soft silicone material
2. Imprints will be transfer to the resin
3. Extend the marks to ensure contact free
seating of the metal housing and
prosthesis
4. blockout shim (silicone rings) are used
so that no prosthetic resin will flow
under the metal housing
• height no greater than distance the
gingiva and metal housing
5. Fit metal housing
6. Place adhesive, dry for 30 sec
7. Place resin
8. Let the patient bite moderately for 6-8
min
9. check occlusion
10. Remove excess resin
11. Polish
12. Fit to patient. Check support and
occlusion
