Tuberopterygoid Implants Vs Zygomatic
implants
 |
| Tubero pterigiod screw |
 |
| Zygomatic screw |
If you have been told that there is less bone in your upper
jaw for dental implants, do not worry. The best solution for cases with severe
bone resorption in upper jaw is pterygoid implant. Pterygoid implants are
replacing zygomatic implants as the best solution for patients requiring dental
implants for upper jaw. Such patients were going for sinus lift or bone grafts
as per old techniques. In a single procedure we place pterygoid implant and
place the permanent crown in 3 days. As we use single piece implants the procedure
is flapless and done under local anaesthesia.

Tuberopterygoid Implants
|
Zygomatic implants
|
|
Type
of implants
|
Single
piece Implants is used
|
Screw
based implants used
|
|
Screw
loosening
|
No
screw loosening and no crestal bone loss
|
Screw
loosening is a problem
|
|
Cantilevers
|
No
cantilevers placed
|
Molars
if given are placed as cantilevers, which decrease the life of the bridge and
cause screw loosening on the implant.
|
|
Criteria
|
No
contraindications
|
Symptom
free and pathologically free sinus
|
|
Relative
risk of failure
|
Since
sinus is not involved, no risk of sinusitis
|
Risk
of sinus infection
|
|
Permanent
bridge
|
Permanent
ceramic bridge on 3rd day of implant placement, as the implant engages hard
cortical bone
|
Acrylic/plastic
for first 4 months. Then cantilever permanent ceramic bridge given after 4
months.
|
|
CT
scan
|
Not
needed.
|
Compulsorily
needed
|
|
Surgical
guide
|
Not
needed
|
Compulsorily
needed
|
|
Anesthesia
|
Local
anesthesia with or without sedation
|
General
anesthesia
|
|
Cost
of implant
|
Being
regular sized single piece implant it is relatively cheap.
|
Zygomatic
implants are very long manufactured specifically for the purpose, hence very
expensive. Cost of the technique is more as CT scan and surgical guide is
used.
|
|
No
of implants for full upper jaw
|
8-10
for upper jaw
|
6
-10 for upper jaw
|
|
No
of teeth
|
14
teeth are given
Teeth
replaced till second molar
|
10
teeth or 12 teeth given. 2nd molar is not given
|
|
No
of trips
|
One
trip, as permanent ceramic crown or bridge is placed in 3 days
|
Two
trips. Permanent teeth fixed after 3 months of implant placement
|
|
Warranty
|
Lifetime
warranty on implant
|
No
warranty
