Zygomatic implants compared with Tubero pterigoid Implants

Tuberopterygoid Implants Vs Zygomatic implants

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
