Zygomatic implants compared with Tubero pterigoid Implants

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
