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 implant	Zygomatic implant
Type of implants	Single piece Implants is used. No screw loosening and no crestal bone loss.	Screw based implants used. 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
Anaesthesia	Local anaesthesia with or without sedation	General anaesthesia
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

When the patient requires fixed teeth on dental implants in upper jaw, then the options are:

»	Cantilever bridges: For example in All-on-4 or All-on-6 techniques, implants are placed in anterior regions only and as such 1^st molar crowns are placed as cantilevers and 2^nd molars are not replaced at all. Sometimes only 10 teeth are placed. Another disadvantage of cantilevers is that the permanent ceramic bridges are fixed after 3-6 months.

What are Tuberopterygoid implants

Pterygoid implants are implants located in 2^nd molar area of upper jaw. They allow the prosthetic rehabilitation on dental implants in upper jaw. The applied forces go to the pterygomaxillar buttress area allowing immediate loading of the implants.

Advantages of pterygoid implants

»	Eliminates the need of sinus grafting.
»	No cantilevers from front teeth or implants
»	Efficient chewing is possible as teeth upto second molars are replaced. In cantilevers and zygomatic implant cases or in all-on -4 and all – on – 6 techniques 2^nd molars are not replaced. If replaced then they are made as cantilevers which make the last implant weak and the bridge susceptible to fracture in the long run.
»	Bone in pterygoid area is cortical in nature, and hence very strong and rigid allowing Immediate loading with permanent crown in 3 days.
»	Single piece implants are used which are strong in comparision to conventional dental implants
»	All patients who want dental implants in upper jaw are good candidates as bone is always available in pterygoid area.
»	Flapless technique is used, as such patients have no swelling or bleeding and patients need not stop blood thinners, if they are taking any.
»	Lifetime warranty given as strong single piece implants are being used in strong cortical bone.
»	100% success rate.
