BOI Implants (No more sinus lift)


Basal osteointegrated implants are shortly called as BOI or Basal Implants. Because of its unique disc shape this is also known as Disc implants or Blade Implants.

There are three varieties of Basal Implants available in market:


Basal Implants

Basal Implants


These Implants crosses the middle soft bone and taking support from Hard Peripheral bone known as cortical bone. It takes anchorage from minimum three cortical bones so the strength and stability is unmatchable.

These Implants are designed in such a way that this does not require much of bone height so these Implants can be done in compromised bone conditions like:

  1. Atrophic maxilla or mandible
  2. Low level sinus areas
  3. Mandibular canal present superiorly

Specialties OF BOI


For some patients the mandibular canal can be present at the crustal level where no other implant system can be done without bone grafting

But the advance basal implant’s canal bypassing technique allows us to place

The disc below the canal and provides implant supported teeth without bone grafting.

  Trance sinus placement of BOI

Since these implants are resistance to infection. It can be placed inside the sinus. Which will get the stability from both end on sinus wall.


Basal Implants Better Than Zygomatic Implants

Zygoma Implants are more invasive and less predictable whereas the basal Implants are less

Invasive and more predictable. The difference between Basal Implants and Zygomatic Implants are

Explained below in the table

Basal Implants Vs. Zygomatic implants

 The advantage of basal implants over zygomatic implants

  Basal 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
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 6-8 for upper jaw. 8 -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
