And why is crucially necessary.
As all implant placing dentist know the implant(fixture) placed in the patient’s mouth needs to its heads(abutments) in order to place the dental restorations.
How can implant abutments that are made outside of the patient’s mouth be placed accurately into the implant fixture that are placed in the mouth as finding the correct angle and position takes great amount of effort, time and delicacy?
Verification Jig is the solution.
Hexagon Shaped Abutments
The most of the connecting hole between abutments and implant systems with the latest technology is shaped hexagon which means that there are only 6 correct angle to place the abutment in to the fixture (implant). Furthermore, there is only one angle among six leads to the right passage.
Finding the one out the six angles is not the only complications in placing the abutment accurately to the fixture for each and every shape and angle of the abutment is not only irregular and has own attributes due to the bone graft and the space shape and sizes (every tooth has its own unique attributes) but also is very tiny, thus each case needs custom attention and attentiveness especially if there are more than two implant restorations are prepared. Finding the accurate positions of each abutments requires the extremely tedious and effort consuming care
Here are the 6 photos, showing how the abutment can be placed at six different angles into the fixture(lab analog) however only one (5th) out of six is the correct position for the abutment placement.
Here are photos of placing the implant zirconia crown onto the correctly positioned abutment.
So in order to avoid trying all six angles before finally placing the abutment in the correct direction and to have the procedure easier and faster yet effectively, the verification jig comes in the picture.
Here is the Wikipedia Definition of Jig

As its definition, in dentistry Jig is a supporting and guiding tool that is custom made to help placing the abutment accurately into the implant system in patient’s mouth.
The looks of the jigs vary by the technicians who crafts them, however the mechanism behind its structure and functionality of it are all same, only the practicality can be differ by each dentist,
The cute looking pink Jig shown below in the photo is the Maestro Art style Verification jig, which the most doctors prefer over other designs due to its simplicity and user-friendly design.
Maestro Art style Jig comes attached with little wings with the holes on both sides or one side depending on the restoration type, which are assigned to precisely set on highest spot of the adjacent teeth to not only help placing the jig in the correct position easily and conspicuously but also to fixate the sitting of the jig, minimizing any tilt or shaking to prevent any possible abutment and screw passage deviation. The numbers written on the jig are the tooth numbers which should be placed accordingly in the mouth of the patient and are used for a double confirmation for ensuring the correct placement of the jig.
