There are two types of taps in the dental field. The first is the bone tap. This is a device used to create a threaded channel in bone for a fixation screw or, prior to the insertion of a dental implant, into an osteotomy. A bone tap may be used to prepare the bone for the implant required for a prosthesis. The second type is the metal tap. This is an instrument made of a hard metal used for rethreading damaged internal threads of a dental implant. The type of tap device required will depend on the specific procedure. Since there are a variety of tap dental devices that can be used to help place or fix dental implants, research may be needed prior to purchase. Tap dental appliance reviews may help in the selection of the correct device by using the tap appliance dental code. Appliance parts may also be researched to see which are best suited for the necessary procedures.
