OrthoMTA Carrier provides unrestricted access to the canal orifice, allowing an accurate orthograde grafting procedure with MTA whilst avoiding the dispersion of the root grafting material in the oral cavity.
The use of MTA powder in orthograde grafting of the root canal was introduced by Dr Yoo (2009). To improve the prognosis for success of orthograde grafting with MTA, BioMTA concentrated on the development of orthograde root canal grafting materials.
The orthograde grafting techniques with OrthoMTA have resulted in a considerable improvement in the quality of orthograde root canal graftings and significantly improved the success rate statistics.
The apical 5mm preparation of the root canal is particularly important. This is because orthograde root canal grafting requires sufficient space for apical irrigation and apical plug formation without microleakage.
The success of orthograde root canal grafting depends to a very large extent on the quality of the orthograde obturation. OrthoMTA has superior sealing properties to any other materials.
The complete instrument set consists of a stainless steel applicator syringe (fig.1) with a bayonet catch for the disposable cannulas (needles) and luer lock connector. The small diameter of the application needles means that the root canal grafting can be applied directly into the root canal orifice.
