Orthodontics advances are increasing the comfort, alluring, and effectiveness of braces for the patients. Previously, most of the people feel nervousness in wearing old huge metal braces and dense bands on their teeth for so much time. But now people are enjoying their beautiful and healthy smiles within a shorter period of time more discreetly with advanced orthodontic treatments

TPA Orthodontics

TPA orthodontics is an orthodontic appliance that is used to control the position of molars and to an anchorage in the maxillary arch. Usually, a removable TPA appliance is used to place in the tubes on the palatal side of the molar bands.

TPA is first measured with the help of millimeter-scale or soft wires on the plaster models. After measuring the wire is bent to adapt to the palate. In total six bendings are required among which three are obligatory, and the other three are for bending the end of the TPA. This is held with the pliers to prevent the traumatizing of the palatal mucosa. It makes sure that it does not irritate the tongue.

Advantages of TPA

• Removing of molar bands and placing them in the plaster model is not required in this method. It considers the position of the palatal TPA tubes without this.


• The TPA is prepared individually for each tooth.

Complications of TPA

• It may cause anchorage loss.


• It increases the risk of root resorption.


• It has approximately 2% and 30% for breakage and cementation failure respectively.


• It can also cause palatal trauma due to the loop of TPA.

Nance Orthodontics

Nance appliance are brought up by Nance in 1947. It is a modified maxillary lingual arch which approximates the slope of the anterior palate without contacting the anterior teeth. These are used to restrict the rotation and movement of upper molars after the extraction of primary teeth.

Disadvantages of Nance

• It can cause deterioration of oral hygiene below the acrylic plate which leads to palate inflammation.


• Patient tolerance is very poor as compared to TPA.


• It includes pathology.


• It does not restore the function.


• It cannot prevent the extrusion of the opposing tooth.


• If the tooth anterior space is exfoliated then it has to be replaced immediately.

Advantages of Nance

• It is very simple and easy to construct.


• It moderates the chair time.


• It provides room for the eruption of the permanent tooth.


• It is very easy to clean.


• It is very affordable.
