Controlling anchorage is one of the foremost necessary aspects of treatment. Moderate anchorage is comparatively simple to manage with the use of some intraoral appliances and biomechanical procedures. On the opposite hand, cases that need the most anchorage need extraoral support to strengthen the anchorage. In some instances, 100 percent anchorage has got to be maintained, such an anchorage may be termed as absolute anchorage. It's tough and not possible to get absolute anchorage by using typical ways like extraoral force application. In this case report, we describe the treatment of Open bite by using the support of Zygomatic plates and Spurs anteriorly placed with the combination of posterior bite blocks.A 20-year-old female reported to our department of orthodontics with the chief complaint of anteriorly placed upper front teeth. There was no relevant medical history; she was having tongue thrusting habit, acute nasolabial angle and incompetent lips. Overjet of 12mm and anterior skeletal open bite from canine to canine of 5mm was present associated with anterior tongue thrusting habit, and constricted upper arch. The molar relation was end-on on the right side and class II on left side. Canine relation is end-on, on both the side. Growth pattern is vertical. Upper arch is well aligned with constriction in premolar region; lower arch has crowding of 6 mm. The treatment plan was selected as alignment of the teeth with fixed mechanotherapy and impaction of the maxillary posteriors using zygomatic anchorage with posterior bite block and spurs soldered to the anterior part of the appliance. The sutures were removed after 7 days, the appliance was into the patient’s mouth and secured with a power chain to the hooks of the appliance and the hook of zygomatic implant, 400gms of force was applied on both the sides.
