This anchor is designed for placement from a palatal approach. It has two thread sizes as described in the Mesial anchor above. As with the Mesial Anchor it has tissue -cutting threads in the base (head). These threads are longer than those in the Mesial Anchor to accommodate the thicker palatal tissue, which ranges from 2 to 4 mm in thickness. This taller base (head) allows for more tissue threads, and positions the ligature attachment point proud of the tissue for clinician access, and patient comfort.
This anchor is placed in the infrazygomatic process of the maxillary bone. It has a tapered thread that reaches a maximum of 2.5mm in diameter at its bone contact surface. The bone in this infrazygomatic process is denser than in the other areas of the mouth described above. This anchor can accommodate force exceeding 350 grams. This anchor also has a four mm base, as do the other designs. A spindle shaped area extending from the base to the head of the anchor accommodates soft tissue that often will be present in this area of the mouth. This spindle shaped base (head) locates the attachment point of the infrazygomatic anchor proud of the tissue keeping the anchor visible throughout treatment so the clinician can have unrestricted access to change attachments
This anchor is specifically designed for use in the anterior portion of the mouth where the incisors are located and the roots are close together. This anchor is used, primarily, when placing an anchor in between the roots of the teeth, therefore, the thread diameter is only 1.5 mm. The Incisal Anchor utilizes a single thread size to maximize root clearance.
This anchor is placed mesial, (anterior) to the upper and lower molars. There are two thread sizes on the shaft of the anchor. The smaller diameter thread, located distal to the base (head) of the anchor, has a self-tapping starter point, and cancellous threads to facilitate installation. The larger thread size, located adjacent to the head of the anchor, threads into the cortical bone, thus giving it a more stable retention. This anchor also has tissue-cutting threads above the base that will negate the clinician from having to remove a plug of tissue. This allows the anchor base to be in contact with the surface of cortical bone, transferring the force from inside the bone to the surface of cortical bone.
