However, opinions may vary among clinicians in this perspective. The negative side effects of retraction with bone screws are lesser as compared to mini-implant retraction — like development of posterior openbite and anterior deepbite. Due to the very position in which bone screws are placed-the point of application of force is more parallel and close to the occlusal plane which reduces the chance of occlusal plane rotation so commonly associated with mini-implant supported retraction [Figure 7].
However, the height of the hook and the vector of force from the bone screw still determines the overall control on the occlusal plane. Difference in biomechanics of retraction between bone screws and mini-implants Click here to view With respect to arch form considerations — bone screw-supported retraction has serious implications. Since the force is applied from a more buccally positioned anchorage unit the chances of rolling in of molar is higher, which needs to be compensated with an expanded arch form or a torque in the wire whichever is suitable for the clinical situation.
Mini-screws due to their inter-radicular placement does not have such side effects [Figure 8]. Transverse considerations in biomechanics Biologic Limits of Distalization with Orthodontic Bone Screws In the maxillary arch — the limits of distalization follow the Rickett's criteria age-dependent and sagittal distance from the pterygoid vertical.
Ideally fully erupted third molars are to be removed to create space and aid in the distalization process. For un-erupted third molars placed below the cement-enamel junction of the 2nd molars in young individuals, distalization is possible without their extraction if the criterias are full filled, extractions are however indicated at a later date to prevent relapse.
In the mandibular arch — the limits of distalization is the proximity of the roots of the 2nd molar to the lingual cortical plate angle of Inflection [Figure 9]. For distalization in the mandibular arch almost invariably 3rd molar extraction is mandatory. Limits of mandibular distalization Complications and Success Rate of Bone Screws as Compared to Micro-Implants There are hardly any complications associated with the insertion process of bone screws except for minor bleeding.
Breakage of tip of the screw is never a problem if pure stainless steel good quality screws are used. The most common complication associated with bone screws are gingival overgrowth on the screw and early loosening of the screw. To avoid problems related to gingival overgrowth — oral hygiene maintenance is of utmost necessity. The incidence of gingival overgrowth is far less with screws having larger heads.
In case of early loosening of the screw— re-placement of the screw is advisable in a different site. As compared to micro-implants the stability and success rate of bone screws are far more superior-purely because of their larger dimension and placement sites having excellent quality of cortical bone.
