ANALYZING DEVICES AND METHODS FOR ASSESSING THE PRIMARY STABILITY OF ORTHODONTIC MINI-IMPLANTS

Abstract

When disruptions occur in the mechanisms regulating the eruption of lower jaw molars, it becomes necessary to artificially extract and reposition them within the dentition. Various treatment methods are employed for this purpose, with the primary approach involving traction fixed to teeth or other anchorage elements and bone supports. Skeletal support is preferred to minimize resistance from orthodontic appliances when applying force to the patient's teeth. The utilization of mini-implants for anchorage demonstrates a relatively high success rate, though instances of failures and complications are not unheard of. Potential issues such as stability loss and mini-implant displacement may necessitate relocation or adjustments to treatment strategies, posing challenges for both practitioners and patients. Unlike dental implants, where secondary stability often dictates treatment success, primary stability holds paramount importance for orthodontic mini-implants. Investigating primary stability parameters can significantly impact treatment strategy selection and orthodontic mini-implant loading timelines. Focusing solely on mini-implant torque during placement is inadequate, as it fails to comprehensively gauge real stability. Moreover, the available range of torque indicators for orthodontic mini-implant placement is limited, typically ranging from 5ncm to 10 ncm. Furthermore, the selection of specialized devices for measuring primary stability is limited and necessitates meticulous evaluation.
