Biomechanical modifications made to accommodate orthodontic treatment of adult dentitions are generally minor and adhere to the basic laws of physics as they apply to all orthodontic tooth movement. Some adult presentations necessitate changes in treatment strategy from what would otherwise be employed in adolescent patients to achieve similar goals. In other cases, objective themselves may need to be modified because of a lack of growth potential, constraints of treatment mandated by the patient, or the presence of multiple missing or compromised teeth. The possibilities and limitations of orthodontic and dentofacial orthopedic treatment for adults are usually easier to define before beginning therapy than with adolescent patients because the unknown contribution that growth will make has already been discounted. By planning treatment and mechanotherapy taking into account the individual circumstances that may affect the patient's biological response to treatment, realistic goals of orthodontics can be mutually recognized and agreed on by both the provider and the patient before therapy is initiated.
为适应成人牙列的正畸治疗而进行的生物力学改变通常较小，并遵循适用于所有正畸牙齿移动的基本物理定律。一些成人病例需要改变治疗策略，与青少年患者相比，以实现类似的目标。在其他情况下，由于缺乏生长潜力、患者规定的治疗限制或存在多颗缺失或受损牙齿，目标本身可能需要调整。与青少年患者相比，成人正畸和正颌正畸治疗的可能性和局限性在开始治疗前通常更容易确定，因为生长所起的未知作用已经被排除。通过考虑可能影响患者对治疗的生物学反应的个体情况来规划治疗和机械疗法，正畸的现实目标可以在治疗开始前由提供者和患者共同认可并达成一致。
