Molar intrusion using mini-implants: a literature review

Abstract

The identification and treatment of patients presenting posterior tooth loss are common occurrences in orthodontic practice, particularly in adults. The main cause for tooth extrusion involvement is the premature loss of the tooth, along with other factors such as deleterious habits, nail biting, and bruxism. The primary factor necessitating molar intrusion is the loss of antagonistic teeth or, in cases of excessive anterior verticality, resulting in the extrusion of posterior teeth. Compared to anterior tooth intrusion, posterior intrusion becomes more challenging due to the larger root volume of molars and premolars. The purpose of this study is to conduct a literature review addressing the techniques associated with molar intrusion using mini-implants. The aim is to deepen the orthodontist's understanding of this treatment, emphasizing its relevance in the clinical practice of these professionals. The use of molars with mini-implants is a well-established technique in the literature with many therapeutic possibilities. Mini-implants enable the establishment of an effective anchorage system with significant clinical applicability, assisting the orthodontist in molar intrusion, a condition commonly encountered in clinical practice, especially in adult patients.
