Intrusão do primeiro molar permanente com ancoragem esquelética: revisão de literatura

Abstract

INTRODUCTION: Among the therapeutic approaches for the treatment of permanent molar intrusion, is the retraction of the upper teeth. The use of mini-implants, especially extra- alveolar ones, has stood out due to its obtaining absolute anchorage for the retraction mechanics. OBJECTIVES: To perform a literature review about the recovery of prosthetic space with the intrusion of the first molar with mini- implants. METHODOLOGY: To obtain this bibliographic review, searches were carried out in the following databases: Pubmed, Medline, Scielo and Google Scholar, published between 2004 and 2020. The keywords used for the research were: "Molar intrusion", "Mini-implants", "skeletal anchorage", and its analogues in English: Dental intrusion, mini-implants, skeletal anchorage. RESULTS: It is expected that the results of this bibliographic review can contribute in a relevant way to the individual's well-being and oral health, through the success of molar intrusion with orthodontic mechanics anchored in mini-implants and, consequently, recovery of the prosthetic space for rehabilitation. FINAL CONSIDERATIONS: The use of titanium mini- implants to obtain a skeletal anchorage brought new perspectives for the treatments, allowing to employ a simpler orthodontic mechanics, requiring, however, knowledge of biomechanics for its correct application. It is suggested, then, replacement of the lost teeth for the adequacy of the oral environment, so that the adequate and balanced occlusion occurs, thus preventing the recurrence of the obtained movement.
