Do submerged roots hinder orthodontic treatment or the use of implants?

INTRODUCTION: In clinical practice, submerged roots are found with high frequency, and their presence can change the planning of dental movements and implant placement. OBJECTIVES: To provide explanations of possible developments in the area involved, according to the evolutionary stage of the process, at the time of diagnosis. DISCUSSION: After atrophy of the periodontal ligament and epithelial remnants of Malassez, ankylosis of the bone with the submerged root occurs, and initiates a process of replacement resorption. Until this process reaches the most advanced stage, this area represents an increased "bone" density, and if some care is not taken, this can generate resorption problems in the tooth to be moved. Whereas implants can be placed, despite the presence of the submerged root, irrespective of the stage of evolution. CONCLUSION: It is natural for the onset of alveolodental ankylosis and tooth replacement resorption to occur in submerged roots, and its stage of evolution will be decisive in the approach to be adopted in clinical planning.
