Abstract

When there is a lesion in a multi-rooted tooth, but only one root is infected, resective therapies are an effective treatment option for maintaining natural tooth structure. Hemisection may be the best line of action when a single root is decayed or periodontally compromised, but the other is intact. As precision and accuracy are paramount in ensuring the success of this procedure, this case explores the integration of 3D printing technology to create a patient-specific surgical guide that demonstrates excellent adaptability and precision during hemisection procedures. The integration of 3D printing technology in hemisection procedures, through the use of a customized surgical guide, offers a promising avenue for precision dentistry. This case report depicts a situation where the distal root of LR6 had extensive bone loss. Hemisection was planned for the tooth using 3D printing and a customized surgical guide to perform the procedure preserving the mesial root. CPD/Clinical Relevance: The use of patient-specific surgical guides, along with CBCT and 3D printing, can enhance the clinical outcome for hemisection.
