Maintain Access Strip Technique (MAST) crown: a novel technique to stabilize anterior teeth while maintaining pulp canal access W Donovan A Crummey G Wright Dental Update 2024 50:3, 707-709.
The management of an anterior tooth that has undergone breakdown, either due to trauma or failure of previous restorations, poses a challenge for clinicians to restore in situations where endodontic treatment is also necessary. The novel technique described in this Technique Tip: Maintain Access Strip Technique (MAST) crown, allows clinicians to effectively restore function and aesthetic form to an anterior tooth, while maintaining ease of access to the pulpal anatomy for future endodontic treatment. The approach uses clear strip crowns to reproduce coronal structure and anatomy with gutta percha cones for canal projection to maintain a path to the endodontic space.
CPD/Clinical Relevance: The MAST crown technique facilitates stabilization of traumatized or broken teeth and maintain ease of access to the root canal.
Article
The Maintain Access Strip Technique (MAST) aims to restore and stabilize anterior teeth that have suffered significant enamel–dentine–pulp trauma, or require stabilization during root canal treatment following failure of existing coronal restorations or extensive dental caries. The methods and protocol for the technique are described in detail and highlight this novel and time saving technique for maintaining patient function and successful endodontic principles.
The anterior tooth that has suffered significant trauma often requires endodontic treatment for future maintenance and function.1 For patients, such trauma can be physically uncomfortable and both functionally and aesthetically unpleasant. Studies have shown that dental trauma can affect the quality of life of both children2 and adults.3 Therefore, the goal of a clinician managing such an initial presentation of trauma in an emergency setting should be to restore function, appearance and ensure the patient remains asymptomatic prior to long-term definitive treatment.
