Background:
Oral and maxillofacial tissue defects resulting from factors such as trauma or infection, can significantly impact both facial function and aesthetics. Additionally, the complex anatomical structure of the face often increases the difficulty of treatment. With the advantages of controlled release, targeted delivery, and enhanced mechanical properties, injectable hydrogels have been investigated for the treatment of oral and maxillofacial diseases. In the field of regeneration, injectable hydrogels have a structure similar to the extracellular matrix (ECM) and are biocompatible, which can be used as scaffolds for tissue regeneration.
Objective:
This review aims to summarize the literature on the current status and limitations of injectable hydrogels in the field of oral tissue regeneration.
Methods:
We searched Pubmed and Web of Science databases to find and summarize the articles on the application of injectable hydrogels in tissue regeneration.
Conclusions:
This review focuses on the current status and limitations of injectable hydrogels in the field of tissue regeneration (periodontal tissue, dentin-pulp complex, bone and cartilage, salivary gland regeneration, and mucosal repair). Although fully studied in animal models, there are still challenges in clinical transformation of injectable hydrogels in promoting tissue regeneration.
