We are thrilled to have Dr. Ravindra Nanda as our guest on the podcast. During our conversation, Dr. Nanda will explore groundbreaking advancements in the field of aligner orthodontics. He will provide insights into the innovative technology enabling orthodontists to sustainably produce aligners in their offices. While minimal training is needed, the mechanics behind this process are remarkably straightforward. It's never been a better time to be an orthodontist.    IN THIS EPISODE: [04:32] Dr. Leon and Dr. Ravindra reminisce over their days at university and changes between now and then.  [06:19] Dr. Ravinda shares how he got involved with Graphy and how the process works.  [11:25] Dr. Ravinda discusses the cost of the aligners and functionality and shares the benefits to the patient.  [17:05] Treatment can accelerate the therapy and affect the impact on the environment.  [23:02] A listener asks a question of Dr. Ravinda regarding the mechanics of printing an aligner.  [27:32] Dr. Ravinda discusses the downside of the process.    KEY TAKEAWAYS:  Graphy produces aligners with shape memory. Graphy can print aligners in 32 minutes. A benefit of Graphy aligners is that you don’t need as many attachments to the teeth.    RESOURCE LINKS People + Practice  - Website Dr. Ravindra Nanda - Facebook Dr. Ravindra Nanda - Instagram   BIOGRAPHY:  Dr. Ravindra Nanda is at present UConn Alumni Endowed Chair, and Professor and Head of the Department of Craniofacial Sciences and Chair of division of Orthodontics, University of Connecticut, Farmington, Connecticut, U.S.A.

Then you take the resin and place it in the tray, plug in your software. This plate will come down where the resin is, and it moves up, and in about 32 minutes, you will have six to ten aligners.” Dr. Ravindra Nanda “Say you have 5 million patients using models. That means at least 150 million models are being thrown somewhere in the environment. So we are polluting like crazy. The aligner would be the only pollution. We are going to tell our patients how to get rid of those aligners because nobody talks about it, you give the aligners, you forget about them.” Dr. Ravindra Nanda
