The interrelationship between prosthodontics and periodontics is crucial in achieving optimal oral health and function. Prosthodontics deals with replacing missing teeth and restoring oral function, while periodontics focuses on the health of the gums and supporting structures of the teeth. Together, they collaborate to ensure the success of the dental prosthetic treatments, considering factors like gum health, bone support, and stability of dental implants. This book highlights this collaboration that aims to achieve long-term success and harmony between the prosthesis and the oral structures.
