Minimally Invasive Cosmetic Dentistry (MiCD) is gaining popularity in routine clinical practice as it aims to provide a holistic patient-centric treatment approach with a focus on preserving sound tooth structure.  Recent advances in composite resin technology have paved the way for dentists to further expand on the clinical applications of direct restorative materials to adopt a more conservative treatment plan while addressing the patients’ needs and meeting expectations.

The incorporation of an operative microscope in my routine clinical practice has helped revolutionize the standard of care provided to my patients. The magnification and increased visibility obtained with operative microscopes have pushed me to enhance my skills and achieve a higher level of aesthetics and function with direct restorations.

The clinical case shared below highlights, how the MiCD concept and treatment approach can be successfully adopted to create natural life-like restorations using the “ONE layering Technique” to create individualized smile enhancements based on the patient’s needs and desires. 

Patient case 

A 35-year-old male patient visited the clinic requesting a smile enhancement. As a MiCD clinical trainer before making a clinical diagnosis, I usually spend time getting to know my patient's personality, expectations, habits, and behaviour as this provides a deeper understanding to customize the most suitable treatment plan for the patient. This patient is a highly qualified dental technician with a demanding work schedule therefore his expectations were to rejuvenate his smile within a short period of time while preserving his natural tooth structure (less biological cost).

After performing a thorough intraoral examination and careful clinical evaluation, a history of diastema closure, discoloured composite fillings in both lateral incisors and one protruded central incisor was identified.  As the patient was well informed on dental procedures and possible restorative options he requested for modification of the central incisors to appear longer and more symmetrical with replacement of the old restoration on both lateral incisors.

In addition to obtaining all the patient information, clinical evaluation, analysis and treatment planning it is very important to understand the new advances in dental materials as direct restorative options have become more mainstream for a wider range of clinical applications today, enabling dentists like me to explore more conservative treatment approaches while meeting patient needs.

After checking the patient's occlusion we decided to proceed with direct composite veneers for the two centrals with 75% width to high ratio as the patient requested long centrals and replacement of the old composite fillings on both lateral incisors with the Shofu range of Beautifil bioactive composites containing the clinically proven benefits of its patented S-PRG filler technology.

Conclusion 

MiCD treatment concept and protocols are easy to understand and immediately adopt into clinical practice. As a MiCD clinical trainer, I  have been able to successfully incorporate this patient-centric conservative treatment approach routinely in my practice where we focus on the patient needs and evaluate all treatment options with minimal biological cost, select the most suitable restorative materials and obtain the patient's commitment to maintaining the restorations with good oral hygiene and regular recall visits. As clinicians, our aim is to help patients achieve their desired smile while preserving natural tooth structure taking into consideration time and the cost involved. 

The  Beautifil range of Shofu bioactive direct composites used in this clinical case helps to showcase that material selection plays an important role to help achieve predictable direct restorations with life-like aesthetics that meet the patient's expectations. The final step to achieving long-term success with direct restorations lies in the finishing and polishing protocol where attention to detail with a step-by-step approach helps to obtain enamel-like lustre optimising the aesthetic and functional outcomes.
