Dr. Melvin Sia has adopted the modern concept of minimally invasive cosmetic dentistry into his daily practice. He has made it his mission to provide dental treatments that restore patients’ smiles and function without compromising healthy tooth structure.


With the increasing demand for cosmetic dental procedures, modern dentistry has emphasized the need for treatment modalities that do not compromise the patient's long-term oral health while fulfilling their desire for a beautiful smile.

For doctors like Dr. Melvin Sia, a general dentist specializing in aesthetic and restorative dentistry, the concept of minimally invasive treatments has become his standard protocol.

From a child who was afraid of dentists, he now runs his dental practice in Petaling Jaya, Malaysia, to create healthy and life-changing smiles.



Dr. Sia always wanted to take up a profession that could change a person's life. He originally wanted to be a doctor, but then decided to become a dentist because he enjoyed the work-life balance.

With a penchant for aesthetic and restorative dentistry, he continues to educate himself by attending numerous continuing education courses, taking time to practice his carvings on the typodont, and constantly reviewing his work.

He strives for excellence and is motivated to find ways to improve further to provide quality treatments to his patients. Dr. Sia is fascinated by the complexity of tooth morphology and the uniqueness of each tooth.

While it is a challenge, when he can successfully recreate it, it gives him a great sense of accomplishment. But to be successful in practice, Dr. Sia stresses that he must also have good communication skills.

"If you communicate well with your patients, they can better understand their dental problems and how the treatment plan you propose can help them," he explains.

It pays to be a good listener to be able to address patients' complaints and expectations. Feeling his patients' joy after treatment and seeing their brand new smile boost their confidence is the best part of his job.



Dr. Sia practices Minimally Invasive Cosmetic Dentistry (MiCD) to advocate a patient-centered restorative approach with the motto "Do no harm".

In an article by Dr. Sushil Koirala, founder of the global MiCD network, MiCD was defined as “a holistic approach that explores the smile defects and aesthetic desires of a patient at an early stage and treats them using the least intervention options in diagnosis and treatment technology by considering the psychology, health, function, and aesthetics of the patient."

In this modality, Dr. Sia divides his treatment protocol into three phases:

  • Phase I - understand: identify the problem through a detailed dental examination and establish a well-thought-out treatment plan.
  • Phase II - achieve: carry out the planned treatment, either rejuvenate, restore or rehabilitate
  • Phase III - keep in touch: continue to follow up with patients and call them in for follow-up; re-evaluate and repair as needed

He also applies four levels of intervention: non-invasive, micro-invasive, minimally invasive, and invasive.

"I always begin with a non-invasive approach, which is education. It’s part of our job to educate our patients on proper oral health care and maintenance,” he explained.

Micro invasive procedures in his aesthetic work include whitening and resin infiltration, while minimally invasive treatment includes restorative work with composite and less or minimally prepared veneers.

In addition to his hard-earned skills, this novel treatment approach ensures the quality of Dr. Sia's work by complementing it with reliable materials and technologies.

He said, "I can't work without my loupes and my microscope. The microscope allows me to see better not only during root canal treatment but also during my direct and indirect restorative work. It allows my preparations to be more precise so I can preserve more tooth structure."

His current favorite instrument set is the LM Arte composite instrument set, which he considers essential in his restorations. His other essential instruments include Stick Resins from GC and Rubber Dam from Sanctuary. He also uses Shofu Beautifil II LS, Tokuyama Palfique Asteria, and Micerium Ena Hri.

In addition, his clinic is equipped with a cone-beam computed tomography (CBCT) scanner for a more accurate diagnosis.

Plans are already underway to digitize his practice soon, as he believes intraoral scanners and in-house milling machines can further benefit his patients.
