SINGAPORE: From 13 to 15 April, the International Dental Exhibition and Meeting (IDEM) 2018 Scientific Conference will be held for the tenth time. The event line-up includes papers by a large number of prominent speakers, among them Dr Christopher Ho, a lecturer in the graduate diploma in oral implants and postgraduate prosthodontic programmes at the University of Sydney in Australia. At IDEM, Ho will be giving a presentation titled “Additive approach to complex rehabilitation: Digital workflow meets the art and science of dentistry”.

“Additive dentistry can be used to solve patients’ complex dental problems while preserving their existing tooth structure, and more dentists should use it,” said Ho, who is also a visiting lecturer at King’s College London in the UK and faculty member of the Global Institute for Dental Education and Academy of Dental Excellence.

“In the past, we had to grind teeth down to provide room for crowns made of porcelain fused to metal. Now, we can just bond very thin layers of materials such as ceramic or nano-hybrid composite resin to the remaining tooth structure instead. This is healthier and a superior treatment option because when you remove tooth structure, you are removing the integrity of the tooth and weakening the tooth, and you might also cause inadvertent damage to the pulp in the tooth,” he explained.

Furthermore, such additive techniques help to preserve the tooth’s remaining enamel. “When you bond materials to enamel, you get a very predictable bond over the long term, which is good for patients,” Ho said. Recent advances in additive materials, such as nano-hybrids and new versions of lithium disilicates, have increased the strength and brought about excellent longevity and better aesthetics with a lustre and fluorescence similar to those of natural teeth.

According to Ho, additive dentistry is especially recommended for people whose teeth have been worn down by grinding or acid erosion caused by poor diet or diseases such as anorexia and bulimia. Dentists should be familiar with both direct and indirect additive restoration techniques and use them either singly or in combination depending on the patient’s needs.

Ho concluded, “All dentists should have these additive concepts in their back pocket and know when and how to use them.”
