Exploring Unique Dental Materials: An Expat Dentist’s Perspective
Discovering Dental Technology
Working as an expat dentist in Singapore has opened our eyes to the world of dental materials. Changes in dental materials continue to introduce options that are now used in day-to-day practice at Skye Dental. These materials influence how clinicians plan and deliver treatment, with each requiring appropriate assessment and use based on individual needs.
The journey through various dental materials has been particularly fascinating in Singapore’s multicultural environment. We’ve encountered patients from diverse backgrounds, each presenting unique challenges that require careful material selection.
Composite
The development of composite materials has introduced options that differ from earlier versions used in dental practice. Nano-hybrid composites are designed to support both functional and aesthetic needs, enabling restorations that can be matched closely to natural tooth structure. These materials use nanoparticles to help maintain surface smoothness and resistance to everyday wear, addressing previous concerns regarding longevity.
A notable feature of composites is their capacity to reflect and transmit light in a way that aligns with natural teeth. Their translucency and fluorescence can be selected according to individual clinical requirements, enabling restorations that integrate with the surrounding dentition.
Materials Used in Everyday Restorative Dentistry
A wide range of restorative materials is used in general dental practice, each selected according to the needs of the individual case. These materials differ in composition, handling characteristics, and suitability for specific clinical situations. Some are designed for direct placement in the mouth, while others are processed in a laboratory before being fitted.
Commonly used options include composite resins, ceramics, and various metal-based materials. Each type has its own indications, such as suitability for areas under higher chewing forces or situations where a closer match to natural tooth appearance is required. The choice of material depends on factors such as the location of the restoration, the amount of remaining tooth structure, and the patient’s overall oral health.
This approach allows clinicians to plan treatments that align with functional needs and the long-term maintenance of the tooth.
Ceramic Systems
Developments in ceramic materials have provided clinicians with a wider selection of options for different restorative situations. Lithium disilicate ceramics can be used for both front and back teeth and may be shaped using CAD/CAM processes to support an appropriate fit for each case.
Zirconia-based ceramics have also continued to develop, with newer types offering a range of translucency levels. Multi-layered zirconia blocks allow for restorations with gradual colour variation, reducing the need for multiple ceramic layers during fabrication.
Smart Materials and Ongoing Research
Shape memory alloys form another category of materials used in dentistry. These alloys can return to a set shape when exposed to certain temperatures, making them suitable for selected orthodontic and prosthetic applications.
Materials incorporating silver nanoparticles or quaternary ammonium compounds are currently being explored for their potential to reduce bacterial accumulation on restorative surfaces. These options aim to limit biofilm formation while maintaining necessary structural properties.
Continued Development
Our work at Skye Dental has shown that keeping up to date with material science helps inform clinical decision-making. Each material has its own indications, limitations, and handling requirements, and must be assessed carefully before use. Ongoing research in dental materials provides clinicians with new information that can support future treatment planning. Singapore’s focus on healthcare research allows access to a wide range of materials for evaluation and appropriate application.
