Ceramic brackets are widely used in orthodontic treatment because their color is closer to natural teeth. Compared with metal brackets, ceramic brackets offer a more discreet appearance and are often preferred by patients who care about aesthetics during treatment.
However, ceramic brackets should not be selected by appearance alone. For orthodontists, clinics, and distributors, important factors also include material, bonding stability, friction control, bracket strength, edge comfort, and cost-performance.
Sino Ortho offers two main traditional ceramic bracket series: Song Series and Bright Series. Song Series includes Song I and Song II, focusing on natural aesthetics, stable bonding, and cost-performance. Bright Series adds a metal slot insert to the ceramic bracket body, making it a better option when lower friction is required.
Both series are made with polycrystalline alumina ceramic material, a commonly used material for aesthetic orthodontic brackets. In the current product range, the key differences between Song I, Song II, and Bright Series are mainly found in the bonding base design and slot structure. Modern ceramic bracket systems from major orthodontic brands also emphasize polycrystalline alumina ceramic technology, smooth rounded surfaces, low-profile design, and patient comfort.
Song I is a classic traditional ceramic bracket in the Sino Ortho Song Series. It is made from polycrystalline alumina ceramic material and uses a traditional three-groove bonding base.
Song I has been in production for more than 20 years. With long-term manufacturing experience and market application, it has become a mature, stable, and cost-effective ceramic bracket option.
The three-groove bonding base provides reliable mechanical retention. According to Sino Ortho product data, Song I offers approximately 35–40+ N bonding strength. For routine aesthetic orthodontic cases, it provides a practical balance between appearance, bonding performance, and cost.
Song II is the upgraded option in the Sino Ortho Song Series. Compared with Song I, the main improvement is the mesh-style bonding base.
The base of Song II uses multiple raised bonding points. This structure increases the contact area between the bracket base and adhesive, helping improve bonding stability. According to Sino Ortho product data, Song II offers approximately 40–50+ N bonding strength, which is more than 10% higher than the traditional three-groove base design.
For Song II, the key product advantages should focus on the mesh bonding base, smoother edge transition, and low-irritation design. These features help reduce soft tissue irritation and improve patient comfort during wear.
A smooth bracket surface and rounded corners are also common design directions in modern ceramic bracket products. For example, 3M highlights smooth surfaces and rounded corners to minimize soft tissue contact and abrasion in its ceramic bracket design.
Bright Series is another traditional ceramic bracket series from Sino Ortho. Its ceramic body is also made from polycrystalline alumina material, but the slot area is designed with a metal insert.
Compared with Song Series, the most important feature of Bright Series is the metal slot design. The metal slot helps improve archwire sliding performance and reduces friction between the archwire and the bracket slot.
Traditional ceramic slots usually generate higher friction than metal slots. By adding a metal insert, Bright Series helps solve this limitation. According to Sino Ortho product data, Bright Series can reduce friction by more than 70%, making its sliding performance closer to that of standard metal brackets, such as Tang Series.
The trade-off is appearance. Because the metal slot is visible, Bright Series cannot look as fully tooth-colored as Song Series. For cases where natural aesthetics are the main priority, Song Series offers a cleaner ceramic appearance. For cases where lower friction and smoother sliding mechanics are more important, Bright Series offers stronger mechanical advantages.
