The term “Bonding" is reminiscent of the term “Bondo” which is the cheap way of fixing things. "Bonding" and "Bondo" have given composite a bad name.
This patchwork style bonding on the central incisors (pictured above) demonstrates all the pitfalls of traditional methods of "bonding" composite. Note the excess translucency & small holes full of brown stain.
Frequently, “Cosmetic Dentistry Experts” tell the public that bonding is inferior to porcelain veneers. While porcelain veneers are indeed beautiful restorations, the malignment of composite as a material is based on a flawed method of application, lack of training, and a dearth of proper engineering principles that sooner or later looks like poor asphalt patchwork. The Bioclear approach is not bonding. It is injection overmolding. Instead of just patching the tooth, the Bioclear Matrix and method allows the entire tooth to be overmolded with variable thickness composite. Why perform patchwork when you can routinely pave the whole street? Properly done, it is superior to porcelain for both black triangles and young post-orthodontic patients because bioclear avoids the aggressive tooth removal required for veneers in teeth with this anatomy.
Injection Overmolding for Management of "Black Triangles"
The concept of the BioClear Method involves several distinct features: an anatomic matrix system that mimics the contours of real teeth, Biofilm blasting (removal), heated composite, injection overmolding with an infinity edge, and glass-like polishing. Rather than out-dated "patchwork style" of filling, teeth are injection overmolded, meaning that the tooth is covered and protected by the material.
