In cosmetic dentistry, the angle of tooth preparation is a crucial element that determines the long-term success of restorations. A carefully calculated angle ensures that veneers or crowns fit securely and seamlessly, without compromising the natural tooth structure.
When this step is performed with accuracy, it enhances both the durability of the restoration & the harmony of the smile’s appearance. It is a meticulous process that calls for expertise & attention to detail, forming the very foundation for achieving natural, lasting and beautiful results in cosmetic dentistry.
The axial inclination
Each front tooth tilts slightly towards the midline, increasing from central to canine. Teeth that are all vertical look artificial; too much tilt looks crowded.
The line angles and embrasures
Where the flat face of a tooth turns to its side decides whether it looks wide or narrow; the small triangular spaces between edges decide whether the smile looks young or worn.
The smile arc
The angle of the incisal edges relative to the lower lip. Following the lip makes the smile look natural and youthful; a flat line ages it. Measured on video, not guessed.
