A balanced bite is the key to long term success and satisfaction to any dental treatment, from cosmetic and oral reconstruction (click), periodontal, or implants. Yet it is so often ignored. Without a balanced bite, damage (click) will continue to the oral structures and expensive dental treatment. Teeth will continue to wear, crack and move; implants will fail, porcelain veneers, crown and bridges will break or be rejected, and periodontal disease will progress.
Most of you have experienced a dentist adjusting a filling or crown to make it fit into your bite. This is of course necessarily, but limited in scope. Rarely is the entire bite or occlusion balanced in a comprehensive way which takes into consideration all the teeth, the jaw muscles and the jaw joints or TMJ. A balanced bite should achieve harmony between the teeth, the jaw muscles and the jaw joints or TMJs.
1) A balanced bite starts with the lower jaw properly seated in the jaw joints or TMJs.
The bite or occlusion dictates the position of the lower jaw in the jaw joint. With the above bite, the lower jaw is in a bad position in the jaw joint or TMJ (green lines do not line up). Most people have jaws that are positioned like this. This is unstable, and causes many dental problems.
With the above bite, the lower jaw is in a good position in the jaw joint or TMJ. This is stable and conducive to long term health.
2) Along with maintaining the proper position of the lower jaw in the jaw joint or TMJ, a balanced bite requires that all the teeth initially contact evenly when biting to reduce stress.
3) In addition to maintaining balance in a static bite position (above), the teeth need to allow proper jaw function when they slide over each other during movement. Watch the 2 brief videos below to understand this concept.
