Orthodontic Crown Lengthening

Orthodontic crown lengthening has the same biologic basis as traditional crown lengthening, and that is getting the margin of the restoration 3mm away from the level of the bone. Whereas surgical crown lengthening works well from a functional and biological standpoint, if done in the upper front teeth it can sometimes result in an un-esthetic appearance of the gum tissue.

Orthodontic crown lengthening is a method of achieving the biological crown lengthening required while still maintaining the esthetics that are so important in the front teeth.

How does it work?
Orthodontic crown lengthening takes advantage of dental anatomy and uses it to your advantage. There are fibers, called supra-crestal fibers. These supra-crestal fibers go from the tooth to the top of the bone. Orthodontic brackets (braces) are put on the tooth to be lengthened, as well as on one tooth on each side. With the braces we orthodontically erupt the tooth. If the supra-crestal fibers are left intact then as the tooth erupts these fibers will “pull” the bone and gum tissue with it. This would not give you any lengthening of the crown. If, however, the supra-crestal fibers are cut as the tooth is erupted, the tooth will erupt, the bone will stay put, the crown will be lengthened, and the esthetics will have been preserved. Generally it takes 2-3 weeks of active eruption followed by 3 months of stabilization before you can get your final restoration.

Due to the severity of my dental needs, my regular dentist referred me to Dr. Engen’s office. Being referred to a periodontal specialist is not something I would wish upon anyone, and it was difficult going to another dentist. However, from the minute I entered their office I was greeted by professional, friendly staff members who acknowledged me with a warm smile and a pleasant, cheerful welcome. The doctors and hygienists demonstrated a high level of expertise and technical competency by effectively communicating the options available to address my dental needs. Each and every staff member I encountered, from the receptionist, to the doctors are extremely dedicated to creating a long term relationship with each one of their patients, including taking the time to educate each patient about oral hygiene. The staff at your office works harmoniously, cooperatively and effectively as a team to make your time with them as productive as possible. I would highly recommend this office to anyone seeking resolution to any dental issues and be assured you will be pleasantly surprised with your time with them.

He was very friendly, and made me feel comfortable about what was going to happen and the steps we needed to take.
