Dental Diode Lasers (DDLs) in Orthodontics

The laser was first postulated by Albert Einstein in 1916. He suggested that portions of the electromagnetic field could be stimulated, thus producing amplified light. Thus, the acronym LASER stands for Light Amplification by Stimulated Emission of Radiation. Various scientists have brought this technology forward to the point where dental applications were envisioned, and first tested in 1964. Since then, tremendous advances have occurred, and we are now seeing lasers in dentistry for both hard and soft tissue applications.

Today, the soft tissue laser has been universally accepted as a tremendous adjunct to soft tissue therapies, offering an extremely precise, pain-free method for manipulating oral tissues. Diode lasers are finding their way into today’s top orthodontic practices; helping doctors manage common soft tissue problems associated with patients in braces, like through routine-

  • Laser-facilitated access for bracket placement
  • Gingivectomy - to improve access for oral hygiene
  • Esthetic gingival recontouring - following the removal of braces
  • Exposure of impacted or unerupted teeth
  • Hemostasis - to create a dry field for bonding braces
  • Operculectomy
  • Exposure of TADs (temporary orthodontic anchorage devices)

A variety of dental diode lasers (DDLs) are available to orthodontists. Current DDLs operate in three wavelengths: 810, 940, and 980 nanometers (nm), and each has different effects on soft tissue. Table 2 shows these wavelengths tendencies for absorption in three compounds: hemoglobin, oxyhemoglobin, and water. As Table 2 depicts, the 940 nm diode laser accounts for the highest overall absorption by hemoglobin, oxyhemoglobin, and water, making it highly effective for both clean surgical incisions (low carbonization) and excellent hemostasis; for common soft-tissue laser procedures in orthodontics, the 940 nm diode dental laser works best.

Table 2

All current DDLs provide laser energy in both Continuous Wave (CW) and Pulsed (P) modes. Uninterrupted continuous wave laser energy does not allow for thermal relaxation of the tissue, while pulsed modes allow for thermal recovery (cooling) between energy pulses

Pulse-mode lasers are necessary to deliver a comfortable surgical and post-surgical experience for patients; patients treated with selectable-pulse-mode lasers regularly report no discomfort with soft tissue laser procedures, since there is little-to-no evidence of thermal damage when performing soft tissue procedures with this technology. Most soft tissue laser procedures can be performed with only topical anesthesia. When a topical anesthetic is inadequate, a local anesthetic may be needed, but this is rarely necessary.

Amanda R., a sophomore in high school, required a gingivectomy for gum tissue overgrowth due to poor oral hygiene. And, when asked how she felt following the procedure, Amanda responded, “That was easy. I didn’t even feel anything.”

After performing a gingivectomy with a Biolase ezlase 940 diode laser, my 12-year-old patient, Samantha C., was asked by her mother how she felt, and Samantha responded, “Great. I didn’t feel a thing.” The next day when I called to follow-up, Mrs. C. told me that, “Samantha played with her friends from the moment she got home, and she never once complained about discomfort.”

After exposing two unerupted upper canines (“eye-teeth”) with our diode laser, Kellie M., a 12-year-old patient, stated, “I was nervous (before the procedure), but it turned out to be really easy… I didn’t actually feel a thing.”
