Laser therapy for peri-implantitis

 


It is well known that the popularity of oral implants is increasing every year as people's living standards improve. The number of patients with peri-implantitis has increased rapidly in recent years due to the treatment conditions and the lack of awareness of patient protection at a later stage. If peri-implantitis is not treated promptly and effectively, it can lead to the loss of the implant.


Peri-implant infections have a similar etiology to periodontal infections, so is the treatment similar?


Conventional treatment options for peri-implantitis without flap reversal have a poor chance of success. When we treat peri-implantitis after flap treatment, the outcome is much better. Although the flap allows better access to the implant, the sterilisation of the implant surface is much more complex than with normal subgingival scraping. The complex structure of the implant surface, although a good facilitator of bonding during implantation, is a headache trap for peri-implant infections. As a result, the tools utilised in the treatment of periodontitis have difficulty in completely removing the bacteria and infected tissue from the implant surface, making their use much less effective.

Using the properties of oral laser wavelengths and biological tissue absorption, lasers can act as bacterial killers and biostimulators. In particular, the wavelength of the semiconductor laser is in the near infrared band, so the 980nm wavelength has a good absorption effect on the melanin carried by bacteria and can be more effective in killing them. In addition, the 650nm wavelength has a biostimulating effect and accelerates tissue recovery, making it the tool of choice for peri-implantitis treatment.

Objectives of peri-implantitis treatment

1. Reduce implant infection

2. Strengthen the bond with the bone

 

In order to achieve this goal, the implant surface should be free from any foreign bacterial or toxin infection. If cleared, previous tissue inflammation will recover quickly and the patient's own healthy cells will re-attach to the implant surface. The key to the treatment of peri-implantitis is the removal of infected material and toxins from the implant surface.

 

Traditional cleaning methods including the use of scrapers or ultrasound devices are limited in the treatment of peri-implantitis. If laser treatment is used in addition to the traditional treatment modalities, it can be very sterilising, disinfecting and biostimulating.


Stay tuned, in the next chapter you will read about the PIOON S3 blue 3-wavelength dental laser for periodontal treatment.

Are Laser Dental Procedures Better Than Traditional Treatments?

图片
Dental laser   is the use of lasers to treat a number of different dental conditions. It became commercially used in clinical dental practice for procedures involving tooth tissue in 1989. Dental laser potentially offers a more comfortable treatment option for a number of dental procedures involving hard or soft tissue compared to drills and other non-laser tools. Lasers can make  dental treatments  more efficient, cost effective, and comfortable. The Food and Drug Administration (FDA) has approved dental laser as a treatment option for several dental conditions. The type of surgery that can be performed with a dental laser depends on the wavelength and power of the dental laser. Pioon dental laser can perform the following dental laser procedures. Including: Teeth whitening. Treating cold sores. Treating a “gummy smile.” Treating obstructive sleep apnea. Treating tongue frenulum attachment. Viewing tissues. Nerve regeneration.  Crown lengthening . Removing benign tu...

PLDD-Let your intervertebral disc no longer “protrude”

图片
  Patients with   intervertebral  disc herniation are mostly between 30 and 50 years old, and there are more men than women. The most common site is the lumbar spine, followed by the cervical spine (because these two sites are the sites with greater spine mobility). Lumbar disc herniation is a frequently-occurring and common disease in clinical practice, and it is the most common cause of low back and leg pain. The disease mostly occurs in young adults, and part of it occurs in the elderly. The patient suffers a lot. In severe cases, it can cause paraplegia, which can have a great impact on the life, work and labor of the patient. The cause of lumbar disc herniation is more complicated. At present, it is generally believed that the herniated disc is mainly caused by corresponding damage on the basis of degeneration. Internal cause: The intervertebral disc tissue bears the weight of the human body's trunk and upper limbs, and is more likely to be strained than other tissue...

Lip Depigmentation with Laser

图片
  Oral Mucosa is normally pink, although the color varies depending on location, function and underlying structures. Lips are an important part of our smiles; the shape and color are crucial elements of the lip's beauty. The color of the lips normally varies from person to person depending on factors such as melanin production, skin color, vascularity, and dryness (dehydration) of the lips. Among these, the major factor contributing to the color of lips is melanin.  Lip hyperpigmentation  does not pose any medical problem, but usually considered unaesthetic and can affect the patient’s social activities and self-confidence and patients are seeking solutions. Etiology - The most common cause is physiologic i.e. hyper-melanin pigmentation. After ruling out any malignant changes, the Laser is used electively for removing pigmentation from the lips. Treatment modality - Many techniques have been used for the treatment of lip depigmentation. Melanin pigmentation normally exist...
