Benefits of Laser Dentistry over Drill Dentistry

Laser dentistry has been familiar in the last few years to treat the dental problems. Today many dentists use laser over the drill dentistry, in the dental treatments, as it offers many benefits both to the patient and the dentist. Drill dentistry is the conventional method of dentistry, which is not preferred by most of the people, as it makes them uncomfortable. So, would you like to look at the benefits of the laser dentistry? Then, go through this article.

Reduced injury
Dental drills can cause the hairline cracks and fractures in the teeth which lead to the dental problems and sometimes can cause the damage to the healthy portion of the teeth. But, by using the laser dentistry, there will not be any hard dental drills that can cause damage to the other teeth. Also, it minimizes the effect of injury.

Less swelling or bleeding
In traditional methods, scalpels were the standard methods used for addressing the soft tissues in the mouth. But, now the laser allows the great accuracy in the treatment with soft tissues. It cuts down the pain, bleeding from the patient’s mouth and also improves the recovery experience of the patients. With this, the patients can have a quicker recovery time and also the need for the anesthesia will be less.

No stitches
Dental procedures that are performed using the soft tissue dental lasers may not need stitches (Sutures).

Reduced risk of infection
As the laser treatments are very fine with high energy beam sterilizing, the area that is being worked on, there is a less potential chance or no chance of causing bacterial infections.

Accurate diagnosis
Laser helps in detecting the cavities and also the minutest bits of the teeth decay. In order to provide the accurate information with respect to the teeth and the structure of the individual teeth, a safe laser light will be focused on the surface of the teeth. By combining this with advanced digital radiography, dentists can give the patients the best, safest and general possible preventive care.

Enhanced hard tissue treatments
In most of the cavity fillings and the major dental restoration work, you probably will not see any drilling in the laser dentistry practice. As in case of soft tissues, the lasers are able to penetrate to the hard tissues of the mouth and there will not be any whirring sound. Also, no heat from friction as in the case of drilling.

These are the major benefits of using laser dentistry over the drill dentistry.

Types of Oral Appliances in Dentistry

Oral appliances are the devices applied to the patients oral cavity for a certain period of time to treat various disorders associated with the oral cavity. Oral appliances are commonly used to treat sleeping apnea and temporomandibular joint disorders.

Types of oral appliances
There are several types of oral appliances available depending on the type of disorder in oral cavity. These include:

    • Mandibular repositioning devices

Mandibular repositioning devices are made of heat sensitive acrylic material. These are custom fitted to each patient’s mouth. These are used to treat sleeping apnea. Patients with sleeping apnea have narrowed air ways during sleeping. It is fitted to the lower jaw to reposition the mandible to the normal position. This will push the tongue and soft tissue to open the air ways and restore normal breathing during sleeping.

    • Tongue retaining devices

It is used in patients with elongated tongue. It is a device used to keep the tongue in normal position during sleeping. It is used to treat obstructive sleeping apnea syndrome. It is a custom made device made up of soft pliable material. It should be worn while sleeping. It has a compartment in which tongue is positioned by means of negative pressure. Tongue retaining devices require adaptation to the patient holding tongue in the compartment. Therefore tongue exercise and adaption program is given prior to the insertion of tongue retaining device.

    • Orthodontic appliances

Orthodontic appliances are the devices applied to the teeth to position them in normal position. Orthodontic appliances include orthodontic retainers and space maintainers.

    • Orthodontic retainers are custom made orthodontic appliances used to position the teeth in its place after removal of braces. Orthodontic retainers are either fixed or removable retainers.
    • Space maintainers are used to keep the space for the permanent teeth to erupt and come out of the gums. If these are not used the gap created by the missing tooth replaced by the shifting of the adjacent teeth then surgery is necessary to correct the abnormality. These are custom made by the orthodontist and made up of plastic or metallic material. Space retainers are either fixed or removable.

Evaluation Tests Before Dental Implantation

A dental evaluation test is a must before getting the dental implantation surgery because it determines whether you are a suitable candidate for implants or not. This evaluation will usually include medical history, and other necessary tests.

The evaluation tests that are needed to prepare for the process are:

  • Medical history
  • Clinical examination with palpation
  • Radio graphs panoramic and FMX
  • ICAT

Medical history: If a person wants to replace missing teeth with dental implants then dentist will examine whether the person is suitable for implants or not. This can be done primarily by examining the medical history of that person.

  • The dentist will check if there is any growth in the jaw bone, if it is still in the growing stage.
  • Whether you have enough jaw bone density or not.
  • Gum thickness to allow placement of implant.
  • Medical history of any diseases like diabetes, tyroidism which leads to complications during surgery.
  • Whether the patient has a habit of taking alcohol and tobacco or not.
  • Whether the patient is undergoing any radiation therapy or pregnant.

Clinical examination with palpation: Clinical examination with palpation does not use any device. It can be examined by visualizing the site of missing tooth, adjacent tooth, jaw bone strength and gum tissue. This visualization is not sufficient to evaluate whether the candidate is suitable for implant or not.

Radio graphs panoramic and FMX: Dentists will take panoramic radio graphs where it shows the patients jaw bone and the teeth in the mouth in a single X-ray. X-rays shows the oral health under the surface of the teeth. If dentists want to visualize, then it is better to opt for CT scan or tomography. Tomography reveals the depth of the missing teeth and gingival margin.

FMX is another technique that helps in getting the accurate measurements for the placement of implant. FMX is a full mouth series of X-rays that should be taken every 3 years. This helps the dentist to know whether the person is suitable for dental implants or not.

ICAT: ICAT is a technique that provides 3D ultimate images of the mouth and accurately captures the patients anatomy of single tooth to entire arc. It collects precise data and measurements of bone height and length and width of the space created by the missing teeth.

These are the preliminary techniques to evaluate whether the person is suitable for dental implants or not. These tests reduces the failure of implants. So it is better to get the evaluation done before the implantation surgery.

Classification of Dental Sedatives and Anesthetics

Sedatives and anesthetics are used before dental surgery to reduce sensitivity to pain.

Sedatives Vs Anesthetics

  • Sedatives are the substances that relieves the patient’s anxiety and helps to relax and sleep.
  • Anesthetics are the agents which reduces sensitivity to pain by blocking the nerves.

Classification of dental anesthetics:
Dental anesthetics are based on level of sedation and based on the route of administration. They are classified into two types; local anesthetics and general anesthetics.

  • Local anesthetics: Local anesthetics are used to numb a particular area with out any loss of consciousness. Agents used as local anesthetics are lignocaine and novocaine.
  • General anesthetics: In general anesthetics the entire body will have temporary loss of consciousness. Agents used as general anesthetics are halothane, desflurane, isoflurane, and propofol.

Classification of dental sedation:
Dental sedation is based on the level of sedation, and are classified into; minimal sedation, moderate sedation and deep sedation.

  • Minimal sedation: Less amount of sedatives is given. Patients remain awake and communicate verbally.
  • Moderate sedation: In this state, patient remains conscious during surgery. In this state patient can not communicate. In some cases, patient may fall into sleep.
  • Deep sedation: In this type of sedation, patient is in unconscious condition during surgery and patient will not remember anything.

Classification based on route of administration:
Based on the route of administration, anesthetics used in dental surgery are classified into; inhalation sedatives, IV sedatives, oral sedatives and topical sedatives.

  • Inhalation sedatives: Sedatives are administered through nose. Dentist will place an anesthetic agent on the mask and ask you to inhale through nose and expel through the mouth. This route of administration provides less sedation effect. Nitrous oxide is the inhaled sedative.
  • IV sedatives: Sedatives are administered by injecting into intravenous nerves. Onset of action is faster as it is injecting into the vein. Duration of action depends on the amount of sedative given. Benzodiazepam and methohexital are used as IV sedatives.
  • Oral sedatives: Sedatives administered through oral route. In this a pill is taken to sleep. The pill should be taken 30 minutes before the surgery as the onset of action is slow and duration of action depends on the amount of sedative taken. Diazepam, triazolam, lorazepam are available in the form of pills.
  • Topical sedatives: Topical sedative agent is applied over the area where surgery is going to be done. It anesthetizes the mucous membrane. Now a days, patches are available. Patches contain anesthetic agent that are applied over the surface and slowly the area gets anesthetized. Benzocaine and eugenol are used as topical sedatives.

Bone Grafting and Dental Implants

Bone grafting is a surgical procedure that involves taking some tissues from high-density area and using it for bulking low-density area. In case of dental bone grafts, bone tissues are removed from one area of the body and are placed in the jawbone for improving its density and quality that makes a solid base for dental implants. This article explains about the need for the dental bone grafts and the procedure for the same.

Need for Dental Bone Grafts
When there are missing teeth, over the time the jawbone structure diminishes. After reaching certain point of jawbone loss, you cannot opt for dental implants. You may require having a bone grafting, thus ensuring that your jawbone can support dental implants. If your jawbone cannot withstand the pressure exerted by the implants during the surgery, the chances of success of dental implant surgery are very less. Moreover, bone grafting guarantees that you have a solid base for dental implants.

Procedure for Bone Grafting
Dental Bone grafting is a procedure that makes people with inadequate jawbone to enjoy the benefits of dental implants. Implants need a solid base in order to be successful. The procedure involves the following:

  • The dentist examines your mouth and carries out X-rays for confirming the depth and volume of the jaw. When he finds that the jawbone is not enough to support the dental implants, then he discusses about bone grafting.
  • Bone tissues are removed from high-density area of the body and once it is ready, the dentist makes an incision in the gum. Then the flap of tissue is lifted and the bone tissues are placed on the intended site.
  • Then the flap will be turned to its place and the gums are sutured. To protect the wound and reduce the chances of infection, a protective membrane is placed.
  • Healing time following bone-grafting surgery depends on the patient’s immune, but normally it takes 4 months’ time.
  • In extreme cases it can takes about nine months for the bone graft for developing new bone in order to support implants.

The type of bone grafting procedure depends on the number of missing teeth, the type dental implants to be used, and the location where the implants have to be placed. It has become the most common procedures for increasing the volume and quality of jawbone where the dental implants are desires to be placed.
