Positions Supine are common during dentist treatment:
Positions Supine are common during dentist treatment. Many people, however, have never heard of this term. They might be surprised to learn that supine refers to a position that is lying on one’s back. This is the opposite of a prone or face-down position.Dental Chair In Positions Supine
They include the following:
Sitting in the dental chair. This is the most common position for dental treatment. In this position, you’ll be sitting with your back against a cushioned chair and your feet resting on footrests attached to the chair legs.
Laying on your back in a dental chair. In this position, your head will face forward and you’ll be lying on a padded surface with your knees bent and feet resting on footrests attached to the chair legs.
Dentists generally recommend the supine position for patients with a history of respiratory problems or those who are obese. However, dentists must be careful when using this position on certain patients because it may cause complications such as increased intra-oral pressure and difficulty breathing. In addition to these patients, dentists should use caution when employing the supine position on patients who have any of the following characteristics:
- History of heart disease
- History of stroke
- Recent surgery on their chest area (such as a mastectomy)
- A recent injury to their chest area (including broken ribs)
So when is the supine position usually used?
1. Tooth Extraction;
2. Impaction Of Teeth (Bone Grafting);
3. Infection Control (Wound Care);
4. Dental Implant Placement;
5. Anesthesia-Related Procedures (General Anesthesia);
During the treatment, the dentist should pay attention to:
During the treatment, there are three considerations: chair height, operator position, and patient position. But a dentist or operator needs to control the whole process. The two main things they must consider are the location of the dentist and chair height:
1. The height of The Dental Chair
When treating maxillary teeth, dentists need to sit higher than when treating mandibular teeth, so that they can see better when performing extractions or scaling, root planing, and other surgical procedures. The ideal height for the maxillary teeth is 30-35 cm (12-14 inches), and the chair height should be 8 cm or 3 inches below the dentist’s shoulders. The ideal height for the mandibular teeth is 25-30 cm (10-12 inches), and the height of the chair should be 16 cm or 6 inches below the dentist’s elbow level.
2. Position of operator:
The position of the dentist is the most important consideration when treating patients in the supine position. The dentist must be in a comfortable position, which makes it easy to perform some procedures, such as oral surgery, endodontic treatment and periodontal treatment.
Here are some common types of dental chairs:
- 7 o’clock position to the front of the patient’s head.
- The 9 o’clock position is on the side of the patient’s head from 10 o’clock to 11 o’clock, to the back of the patient’s head.
- 12 o’clock position, directly behind the patient’s head.
Dentists Should Pay Attention: When The Patient Is In A Supine Position
Since the patient is supine, the dentist needs to note that the patient is in the correct body position:
1. During maxillary dental treatment:
- Patient body:
The back of the chair should be at a slight 45-degree angle to the floor.
- Head position:
First, the patient’s head should be on the edge of the dry headrest. Then, the head should be turned to the contralateral side of the treatment area, with the chin slightly tucked inwards. If it is not possible to turn the head, then an assistant should support it with her hands.
- Patient’s chin position:
At this time, the patient is in the Chin-up position. The patient’s chin should be tucked inwards slightly and it should not be dropped forwards. This will prevent muscular tension and muscle fatigue during treatment.
2. During mandibular dental treatment:
- Patient body:
The back of the chair should be almost parallel to the floor.
- Head position:
The patient’s head should be on the edge of the dry headrest. The patient’s head should be resting on a headrest with their chin tilted down slightly. This will allow for greater access to the mouth and reduce pressure on jaw muscles and blood vessels.
- Patient’s chin position:
Chin down position – this helps prevent jaw muscle spasms and allows for better access (for example, when performing extractions).
Universal sitting position for the operator:
In many cases, dentists also need to maintain a healthy clinical posture. This not only makes the dentist more comfortable during the operation but also does not harm their body.
- The dentist sits in the correct natural position and approaches the patient with the forearms crossed at wrist level, not mid-abdomen.
- The dentist places the dental chair into the treatment position (upper jaw: supine position, lower jaw: semi-supine position).
- The patient’s head is then placed according to the treatment area (upper jaw: chin elevation, lower jaw, chin descent).
- The patient’s open mouth should be lower than the doctor’s elbow. In this position, the physician will not have to lift his elbow to reach the treatment position.
The supine position is a very common dental position, but it is important not to be careless during the treatment. At this time, having a comfortable dental chair can make the patient feel more comfortable and healthy. Here we recommend you choose Roson‘s dental chair,
