What are the preoperative precautions for deep overbite correction

Deep overbite correction refers to the situation where the upper and lower teeth do not fit together at all, and a fixed method is needed to correct it, improving the patient's facial teeth and achieving the effect of relief. Now many people need to complete a small operation before doing this correction. It is very important to understand the precautions of the operation. The method of the operation is not too complicated and can be completed in a short time through simple methods, quickly solving the problem of deep overbite correction.

Things to note before deep overbite correction surgery :

1. A series of preparations are required before deep overbite correction. Such as taking dental models, taking facial photos, taking X-ray positioning films, testing liver function, etc. Doctors need to determine the diagnosis and develop a treatment plan based on the data from model analysis and X-ray cephalometric measurement. For complex cases, expert professors are invited for consultation.

2. Before correcting deep overbite, it is also necessary to treat the dental and periodontal diseases in the oral cavity, such as treating caries and cleaning dental tartar. The course of orthodontic treatment is relatively long, generally 1 to 2 years.

3. Before correcting a deep overbite, you should develop the habit of brushing your teeth after meals. Each time, brush your teeth for at least 5 minutes, alternating horizontally and vertically, and use fluoride toothpaste. The removable braces should also be cleaned with toothpaste to avoid the formation of rust.

4. Before correcting a deep overbite, the prevalence of periodontal disease in adults has increased accordingly. If you have periodontal disease, you should undergo correction after the treatment is completed.

Surgical method:

One is oral orthodontic correction, which is suitable for complex malocclusion involving multiple teeth, jaw abnormalities such as underbite, overbite, etc. The treatment cycle is long, usually around 1-2 years. The other is oral restoration and correction, the main principle of which is to use porcelain crowns to restore the normal shape of the teeth. It is mostly suitable for cases with less tooth involvement and simple malocclusion. The treatment period is short and correction can be completed in about 1 week. Those seeking beauty can choose according to their own circumstances.

The main side effects of deep overbite correction are:

1. The inferior alveolar nerve mainly controls the sensation of the mandibular teeth and the skin near the lower lip. Since the nerve passes through the mandible close to the site of incision during mandibular sagittal splitting, it may be damaged by vibration and traction during the operation, or bruised when the bone is fixed.

2. Since the periosteum within the surgical range needs to be peeled off, blood clots and swelling may occur, which is medically called hematoma. The chance of occurrence is approximately 20 to 30 percent. Most hematomas are minor and will resolve on their own.

3. Since the operation is performed inside the mouth, all instruments must be inserted into the mouth, which will cause some superficial skin abrasions to the skin near the lips, especially the corners of the mouth. There is about a 50% or even higher chance of causing them. These abrasions will heal on their own in one to two weeks and usually will not leave scars.

4. Correcting a deep bite may damage facial nerve tissue, which may seriously affect facial expressions. Only under the technical operation of a professional doctor can the damage be minimized.

Preoperative precautions:

Before correction, dental molds, dental photography and X-rays are usually required. The doctor then diagnoses the type of dental malocclusion based on the model, photos and X-rays, through measurement and calculation, and develops one or several treatment plans. The plan includes which teeth need to be corrected and the oral problems that need to be resolved before correction, such as tooth decay, periodontal disease, gingivitis, cysts, etc. Different plans involve different teeth, which will mean different lengths of correction time and different future aesthetics and health.
