In the past, people thought that it was only about “aesthetics”, but in recent years, with the increase of oral health awareness, the public has realized that it is also about gastrointestinal health and quality of life. As a result, dental implants have become very popular in recent years. But how to get a successful implant in one go? What preparations do elderly people with osteoporosis, diabetes and long-term smoking need to make before dental implantation? How can dental implants be planted in order to be safe and durable? What preparations should be made before dental implant? For patients who want to have dental implants, the most worrying thing is that there will be such and such problems after the implantation, and even need to rework. How to ensure the success of dental implants in one go is not only related to the dental implant material and the skill of the practitioner, but also to whether or not adequate preparation has been done before the implantation. Many middle-aged and elderly people have been missing teeth for several years or even decades when they decide to have dental implants. For such patients who have been missing teeth for a long time, the preparation before the implantation is especially important. Under normal circumstances, teeth will constantly produce benign stimulation to the alveolar bone. When teeth are missing for a long time, the alveolar bone will undergo bone resorption due to the absence of benign stimulation, and the alveolar bone will become lower, narrower, or even flatter, which will inevitably affect the effect of dental implants. Therefore, before dental implantation, the patient should receive X-ray or 3D CT image examination, and the doctor will assess the bone volume of the alveolar bone in the implant area according to the examination result. If the bone volume is insufficient, bone extrusion is usually adopted to increase the bone volume, and in addition, surgery can be performed to increase the alveolar bone volume to meet the requirements of dental implantation in order to ensure the effect of dental implantation. Improve the success rate. Love reminds that some patients have long-term smoking, diabetes, osteoporosis, poor oral hygiene, etc. For these patients, it is also recommended to spend a period of time to adjust the treatment before implantation in order to ensure the implantation effect and get twice the result with half the effort. If the patient’s oral hygiene is poor, it is often accompanied by problems such as calculus and periodontitis. The doctor will usually advise the patient to clean the teeth and treat the oral inflammation, and the dental implant will be recommended only after the oral health condition is improved. Diabetic patients should have their blood sugar controlled and usually have a stable period of 3-6 months before they can undergo oral implant surgery. Toxic substances such as nicotine in cigarettes have a negative impact on periodontal tissues, both on the growth of epithelial tissues and on wound healing. Therefore, smoking may cause inflammation around the implant and affect the resorption of the alveolar bone, resulting in implant failure. For long-term smokers, it is recommended to quit smoking for a period of time before implantation. The impact of osteoporosis on dental implants is not yet certain. Some clinical studies suggest that osteoporosis may only increase the time of osseointegration, but the real impact on dental implants is the amount of alveolar bone. Experts suggest that in order to improve the success rate of dental implants and to ensure the implant results, patients can take some anti-osteoporosis medication to promote the osseointegration of the implants under the advice of the doctor. If the osteoporotic patient is also suffering from a lack of alveolar bone, some bone augmentation techniques can be used to increase the amount of bone tissue, after which the patient will receive dental implants with half the effort. Dental implants are now one of the best restorative techniques for teeth, and the main material is the implant and the crown. The implant is placed in the alveolar bone to act as the root of the tooth, increasing the fixedness of the denture and restoring the oral chewing force.
