In life, it is often more difficult for people with sound teeth to experience the pain of complete tooth loss. In actuality, missing teeth not only cause severe sunken cheeks, pronunciation and chewing are greatly affected, and both physiologically and psychologically are doubly tormented. Tooth loss can seriously hinder chewing and eating, bring unnecessary burden to the stomach and intestines, and cause low immune function, which can lead to systemic diseases. In addition, once the elderly have lost too many teeth, it is easy to increase the worry about life, so that the psychological pressure is too much. From the perspective of the local oral cavity, if the lost teeth are not effectively restored for a long time, the alveolar bone will shrink over time due to the loss of strong support, and the maxillary alveolar ridge will continue to resorb upward and inward, while the mandibular alveolar ridge will continue to resorb downward and outward, forming an anti-jaw. In addition, the oral soft tissues will gradually lose their normal elasticity and tension, resulting in flattening and thinning of the mucosa, increased sensitivity, decreased masticatory muscle tension, and even TMJ disorders and pain. What are the advantages and disadvantages of full movable dentures? In the traditional way of restoring missing teeth, movable denture has been a simple and widely indications of the restoration method. According to Wang Linhu, full removable denture restoration is to use the alveolar bone and mucosal support, with the help of atmospheric pressure and saliva adhesion to hold the denture in place. This full movable denture are relatively large, just wear the patient easily feel uncomfortable, some patients may also have allergies, vomiting and other uncomfortable symptoms, can restore the chewing function is also limited. In the past, patients with high requirements for comfort would choose denture with light, thin, high strength cobalt-chromium alloy, pure titanium and other bases. However, it should be noted that full removable dentures of any material cannot stop the problem of alveolar bone atrophy and resorption. Over time, the fit of the dentures in contact with the dental bed will be reduced and inevitably loosen and become unstable when worn, and can only be constantly adjusted or replaced. What are the characteristics of dental implant restoration? In recent years, the new restoration method of dental implant restoration has overturned the tradition and become a popular choice for many patients with missing teeth. The main reason why dental implant restoration is highly praised is that it is different from movable dentures that rely on retaining rings to hook adjacent teeth or abutments to attach to the alveolar bone, and it is also different from porcelain teeth that need to be ground and altered to fix the neighboring teeth, it is a new restoration method that implants similar to natural tooth roots are placed into the alveolar bone, and then crowns are restored on them. Since the structure and chewing force principle are similar to those of real teeth, the chewing force can be transferred to the alveolar bone and distributed to the larger supporting bone, just like real teeth, so that the chewing efficiency of real teeth can be restored to the maximum. However, another immediate implant technology allows implant surgery to be performed at the same time as tooth extraction. For example, the high-tech bionic dental implant technology carried out by the Wuhan General Hospital Dental Center of Guangzhou Military Region is to scan and locate the patient’s alveolar bone through a digital imaging system, then create a positioning guide plate based on the relevant data, extract the affected tooth in a minimally invasive way, and at the same time preserve the alveolar bone tissue for optimal implantation conditions and immediately place the bionic dental root. This not only fills and supports the alveolar socket and prevents atrophy, but also saves a lot of time for the patient. How to restore a toothless mouth with implants? Since implant bionic teeth are so powerful, can patients with total edentulousness also regain their teeth through implant restoration? The use of implant restorative technology allows edentulous patients to enjoy more stable restorative results. For this group of patients, they may often worry about having to “plant one without the other” to rebuild a full mouth of good teeth. One is a full jaw fixed implant denture and the other is a removable full jaw overlay implant denture. The difference is that in the former case, the bridge crown is directly fixed to the bionic root and cannot be removed by the patient; in the latter case, the bionic root has a special superstructure that can be combined with a bar, sleeve crown, ball cap or magnetic attachment to the removable denture, allowing it to gain retention. In this way, the bionic root is like a “bridge pier” in the mouth, the traditional denture is like an “overpass”, after playing a good “bridge pier” overpass can be stable, so since the chewing The force is also enhanced. Generally speaking, the more “piers” there are, the stronger the support will be, and the stronger the function of the denture will be. If the patient is physically fit, tolerant, has good alveolar bone and is financially well off, more bionic roots can be placed to restore the tooth function as much as possible. If the patient is weak and the alveolar bone is shrinking, a few less implants can partially restore the chewing function and enhance the retention force. From a clinical point of view, the ball-cap retained implant overdenture supported by two bionic roots is less invasive, the most economical and practical, and relatively easy to clean and maintain afterwards, making it the preferred solution for edentulous patients. Overall, the implant prosthetic technique provides good retention and stable support in the clinical application of total edentulous restoration, enhances the masticatory efficiency of the denture, and improves the satisfaction of the edentulous patients with the denture.
