There are many kinds of dental implants in the workshop, and some manufacturers promote all kinds of rapid and minimally invasive dental implants. Consumers should compare in many ways and make wise choices.
Doctors emphasize that dental implant is a precise operation, which is closely related to the depth, width and density of alveolar bone. If the height of the bone bed before dental implantation is lower than the length of the implant, the current technology can be combined with maxillary sinus elevation to increase the height, achieve the best safe distance and protect the maxillary sinus.
As for the reason of the lack of bone bed in sinus area, what is the reason? The doctor pointed out that it includes patients with severe periodontal disease and serious bone erosion in the maxillary posterior teeth area, or apical cyst caused by root inflammation, or bone bed atrophy caused by tooth loss for too long, and bone bed damage was too large during tooth extraction, but it was not repaired.
Most patients have better bone condition in the mandibular posterior teeth area than in the maxillary area, and relatively few patients need bone repair. However, doctors believe that the most difficult thing in mandibular reconstruction is that the height of the bone must avoid the nerve, or when the alveolar bone is drilled and implanted, a safe distance should be kept above the mandibular nerve canal to avoid damaging the inferior alveolar nerve. There are also many journal articles about dental implants, which advocate that dental implants in mandibular region should keep a safe distance of 2mm, that is, to avoid the possible consequences of nerve injury.
In the past, dental implant surgery could only judge the thickness of dental bone bed according to X-rays. If the interpretation is wrong, it will easily lead to medical negligence. Now 3D full-mouth computed tomography can be used, which can clearly display the patient's oral image and accurately evaluate the bone injury. Before the operation, the surgical positioning template was made to position the gingival bone implant in the best position and adjust the correct occlusion. Then, combined with the on-site monitoring system, the doctor can monitor while planting teeth and implant the implant in the right position accurately. It can also prevent the risk that the maxillary sinus is punctured and the mandibular nerve is injured, or the implant is too shallow and unstable, greatly reducing the failure rate of the implant and reducing medical disputes.
If you want to successfully implant teeth, you must do it step by step. First of all, we should ensure the stability of the dental implant area. Patients with periodontal disease can choose low-pain water wave laser to treat periodontal disease and reduce infection and inflammation. The longer the tooth is missing, the more serious the bone loss is. If the bone is particularly serious, it is necessary to fill the bone first, promote bone regeneration, and let the gum bone have sufficient conditions before implanting teeth. If you choose to implant your teeth quickly because you are greedy and cheap, you should be careful that the implants are easy to loosen, and haste makes waste.
The doctor also reminded that patients should clearly inform themselves whether they have a history of sinusitis before dental implantation, so as to consider and judge dental implantation and bone filling. Patients with dental implants should avoid smoking, do a good job of oral cleaning, and remember to make regular follow-up visits after surgery, so as to find problems and remedy them as soon as possible.
