As time is passing, more and more people lose one or more teeth because of tooth decays, injuries, ageing or periodontal diseases. Living without having teeth is embarrassing and uncomfortable, affecting the way someone talks, their aspect and their capacity of chewing and eating.
Even if there are plenty of options for missing teeth replacement, the dental implant is a solution that offers a natural sensation which help patients to rediscover their functional and healthy smile. Dental surgery for implants is performed in order to replace missing or much damaged teeth in safety conditions. During surgery, an implant made of titanium alloy is inserted in the patient’s maxillary which integrates naturally in the bone in a few weeks.
A dental implant has the same function as the root of a natural tooth, offering solid support for a new tooth. There are also used dental implants to support prostheses or for replacing complete edentulous arches (when all the teeth are missing).
The implant is efficient for patients who wear an inferior prosthesis and wish additional support. Firstly, there are inserted 2 or 4 dental implants in the inferior maxillary and let them to cure for 90 days. Secondly there are attachments introduced in the implants, these attachments being the connection between the existent prosthesis and the implants.
Many people are suffering from a bone loss after losing teeth because of injuries, traumatizing extractions or pariodontal diseases. Because the human body sometimes reabsorbs the section of the maxillary which is not used, the patients can remain with an unfit bone structure for dental implant insertions. The reabsorbed section can be reconstructed by using the patient’s own bone or an artificial one, this resulting in a natural and secure foundation for each dental implant. Bone engraftment is necessary when there is done a restauration through a dental implant immediately after a tooth extraction. For these treatments, the use of a bone graft around the dental implant offer structural support which allows the maxillary to cure properly.
A sinus lift, or a raise of the sinus membrane, is an extremely complicated procedure which would normally be effectuated ONLY by a surgeon. This surgery is used for the raise of bone quantity from the superior maxillary before the restauration by dental implant. Many times, the teeth roots only get to the maxillary sinus situated above the superior teeth. When a tooth is extracted, sometimes remains only a thin bone portion between the sinus and the oral cavity. The implants must be firmly anchored in the patient’s maxillary, and the lack of a sufficient bone structure may endanger the implant. During the sinus lift procedure, we enter in the sinus through the lateral wall of the maxillary, and we “lift” the sinus’s membrane in order to make space in the superior maxillary’s ceiling for the bone graft and the implant. There, the surgeon introduces the bone graft and in the majority of the cases, introduces the implants too. Patients must wait a few months for the graft and the dental implant to integrate before the replacing teeth or tooth settlement.
The dental implant insertion in the inferior maxillary sometimes needs surgical interventions for the nerve repositioning when the restoration on dental implant is happening. If the bone loss from the inferior maxillary is significant, the dental implant insertion might not be possible without damaging the inferior alveolar nerve, case in which the nerve repositioning is necessary.
