Various ways and means to counter resorbed maxilla - Behnam Aghabeigi

The actual zygomatic implant placement treatment does not require almost any adjunctive care. Moreover, the ability to immediately use active dentures along with the lack of need for bone grafting as well as extended hospitalisation tends to make this kind of treatment method a lot more acceptable to the patient.

Placement of dental implants inside the posterior maxilla is usually jeopardised simply by the particular dimensions in addition to extension involving the sinus cavities as well as inadequate amounts of bone. Atrophic processes can be accelerated simply by extractible dentures too. Surgical treatments had been therefore created to raise the floor of the sinus and also fill the hereby established hole together with bone or even a alternative material, as a way to subsequently install dental implants. Autogenous bone, gathered from your iliac crest, remains the optimum bone grafting procedure which includes maxillary sinus augmentation methods. In view of the intense maxillary atrophy, the conventional surgical tactic would've been maxillary augmentation with or without a titanium mesh along with particulate cancellous bone marrow graft coming from the iliac bone. Another option happens to be a Le Fort osteotomy with an interpositional iliac corticocancellous block graft.

Extraoral bone cropping requires enhanced hospitalisation, money prices, donor site morbidity and also functional constraints. Additionally, there is certainly up to 8.6% potential for issues right after iliac crest bone graft harvesting. Even superior morbidity rates such as ache (14%) as well as neurosensory deficits (26%) have been reported lately. Finally, unpredictable decrease in size of the bone graft, on account of resorption, is a recurrent finding.

The particular endorsement regarding this approach can be low by both patients as well as clinicians due to the following grounds:

1.The actual emotional nervous about becoming put through a relatively major surgical operation

2.The actual dependence on hospitalisation and also morbidity associated with a remote donor site, especially the restricted flexibility associated with an iliac bone graft

3.Incapacity to work with the existing denture in the course of the graft recovery. This particular preventative measure should reduce graft resorption by reducing transmission of occlusal loads to the grafted site in the course of the therapeutic section

4.Greater fees of the treatment including the price of stay in hospital, use of in-patient operating services an additional surgery team for the bone tissue crop

5.Extended cure time along with late implant placement four to six months after a grafting procedure.

Simultaneous positioning of dental implants during the time of bone grafting is definitely prevented a result of decreased effectiveness when compared with overdue location.

An alternative strategy for this particular group of sufferers is the zygomaticus implant, designed by Branemark. The implant is a titanium endosteal implant starting in size from 30 mm to 52.5 mm. The actual medical procedure is performed under general anaesthesia as identified in other places. Briefly, just after bilateral elevation with the buccal mucoperiosteal tissue, elimination of the actual lateral sinus bony window posteriorly as well as reflection of the antral mucosal lining, 2 zygomatic implants are usually introduced engaging the particular dense bone tissue of the body of zygomatic arch, rising intraorally inside upper premolar region merely palatal to the alveolar crest. Each implant can be introduced in the second premolar region, spanning the maxillary sinus, and it is positioned into the body of the zygomatic bone.

Synchronous placement of at least 4 dental implants inside the canine along with the central incisor maxillary spot, allows for fabrication of mounted hybrid prosthesis. On the other hand, keeping two zygomatic implants and a minimum of two normal dental implants in conjunction with the pyriform buttresses permits construction of a bar to support a maxillary overdenture without making use of just about any bone grafting. In the event more root form dental implants can be placed inside the pre-maxilla a hard and fast prosthesis might be fabricated.
