ABSTRACT
A Saucerização Óssea Peri-implantar Cervical, ou simplesmente Saucerização, deve ser considerada uma adaptação morfológica e funcional dos tecidos cervicais peri-implantares. O homem conseguiu imitar a natureza, e os implantes osseointegráveis simulam o dente: parte dentro do meio interno e parte no meio externo. O epitélio juncional peri-implantar leva o EGF próximo ao osso vizinho, que se reabsorve de forma inclinada. Esse processo é inevitável e independe do design, tipo ou marca comercial dos implantes osseointegráveis. Tridimensionalmente, o formato final do osso cervical peri-implantar imita um pires e pode sofrer influências de fatores cirúrgicos, bem como do tipo ósseo, designs, carga oclusal, tempo de uso, grau de higienização e muitos outros fatores. Porém, negar o processo implica em ignorar alguns aspectos da biopatologia óssea. Todos os 206 ossos humanos são arredondados e suas funções não permitem ângulos retos em suas margens e limites.
Cervical periimplant bone saucerization, or simply saucerization, should be considered a morphological and functional adaptation of peri-implant cervical tissues. Humans were able to mimic nature. Osseointegrated implants imitate natural teeth: half inside the alveolar bone and half in the oral environment. Peri-implant junctional epithelium takes the epidermal growth factor near neighboring bones which is reabsorbed in an inclined manner. his process is unavoidable and occurs regardless of implant design, type and commercial brand. hree-dimensionally, peri-implant cervical bone resembles a saucer and might be afected by surgery, the type of bone, implant design, occlusal load, time of use, sanitization and several other factors. Nevertheless, denying the process means ignoring some features of bone biopathology. All 206 human bones are round-shaped and, for this reason, do not allow straight angles at their borders and limits.

Treatment of chronic localized osteomyelitis is the same as the other osteomyelitis, that is, curettage and debridement of all dead tissue which is called saucerization. After saucerization there leaves empty cavity and autogenous bone graft has been used for filling the cavity in lower extremity hecause of weight bearing and avoiding fracture. We treated seven cases of chronic localized osteomyelitis with one-staged saucerization and cancellous chip allograft and retrospective analysis was done. All healed without complication and no recurrence was ohserved. Most orthopaedic surgeons are not willing to use allograft on the site of osteomyelitis because of the fear of recurrence. But. we think that as far as complete removal of infected and dead tissue, allograft could he a good solution in terms of rapid remodelling and early weight hearing. Another advantages of allograft are to get a large amount of bone and no damage of iliac apophysis. In summary, one-staged saucerization and cancellous chip allograft would he very useful treatment for chronic localized osteomyelitis.

From May, 1971 to June, 1984, we performed extensive saucerization on the chronic osteomyelitis of long bones eradicating all pathologic foci; not only sequestra but sclerotic involocurum and necrotic original cortex embeded by new bone, which was different from the conventional methods such as sequestrectomy or guttering in its extensiveness. Clinical analysis on the base of radiologic evaluation after saucerization was done on the 16 patients; for average 5 years of follow-up. The results obtained were as follows; 1. The angulatory deformity of the long bones after pathologic fracture complicated by the chronic osteomyelitis was not corrected satisfactorily due to the bony sclerosis or hyperostosis at the fracture site, especially in cases of posterior or medial angulation. 2. The recurrence was closely related to the persisting non-sequestered original cortical lesion after incomplete saucerization, which was embeded by the new bone. So to prevent the recurrence the non-sequestered original cortical lesion must be removed completely. 3. The cortical defect after saucerization was restored completely in patients under the age of 14, but which was not the way in patients over the age of 16.
