Estudo retrospectivo de implantes osseointegrados instalados imediatamente após exodontias

Objectives: to evaluate implant survival immediately placed after tooth extraction considering different sites, prosthodontic modalities, and the need for biomaterials. Material and methods: dental records of 500 patients treated with dental implants between 2004 and 2011 were screened. Results: only 200 records (20%) corresponded to immediate implants. Reasons for tooth extraction included extensive caries, bone loss, and root fractures. From the 197 immediate dental implants, 86 were placed in the maxilla with a survival rate of 93.9% and 111 in the mandible (survival rate of 99.1%). The overall survival rate was 97.46%. Prosthodontic modalities identified were: Brånemark classic complete denture screwed prostheses (36%), overdentures (5.6%), fixed partial denture (31%), and single-tooth prostheses (27.4%). Also, it was observed that in 33% of cases there was a need for the use of grafts and/or biomaterials. Conclusion: it can be concluded that, when correctly indicated, immediate implants are an excellent choice. The anterior mandibular region, screwed and overdenture-type prostheses presented higher success rates when associated to immediate implant placement. The need for bone graft/biomaterial does not affect the clinical results.

Avaliação do índice de sucesso dos enxertos autógenos e dos implantes instalados em região de seio maxilar

Maxillary sinus lifting surgery is considered an excellent option for patient rehabilitation in cases of maxillary sinus pneumatization. This longitudinal study was performed in 41 patients to evaluate 51 maxillary sinus lifting procedures concomitant to autogenous bone grafted from mandibular ramus. Of the 107 implants installed, 28 were immediate fixations. Success index achieved regarding to bone graft was of 98.04%. The implants installed immediately or after bone grafting resulted in success rates of 92.86% and 94.59% respectively, with no statistically significant differences between them. Surgeries for bone grafting and immediate installation are considered a reliable treatment alternative provided that both anatomical structures and tissue physiology are kept in good conditions, with appropriate indication and techniques for good implant stability.

Sobrevivência de enxertos de Eucalyptus com metodologia adaptada

One of the important techniques to assist a tree improvement program is the grafting, which is used for the propagation of selected trees. The objective of this study was to evaluate the survival rate using a modified method of lateral grafting on Eucalyptus dunnii, Eucalyptus urophylla and a hybrid of Eucalyptus urophylla x Eucalyptus grandis. The work was conducted by the research teams of Eucatex and Palmasola companies, in September of 2011, and 589 grafts were made. The survival rate of the grafts was evaluated 180 days after grafting. Survival grafts rates were: 74% for E. dunnii, 55% for E. urophylla and 62% for the hybrid E. urophylla x E. grandis. These survival rates were higher than those currently obtained by the conventional method of eucalypt grafting. Thus, the method seems promising to assist in forest tree improvement programs, but further studies are still necessary to refine this grafting approach.
