RESUMO
It is of interest to compare guided bone regeneration (GBR) with titanium mesh, alveolar distraction osteo-genesis (DO), GBR with auto-genous bone and e-PTFE membranes and onlay bone grafts. This helps to restore vertically lacking alveolar ridges and their capacity to sustain the vertical bone growth acquired both prior to and following implant placement. The parameters such as (i) success and survival of dental implants (ii) peri-implant clinical parameters after prosthetic loading at 1 year, 2 year and 3 year follow up (iii) resorption of alveolar ridge regenerated before placement of dental implants and after placement of dental implants were assessed. Data shows that the distraction osteo-genesis is more predictable for long-term prognosis of vertical bone growth. However, all methods help to repair the vertically resorbed edentulous ridges.
RESUMO
Evaluation of four distinct obturating methods namely endodontic pressure syringe (n=40), reamers (n=40), Lentulo spirals driven through slow-speed handpiece (n=40) and incremental filling technique (n=4) using zinc oxide eugenol (ZOE) paste as obturating material in deciduous teeth is of interest to dentist. Hence, we are interested determining the effective obturation methodology using CBCT. Handpiece driven lentuspirals helped in optimum obturation in high percentage of root canals. Low percentage of optimally filled root canals was observed in reamers technique. Moreover, under filled root canals was low in lentuspirals technique of obturation. Thus, overfilled root canals were high in endodontic pressure syringe and reamers obturation technique.
