Resumo: | Introduction: Excessively traumatic surgery can adversely affect the maturation of bone tissue and consequently diminish the predictability of osseointegration so the mechanical and thermal damage should be minimized during surgical procedure. The purpose of this study is to evaluate immediate histological alterations in rabbit tibias, produced by low speed drilling (50 rpm) without irrigation and conventional drilling (800 rpm) under profuse irrigation.Material and Methods: Thirty-six implant osteotomies were created in the tibias of 6 White female rabbits. Drilling began with a 1.5 mm round bur, followed by 2.0 mm, 2.5 mm and 3.5 mm helical drills. The posterior tibial cortex was evaluated as the positive control, and it was preserved during the surgical procedure. The receptor beds were collected for histological analysis.Results: All defects showed regular edges. Hematoxylin eosin (HE) sections showed that both techniques preserved the bone structure and the presence of living cells. No histological differences between the two surgical drilling techniques were found.Conclusions: Based on our results, we can conclude that the effects of implant site preparation on bone by low speed drilling (50 rpm) without irrigation and conventional drilling (800 rpm) under abundant irrigation are similar. Both surgical drilling techniques preserve bone-cell viability and the clinician can decide which drilling technique to use, based on other criteria. |

O objectivo deste estudo foi avaliar as alterações histológicas imediatas provocadas pela osteotomia a 50 rpm sem irrigação e a 800 rpm com irrigação, no osso do coelho.Material e Métodos: Foram efectuadas 36 perfurações (18 com cada técnica) nas tíbias de seis coelhos adultos. A sequência debrocas utilizada foi: uma broca esférica com 1,5 mm de diâmetro, uma broca piloto com 2,0 mm de diâmetro, e uma broca com 3,5 mm de diâmetro. A cortical posterior das tíbias foi preservada, constituindo o osso de controlo. Procedeu-se à recolha das tíbias com os defeitos a analisar, para observação com microscópio óptico e análise qualitativa.Resultados: Os defeitos ósseos apresentaram bordos regulares. Observou-se tecido ósseo viável, vascularizado e com presença de osteócitos junto aos defeitos. A estrutura haversiana e lamelar do tecido encontrou-se mantida, bem como a rede vascular. A matriz extracelular não apresentou alterações. Os resultados indicam não haver diferenças histológicas entre as osteotomias a 800 rpm com irrigação e a 50 rpm sem irrigação.Conclusão: O nosso estudo sugere que as alterações no tecido ósseo provocadas pela osteotomia a 50 rpm sem irrigação e a 800 rpm com irrigação são semelhantes, e que ambas as técnicas mantêm o tecido ósseo viável para a colocação de implantes e respectiva osteointegração, cabendo ao clínico a escolha, em função de outras variáveis.Ordem dos Médicos2013-06-21info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/4250oai:ojs.www.actamedicaportuguesa.com:article/4250Acta Médica Portuguesa; Vol. 26 No. 3 (2013): May-June; 231-236Acta Médica Portuguesa; Vol. 26 N.º 3 (2013): Maio-Junho; 231-2361646-07580870-399Xreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPenghttps://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/4250https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/4250/3355Gaspar, JoãoBorrecho, GonçaloOliveira, PedroSalvado, FranciscoMartins dos Santos, Joséinfo:eu-repo/semantics/openAccess2022-12-20T11:03:30Zoai:ojs.www.actamedicaportuguesa.com:article/4250Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T16:18:46.224164Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
