Rehabilitación protésica combinando implante - diente natural / Prosthetic rehabilitation combining implant-natural tooth

Se presentó un paciente desdentado parcial que fue atendido en la consulta de Implantología de la Clínica Estomatológica "Antonio Briones Montoto" de la ciudad de Pinar del Río remitido por el Servicio de Prótesis Estomatológica de su área de salud. Perdió el lateral superior derecho desde joven y tenia preparación extracoronal en canino superior derecho. Se tuvieron en cuenta las diferentes etapas diagnósticas. Realizados los exámenes de rigor y ser aprobado su tratamiento, se colocó Mini Implante Nano. Se logró adecuada estabilidad primaria, lo que permitió, según lo planificado, pasar a la fase de rehabilitación protésica. Se cargó inmediatamente el lateral, combinando implante con diente natural. Así quedó unida la rehabilitación del 12 con el 13. El caso presentado demostró la validez de la implantología combinando implante - diente natural, dos elementos con resilencia diferente, un componente rígido como es el implante oseointegrado y un componente menos rígido como es el diente natural, se consideró al diente natural como un pilar potencial. Conclusiones: esta unión es un tratamiento clínicamente satisfactorio y efectivo a largo plazo, restableció las funciones de la masticación, estética y fonética, proporcionó mayor comodidad y mejoró la calidad de vida y socialización del paciente.

A partially toothless patient attended to the implantology Service at “Antonio Briones Montoto” Dentistry Care Clinic in Pinar del Rio city, was referred to the Prosthetic Service from the health area where he belonged to. He lost the right lateral-superior teeth when he was younger and had extra-crown preparation in right superior canine. Different diagnostic stages were considered. Usual examinations were performed in order to be chosen for the treatment, a Mini Implant NANO was placed, achieving an adequate primary stability which allowed, according to the plans, to pass to the prosthetic rehabilitation. Lateral part was immediately loaded with the combination of implant with natural tooth; this way was joined rehabilitation of 12 along with 13. The case showed the validity of implants combined with natural teeth, two elements of different resilience, a rigid component as the osseous-integrated implant and a less rigid component as the natural teeth, the natural tooth was considered as a potential mainstay. Conclusions: this union is a clinical satisfactory treatment and very effective at long term, mastication, esthetic and phonetic functions provided major comfort and improved the quality of life with socialization of patients.

Avaliação morfológica e por imagem radiográfica da matriz óssea mineralizada heteróloga fragmentada e metilmetacrilato, preservados em glicerina para reparação de falhas ósseas em tíbias de coelhos / Morphological evaluation and radiographic image of fragmented heterolog mineralized bone matrix and methylmethacrylate preserved in glycerin to repair osseous defects in tibias of rabbits

Os traumas que resultam em fraturas ósseas, principalmente as cominutivas, têm uma importância muito grande na rotina clínico-cirúrgica veterinária e humana. Foi realizada falha segmentar de 6mm na região metafisária medial da tíbia esquerda de 12 coelhos, a qual foi preenchida com implante constituído de matriz óssea mineralizada heteróloga fragmentada e metilmetacrilato, preservados em glicerina (98%) para a sua reconstrução. Foi realizada avaliação morfológica e radiológica aos 30, 60, 90 e 120 dias e observou-se a incorporação do implante ao leito receptor, em 100% dos casos, mostrando ser biologicamente compatível, pois promoveu a reparação das falhas ósseas, sem sinais de infecção, migração e/ou rejeição, sendo uma opção de substituto para preencher defeitos ósseos.

The traumas that result in bone fractures, especially comminuted, have high importance in veterinary and human surgical routine. A 6mm of segmental defect was performed at the medial metaphyseal region of the left tibia of 12 rabbits and an association of fragmented heterologue mineralized bone matrix and methylmethacrylate conserved in glycerin (98%) was used as a graft to fill the bone defect. To evaluate the procedure morphological and radiological exams were performed after 30, 60, 90 and 120 days. There was gradual integration of the bone graft in the receptor bed in 100% of the cases showing that the material is biologically compatible as it promotes bone defect reparation without signs of infection, migration and/or rejection and can be considered one more option to be used as a substitute to fill bone defects.

El avance tecnológico con respaldo científico de los últimos cuarenta años ha ubicado a la Implantodoncia dentro de la Odontología, no sólo como una filosofía de trabajo sino más bien como una verdad científica comprobada. La vigencia de la Osteointegraciòn propuesta en la década de los ochenta ha obligado a seguir investigando en la histología de la interfaz ósea de los implantes dentales como una base de sustentación científica permanente.

The technological advance with scientific support of last forty years, has located the Implantodonthics whitin dentistry, not only as a working philosophy, but rather as a scientific verified truth. The validity of the osseous integration proposed in the decade of the eighties has forced further research in the bone histology of the interface of dental implants as a base of permanent scientific support.
