La regeneraci\u00f3 \u00f2ssia guiada <\/strong>(ROG) \u00e9s una t\u00e8cnica quir\u00fargica que permet reconstruir el volum d’os perdut en els maxil\u00b7lars quan aquest \u00e9s insuficient per a col\u00b7locar un implant dental en condicions \u00f2ptimes.<\/p>\n\n\n\n

\u00c9s un dels procediments m\u00e9s utilitzats en implantologia avan\u00e7ada i, en mans d’un especialista amb experi\u00e8ncia, ofereix resultats predictibles i duradors.<\/p>\n\n\n\n

Entendre en qu\u00e8 consisteix, quan est\u00e0 indicada i qu\u00e8 implica la seva recuperaci\u00f3 ajuda el pacient a prendre decisions informades sobre el seu tractament. Des de Cl\u00ednica Belodonte, experts en Implants dentals a Barcelona<\/a><\/strong>, parlem sobre aix\u00f2.<\/p>\n\n\n\n

Per qu\u00e8 es perd os en els maxil\u00b7lars?<\/h2>\n\n\n\n

L’os alveolar (el que envolta i sost\u00e9 les dents) \u00e9s un teixit viu que reacciona de manera directa als est\u00edmuls mec\u00e0nics que rep. Quan una dent es perd, l’abs\u00e8ncia d’aquesta c\u00e0rrega funcional provoca una reabsorci\u00f3 progressiva de l’os en aquesta zona, que pot ser significativa en els primers dotze mesos despr\u00e9s de l’extracci\u00f3 i continuar a un ritme m\u00e9s lent durant anys.<\/p>\n\n\n\n

Altres factors que contribueixen a la p\u00e8rdua \u00f2ssia inclouen la malaltia periodontal avan\u00e7ada, els traumatismes, les infeccions cr\u00f2niques periapicals, la pressi\u00f3 de pr\u00f2tesis amovibles mal ajustades i determinades malalties sist\u00e8miques com l’osteoporosi o la diabetis mal controlada.<\/p>\n\n\n\n

El resultat \u00e9s un vorell alveolar insuficient en ampl\u00e0ria, en altura o en totes dues dimensions, que impedeix la col\u00b7locaci\u00f3 d’un implant en la posici\u00f3 prot\u00e8sicament ideal.<\/p>\n\n\n\n

En qu\u00e8 consisteix la t\u00e8cnica de regeneraci\u00f3 \u00f2ssia guiada?<\/h2>\n\n\n\n

La ROG es basa en el principi de crear un espai protegit on les c\u00e8l\u00b7lules \u00f2ssies del pacient puguin proliferar i formar os nou sense la interfer\u00e8ncia del teixit tou (geniva i connectiu), que creix molt m\u00e9s r\u00e0pid que l’os i colonitzaria aquest espai abans que el teixit ossi pogu\u00e9s regenerar-se.<\/p>\n\n\n\n

Per a aconseguir-ho, el cirurgi\u00e0 col\u00b7loca una membrana de barrera (reabsorbible o no reabsorbible, segons el cas) sobre el defecte ossi, que actua com una estructura selectivament permeable: permet el pas de nutrients i c\u00e8l\u00b7lules osteog\u00e8niques procedents de l’os adjacent, per\u00f2 impedeix la invasi\u00f3 del teixit tou.<\/p>\n\n\n\n

L’espai sota la membrana s’emplena habitualment amb material d’empelt (os aut\u00f2leg del propi pacient, os de banc, materials sint\u00e8tics o una combinaci\u00f3 d’ells) que actua com a bastimentada per a la formaci\u00f3 d’os nou.<\/p>\n\n\n\n

Quan est\u00e0 indicada la regeneraci\u00f3 \u00f2ssia guiada?<\/h2>\n\n\n\n

La indicaci\u00f3 principal de la ROG \u00e9s la insufici\u00e8ncia de volum ossi per a col\u00b7locar un implant amb estabilitat prim\u00e0ria adequada i en la posici\u00f3 tridimensional correcta des del punt de vista prot\u00e8tic.<\/p>\n\n\n\n

Les situacions m\u00e9s freq\u00fcents que requereixen ROG inclouen els defectes ossis horitzontals (falta d’ampl\u00e0ria del vorell), els defectes verticals (falta d’altura), els defectes combinats i els defectes periimplant\u00e0ris en implants ja col\u00b7locats. Tamb\u00e9 s’indica en el moment de l’extracci\u00f3 dental (preservaci\u00f3 alveolar) per a minimitzar la reabsorci\u00f3 \u00f2ssia postextracci\u00f3 i mantenir el volum ossi de cara a la futura col\u00b7locaci\u00f3 de l’implant.<\/p>\n\n\n\n

La planificaci\u00f3 mitjan\u00e7ant CBCT (tomografia computada de feix c\u00f2nic) \u00e9s imprescindible per a determinar amb exactitud el tipus i la magnitud del defecte abans de dissenyar el pla quir\u00fargic.<\/p>\n\n\n\n

Quins materials s’utilitzen en la regeneraci\u00f3 \u00f2ssia?<\/h2>\n\n\n\n

L’elecci\u00f3 del material d’empelt dep\u00e8n del tipus de defecte, de la seva extensi\u00f3 i de les caracter\u00edstiques del pacient. L’os aut\u00f2leg (obtingut del pacient, habitualment de la zona de la barbeta, la branca mandibular o zones intraorals adjacents) \u00e9s el material amb potencial osteog\u00e8nic m\u00e9s alt (capacitat de formar os nou de manera activa), per\u00f2 implica una segona zona quir\u00fargica donant.<\/p>\n\n\n\n

L’os d’origen bov\u00ed (xenoempelt) \u00e9s el material de substituci\u00f3 \u00f2ssia m\u00e9s utilitzat en la pr\u00e0ctica cl\u00ednica per la seva alta biocompatibilitat, la seva reabsorci\u00f3 lenta i predictible i la seva \u00e0mplia evid\u00e8ncia cient\u00edfica. Els materials sint\u00e8tics (al\u00b7lopl\u00e0stics) com el fosfat tric\u00e0lcic o la hidroxiapatita s’usen solos o en combinaci\u00f3 amb altres materials.<\/p>\n\n\n\n

La tend\u00e8ncia actual apunta cap a l’\u00fas de mescles personalitzades que combinin les propietats osteog\u00e8niques de l’os aut\u00f2leg amb l’estabilitat volum\u00e8trica dels xenoempelts.<\/p>\n\n\n\n

Quant temps requereix la regeneraci\u00f3 \u00f2ssia abans de col\u00b7locar l’implant?<\/h2>\n\n\n\n

El per\u00edode de maduraci\u00f3 de l’os regenerat varia en funci\u00f3 del tipus i la magnitud del defecte tractat. En els casos de ROG simult\u00e0nia a la col\u00b7locaci\u00f3 de l’implant (quan existeix prou estabilitat prim\u00e0ria), el per\u00edode d’osteointegraci\u00f3 habitual \u00e9s de tres a sis mesos.<\/p>\n\n\n\n

Quan la ROG es realitza com a procediment previ a la col\u00b7locaci\u00f3 de l’implant (en dues fases), el per\u00edode d’espera perqu\u00e8 l’os regenerat maduri prou oscil\u00b7la entre quatre i nou mesos, segons el volum regenerat i el tipus de material utilitzat.<\/p>\n\n\n\n

Durant aquest per\u00edode, el seguiment cl\u00ednic i radiol\u00f2gic \u00e9s fonamental per a verificar la correcta evoluci\u00f3 de la regeneraci\u00f3.<\/p>\n\n\n\n

Quins s\u00f3n els factors que influeixen en l’\u00e8xit de la regeneraci\u00f3 \u00f2ssia?<\/h2>\n\n\n\n

El tabac \u00e9s el factor que m\u00e9s negativament influeix en el resultat de la ROG: redueix l’aportaci\u00f3 sangu\u00ednia als teixits, altera la resposta immunit\u00e0ria i augmenta de manera significativa el risc d’exposici\u00f3 de la membrana i frac\u00e0s de l’empelt.<\/p>\n\n\n\n

La diabetis mal controlada, la radioter\u00e0pia pr\u00e8via en la zona maxil\u00b7lofacial i determinats f\u00e0rmacs com els bifosfonats o els anticoagulants tamb\u00e9 poden comprometre el resultat. L’experi\u00e8ncia del cirurgi\u00e0 i la correcta execuci\u00f3 t\u00e8cnica (estabilitat del co\u00e0gul, hermeticitat del tancament de la ferida, elecci\u00f3 adequada de la membrana i el material d’empelt) s\u00f3n determinants.<\/p>\n\n\n\n

En Cl\u00ednica Belodonte la planificaci\u00f3 de cada cas de ROG es realitza de manera individualitzada, amb el suport de tecnologia d’imatge tridimensional i un protocol quir\u00fargic estandarditzat que minimitza les variables de risc.<\/p>\n\n\n\n
