L’osteonecrosi maxil\u00b7lar<\/strong> \u00e9s la necrosi (mort tissular) de l’os dels maxil\u00b7lars que es produeix quan el teixit ossi perd la seva capacitat de regeneraci\u00f3 i reparaci\u00f3, quedant exposat en la cavitat oral sense capacitat de cicatritzaci\u00f3.<\/p>\n\n\n\n

La seva forma m\u00e9s freq\u00fcent i estudiada \u00e9s l’osteonecrosi maxil\u00b7lar relacionada amb medicaments (ONMM), associada a l’\u00fas de bifosfonats i altres f\u00e0rmacs antirresortius i antiangiog\u00e8nics.<\/p>\n\n\n\n

\u00c9s una complicaci\u00f3 greu, de maneig complex i amb un impacte significatiu sobre la qualitat de vida del pacient, que requereix un abordatge especialitzat des del primer signe cl\u00ednic.<\/p>\n\n\n\n

Qu\u00e8 \u00e9s l’osteonecrosi maxil\u00b7lar i com es defineix?<\/h2>\n\n\n\n

La definici\u00f3 cl\u00ednica actualment acceptada per l’American Association of Oral and Maxillofacial Surgeons (AAOMS) estableix que un pacient presenta osteonecrosi maxil\u00b7lar relacionada amb medicaments quan compleix tres criteris simultanis: tractament actual o previ amb bifosfonats o altres f\u00e0rmacs antirresortius o antiangiog\u00e8nics, pres\u00e8ncia d’os exposat o fistulitzaci\u00f3 a trav\u00e9s de la pell o la mucosa oral a la regi\u00f3 maxil\u00b7lofacial que persisteix m\u00e9s de vuit setmanes, i abs\u00e8ncia d’antecedents de radioter\u00e0pia en els maxil\u00b7lars o de malaltia metast\u00e0tica que justifiqui la lesi\u00f3.<\/p>\n\n\n\n

La distinci\u00f3 amb la osteoradionecrosis (necrosi \u00f2ssia secund\u00e0ria a radioter\u00e0pia) \u00e9s fonamental perqu\u00e8 el mecanisme fisiopatol\u00f2gic i l’enfocament terap\u00e8utic difereixen de manera significativa entre totes dues entitats.<\/p>\n\n\n\n

Quins medicaments poden causar osteonecrosi maxil\u00b7lar?<\/h2>\n\n\n\n

Els bifosfonats s\u00f3n el grup farmacol\u00f2gic m\u00e9s implicat en el desenvolupament d’osteonecrosi maxil\u00b7lar. Aquests f\u00e0rmacs s’utilitzen \u00e0mpliament en el tractament de l’osteoporosi, el mieloma m\u00faltiple, les met\u00e0stasis \u00f2ssies de tumors s\u00f2lids i la malaltia de Paget \u00f2ssia.<\/p>\n\n\n\n

Actuen inhibint l’activitat dels osteoclasts (les c\u00e8l\u00b7lules responsables de la reabsorci\u00f3 \u00f2ssia), la qual cosa redueix el recanvi ossi i la vascularitzaci\u00f3 de l’os maxil\u00b7lar, comprometent la seva capacitat de cicatritzaci\u00f3 davant qualsevol agressi\u00f3. Els bifosfonats nitrogenats administrats per via intravenosa (zoledronat, pamidronat) tenen un potencial oncog\u00e8nic significativament major que els administrats per via oral (alendronat, risedronat), utilitzats principalment en osteoporosi.<\/p>\n\n\n\n

Altres f\u00e0rmacs implicats inclouen el denosumab (antic\u00f2s monoclonal antirresortiu) i els agents antiangiog\u00e8nics com el bevacizumab o el sunitinib, fets servir en oncologia.<\/p>\n\n\n\n

F\u00e0rmac Via Indicaci\u00f3 principal Risc ONMM
Zoledronat IV Met\u00e0stasis \u00f2ssies, mieloma Alt
Pamidronat IV Met\u00e0stasis \u00f2ssies, mieloma Alt
Alendronat Oral Osteoporosi Sota
Risedronat Oral Osteoporosi Sota
Denosumab SC Osteoporosi, met\u00e0stasi Moderat-alt
Bevacizumab IV Oncologia Moderat<\/p>\n\n\n\n

Quins s\u00f3n els factors de risc m\u00e9s rellevants?<\/h2>\n\n\n\n

El risc de desenvolupar osteonecrosi maxil\u00b7lar no \u00e9s homogeni entre tots els pacients tractats amb aquests f\u00e0rmacs.<\/p>\n\n\n\n

Els factors que augmenten significativament el risc inclouen la via intravenosa d’administraci\u00f3 del bifosfonat, la durada acumulada del tractament (el risc augmenta de manera progressiva a partir dels dos anys de tractament amb bifosfonats intravenosos), la indicaci\u00f3 oncol\u00f2gica enfront de l’osteoporosi, la pres\u00e8ncia de malaltia periodontal activa, la realitzaci\u00f3 de procediments invasius sobre l’os maxil\u00b7lar (extraccions dentals, col\u00b7locaci\u00f3 d’implants, cirurgia periodontal) durant el tractament, el tabaquisme, la diabetis mellitus mal controlada i l’\u00fas concomitant de corticoides o quimioter\u00e0pia.<\/p>\n\n\n\n

L’extracci\u00f3 dental \u00e9s el desencadenant m\u00e9s sovint identificat en els casos d’osteonecrosi maxil\u00b7lar establerta, la qual cosa subratlla la import\u00e0ncia cr\u00edtica del sanejament oral previ a l’inici del tractament amb aquests f\u00e0rmacs.<\/p>\n\n\n\n

Com es diagnostica i classifica l’osteonecrosi maxil\u00b7lar?<\/h2>\n\n\n\n

El diagn\u00f2stic \u00e9s fonamentalment cl\u00ednic: la visualitzaci\u00f3 directa d’os exposat en la cavitat oral en el context d’un pacient tractat amb els f\u00e0rmacs esmentats, sense una altra causa que el justifiqui, estableix el diagn\u00f2stic. La AAOMS classifica l’osteonecrosi maxil\u00b7lar en quatre estadis segons l’extensi\u00f3 i la gravetat de la lesi\u00f3:<\/p>\n\n\n\n

Estadi Descripci\u00f3
En risc Tractament amb antirresortius sense lesi\u00f3 visible
Estadi 1 \u00d3s exposat asimptom\u00e0tic, sense infecci\u00f3
Estadi 2 \u00d3s exposat amb infecci\u00f3, dolor i eritema
Estadi 3 \u00d3s exposat amb infecci\u00f3 + fractura patol\u00f2gica, f\u00edstula extraoral o extensi\u00f3 a vora inferior mandibular<\/p>\n\n\n\n

El CBCT (tomografia computada de feix c\u00f2nic) permet avaluar l’extensi\u00f3 de la lesi\u00f3 \u00f2ssia, la pres\u00e8ncia de segrestos ossis i l’afectaci\u00f3 d’estructures adjacents, i \u00e9s imprescindible per a la planificaci\u00f3 quir\u00fargica en els estadis avan\u00e7ats.<\/p>\n\n\n\n

Com es tracta l’osteonecrosi maxil\u00b7lar?<\/h2>\n\n\n\n

El tractament dep\u00e8n de l’estadi cl\u00ednic. En els estadis inicials (estadi 1) l’abordatge \u00e9s conservador: esbandides antis\u00e8ptiques amb clorhexidina, antibioter\u00e0pia quan existeix infecci\u00f3, i evitaci\u00f3 de procediments quir\u00fargics invasius en la zona afectada.<\/p>\n\n\n\n

En els estadis 2 i 3, el tractament quir\u00fargic \u00e9s necessari: el desbridament i la resecci\u00f3 de l’os necr\u00f2tic (resecci\u00f3 marginal o segment\u00e0ria segons l’extensi\u00f3) combinats amb antibioter\u00e0pia sist\u00e8mica s\u00f3n l’abordatge de refer\u00e8ncia.<\/p>\n\n\n\n

Ter\u00e0pies adjuvants com l’oxigen hiperb\u00e0ric i el plasma ric en factors de creixement (PRGF) han mostrat resultats prometedors en s\u00e8ries de casos, encara que l’evid\u00e8ncia de nivell alt encara \u00e9s limitada.<\/p>\n\n\n\n

En Cl\u00ednica Belodonte el protocol de maneig de l’osteonecrosi maxil\u00b7lar inclou la valoraci\u00f3 individualitzada de l’estadi, l’estat sist\u00e8mic del pacient i la coordinaci\u00f3 amb l’onc\u00f2leg o reumat\u00f2leg responsable del tractament amb antirresortius.<\/p>\n\n\n\n

Com es prev\u00e9 l’osteonecrosi maxil\u00b7lar?<\/h2>\n\n\n\n

La prevenci\u00f3 \u00e9s l’estrat\u00e8gia m\u00e9s efica\u00e7 i ha d’iniciar-se abans del comen\u00e7ament del tractament amb antirresortius.<\/p>\n\n\n\n

El sanejament oral complet (extracci\u00f3 de dents amb pron\u00f2stic no recuperable, tractament periodontal, eliminaci\u00f3 de focus infecciosos) ha de realitzar-se almenys quatre setmanes abans de l’inici del tractament farmacol\u00f2gic, per a permetre la cicatritzaci\u00f3 completa dels teixits abans que el f\u00e0rmac comprometi la vascularitzaci\u00f3 \u00f2ssia.<\/p>\n\n\n\n

Durant el tractament, han d’evitar-se els procediments quir\u00fargics invasius sobre l’os en la mesura que sigui possible, i qualsevol extracci\u00f3 que sigui inevitable ha de realitzar-se amb la m\u00e0xima cura, amb sutura herm\u00e8tica de la ferida i antibioter\u00e0pia profil\u00e0ctica. Les revisions orals peri\u00f2diques cada sis mesos s\u00f3n fonamentals per a detectar qualsevol problema abans que requereixi cirurgia.<\/p>\n\n\n\n

Preguntes freq\u00fcents sobre osteonecrosi maxil\u00b7lar<\/h2>\n\n\n\n

Puc posar-me implants dentals si prenc bifosfonats?<\/h3>\n\n\n\n

La col\u00b7locaci\u00f3 d’implants dentals en pacients en tractament amb bifosfonats \u00e9s possible per\u00f2 comporta un risc augmentat d’osteonecrosi periimplant\u00e0ria, especialment en els pacients tractats amb bifosfonats intravenosos per indicaci\u00f3 oncol\u00f2gica. En pacients amb osteoporosis tractats amb bifosfonats orals a dosis baixes, el risc \u00e9s menor i la decisi\u00f3 ha de valorar-se de manera individualitzada, analitzant la durada del tractament, l’estat ossi i els factors de risc addicionals del pacient.<\/p>\n\n\n\n

Haig d’interrompre el tractament amb bifosfonats abans d’una extracci\u00f3 dental?<\/h3>\n\n\n\n

La interrupci\u00f3 temporal dels bifosfonats orals abans de procediments invasius \u00e9s una pr\u00e0ctica habitual, encara que el seu benefici real \u00e9s debatut, at\u00e8s que aquests f\u00e0rmacs s’acumulen en l’os durant anys i el seu efecte no desapareix de manera immediata en suspendre’ls. En els bifosfonats intravenosos la interrupci\u00f3 t\u00e9 encara menys evid\u00e8ncia de benefici demostrat. La decisi\u00f3 ha de prendre’s sempre en coordinaci\u00f3 amb la metge prescriptor del f\u00e0rmac.<\/p>\n\n\n\n

L’osteonecrosi maxil\u00b7lar t\u00e9 cura?<\/h3>\n\n\n\n

L’osteonecrosi maxil\u00b7lar en estadis inicials pot estabilitzar-se i fins i tot resoldre’s amb tractament conservador. En estadis avan\u00e7ats, el tractament quir\u00fargic adequat pot eliminar el teixit necr\u00f2tic i permetre la cicatritzaci\u00f3 del defecte resultant, encara que la recuperaci\u00f3 completa \u00e9s un proc\u00e9s llarg i no sempre predictible. L’objectiu terap\u00e8utic en els casos establerts \u00e9s l’eliminaci\u00f3 de l’os necr\u00f2tic, el control de la infecci\u00f3 i la millora de la qualitat de vida del pacient.<\/p>\n\n\n\n

Com s\u00e9 si tinc risc de desenvolupar osteonecrosi maxil\u00b7lar?<\/h3>\n\n\n\n

Si est\u00e0s en tractament amb bifosfonats, denosumab o altres antirresortius, has de comunicar-ho sempre al teu dentista o especialista oral abans de qualsevol procediment. Una valoraci\u00f3 oral preventiva en Cl\u00ednica Belodonte permet identificar el teu nivell de risc individual i planificar qualsevol tractament dental necessari de la forma m\u00e9s segura possible.<\/p>\n","protected":false},"excerpt":{"rendered":"
