Les dents supernumer\u00e0ries<\/strong> s\u00f3n dents addicionals que es desenvolupen per sobre del nombre normal de peces dentals. La dentici\u00f3 permanent adulta consta de 32 dents, i qualsevol pe\u00e7a que superi aquest n\u00famero es considera supernumer\u00e0ria. Encara que la seva prevalen\u00e7a \u00e9s relativament baixa (entre l’1% i el 3% de la poblaci\u00f3 segons la literatura odontol\u00f2gica), el seu impacte sobre l’erupci\u00f3, l’alineaci\u00f3 i la salut de la resta de la dentici\u00f3 pot ser molt significatiu si no es detecten i tracten a temps. En la majoria dels casos el diagn\u00f2stic \u00e9s radiol\u00f2gic i el tractament \u00e9s quir\u00fargic. Des de Cl\u00ednica Belodonte, experts en Cirurgia Oral i Maxil\u00b7lofacial a Barcelona<\/a><\/strong>, expliquem acosta aquesta situaci\u00f3 i el seu abordatge.<\/p>\n\n\n\n

Per qu\u00e8 es formen les dents supernumer\u00e0ries?<\/h2>\n\n\n\n

L’origen exacte de les dents supernumer\u00e0ries no est\u00e0 completament esclarit. La teoria m\u00e9s acceptada \u00e9s la hiperactivitat de la l\u00e0mina dental (el teixit embrionari del qual deriven totes les dents), que genera un germen dentari addicional de manera espont\u00e0nia.<\/p>\n\n\n\n

Existeix un component gen\u00e8tic documentat: la prevalen\u00e7a de dents supernumer\u00e0ries \u00e9s significativament major en familiars de primer grau de pacients afectats. Tamb\u00e9 s’associen a determinades s\u00edndromes i condicions sist\u00e8miques, entre els quals destaquen la disostosi cleidocraneal (en la qual els supernumeraris m\u00faltiples s\u00f3n una caracter\u00edstica definit\u00f2ria), la s\u00edndrome de Gardner, el paladar fenedura i la fissura llavipalatina. Quan apareixen de forma a\u00efllada, sense associaci\u00f3 sindr\u00f2mica, es denominen supernumeraris no sindr\u00f2mics i representen la gran majoria dels casos que s’atenen en la pr\u00e0ctica cl\u00ednica habitual.<\/p>\n\n\n\n

On es localitzen amb m\u00e9s freq\u00fc\u00e8ncia i com es classifiquen?<\/h2>\n\n\n\n

El mesiodens \u00e9s el tipus de dent supernumer\u00e0ria m\u00e9s freq\u00fcent: es localitza en la l\u00ednia mitjana del maxil\u00b7lar superior, entre els dos incisius centrals, i \u00e9s responsable d’una proporci\u00f3 important dels casos de diastema (separaci\u00f3 entre els incisius) i de falta d’erupci\u00f3 dels incisius permanents en nens.<\/p>\n\n\n\n

Els paramolars s\u00f3n supernumeraris que apareixen en la zona dels molars, habitualment en posici\u00f3 vestibular o palatina respecte als molars normals.<\/p>\n\n\n\n

Els distomolars (o habitacions molars) es localitzen distal al tercer molar i s\u00f3n els segons m\u00e9s freq\u00fcents despr\u00e9s del mesiodens. Segons la seva morfologia, els supernumeraris poden ser tuberculars (amb forma c\u00f2nica o de tubercle, sovint invertits i impactats), suplementaris (amb morfologia similar a la de la dent normal d’aquesta zona) o odontomes (masses de teixit dental desorganitzat, t\u00e8cnicament considerades malformacions m\u00e9s que dents pr\u00f2piament dites).<\/p>\n\n\n\n

Quins problemes poden causar si no es tracten?<\/h2>\n\n\n\n

Una dent supernumer\u00e0ria no tractat pot generar una cadena de conseq\u00fc\u00e8ncies que afecten a tota la dentici\u00f3 adjacent. La m\u00e9s freq\u00fcent \u00e9s la retenci\u00f3 o erupci\u00f3 ect\u00f2pica de les dents permanents ve\u00efns: el supernumerari ocupa l’espai que hauria d’ocupar la dent normal i impedeix o desvia la seva erupci\u00f3.<\/p>\n\n\n\n

Tamb\u00e9 pot provocar reabsorci\u00f3 radicular de les dents adjacents (el supernumerari exerceix pressi\u00f3 sobre les arrels de les dents ve\u00efnes i les destrueix progressivament), formaci\u00f3 de quistos fol\u00b7liculars al voltant de la seva corona, diastemes persistents que no responen al tractament ortod\u00f2ntic mentre el supernumerari no s’extreu, i apinyament dental per l’ocupaci\u00f3 d’espai en l’arc.<\/p>\n\n\n\n

En casos de supernumeraris erupcionats, la dificultat d’higiene en la zona pot afavorir l’aparici\u00f3 de c\u00e0ries i malaltia periodontal localitzada.<\/p>\n\n\n\n

Com es diagnostiquen les dents supernumer\u00e0ries?<\/h2>\n\n\n\n

El diagn\u00f2stic \u00e9s fonamentalment radiol\u00f2gic. L’ortopantomografia (radiografia panor\u00e0mica) permet identificar la pres\u00e8ncia de supernumeraris en la majoria dels casos i valorar la seva posici\u00f3 aproximada respecte a les dents adjacents.<\/p>\n\n\n\n

No obstant aix\u00f2, per a planificar la cirurgia amb precisi\u00f3, especialment en supernumeraris palatins o en posicions complexes, el CBCT (tomografia computada de feix c\u00f2nic) \u00e9s imprescindible: proporciona una imatge tridimensional que permet determinar amb exactitud la posici\u00f3 del supernumerari en els tres plans de l’espai, la seva relaci\u00f3 amb les arrels de les dents ve\u00efnes i la via d’acc\u00e9s quir\u00fargic m\u00e9s segura.<\/p>\n\n\n\n

El diagn\u00f2stic preco\u00e7, idealment abans dels deu anys en el cas del mesiodens, permet actuar abans que es produeixin les complicacions m\u00e9s greus sobre la dentici\u00f3 permanent.<\/p>\n\n\n\n

Quan i com s’extreu una dent supernumer\u00e0ria?<\/h2>\n\n\n\n

La indicaci\u00f3 d’extracci\u00f3 quir\u00fargica existeix en la majoria dels casos, especialment quan el supernumerari est\u00e0 causant o t\u00e9 potencial de causar alguna de les complicacions descrites. La t\u00e8cnica quir\u00fargica varia en funci\u00f3 de la localitzaci\u00f3, la profunditat de impactaci\u00f3 i la relaci\u00f3 amb les estructures adjacents.<\/p>\n\n\n\n

En supernumeraris superficials o parcialment erupcionats, l’extracci\u00f3 pot realitzar-se sota anest\u00e8sia local de forma relativament senzilla.<\/p>\n\n\n\n

En supernumeraris profundament impactats, en posici\u00f3 palatina o amb relaci\u00f3 estreta amb les arrels de les dents ve\u00efnes, la cirurgia requereix complexitat t\u00e8cnica m\u00e9s gran: obertura d’un penjoll muc\u00f3s, ostectomia (eliminaci\u00f3 d’os per a accedir a la dent) i odontosecci\u00f3 (secci\u00f3 de la dent en fragments per a facilitar la seva extracci\u00f3) quan la posici\u00f3 l’exigeix.<\/p>\n\n\n\n

En Cl\u00ednica Belodonte la planificaci\u00f3 quir\u00fargica de cada cas es realitza sobre el CBCT, la qual cosa permet anticipar les dificultats t\u00e8cniques i minimitzar el risc de mal a les estructures adjacents.<\/p>\n\n\n\n

Qu\u00e8 ocorre despr\u00e9s de l’extracci\u00f3 quir\u00fargica?<\/h2>\n\n\n\n

La recuperaci\u00f3 despr\u00e9s de l’extracci\u00f3 d’una dent supernumer\u00e0ria \u00e9s similar a la de qualsevol cirurgia oral de complexitat equivalent. El postoperatori immediat inclou inflamaci\u00f3, mol\u00e8sties i limitaci\u00f3 funcional durant els primers tres a cinc dies, manejables amb analg\u00e8sia i antiinflamatoris pautats.<\/p>\n\n\n\n

En els casos en qu\u00e8 el supernumerari estava causant retenci\u00f3 d’una dent permanent, l’extracci\u00f3 del supernumerari no garanteix per si sola l’erupci\u00f3 espont\u00e0nia de la dent retinguda: en funci\u00f3 de l’edat del pacient i del temps de retenci\u00f3, pot ser necess\u00e0ria la tracci\u00f3 ortod\u00f2ntica de la dent per a guiar-lo fins a la seva posici\u00f3 correcta en l’arc dental. La coordinaci\u00f3 entre el cirurgi\u00e0 oral i el ortodontista \u00e9s fonamental en aquests casos per a dissenyar el pla de tractament m\u00e9s efica\u00e7.<\/p>\n\n\n\n
