INTRODUCTION: Impaction is defined as the failure of tooth eruption at its correct site in the dental arch, in its normal period of growth. The permanent maxillary canine is the most commonly impacted tooth after third molars, it has a predilection for the oral side with a tendency to be unilateral. It is more common in females. The etiology is unclear: orally impacted canines can be associated with hypoplastic or missing lateral incisors or with aplasia of premolars, presence of supernumerary teeth and mal-positioned third molars. There are many possible surgical techniques to approach impacted canines: early interceptive intervention or late intervention, including extraction, auto-transplantation, surgical exposure of the canine’s crown with open or closed technique and subsequent orthodontic alignment. The choice depends on canine position, associated malocclusion, skill and experience of orthodontist and surgeon, patient compliance. Literature reports that High-Intensity Laser Therapies (HILT) with cutting action on the soft tissues, can also be used for opercolectomy of impacted tooth. MATERIALS AND METHODS: A 13-years-old female referred to the Department of Oral and Maxillo-Facial Sciences, “Sapienza” University of Rome, for an orthodontic examination because of the maxillary primary canines persistence in dental arch. Orthopanoramic X-ray showed osteo- mucosal impaction of both permanent maxillary canines. The family history revealed that patient’s mother had the same orthodontic problem. Cone Beam CT was requested to plan the surgical- orthodontic treatment. Surgical exposure of the impacted canines was performed using a CO 2 laser (Smart US20D®, DEKA-Florence, Italy) and subsequent periodontal wrap application. No orthodontic devices were applied for impacted teeth traction on dental arch. Canines movement towards the dental arch was monitored at 1,4,8,16-weeks post-surgery with photo and intraoral scanner CS3500 (Carestream Dental). When canines crowns were completely erupted on palatal side, the alignment in the arch with indirect bonding technique was performed. RESULTS: Complete dis-impaction of canines crown was obtained in only four months. CONCLUSIONS: As mentioned in Literature, this case confirms that impacted canines exposure with CO 2 laser has advantages if compared with traditional surgery: no bleeding during and after procedure, no need to use sutures and laser bio-stimulating effect allow spontaneous eruption faster than with conventional treatments.
L’inclusione è definita come la mancata comparsa nell’arcata dentaria dell’elemento dentario, durante il suo fisiologico periodo di eruzione. I canini mascellari permanenti sono i più comuni denti che vanno incontro ad inclusione dopo i terzi molari, hanno come predilezione l’inclusione palatale con una tendenza all’inclusione unilaterale. È più comune nelle femmine che nei maschi. L’eziologia non è chiara: i canini inclusi palatali possono essere associati ad ipoplasia o ad agenesia degli incisivi laterali contigui o ad aplasia dei premolari, alla presenza di denti sovrannumerari e disodontiasi dei terzi molari. Vi sono diversi approcci chirurgici per la disinclusione di tali elementi: una terapia chirurgica intercettiva o tardiva, estrazione dell’elemento incluso, l’auto-trapianto, esposizione chirurgica della corona del canino incluso con tecnica aperta o chiusa e successiva trazione in arcata. La scelta dipende, dalla posizione del canino incluso, dalla malocclusione associata, dall’esperienza del chirurgo e dell’ortodontista e dalla compliance del paziente. La letteratura riporta che una terapia laser ad alta intensità (HILT) con azione di taglio sui tessuti molli, può e4ssere usata per creare l’opercolectomia del dente incluso. MATERIALI & METODI Una paziente femmina di anni 13 si è presentata alla nostra osservazione presso il Dipartimento di Odontoiatria e Protesi Dentaria, Sapienza Università di Roma, per una visita ortodontica, poiché persisteva in arcata il canino deciduo. La radiografia Ortopanoramica mostrava un’inclusione osteo-mucosa di entrambi i canini permanenti mascellari. L’anamnesi familiare remota ha messo alla luce che la madre della paziente aveva avuto la stessa problematica. Per il piano terapeutico è stata richiesta una CBCT. L’esposizione chirurgica dei canini inclusi è stata effettuata con CO 2 laser (Smart US20D®, DEKA-Florence, Italy), previa osteotomia e successivamente applicato un impacco parodontale. Nessun dispositivo ortodontico di trazione è stato applicato. Il movimento verso l’arcata dentarie dei canini inclusi è stato monitorato ad 1,4,8,16 settimane dall’intervento chirurgico con foto e scansione intra-orale CS3500 (Carestream Dental). Quando i canini sono erotti completamente sul versante palatale, si è proceduti con all’allineamento in arcata mediante terapia fissa multi-brackets con bandaggio indiretto. RISULTATI In quattro mesi si è ottenuta l’eruzione completa della corona degli elementi inclusi. CONCLUSIONI Come riportato in Letteratura, questo caso conferma che l’esposizione chirurgica del dente incluso con laser CO 2 presenta dei vantaggi se confrontata con la chirurgia tradizionale: nessun sanguinamento durante e dopo l’intervento, nessuna necessità di punti di sutura e l’effetto bio-stimolante della luca laser mostra una eruzione più veloce e spontanea dei trattamenti convenzionali.
