Eruption Of Impacted Teeth Research Articles

Can we predict eruption of impacted teeth associated with dentigerous cysts in children?

Amaç: Bu çalışmanın amacı çocuklarda dentigeröz kist (DK) nedeni ile gömülü kalan dişlerin, marsüpyalizasyon sonrası sürmesini incelemek ve hangi faktörlerin ilişkili dişlerin sürmesinde belirleyici olduğunu araştırmaktır.Gereç ve Yöntem: DK nedeni ile gömülü kalan daimi dişleri olan ve marsüpyalizasyon yapılan 63 çocuk hastanın kayıtları, sürmeyi etkileyebilecek faktörler açısından değerlendirildi. Hastalar dişlerin sürmesi ve sürmemesine göre iki grupta incelendi. Çalışmada sürmeyi etkileyebilecek faktörler; yaş, cinsiyet, dişin derinliği, dişin açısı, kök gelişimi, dişin sürmesi gereken boşluk ve dişin meziyo-distal boyutu arasındaki oran, kistin boyutu ve obturatör/yer tutucu kullanımı olarak belirlendi.Bulgular: Diş derinliği ortalaması sürmeyen grupta 11,1±3,2 mm, süren grupta 8,1±3,9 mm olarak bulunurken; gömülü dişlerin açı ortalaması sürmeyen grupta 41,5±22,6 süren grupta 27,9±21,3 derece olarak bulundu. Lojistik regresyon analizinde de bu iki faktör dişlerin kendiliğinden sürmemesi ile ilişkiliydi. Sonuç: Tedavi kararı verilirken, DK ile ilişkili gömülü dişlerin marsüpyalizasyon sonrası sürüp sürmeyeceğinin tahmin edilmesinde dişin derinliği ve açısı önemli faktörler olarak değerlendirilebilir. Ayrıca sürmesi geciken daimi dişlerin varlığında DK tespit edilmesi durumunda tedaviye gömülü dişlerin fizyolojik sürme zamanlarından önce başlanması, normal sürme zamanı ile tedaviye başlama yaşı arasında çok uzun süre yoksa obtüratör/yer tutucu yapılmaması tavsiye edilebilir.

Eruption of Impacted Teeth after Alveolar Bone Graft in Cleft Lip and Palate Region

This study aimed to assess the eruption of impacted teeth in cleft lip and/or palate (CLP) after alveolar bone graft. Research was carried out through a cross-sectional study at the Craniofacial Rehabilitation Center of the University General Hospital of the University of Cuiaba, Mato Grosso, Brazil. Variables related to cleft, cleft side, gender, age, laterality of cleft, impacted teeth, and orthodontic traction were analyzed. Forty-two patients treated at the institution from 2004 to 2011 were recruited. There were 54.76% males and 45.24% females. The age group between 9 and 11 years was most affected in 59.53% of cases. The unilateral cleft was the most prevalent (85.71%). A total of 57 impacted teeth were observed. Maxillary canine was the most prevalent impacted teeth (97.61%) and more frequent in transforamen incisor cleft (TIC) (76.3%). The orthodontic traction was needed in both maxillary canines and lateral incisor impacted teeth, 64.3 and 35.7% respectively. The orthodontic traction was needed only in TIC (p = 0.0101). The canine teeth were the most prevalent, mainly related to the TIC and all impacted teeth erupted spontaneously in the preforamen incisor cleft (PIC) after placement of the bone graft. There was spontaneous eruption of impacted teeth after secondary alveolar bone graft in CLP.

Eruption of Impacted Teeth in Cleft Lip and Palate Patients following Alveolar Bone Graft

This study aimed to assess the eruption of impacted teeth in cleft lip and/or palate (CLP) after alveolar bone graft. Research was carried out through a cross-sectional study at the Craniofacial Rehabilitation Center of the University General Hospital of the University of Cuiabá, Mato Grosso, Brazil. Variables related to cleft, cleft side, gender, age, laterality of cleft, impacted teeth, and orthodontic traction were analyzed. Forty-two patients treated at the institution from 2004 to 2011 had their charts retrospectively reviewed. They were 54.7% male and 45.2% female. The group aged 9 to 11 years was most affected, representing 59.5% of cases. A unilateral cleft was the most prevalent craniofacial anomaly (85.7%). A total of 57 impacted teeth were observed. Maxillary canines were the most commonly impacted teeth (97.6%) and the most frequently identified in patients with a transforamen incisor cleft (TIC) (76.3%). Orthodontic traction was required for both impacted maxillary canines and impacted lateral incisors (64.3 and 35.7% respectively). The orthodontic traction was required only in patients with a TIC (p = 0.0101). The canine teeth were the most commonly impacted teeth, found mainly in patients with a TIC. After placement of the alveolar bone graft in patients with a preforamen incisor cleft (PIC), all impacted teeth erupted spontaneously. An impacted tooth can have negative consequences on a patient's quality of life. Thus, a survey evaluating the incidence and prognosis of impacted teeth after an alveolar bone graft for CLP was important.

W Spring for Management of Impacted Teeth

Forced eruption of an impacted tooth necessitates a firm and versatile attachment for force application. The present article describes a simple modification of NiTi closed coil spring called W spring for predictable forced eruption of impacted teeth.

Use of mandibular chin bone for alveolar bone grafting in cleft patients.

BackgroundWe evaluated and compared the outcomes of different ossification processes in patients with alveolar cleft in whom correction was performed using endochondral bone graft or intramembranous bone graft.MethodsThe patients were divided into two groups: the endochondral bone (iliac bone or rib bone) graft group and the intramembranous bone (mandibular bone) graft group. Medical records and radiologic images of patients who underwent alveolar bone grafting due to alveolar cleft were analyzed retrospectively. Through postoperative and follow-up radiologic images, the height of the interdental bone septum was classified into four types based on the highest point of alveolar ridge. Then, the height of the interdental bone septum and the area of the bone graft were evaluated according to the type of bone graft. In addition, the occurrence of complications and the need for an additional bone graft, the result of postoperative orthodontic treatment, and the eruption of impacted teeth were investigated.ResultsThirty patients were included in this study. There was no significant difference in the change of the interdental bone height and the area of the bone graft according to the type of bone. There was no significant difference in the success rate of the surgery according to the type of bone. One patient underwent an additional bone graft surgery during the follow-up period.ConclusionsThe outcomes of alveolar bone grafting were not significantly different according to the type of bone graft. If appropriate to the size of the recipient site, the chin bone is a useful graft material in alveolar cleft, as is the iliac bone.

Clinical and morphological assessment of low frequency ultrasound use in delayed eruption of teeth

Aim. Development of a new method stimulating eruption of impacted teeth, reducing side effects and the term of orthodontic treatment.
 Methods. Considering the high numbers of patients who sought medical aid with delayed eruption of teeth, rational method of low-frequency ultrasound was used for stimulating eruption of impacted teeth. The stimulation process was performed by «SIAZ-EGS Med-Stomo» device, with the oscillation frequency of 26.5 kHz, intensity of 1 W/cm, amplitude of 40-60 μm, a wavelength 0,012 m, developed in Azerbaijan. Clinical and morphological methods, including examination of gingival tissue biopsies from the area where low-frequency ultrasound was applied, were used. After clinical and radiographic examination and identifying the impacted tooth with a favorable location on dental panoramic radiography, if there was a space in the tooth row, the area of the tooth projection at the gum was directly affected by low-frequency ultrasound daily or every other day for 5-10 seconds. An average of 1-5 procedures up to the tooth eruption was performed.
 Results. Microscopy of epithelial cover and stroma proved the absence of inflammation, thickening of outermost layer on the gum surface. Cells of the intermediate layer revealed the intact nucleus, loosening with linear swelling and cell dissociation. Cellular and tissue changes in gingival tissue seen after the treatment with low-frequency ultrasound may indicate the boosting of the impacted teeth eruption due to the syndrome of molecular contusion, improving the microcirculation and loosening the gum tissues.
 Conclusion. The results of comprehensive orthodontic treatment using low-frequency ultrasound ito stimulate the eruption of impacted teeth may be recommended for practical use.

Normal eruption of impacted teeth associated with a dentigerous cyst managed by simple extraction and decompression

Dentigerous cyst is an epithelial-lined cavity that encloses the crown of an unerupted tooth at the cementoenamel junction, can be either developmental or inflammatory in origin. The purpose of this paper was to report of an asymptomatic dentigerous cyst of inflammatory origin in a 7.5-year-old child who was managed by conservative means of a simple extraction, followed by decompression under local anesthesia. After 16 months of follow-up, the cyst was completely ossified, and the displaced premolars were normally erupted in the oral cavity. Similarly, we also noticed rapid root maturation of the cyst involved premolars than the contralateral premolars.

A Creative Spring Design to Force Erupt Labially Impacted Maxillary Canine Using Single Mini Implant

Introduction: Complications to force eruption of impacted teeth may arise from several reasons including ankylosis, dilaceration, and/ or some barriers in the eruption pathway. Treatment time prolongation without obvious clinical progress gradually decreases the patient compliance. In this paper we present a non-conventional method to forced eruption of an impacted maxillary canine. Case Presentation: A 21-year-old girl presented with missing of teeth No 17, 12, 22, 27, 38, 37, 47, 48 and labially impaction of both maxillary canine was prepared for treatment through apically position flap for exposure of the both canines. Using standard edgewise 0.18 appliance and conventional elastic traction the right maxillary canine erupted to its normal position after about 18 months but the other tooth had not responded favorably to this technique. There was no signs of ankylosis, a titanium bone screw was placed in the labial cortical bone and mesial of the malposed canine. A spring is made of 0.017” × 0.025” SS wire with two helixes that delivered about 100 g force and 400 gr.mm activation moment to labial bracket on malposed canine crown. The force exerted on mini implant will be balanced with a force and moment on malposed tooth very similar to type IV Burston classification. After about 5 months the tooth had reached to its final occlusal position. Conclusions: The appliance used for this patient brought the impacted canine into the arch without any more force on the neighbor teeth. Two point contact of the spring arm by bending the wire over the head of the mini implant made it possible to apply buccolingual crown torque.

Cleidocranial dysplasia: maxillary alterations on the transverse plane. Presence of crown-radicular anomalies and multidisciplinary approach of a clinical case.

Cleidocranial Dysplasia (CCD) is a rare inherited autosomal dominant congenital syndrome that occurs in approximately one out of every one million individuals worldwide; it primarily affects bones that undergo intra-membranous ossification, generally the skull and clavicles. Other bones may be affected such as the long bones, spine, pelvis, bones of hands and feet showing hypoplasia of distal phalanges. Indispensable is the role of the gene Runx2, necessary for the differentiation of odontoblasts and osteoblasts; it regulates the expression of many genes related to the development of dental hard tissues. The aim of this study was to appraise the connection between the Cleidocranial Dysplasia and the appearance of skeletal and dental anomalies not much deepen to this day. With particular emphasis, it wants to describe the multidisciplinary therapeutic approach. The patient showed multiple skeletal features of CCD. A distinctive feature was the failed or delayed exfoliation of deciduous dentition and a delayed eruption of permanent teeth. The goal of the treatment is the improvement of both aesthetic and functional aspects. This objective can be achieved through an appropriate multidisciplinary treatment plan that arranges the orthodontic and surgical measures. Because of the involvement of facial bones, the altered mode of tooth eruption and the presence of numerous included supernumerary teeth, CCD is a pathology that all dentists should be familiar with. The patients have small faces compared to the skull and the hypoplasia of maxillary, tear, nasal and zygomatic bones. The orthodontic approach in literature seems to be reduced to the guided eruption of bad-positioned and impacted teeth. Knowledge of the clinical features of CCD allows for the early planning of the procedures necessary to resolve the dental pathologies observed in CCD patients.

No more monkey business with impacted canines

Various treatment mechanics have been created to direct the eruption of impacted teeth, including the application of intra- and interarch forces to some type of attachment on the affected teeth. The present communication describes the use of two simple auxiliaries, the Monkey Hook* and the Kilroy Spring*, for the directed eruption of impacted and/or the correction of severely rotated teeth.

Biocompatibility of gold and stainless steel chains used for forced eruption of impacted teeth – an in vitro investigation

Surgical approaches for the mobilization of impacted teeth involve the use of gold chains to connect the impacted tooth with the orthodontic appliance. In this study we have compared the local effects gold plated stainless steel with stainless steel specimen using an in vitro model of the gingival mucosa and monolayer cultures of cells of the alveolus. Local effects on differentiation, proliferation, and apoptosis and inflammatory response were tested using organotypic cultures of gingival cells. Cytotoxicity was measured by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assays with monolayer cultures of human periodontal cells. The data obtained in this study could not reveal any differences in favor of using gold plated chains during the mobilization of impacted teeth. For patients not suffering from allergies against nickel there might be no rationale to favor gold plated chains, as there are no functional aspects to favor gold plated chains over stainless steel chains.

Management of multiple impacted teeth

An impacted or missing permanent tooth can add significant complications to an otherwise straightforward case. When multiple impacted teeth are present, the case complexity increases further. Developing a treatment sequence, determining appropriate anchorage, and planning and executing sound biomechanics can be a challenge. The following case report illustrates a patient with three retained primary teeth and three impacted permanent canines. After careful treatment planning and extraction of multiple primary teeth;, followed by attempted guided eruption of impacted teeth, the patient finished with a significantly improved functional and aesthetic result.

Electroporation to deliver plasmid DNA into rat dental tissues

Delivery of DNA into the target tissues is an important technique in gene function studies and gene therapy. Surgical treatment of tooth eruption disorders, such as impacted third molars, is a major healthcare cost. Because the dental follicle (DF) is essential for regulating tooth eruption, establishment of local gene transfer protocols is needed to determine the effect of various genes on eruption and to develop gene therapy approaches for inducing the eruption of impacted molars. Plasmids containing lacZ reporter gene were injected into rat mandibles and then electroporated at the designated settings. Mandibles were collected 24 h after electroporation for X-gal staining to evaluate the transfection efficiency. Tissues were collected at various days post-electroporation to determine the expression of the transgene. For the DF, depth of injection and pulse number appear to be important. Six pulses can achieve above 80% transfection of the DF at 50 V or 120 V. For alveolar bone (AB) transfection, voltages are important, with 120 V being optimal. Regarding pulse durations, we determined that durations of 20 and 30 ms achieve the maximum transfection in AB and DF, respectively. The present study demonstrates for the first time the feasibility of electroporation to locally deliver plasmids into dental tissues. Parameters affecting electroporation to deliver plasmids into the dental tissues were optimized. This protocol could be used to deliver short hairpin RNA or genes of interest into the dental tissues to regulate tooth eruption. Thus, it may be possible to develop nonsurgical treatments for inducing the eruption of impacted teeth.

Assisted eruption of impacted teeth into an alveolar bone graft in a patient with cleft lip and palate

Abstract Aims To assist the eruption of impacted upper teeth into an alveolar bone graft in a patient with a unilateral cleft lip and palate. Methods An 8 year-old Thai boy with left unilateral complete cleft lip and palate had the chief complaint of anterior crossbite. He presented with a mild skeletal 3, dental Class III subdivision malocclusion, anterior crossbite, left unilateral posterior crossbite, moderate crowding in the upper arch with impaction of upper the left lateral incisor (tooth 22) and canine (tooth 23). In the first phase of treatment the posterior crossbite was corrected with a removable appliance with a 3-way screw. In the second phase the impacted teeth were surgically exposed, moved into the alveolar bone graft and the teeth aligned with fixed appliances. The upper left lateral incisor was extracted because of its questionable longevity. Results The orthodontic treatment resulted in normal overjet, overbite and an acceptable facial profile. A prosthesis replaced tooth 22. Conclusions Forced eruption of impacted teeth can be carried out successfully in the cleft patients after an appropriate treatment plan has been formulated and following preparation of alveolar bone graft in the cleft site.

Surgical outcome following exposure and bonding of impacted maxillary canines

Background: Forced orthodontic eruption of impacted teeth with orthodontic traction is a widely used technique. This study evaluates the outcome of exposure and bonding of impacted canine teeth in both palatal and labial positions.

Treatment of a Patient with Multiple Impacted Teeth

An impacted or missing permanent tooth can add significant complications to an otherwise straightforward case. When multiple impacted teeth are present, the case complexity increases further. Developing a treatment sequence, determining appropriate anchorage, and planning and executing sound biomechanics can be a challenge. The following case report illustrates a patient reportedly diagnosed with mild scleroderma as an adolescent. He presented for orthodontic treatment as an adult with multiple retained primary teeth and multiple impacted teeth. Diagnosis, treatment planning, and various methods of managing guided eruption of impacted teeth will be discussed. Following orthodontic treatment that required extraction of multiple primary and permanent teeth as well as exposure and ligation of multiple permanent teeth by an oral surgeon, the patient finished with a significantly improved functional and esthetic result.

Postoperative prognosis of unerupted teeth after removal of supernumerary teeth or odontomas

Impacted teeth do not always erupt spontaneously after removal of supernumerary teeth or odontomas. The purpose of this study was to examine the effect of several variables on eruption of impacted teeth in children with supernumeraries or odontomas. The sample consisted of 53 patients with 69 impacted teeth; the supernumeraries or odontomas were removed without other interventions. The patients were identified retrospectively and followed until the impacted teeth erupted to their correct positions or until orthodontic traction was started. Loss of space, a second surgical procedure, a third surgical procedure, and orthodontic treatment were recorded in 77.6%, 53.8%, 9.4%, and 85% of the patients, respectively. Spontaneous eruption occurred in 83%, 75%, 46%, 19%, and 32% of the impacted teeth with normal and small size superlative, conical, tuberculated, and odontoma forms, respectively. In the univariate analysis, spontaneous eruption correlated with apex distance of the impacted tooth relative to its estimated position (P <.001), extent of vertical impaction (P <.001), obstacle form (P <.019), stage of root development of supernumerary tooth (P = .006), angle of impaction relative to the midline (P = .015), and time of surgery (P = .05). In the multivariate logistic regression analysis, higher distraction of the apex of the impacted tooth relative to its estimated correct position and the obstacle form (tuberculated and odontomas) were independently associated with impediment of spontaneous eruption (P = .03 and P = .04, respectively). Spontaneous eruption of impacted teeth correlated mostly with lower distraction of the impacted tooth apex and obstacle form (conical and superlative). Immediate orthodontic traction is recommended concomitantly with the first surgery to remove supernumerary teeth.

Periodontal concerns associated with the orthodontic treatment of impacted teeth

Impacted teeth are common and are often treated with orthodontic eruption, but periodontal problems associated with the process can evade detection. Profound destruction of the periodontium of an impacted tooth or adjacent teeth can occur. This case report describes the orthodontic eruption of 4 impacted canines in a 19-year-old woman. An open surgical approach was used. Within 6 months of treatment, the maxillary right canine and the lateral incisor experienced severe periodontal destruction, resulting in questionable prognoses for the teeth. Plaque control, periodontal architecture, and subgingival microflora were examined as local etiologic factors of periodontal destruction associated with orthodontic eruption of impacted teeth. Plaque control measures were evaluated, and the consequences of orthodontic tooth movement in the presence of inadequate plaque control were considered. Areas of periodontal architecture made vulnerable by the surgical exposure of the impacted teeth were identified, and the effect of orthodontic force on the periodontium was explored. An increase in putative periopathogens in the subgingival microflora after orthodontic appliance placement was observed. Microbiologic monitoring for pathologic levels of periopathogens and antibiotic therapy were considered. Orthodontic treatment of impacted teeth might require additional professional and personal plaque control measures, 3-dimensional diagnostic imaging, and control of putative periopathogens to preserve the health of the periodontium.
