Supernumerary Tooth Extraction with Intranasal Approach: A Case Report

“Treat All with All” – A Multidisciplinary Approach for an Unusual Case Scenario

Impaction of teeth is more common and widespread. Multiple impacted permanent teeth are usuallyrelated to syndromes, metabolic and hormonal disorders. However, in non-syndromic cases impaction ofmultiple teeth is rare. In this report, a case of A 23-years-old male patient with missing upper front teethand irregularly placed lower front teeth, difficulty in speech and mastication. physical examination wasnot suggestive of any syndromes. On Extraoral examination the patient presented with a concave profile,competent lips, shallow Mento-labial sulcus. On clinical and radiographic examination revealed Angle’sclass III malocclusion on class III skeletal base, with impacted 13,12,11 and 24, anterior cross bite, rotationof 32,33,35,42,44, and horizontal growth pattern. Extraction of supernumerary teeth was carried out in allthe quadrants and PEA 0.22 ROTH appliance was used to align the arches. Bi-jaw surgery with mandibularset back with bilateral split sagittal osteotomy and maxillary advancement with Le Fort I was done to attainideal overjet and overbite.The objective of this report is to increase awareness of such cases especially in the absence of hereditary/genetic/metabolic factors usually inherent in such scenarios. The patient management in such cases needs tobe planned all with all multidisciplinary approach.

A new supernumerary tooth occurring in the same region during follow-up after supernumerary tooth extraction: A case report

A supernumerary tooth (ST) is often detected in the childhood and a surgical approach is usually indicated for its management. Some cases may require orthodontic treatment after extraction; hence, a long-term follow-up is important. A 4-year-and-11-month-old Japanese boy was referred to our hospital for dental caries treatment. A radiographic examination at 5 years and 5 months revealed an ST near the maxillary left primary central incisor, which was later extracted. One year and 6 months after extraction, a metachronous new ST in the same region was detected. We highlight the importance of a regular radiographic examination after ST extraction.

Spontaneous eruption of impacted maxillary incisors after surgical extraction of supernumerary teeth: a systematic review and meta-analysis.

To evaluate the spontaneous eruption potential of impacted human permanent teeth localized in the anterior part of the maxilla, after the surgical extraction of obstacles in their eruption pathway, by means of a systematic review and meta-analysis. A systematic literature search was carried out to locate studies reporting on the percentage of anterior permanent teeth erupting after surgical removal of the obstacle, without other interventions. Eruption potential of impacted teeth was calculated using a random-effects meta-analysis. Information about the sex proportion, follow-up duration, age and years during which the study was carried out was used for subgroup analyses. A total of twelve studies were included, with a total sample size of 960 cases and a follow-up period of up to 36months. The results show that more than 65.5% of impacted teeth erupt spontaneously following surgical extraction of the obstacle, with an odds ratio of 4 (95% CI 1.9, 8.2) (p < 0.001) favouring spontaneous eruption. When faced with an impacted maxillary anterior tooth, surgical extraction of the obstacle can lead to spontaneous eruption of the impacted tooth in the majority of cases, with better success with a longer follow-up for up to 3years. Based on the present meta-analysis, clinical recommendation would be to surgically remove the obstacle impeding the eruption of a maxillary anterior permanent tooth and wait for the eruption of the tooth for a period of 12-36months, depending on the age of the patient.

Validation of a three-dimensional printed model for training of surgical extraction of supernumerary teeth.

This study aimed to validate a three-dimensional (3D) printed model to provide training for supernumerary teeth (SNTs) extraction. Each of the 30 participants, grouped as experienced and without experience, conducted two identically simulated surgeries on a 3D-printed replica of human mixed dentition with a SNT. The surgery time, area of bony window and volume of removed material were measured; subsequently, responses to a five-item questionnaire were recorded. The collected data were statistically analysed. The surgery time was 228.37±141.53seconds and 125.47±53.03seconds in the first and second surgery, respectively. The training significantly decreased the surgery time in the participants without experience (P=.000). However, there were no significant differences in the area of window opening (P=.271) and volume of removed material between the two surgeries (P=.075). The participants who perceived educational benefits accounted for more than 60% of the respondents for every question. Participants without experience in SNT extraction showed a tendency to rate a higher score than did those with experience. A 3D-printed model for surgical extraction of a SNT can improve surgical skill and, especially, shorten the learning curve in beginners.

Complications associated with specific characteristics of supernumerary teeth.

The purpose of this study was to identify the characteristics of supernumerary teeth, analyze the associated complications, and to present new clinical knowledge on surgical interventions for supernumerary teeth. This retrospective cohort study was based on the medical records and radiographic records of patients who underwent surgical extraction of supernumerary teeth. The relationships among the patient's age, gender, anatomic features of supernumerary teeth, and presence and type of complications (i.e., spacing, rotation, delayed eruption of the adjacent tooth, cyst formation.) were investigated. The groups were compared by using the Mann-Whitney U test, the Kolmogorov-Smirnov test, and multiple logistic regression analysis (P < .05). The study population consisted of 705 participants who underwent extraction for 1036 supernumerary teeth. The mean age of the participants was 11.5 years, and 73.5% of the participants were males. The complication rate was 55.6%. Variables associated with an increased risk of complications were the patient's age, dentition, tuberculate shape, and horizontal direction of eruption (P < .05). An increase in the patient's age or abnormalities in the shape and direction of eruption of supernumerary teeth was associated with complications. These parameters should be considered while formulating the treatment plan.

Feasibility of a 3D Surgical Guide Technique for Impacted Supernumerary Tooth Extraction: A Pilot Study with 3D Printed Simulation Models

This study aimed to evaluate the feasibility of a 3-dimensional (3D) planned surgical guide technique designed for impacted supernumerary teeth (STs) extraction using 3D printed simulation models. In total, 17 participants from two university hospitals were recruited. Each participant performed surgery with both the conventional and surgical guide techniques. The following parameters were evaluated: (1) The time required for ST extraction, (2) the area of the window opening, and (3) the volume of the material removed. Time required for ST extraction was 213.65 ± 167.45 sec and 114.76 ± 42.87 sec in the conventional and surgical guide techniques, respectively, with significant differences (p = 0.028). The required area of the window opening was 48.10 ± 9.44 mm2 and 45.90 ± 8.17 mm2, respectively, in the conventional and surgical guide techniques, with no significant differences (p &gt; 0.05). The required volume of the material removed was 121.65 ± 43.69 mm3 and 99.12 ± 17.88 mm3 in the conventional and surgical guide techniques, respectively, with significant differences (p = 0.031). The 3D planned surgical guide technique was effective for impacted ST extraction. Within the limits of this study, the surgical guide technique allows us to accomplish minimally invasive surgery within a shorter duration.

Orthodontic Management of Maxillary Canine-first Premolar Transposition by Unilateral Extraction

Introduction: Transposition is an extreme and unique form of ectopic eruption. Orthodontic correction of transposed teeth in permanent dentition comprises the following treatment options: teeth alignment in the transposed position, orthodontic tooth movement into correct teeth order, or extraction on one of the transposed teeth followed by orthodontic correction. Case report: A 20-years-old male presented severe crowding and dental midline shift on both arches, followed by complete transposition of maxillary left canine – first premolar. A supernumerary tooth was also revealed between maxillary lateral and first premolar on the left side. The patient was treated with a pre-adjusted edgewise fixed appliance system. Extraction of supernumerary tooth and unilateral first premolars on the left side were performed to relieve crowding and to achieve stable occlusion. Improvement of smile aesthetic, correction of midline shift, and also an ideal class I of canine and posterior interdigitation were achieved after 22 months of treatment. Conclusion: Definitive treatment of transposition depends on the occlusion, degree of crowding, aesthetics, root position of the transposed teeth, and specific needs of the patient. Care must be taken to prevent midline shift and development of arch asymmetry during orthodontic correction of transposition involving unilateral extraction.

Osteo-regeneration personalized for children by rapid maxillary expansion: an imaging study based on synchrotron radiation microtomography

BackgroundPersonalized maxillary expansion procedure has been proposed to correct maxillary transversal deficiency; different protocols of stem cell activation have been suggested and rapid maxillary expansion (RME) is the most commonly used among clinicians. The present study aimed to quantify in three-dimensions (3D) the osteo-regeneration of the midpalatal suture in children submitted to RME.MethodsThree patients (mean age 8.3 ± 0.9 years) were enrolled in the study to preform biopsy of midpalatal suture. Two patients (subjects 1 and 2) were subjected to RME before biopsy. The third patient did not need maxillary expansion treatment and was enrolled as control (subject 3). Midpalatal suture samples were harvested 7 days after RME in subject 1, and 30 days after RME in subject 2. The samples were harvested with the clinical aim to remove bone for the supernumerary tooth extraction. When possible, maxillary suture and bone margins were both included in the sample. All the biopsies were evaluated by complementary imaging techniques, namely Synchrotron Radiation-based X-ray microtomography (microCT) and comparative light and electron microscopy.ResultsIn agreement with microscopy, it was detected by microCT a relevant amount of newly formed bone both 7 days and 30 days after RME, with bone growth and a progressive mineralization, even if still immature respect to the control, also 30 days after RME. Interestingly, the microCT showed that the new bone was strongly connected and cross-linked, without a preferential orientation perpendicular to the suture’s long axis (previously hypothesized by histology), but with well-organized and rather isotropic 3D trabeculae.ConclusionsThe microCT imaging revealed, for the first time to the authors’ knowledge, the 3D bone regeneration in children submitted to RME.

Clinical retrospective study of navigation guided impacted maxillary supernumerary tooth extraction

Objective: To analyze the efficiency and safety of navigation guided extraction of impacted supernumerary tooth. Methods: Twenty-five cases of navigation guided supernumerary tooth extraction and 25 cases of non-navigation guided supernumerary tooth extraction (control group) were included in the study. Each group had 3 cases with one impacted supernumerary tooth and 22 cases with two impacted teeth. Results: Preoperative navigation system designing time was (45.0±8.0) min in average. Navigation system installation time was (15.0±2.8) min. The average operation time was (0.64±0.08) hour in navigation group and (0.91±0.09) hour in control group. Conclusions: Navigation guided extraction of impacted supernumerary tooth takes less time for operation but more time for the preoperative navigation system design.

Eruption cyst due to supernumerary tooth-a chance occurrence

Eruption cyst is a benign cyst associated with a primary or permanent tooth in its soft tissue phase after erupting through the bone. This case report documents a rare case in which the presence of supernumerary tooth hindered the normal eruption of permanent right maxillary central incisor subsequently the deficient space resulted in the formation of eruption cyst. The treatment included the extraction of supernumerary tooth followed by the surgical exposure of crown of the tooth associated with the eruption cyst. The present case report illustrates that the treatment of choice must be case specific with adequate analysis of clinical and radiographic findings and should be managed appropriately in order to minimize complications to the developing and erupting tooth.

Mesiodens en posición inusual: reporte de un caso

Los dientes supernumerarios son alteraciones medianamente frecuentes que aparecen en cualquier área de los arcos dentales y pueden afectar a cualquier órgano dentario anterior, también llamado mesiodens. Esta alteración clínicamente presenta erupción retardada e inclusión de dientes permanentes, apiñamiento, diastemas, mal oclusión y en casos más complejos se pueden encontrar a nivel de piso de fosas nasales o incluídos en el seno maxilar, la mayoría de veces son asintomáticos. Las radiografías panorámica oclusal, peri apical o tomografía computarizada (TC) como ayudas complementarias son de gran utilidad para un buen diagnóstico y ubicación precisa. El tratamiento depende del caso, extracción en casos necesarios o realizar un seguimiento radiográfico. Se presenta un caso clínico del servicio de cirugía oral en la clínica odontológica de la Fundación Hospital Universitario Metropolitano, un paciente de 26 años de edad, masculino con impresión diagnostica de diente supernumerario mesiodens con intento previo de extracción sin éxito. Clínicamente no se evidencian signos de la presencia del mesiodens. Radiografías como ortopantografia, oclusal periapical no permite una posición exacta, por esto se recurre a una tomografía segmentaria logrando mejor ubicación del DS, permitiendo un plan de tratamiento ideal.

Piezoelectric ultrasonic bone surgery system in the extraction surgery of supernumerary teeth

IntroductionThe anterior maxillary region is a common site for supernumerary teeth. The aim of this study was to compare the use of piezoelectric ultrasonic bone surgery for the extraction of supernumerary teeth and the use of traditional method using bone chisels. Methods60 patients with supernumerary anterior maxillary teeth were considered in this study. They were randomly divided into two groups: 1) the control group, in which the supernumerary teeth were extracted using the traditional bone chisels method; 2) the experimental group, in which the supernumerary teeth were extracted using a piezoelectric ultrasonic bone surgery system. The operative time, amount of bleeding and post-operative pain were quantified and compared; in addition, the post-operative swelling was evaluated. ResultsWe observed a significant decrease (P < 0.01) in the amount of bleeding and post-operative pain in the experimental group respect to the control group; but the operative time was significantly increased (P < 0.01) with the use of piezoelectric system. In addition, post-operative swelling resolved more quickly in the experimental group. ConclusionAlthough the operative time for the extraction of the maxillary anterior supernumerary teeth was longer using the piezoelectric ultrasonic bone surgery system, the amount of bleeding and the post-operative complications were less, so this system could be considered an appropriate surgical method for the extraction of supernumerary teeth.

�M� Mechanics for the Management of Maxillary Midline Diastema

Maxillary midline diastema is commonly occurring malocclusion. Variety of treatment modalities are suggested for the management of diastema. This article presents a case report in which 14-year-old female patient was treated for the maxillary midline diastema of size 3 mm after extraction of supernumerary tooth between upper central incisors. The index of orthodontic treatment was mild (Grade 2). MBT 0.022'' brackets were bonded on the maxillary central incisors. M spring was fabricated, activated and ligated initially with round archwire followed by rectangular archwire. Successful closure of diastema was seen with total treatment duration of 4 months. This method is efficient, effective, require less inventory. This saves precious chairside time of orthodontics and reduces treatment duration as well.

Abordagem Cirúrgica de Dente Supranumerário (Mesiodens) na Região Palatina: Caso Clínico

Supernumerary teeth can be found during permanent dentition more often than at the deciduous one, with maxilla been the most committed arch and more often in man than in women. The mesiodens are the most common dental anomalies, affecting from 0.15% to 3.8% of the population. Its etiology in not fully understood, although most authors support the hyperactivity of the dental lamina theory. The panoramic, oclusal and periapical x-rays are an important and essential way to diagnosis possible supernumerary teeth, with the majority of such teeth been impacted and asymptomatic. Due to its high incidence, the dentist must be able to diagnosis and to carry out the most adequate treatment during the appropriate period, reducing surgery time, indicating a possible orthodontic treatment and preventing future complications. This paper has the aim to show a case of a supernumerary tooth extraction classified as mesiodens.

A retrospective evaluation of the eruption of impacted permanent incisors after extraction of supernumerary teeth

Delayed eruption of teeth may be caused by the presence of one or more supernumerary teeth. The purpose of this study was to evaluate findings, predisposing factors and differentiate different techniques used that affect the outcome following removal of supernumerary teeth. A comprehensive literature review was also undertaken. A longitudinal retrospective study was carried out at the Royal Liverpool Children's Hospital. A total of 120 patients were identified from the general anesthesia records that had supernumeraries extracted. Only 43 cases had delayed eruption of teeth caused by supernumeraries. The pre and post extraction record data collected were the gender, radiographic assessment, position of the supernumerary, age at time of referral and extraction of the supernumerary, age at time of eruption of the impacted tooth and the orthodontic and surgical management. The mean age of referral was 9.1 years with a male to female ratio of 4.4:1. There was a greater predilection for supernumeraries to be on the left side and be positioned palatally. Tuberculate type supernumeraries were the most frequent followed by the conical type. Spontaneous eruption of the impacted tooth occurred in 49% of cases. Eruption of the impacted tooth within eighteen months following removal of the supernumerary was observed in 91% of cases. The chronological age and space availability were the two factors that were critical in determining if eruption was spontaneous following removal of the supernumerary. The findings of this study reiterates the fact that given early referral, sufficient space and time, the majority of teeth prevented from erupting by a supernumerary tooth would erupt spontaneously following removal of the supernumerary alone. Randomized multi-centre prospective studies are suggested.
