“…[1–4] Mesiodens, defined as a supernumerary tooth located between the 2 central incisors, is the most commonly impacted tooth and frequently found in the maxilla and in the permanent dentition with a prevalence of 0.15% to 1.9% in the general population. [5–7] …”

“…Hyperdontia or supernumerary teeth are those that exceed the normal dental formula and can be found in almost any region of the dental arch, which are encountered more frequently in maxilla than in mandible, and anteriorly than posteriorly, with a predilection for the maxillary incisor region. [ 1 – 4 ] Mesiodens, defined as a supernumerary tooth located between the 2 central incisors, is the most commonly impacted tooth and frequently found in the maxilla and in the permanent dentition with a prevalence of 0.15% to 1.9% in the general population.

“…Conventional approach for the removal of a deeply impacted mesiodens is accompanied with complications such as permanent teeth injury, supernumerary tooth entering nasal cavity, or maxillary deformity because of mass bone removal. [ 1 , 6 ] Moreover, ANS plays an important role as a bony structure supporting the columella and nasal tip while maintaining the individual nasolabial angle (NLA). [ 9 ] Piezosurgery, as a promising, meticulous and soft tissue-sparing system, has proven to be an effective tool for cutting bone without encountering necrosis from overheating and damaging soft tissues.…”

The aim of this study was to introduce a novel method of mesiodens extraction using a vascularized pedicled bone flap by piezosurgery and to compare the differences between a computer-aided design surgical guide template and free-hand operation.A total of 8 patients with mesiodens, 4 with a surgical guide (group I), and 4 without it (group II) were included in the study. The surgical design was to construct a trapdoor pedicle on the superior mucoperiosteal attachment with application of piezosurgery. The bone lid was repositioned after mesiodens extraction. Group I patients underwent surgeries based on the preoperative planning with surgical guide templates, while group II patients underwent free-hand operation. The outcome variables were success rate, intraoperative time, anterior nasal spine (ANS) position, changes of nasolabial angle (NLA), and major complications. Data from the 2 groups were compared by SPSS 17.0, using Wilcoxon test.The operative time was significantly shorter in group I patients. All the mesiodentes were extracted successfully and no obvious differences of preoperative and postoperative ANS position and NLA value were found in both groups. The patients were all recovered uneventfully.Surgical guide templates can enhance clinical accuracy and reduce operative time by facilitating accurate osteotomies.

“…However, given their special anatomical location, their extraction is challenging due to the need to remove large amounts of bone during surgery. In addition, surgery-induced trauma may cause unnecessary complications, further affecting the effectiveness of orthodontic treatments [4]. Three-dimensional (3D) positioning guides have helped reduce trauma during impacted supernumerary tooth extraction [5].…”

Impacted supernumerary teeth are defined as the presence of one or more teeth in a patient's upper and lower jaws in addition to the normal number of teeth in the dental arch. It has an incidence rate of approximately 1%-14% and more frequently occurs in males than females, may be single or multiple, unilateral or bilateral, erupted or impacted. In this article, we describe the case of a patient with two supernumerary teeth between the roots of the mandibular second premolar and the first molar, which influenced the effectiveness of the first orthodontic treatment. The special anatomical position of the complex supernumerary teeth made tooth extraction challenging. Given the higher risk status of surgery, we implemented a novel tooth extracting technique for this patient. Thus, in this study, we describe a case of minimally invasive extraction of bilateral mandibular impacted supernumerary teeth using a digital 3D positioning guide plate.
