Early Premolar Extraction: An Uncommon but Very Effective Treatment Option
Journal Title: Biomedical Journal of Scientific & Technical Research (BJSTR) - Year 2017, Vol 1, Issue 3
Abstract
Introduction The terminology “serial extraction” in Orthodontics was first described in the late 1920’s when Kjellgren [1] decided to plan the extraction of certain deciduous and permanent teeth at early stages of the dentition development. Since the extractions are under taken at the transitional dentition. This type of treatment is defined as “Early Treatment” in Orthodontics [2]. The main indication for this treatment approach is for patients with severe crowding caused by tooth size arch discrepancies [3,4]. In other words, when maxillary and/or mandibular arches cannot accommodate teeth, extraction becomes an interesting option. Although this treatment option has been used for almost a century in the contemporary orthodontics it’s indication is very specific. Since it’s an irreversible approach (permanent teeth are early extracted) the clinician should carefully diagnosis the case before selecting this option. In addition, as time passed by, orthodontics specialty has dramatically evolved and developed several options to gain space instead of extracting teeth. On the other hand, the idea to early extract permanent teeth continues to be an interesting treatment option in clinical orthodontics mainly in severely crowded patients. The aim of this paper is to present a case report of a ten-year-old male patient who presented severe crowding and treatment option was to extract four first premolars at early stages of the dentition development.A ten-year-old female with no notable medical history presented to my orthodontic clinic with the chief complaint, as reported by her mother that she “I have some spacing in my front teeth”. The intraoral examination showed that the patient was in the final phase of the transitional dentition with a Class I molar relationship, over jet and over jet bite within normal limits and a tooth-size discrepancy of 11 mm in the mandibular arch and 13 mm in the maxillary arch (Figure 1).An analysis of the panoramic radiograph indicated the presence of all permanent teeth and the most important finding was that the maxillary canines were positioned very high in the alveolar bone close the lateral incisors apexes (Figure 2). Interceptive orthodontic treatment was planned to correct the crowding by means of permanent teeth extraction. After discussing the advantages and disadvantages of this treatment with the parents, patient was referred for extraction of four first premolars.
