Serial Extraction: Is It a Panacea for Crowded Arches?
Review article Annals and Essences of Dentistry SERIAL EXTRACTION: IS IT A PANACEA FOR CROWDED ARCHES? * Radhika Chopra * Senior Lecturer, Karnavati School of Dentistry, Ghandhinagar ABSTRACT Serial Extraction or the guidance of eruption is an age old procedure to correct crowded arches and is still used in routine dental practice. But the efficacy of this procedure has always been controversial and it requires very precise clinical skill for a favorable outcome. This article presents a review regarding the proper selection of cases for serial extraction, its limitations and various adjuncts that are required to get good results. INTRODUCTION: Robert Bunon,23 in his Essay on Diseases of Intercepting certain forms of malocculsion Teeth, published in 1743, made the first reference with a preliminary program of serial extraction has a to early extractions. legitimate place in orthodontics.

Serial extraction is based on the premise Strangely their early recommendations that in certain cases the orthodontist is confronted were ignored for nearly two centuries.

Serial Extraction
أ. د. أكرم فيصل الحويزي 5th Year Lec. No. 11 SERIAL EXTRACTION Serial extraction involves the timed extraction of primary and, ultimately, permanent teeth to relieve severe crowding and to guide the erupting permanent teeth into a more favorable position. It is better termed it ‘Guidance of Eruption’ or ‘Guidance of Occlusion’. Commonly at 7-8 years of age the maxillary and mandibular central incisors have erupted, but there is inadequate space in anterior segments to allow normal eruption and positioning of lateral incisors. In some cases, mandibular lateral incisors have already erupted but they are usually lingually positioned and rotated. The same is with the maxillary lateral incisors. The orthodontist has four option: Wait for growth to provide more space and re-evaluate later. Expansion of the dental arch. However, the stability of expansion may be compromised by the insufficient alveolar basal bone. Cement a transpalatal or lingual bar to preserve the Leeway space for later on. Serial extraction can reduce crowding and irregularity during the mixed dentition. HISTORY Bunon (1743) made the first reference to the extraction of deciduous teeth to achieve a better alignment of permanent teeth. In 1929, Kjellgren of Sweden first used the term ‘serial extraction’. In the 1940s, the technique was popularised in the United States by Nance who is known as the Father of serial extraction. It was advocated originally as a method to treat severe crowding by their own dentists without or with only minimal use of appliance therapy, thus minimizing demands upon the orthodontic service. Although serial extraction makes later comprehensive treatment easier and often quicker, by itself it almost never results in ideal tooth position or closure of excess space. -
Serial Extraction: a Review
8902 Indian Journal of Forensic Medicine & Toxicology, October-December 2020, Vol. 14, No. 4 Serial Extraction: A Review Sulagna Pradhan1, Sushant Mohanty2, Sonu Acharya3, Sonali Bhuyan1, Mrinali Shukla1 1Post Graduate Trainee, 2Professor & Head, 3Professor, Department of Paediatric and Preventive Dentistry, Institute of Dental Sciences, Siksha O Anusandhan (Deemed to be University), Bhubaneswar 751003,Odisha, India Abstract Serial extraction or eruption with guidance is a pre-planned, premature extraction of certain primary teeth to create space that has been compromised. It is followed by the extraction of certain permanent teeth to maintain the proper proportion of tooth size and dentoalveolar bone space. However, this procedure is challenging as it requires in-depth clinical knowledge and skill. This article provides essential insights to the clinicians to identify and categorize the cases meticulously for serial extraction, apply both theoretical and practical aspects of growth and development, and diagnose the alarming signs of primary crowding in early mixed dentition period.

Hence, it is crucial the primary canines should be stripped or removed to enlarge the basal bone, so that all the teeth get proper to accommodate the lateral incisors followed by the accommodation. -

Relapse of Anterior Crowding in Patients Treated with Extraction and Nonextraction of Premolars
ORIGINAL ARTICLE Relapse of anterior crowding in patients treated with extraction and nonextraction of premolars Aslıhan Ertan Erdinc,a Ram S. Nanda,b and Erdal Is¸ ıksalc Izmir, Turkey, and Oklahoma City, Okla Introduction: The purpose of this study was to evaluate long-term stability of incisor crowding in orthodontic patients treated with and without premolar extractions. Methods: Dental casts and cephalometric records of 98 patients were evaluated before treatment (T1), at posttreatment (T2), and at postretention (T3). Half of the patients had been treated with extractions, and half were treated nonextraction. Results: Irregularity, as measured by the irregularity index, decreased 5.51 mm in the extraction group and 2.38 mm in the nonextraction group. Mandibular incisor irregularity increased 0.97 mm in the extraction group and 0.99 mm in the nonextraction group, respectively, in the postretention period. Maxillary incisor irregularity relapse was smaller than mandibular incisor relapse for both groups. Intercanine width expanded during treatment. At T3, mandibular intercanine width decreased in both groups, but the differences were not statistically significant. At T3, intermolar width was stable, arch depth decreased, overbite and overjet slightly increased, SN mandibular plane angle decreased, and incisor positions in both groups tended to return to T1 values. Clinically acceptable stability was obtained. Conclusions: With the exception of the interincisal angle, no statistically significant differences were recorded between the extraction and nonextraction groups from T2 to T3. No statistically significant correlations were found between any variables studied and mandibular incisor irregularity at T1, T2, and T3. (Am J Orthod Dentofacial Orthop 2006;129:775-84) major goal of orthodontic treatment is to arises as to which treatment procedure is most helpful achieve long-term stability of posttreatment in achieving long-term stability. -
