ABSTRACT Lower incisor extraction in orthodontic treatment was very rare modality of orthodontic treatment because there are few patients who meet the standards for such treatment. Proper diagnosis and treatment planning should be done to achieve good occlusion and facial esthetics. Criteria for lower incisor extraction included degree of crowding, tooth size discrepancy, pathologic condition, vertical overbite, sagittal incisal relationship, skeletal growth pattern and age of the patient. This article comprises of a case of class I malocclusion treated with lower incisor extraction, with comprehensive analysis, diagnosis and treatment planning, treatment results were satisfactory. Clinical significance Mandibular incisor extraction can be an effective treatment option in borderline cases with mild crowding in lower arch. Minimal alteration of mandibular arch form is key factor for success and stable results. How to cite this article Raju DS, Veereshi AS, Naidu DL, Raju BHVR, Goel M, Maheshwari A.

Mandibular incisor extraction for orthodontic treatment is considered an unusual treatment option because of the limited number of patients that meet the criteria for such treatment. Accurate diagnosis and treatment planning is essential to achieve the desired results. Adult orthodontic patients are increasingly motivated by esthetic considerations and reject the idea of conventional fixed appliances. In recent years, Invisalign appliances have gained tremendous attention for orthodontic treatment of adult patients to meet their esthetic demands. In this case report, a case of Class I malocclusion was treated with mandibular incisor extraction using the Invisalign appliance system. Successful tooth alignment of both arches was achieved. The use of Invisalign appliance is an effective treatment option in adult patients with Class I malocclusion that requires incisor extraction due to moderate to severe mandibular anterior crowding.

Index Index

An Index has been developed to assess the severity of dentofacial anomalies. The index values reflect the severity of maxillofacial abnormalities and is the rationale for choosing a method for treating patients with a gnatic form of mesial occlusion or for compensatory orthodontic treatment. The proposed technique is a convenient express method for the diagnosis and treatment planning of dentoalveolar anomalies.

Objective: To compare the effects of extraction, non-extraction and air-rotor stripping treatments on mandibular dental arch dimensions, lower incisor positions and evaluate their effects on the stability of the treatment. Study design: The sample consisted of 44 patients with Class I malocclusion and moderate crowding including 15 patients treated with extraction, 13 with air-rotor stripping (ARS), and 16 with non-extraction treatment. The records were taken at pretreatment (T0), end of active orthodontic treatment (T1), minimum 3 years post-treatment (T2). The model and cephalometric measurements were evaluated. For statistical analyses ANOVA and Welch test was applied. Results: At post-retention period Little's irregularity indices were increased to 1.96 mm, 2.38 mm and 3.59 mm for extraction, ARS and non-extraction groups respectively (p<0.05). At T1-T2, intercanine widths were decreased significantly at all groups (p<0.05). The arch length and arch depth decreased significantly at extraction group (p<0.05) from T0 to T1 and remained the same at T2 (p>0.05). The lower incisors were retroclined with treatment and slightly proclined at post-retention period in extraction group. In ARS and non-extraction group, lower incisors proclined with treatment and remained the same at post-retention. Conclusion: At all groups the irregularity indices relapsed but did not return to pretreatment values. Although significant increase at intercanine width was only observed in non-extraction treatment, at post-retention phase, intercanine widths were significantly decreased at all groups. The changes at lower incisor inclinations relapsed slightly in extraction group but remained the same in the other groups.

This chapter discusses the growth of the face, development of the dentition, and prevention and correction of occlusal anomalies, providing a concise overview of the fundamentals of orthodontics. Definitions relevant to orthodontics are outlined as well as a structured approach to orthodontic assessment. The Index of Orthodontic Treatment Need is explained, and its implications highlighted. The chapter also simplifies cephalometrics before detailing the management of increased overbite, anterior open bite, increased overjet, and various other dental and skeletal malocclusions. A further area included in this chapter is orthognathic surgery. The section includes diagnosis and treatment planning in these cases, surgery, and distraction osteogenesis.

Detailed Assessment

The Tweed-Merrifield technique is based on a simple and detailed diagnosis and therapy considering a shape of the dental arch with preservation or improvement of facial features.<b> Aim</b>. The aim of the work was to present a reliable and structured method to analyse diagnostic models used in the Tweed-Merrifield technique. <b>Material and methods</b>. Based on a review of available literature the paper presents rules to assess an amount of space in the arch for tooth movements used in the Tweed-Merrifield technique. The analysis of models in this technique is based on the assessment of three segments of the dentition: anterior, middle and posterior. With regard to each segment actual width of teeth and amount of space available in the arch is measured. Additionally, in the anterior segment evaluation of alignment of lower incisors in relation to FMIA (Frankfort Mandibular Incisor Axis Angle) or IMPA (Lower Incisor Mandibular Plane Angle) cephalometric angles as well as assessment of the soft tissues thickness is important. With regard to the middle segment of the dentition measurement of the curve of the Spee plays an important role, and with regard to the posterior segment it is also necessary to evaluate expected growth in patients at the developmental age. <b>Conclusion</b>. A detailed assessment of possible tooth movements and treatment management taking into account an initial shape of the arch allow to obtain stable therapeutic outcomes. <b>(Warmuz J, Kawala B, Minch L.

ABSTRACT Objective:  To correlate the objective cephalometric measurements with subjective facial esthetics in patients with bimaxillary protrusion. Materials and Methods:  The sample consisted of 60 Asian-Chinese patients with bimaxillary protrusion who met the inclusion criteria. The facial esthetics of posttreatment profile and the change of profile on standardized lateral photographs were rated by a panel of 10 orthodontists and a panel of 10 lay persons with bimaxillary protrusion. All of the pretreatment and posttreatment cephalograms were digitized and traced. Twenty-five cephalometric measurements were constructed and analyzed. Correlations between the subjective facial esthetic scores and each cephalometric measurement were evaluated. Results:  The cephalometric measurements correlated with the facial esthetic scores of posttreatment profile given by the orthodontist and the lay persons were basically the same. For the evaluation of posttreatment profile in bimaxillary protrusion patients, the upper and lower lip to E-line, upper and lower incisor tip to AP plane, Pg-NB distance, mentolabial angle, and sulcus depth correlated significantly with the esthetic score. For the evaluation of profile change during orthodontic treatment, retraction of upper incisor relative to AP plane or the perpendicular line through sella (line Y), change of upper incisor inclination, change of mentolabial sulcus depth, and retraction of lips relative to E-line were correlated positively with the esthetic value. Conclusions:  Cephalometric measurements of lip position, incisor position, and chin morphology were key parameters correlated to facial esthetics.

This article reports the orthodontic diagnosis and treatment planning carried out with a 14-year and 5-month-old female patient with esthetic and functional complaints. She presented an Angle Class I malocclusion, anterior crossbite and severe crowding in both maxillary and mandibular arches, in addition to a lightly concave straight facial profile. Orthodontic treatment did not require extraction. Crossbite was corrected by protrusion of upper teeth, which contributed to alignment and leveling of teeth, in addition to improving the patient's facial profile. The case was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO) as a requirement for the BBO certification.
