Effects of orthodontics on the facial profile: A comparison of changes during nonextraction and four premolar extraction treatment

INTRODUCTION: Patients with dental Class II bialveolar protrusion are generally treated by extracting the four first premolars or two first and two second premolars, and retracting the anterior teeth. This case report describes the treatment of an adult patient with bialveolar protrusion, a Class II canine and molar relationship, and lip protrusion. METHODS: In this patient, the maxillary right second molar (1.7) had to be extracted due to extensive caries. To create sufficient space to retract the anterior teeth, the maxillary right posterior teeth were distalized with a maxillary posterior mini-implant (1.2~1.3 mm in diameter, 10 mm long), which was placed into the maxillary tuberosity area and allowed an en masse retraction of the maxillary anterior teeth. RESULTS: Overall, mini-implant can provide anchorage to produce a good facial profile even without additional premolar extraction in cases of dental Class II bialveolar protrusion with the hopeless second molar. CONCLUSION: The total treatment period was 42 months and the results were acceptable for 34 months after debonding.

Extraction Treatment

In our orthodontic practice we have seen a recent spurt of increasing numbers of young adults who desire cost effective, non surgical correction of malocclusion and accept dental camouflage as a treatment option to mask the skeletal discrepancy. Usually over 10 mm overjet with traumatic bite is very difficult to treat without extraction; therefore this case is handling so carefully that the upper central incisors cannot loose or dead because of excessive force. In this case patient growth is complete and therefore the only option is fixed orthodontic treatment. So here the challenge is reduction of overjet and correction of traumatic bite without any extraction and is careful to save the tooth vitality. Following treatment marked improvement in patient’s smile, facial profile and lip competence were achieved and there was a remarkable increase in the patient’s confidence and quality of life.Ban J Orthod & Dentofac Orthop, April 2015; Vol-5 (1-2), P.30-32

Ektopik kaninus seringkali dijumpai dalam praktek bidang ortodontik. Sebagian orang yang merasa terganggu dengan keadaan ini akan datang ke dokter gigi untuk mendapatkan perawatan. Perawatan ortodontik dilakukan untuk mengoreksi gigi yang ektopik dan memperbaiki fungsi estetik. Pada perawatan kasus ektopik kaninus ini, pencabutan gigi premolar kedua dilakukan karena tidak diperlukan perubahan profil. Teknik Begg merupakan teknik ortodontik yang menggunakan gaya ringan dengan kawat busur berpenampang bulat. Kawat busur akan bergerak bebas tanpa friksi dan menghasilkan gerak tipping mahkota gigi. Tujuan dari studi kasus ini adalah untuk memaparkan perawatan kaninus ektopik dalam tahapan teknik Begg. Pasien perempuan usia 19 tahun mengeluhkan gigi depan yang gingsul dan berjejal. Hasil pemeriksaan objektif menunjukkan ektopik pada gigi 13, 23 dan 33, overbite 5 mm, crowding anterior mandibula, dan crossbite anterior pada gigi 22 dan 33. Maloklusi kelas I skeletal dengan protrusif bimaksiler dan protrusif bidental, ektopik kaninus maksila bilateral, ektopik kaninus mandibula unilateral, deep bite, crowding anterior mandibula dan crossbite anterior. Dilakukan perawatan ortodontik cekat teknik Begg multiloop dengan pencabutan 15, 25, 36 dan 46. Sembilan bulan setelah perawatan, crossbite anterior, dan gigi 13, 23 dan 33 yang ektopik telah terkoreksi. Crowding anterior mandibula telah mengalami perbaikan dan perawatan masih berlanjut hingga saat ini. Perawatan teknik Begg multiloop dengan pencabutan gigi premolar kedua merupakan alternatif perawatan untuk koreksi ektopik kaninus, jika tidak diperlukan perubahan profil wajah pasien. ABSTRACT: Ectopic Canines Treatment Using Begg Technique with Second Premolar Extraction. Ectopic canines are often found in the field of orthodontic practice. People who are annoyed with this situation usually come to an orthodontist to seek for treatment. Orthodontic treatment has been performed to correct ectopic teeth and improve the function of aesthetics. In this case of ectopic canines, a second premolars tooth was extracted because profile changes are not required. Begg orthodontic technique is a technique that uses light forces by using round archwire. Archwire will move freely without friction and produce a tipping movement of dental crowns. A 19 year old female patient complained of ectopic and crowding anterior teeth. The objective examinations find ectopic of 13, 23 and 33, overbite: 5 mm, anterior mandibular crowding, and anterior crossbite of 22 and 33. Class I skeletal malocclusion, bimaxillar protrusive, bidental protrusive, bilateral ectopic canine maxilla and lateral ectopic canine mandibula, deep bite, anterior crowding and anterior crossbite. A fixed orthodontic treatment was performed by multiloop Begg technique with tooth extraction of 15, 25, 36, and 46. 9 months after treatment, anterior crossbite and ectopic 13, 23, 33 have been corrected by using multiloop Begg technique. Crowding in the lower arch has improved compared to initial condition and treatment still continues to this day. Multiloop Begg technique with second premolars extraction is an alternative treatment for ectopic canines correction if patient’s facial profile changes are not required.

ABSTRACT Objective: The effect of total arch distalization using orthodontic mini-implants (OMIs) combined with interproximal stripping (IPS) and second premolar extraction was investigated in Class I malocclusion patients. Materials and Methods: A total of 66 consecutively treated Class I malocclusion (Class I molar relationship; 0 mm < overbite and overjet < 4.5 mm) patients ranging in age from 17 to 44 years who received single-phase treatment were included in this study. Pre- and posttreatment lateral cephalograms and dental casts were measured and compared statistically. Results: In the distalization with IPS group, 3.6 mm and 3.8 mm of crowding in the upper and lower arches, respectively, were resolved, and 3.8 mm and 3.2 mm of upper and lower incisor retraction, respectively, were achieved simultaneously by the treatment. As a result of the second premolar extraction treatment, 3.9 mm and 3.6 mm of crowding in the upper and lower arches, respectively, were resolved, and 3.3 mm and 3.2 mm of incisor retraction, respectively, were achieved during treatment. There was no statistically significant difference in the amount of crowding and incisor retraction between the two groups. Conclusions: Total arch distalization using an OMI with IPS did not yield a significantly different treatment result compared to second premolar extraction treatment.

Tooth Extractions

Abstract The esthetic benefits are among the main goals of orthodontic treatment; therefore, tooth extractions have been avoided as a protocol for orthodontic treatment because they may impair the facial profile. The present article discusses aspects as the magnitude and response of soft tissue profile due to changes in incisor positioning, and the effect of different sequences of premolar extraction. One case report illustrates the subject, with favorable and stable esthetic and occlusal outcomes five years after orthodontic treatment with extraction of second premolars.

Abstract Objectives: To determine the amount of variation in overjet and overbite that may result from changes in upper and lower incisor angulations following upper first premolar extraction treatment in Class II malocclusions. Materials and Methods: Typodonts were set up to simulate a skeletal Class II occlusion treated with upper first premolar extractions. The upper incisor angulation was altered through a range from 100° to 120° to the palatal plane by 2° increments. The overjet and overbite were measured with every 2° of upper incisor angulation change. A regression analysis was performed on the experimental data, and the regression coefficients, slope, and intercept were estimated. Results: Excessive proclination of the lower incisors will result in an abnormal overjet and overbite relationship for any magnitude of upper incisor angulation. A normal lower incisor angulation facilitates the attainment of an optimal occlusion. Excessive palatal root torque of the upper incisors will result in an increase in overjet and a consequent decrease in overbite. If the upper incisors are excessively retroclined, an edge-to-edge incisor relationship will result. Conclusion: Class II camouflage treatment with upper first premolar extractions requires correctly angulated incisors to achieve optimal buccal segment interdigitation and incisor relationship. Labial root torque and interproximal reduction of the lower anterior teeth should be considered when the lower incisors are excessively proclined.

ABSTRACT Objective: The purpose of this study was to compare the dental and skeletal effects of canine retraction using conventional anchorage reinforcement systems and comparing them with the usage of TADs. Materials and Methods: The sample consisted of 50 patients having Class I malocclusions with bimaxillary protrusion indicated for first premolar extraction, and allocated into two groups. The first group consisted of 25 patients with a mean age of 18,7 years (min:14, max:22 years, 16 girls and 9 boys) that TADs were applied as an anchorage mechanic between attached gingiva of upper second premolar and first molar teeth. The second group consisted of 25 patients with a mean age of 19,4 years (min:15, max:23 years, 14 girls and 11 boys) that conventional molar anchorage with Transpalatal arch (TPA) was applied for the anchorage mechanics against canine retraction. Results: The results showed that mean mesial movement and the tipping of the first molars in TAD group between T0 - T1 were insignificant (P > 0,05), however in the TPA group were significant (P<0,01). Vertical movement of the molars were not significant when two groups were compared (P>0,05). Conclusion: Although TPA is a useful appliance, it doesn't provide an effective anchorage control on anteroposterior movement maxillary first molar teeth concerning first premolar extraction treatment. TADs are more convenient to provide absolute anchorage during maxillary canine retraction in contrast to transpalatal arch.
