Long-Term Follow-up of a Patient with Multiple Congenitally Missing Teeth Treated with Autotransplantation and Orthodontics

This study describes the management of a case of multiple missing teeth involving premolar autotransplantation, orthodontic treatment, and a 6-year follow-up of autotransplantation. The prognosis of the transplant was good with a satisfactory crown-root ratio. Autotransplantation is a viable treatment option that eliminates the need for prosthetic therapy or implants for children with missing permanent teeth.

Comparison of Modified Teuscher and Van Beek Functional Appliance Therapies in High-Angle Cases

The aim of this study was to investigate the effects of modified Teuscher and van Beek functional appliances on the skeletal and dento-alveolar pattern in high-angle Class II, Division 1 patients.The collective consisted of 32 patients with a high-angle Class II, Division1 malocclusion. The modified Teuscher activator was applied to a group of twelve patients, and the van Beek activator to a group of ten patients. A control group of ten subjects was used for comparison purposes. The mean chronological ages of the groups were 12, 11.8 and 11.5 years, respectively. 64 cephalograms taken before and after the treatment were evaluated. Intra-group measurement relations were determined by the Wilcoxon test, and inter-group relations by analysis of variance and Duncan tests, using SPSS statistical software.The following results were observed for both treated groups without any change in growth direction: inhibition of maxillary growth, stimulation of mandibular growth, retrusion of upper incisors, distal tipping of upper molars, and reduction of overjet and overbite compared with the control group. The decrease in overbite in the van Beek group was due mainly to intrusion of the incisors, and in the modified Teuscher Group to molar extrusion.Both activators were considered preferable in terms of vertical control of the facial height in high-angle cases with deep overbite. However, stimulation of mandibular growth in the modified Teuscher activator group was found to be more significant than in the van Beek activator group.ZusammenfassungZiel dieser Studie war, die skelettalen und dentoalveolären Auswirkungen einer Behandlung mit einer modifizierten Teuscher-Apparatur und der Therapie mit dem Funktionsgerät von van Beek bei 32 Klasse-II/1-Patienten mit ausgeprägtem vertikalen Wachstumsmuster zu untersuchen.Zwölf Patienten, im Durchschnitt 12 Jahre alt, erhielten den modifizierten Teuscher-Aktivator, eine weitere Gruppe von zehn Patienten mit einem Durchschnittsalter von 11,8 Jahren wurde mit dem Van-Beek-Aktivator therapiert. Die Kontrollgruppe bestand aus zehn Probanden, die im Durchschnitt 11,5 Jahre alt waren. 64 Fernröntgenbilder, die vor und nach der Behandlung angefertigt worden waren, wurden bewertet. Messwerte innerhalb einer Gruppe wurden mit Hilfe des Wilcoxon-Tests ausgewertet; zum Gruppenvergleich wurden die Varianzanalyse und der Duncan-Test unter Benutzung der SPSS-Statistik-Software angewandt.Folgende Ergebnisse wurden bei beiden behandelten Gruppen im Vergleich mit der Kontrollgruppe beobachtet, ohne dass eine Änderung in der Wachstumsrichtung auftrat: Hemmung des Wachstums der Maxilla, Anregung des Wachstums der Mandibula, Retrusion der Oberkieferinzisivi, Distalkippung der Oberkiefermolaren, Reduktion von Frontzahnstufe und Überbiss. In der Van-Beek-Gruppe entstand die Reduktion des Überbisses im Wesentlichen durch Intrusion der Inzisivi, in der mit der modifizierten Teuscher-Apparatur behandelten Gruppe durch die Extrusion der Molaren.Beide Aktivatoren erwiesen sich zur vertikalen Kontrolle der Gesichtshöhe bei Patienten mit ausgeprägt vertikalem Schädelaufbau und einem tiefen Überbiss als geeignet. Trotzdem war die Stimulation des Unterkieferwachstums in der mit dem modifizierten Teuscher-Aktivator behandelten Gruppe signifikanter als in der Gruppe mit dem Van-Beek-Aktivator.

Effects of bite-jumping appliances on mandibular advancement in growing rats: A radiographic study

Objective: The aim was to evaluate the effects of the use of mandibular advancement appliances on mandibular growth in growing rats. Materials and Methods: Twenty-four 8-week-old male Wistar albino rats were randomly divided into two experimental groups (12 rats each): Group I was a control group, and Group II was the mandibular advancement appliance group. A functional bite-jumping appliance was used in Group II to promote mandibular advancement. Anatomical changes in the condyle and mandible were evaluated by comparing radiographic results from before and after the study, with angular and linear measurements. Friedman and Mann-Whitney U-tests were used in statistical analysis. Results: According to the radiographic results, the growth of mandibles and condyles in Group II was significantly greater than with the length of the condylar process (A-B) and distance from condyle to menton (A-D) variables (P < 0.05). In addition, Group I showed greater mandibular base growth than did Group II (P < 0.05). Conclusions: We conclude that the use of an intraoral bite-jumping appliance can stimulate condylar growth and increase sagittal mandibular advancement in growing rats.

Orthopedic Treatment of Skeletal Class III Malocclusions With Maxillary Deficiency

ABSTRACT Objective: The purpose of this study was to compare the treatment effects of a double-plate appliance (DPA) and a double-plate appliance and facemask combination (DPA-FM) in correcting Class III malocclusions. Materials and Methods: The material consisted of lateral cephalometric radiographs of 40 children with skeletal and dental Class III malocclusion. In the first treatment group, 13 patients (mean age: 10 years 3 months) were treated with DPA. In the second treatment group, 15 patients (mean age: 10 years 9 months) were treated with DPA-FM. In the third group, 12 patients (mean age: 10 years 6 months) were observed without treatment for 9 months. Statistical evaluation was made by ANOVA, Duncan, and paired t tests. Results: The increases in SNA and ANB angles were significantly greater in the DPA-FM group than in the DPA group. The proclination of upper incisors (U1/NA) and retroclination of lower incisors (L1/NB) were significantly greater in the DPA group than in the DPA-FM group. The retro...
