“…If so, this factor should be considered when comparing the stability of deep-bite correction in adults and adolescents. Additionally, the study by Pollard et al [24] suggests that patients with more divergent facial patterns exhibit less deepbite relapse [24]. …”

Objectives Deep bite occurs in about 15% to 20% of the US population. Currently, it is unknown which types of correction are most efficient or stable. The purpose of this systematic review was to investigate factors related to stability of deep-bite correction. Materials and Methods An electronic search of 4 databases was performed from January 1, 1966 to June 27, 2012. Studies were considered for inclusion if they reported on deep bite samples that underwent orthodontic treatment in the permanent dentition. Records were required at the initial, posttreatment, and 1-year posttreatment times. Hand searching of reference lists of the included studies was performed. Data were abstracted using custom forms, and risk of bias was assessed using a modified Newcastle-Ottawa Scale. Results Twenty-six studies met the inclusion criteria. Most were case series, with considerable potential for bias. The significant heterogeneity of the studies precluded meta-analyses, and only descriptive statistics and stratified comparisons were reported. On average, patients underwent significant overbite improvement during treatment, and most of the correction was maintained long-term. Across all studies, the mean initial overbite, posttreatment overbite, and long-term overbite were 5.3, 2.6, and 3.4 mm, respectively. Initial severity appeared to be related to long-term stability. However, this relationship was difficult to isolate from other factors. The length of follow-up did not appear to be related to the amount of relapse. Conclusions Although the quality of the current evidence is not high, patients with deep-bite malocclusion appear to undergo relatively successful treatment, and most of the correction appears to be stable.

“…The vertical position of the most proclined maxillary (U1) and mandibular central incisors (L1), mandibular first premolar (L4) and first (L6) and second (L7) molars was measured perpendicular to palatal and mandibular planes, respectively (11). The arch levelling was measured by the changes in the measurements of the distances of L1, L4, L6, and L7 to the mandibular plane.…”

“…Relapse may develop in some patients because the downward and forward mandibular growth continues longer than that of the upper jaw, forcing the lower anterior teeth back and up, or in other subjects because strong masticatory muscles tend to intrude posterior teeth. Accordingly, if certain patients can be identified as high-risk candidates for overbite relapse, retention strategies might need to be altered for them to achieve the most stable outcomes (11). Therefore, the aim of this study was to analyse the long-term stability of COS depth in relation with different skeletal vertical patterns 2 years after the end of treatment with fixed appliances and continuous archwires.…”

Objectives:The aim of the study was to evaluate the curve of Spee (COS) stability in patients treated with continuous archwires with different vertical patterns. Methods: The study sample consisted of 60 patients (28 males, 32 females; mean age 19.8 ± 1.4 years) presenting with COS depth of at least2 mm at baseline. For each subject, lateral cephalograms and dental casts were available before treatment (T1), at the end of orthodontic therapy (T2), and 2 years after the end of treatment (T3). All subjects were divided into three groups according to vertical facial patterns. Cephalometric parameters were used to evaluate the dental movements after treatment. COS depth was measured on digital casts. Mean differences between vertical facial subgroups were contrasted by means of analysis of variance test (P < 0.01). Results: In low-angle subjects, COS levelling occurred through advancement and intrusion of lower incisors, whereas in high-angle patients, the COS was flattened through extrusion and uprighting of lower posterior teeth. In the low-angle group, a significant relapse of lower incisors inclination was observed. Differently, the high-angle group exhibited a greater stability of COS obtained by stable extrusion of posterior teeth. Conclusions: The long-term instability of flared incisors determined the relapse of overbite and COS depth in the low-angle group.

“…Esta tendência em longo prazo também foi observada durante um acompanhamento de 5 a 10 anos após o tratamento isolado com Herbst para casos de recidiva em relação a casos estáveis (PANCHERZ, 1991). O padrão de crescimento com uma rotação da mandíbula no sentido anti-horário combinado com uma suave lingualização dos incisivos inferiores, com o tempo pode ser um fator influente na recidiva do trespasse vertical (POLLARD et al, 2012). Bock et al (2017) observaram que o uso da contenção canino a canino por um período prolongado foi benéfico para a estabilidade do trespasse horizontal, vertical e alinhamento dentário em longo prazo de 15 anos em relação a ausência do uso da mesma.…”
