The authors concluded that the risk of adverse effects as bone dehiscence may be present during retraction of maxillary and mandibular anterior teeth [20]. Orthodontic braces usually need adjusting every 4 to 6 weeks. Sarikaya et al. After six months of surgery stabilization, the fixed appliance was removed and Hawley plate and mandibular retainers were placed (Figure 6). Copyright © 2014 Fabio Pinto Guedes et al. What does decompensation mean? Thus the desired facial and occlusal changes are provided with adequate pre-surgical incisor decompensation, which also mini-mises the need for protracted post-surgical orthodontic … Analysis of occlusion evidenced Class III interarch relationship and anterior and posterior crossbite with a negative overjet of 6 mm. Presurgical orthodontic decompensation alters alveolar bone condition around mandibular incisors in adults with skeletal Class III malocclusion Boyang Sun1,2*, Jun Tang3*, Ping Xiao1, Ying Ding2 1Department of Stomatology, Tangshan Branch of Jinling Hospital, School of Medicine, Nanjing University, A critical analysis of the cost benefit of the decompensation protocol for patients with dentoskeletal discrepancies was performed. The bone dehiscences observed in this case seem to be related to the quantity of crowding and incisor movements in the buccolingual direction.

The facial and occlusal results remained stable 30 months after removal of appliances (Figure 7), including the clinical periodontal conditions. Postdecompensation facial and intraoral photographs. This concern is even greater when there is both sagittal and vertical skeletal involvement, as in skeletal Class III patients with excessive vertical facial dimension where the mandibular symphysis and alveolar ridge are even thinner [1, 7, 10, 12]. Although the “surgery-first” approach has been introduced back in 2009 [], this approach is not an entirely new technique, Epker and Fish stated that surgical procedures … The decompensation movement before orthognathic surgery had an influence on the buccal and lingual bone insertion levels of the incisors. The surgical orthodontic treatment is indicated when the patient present a significant facial or dentoalveolar deformities, in which the orthodontic and/or orthopedic treatment alone would not achieve satisfactory results [15–17]. Occluding the dental casts in Class I showed that maxillary constriction was mild and a small amount of dentoalveolar expansion was not necessary to achieve an adequate transversal interarch relationship. Pre- and postdecompensation buccal alveolar bone level values. A male patient aged 20.5 years sought orthodontic treatment with the chief complaint of facial disharmony. Every surgical orthodontic case requires decompensation to remove the compensatory mechanisms that have come int0o play. The process of cementing orthodontic bands to your teeth. In this abnormal relationship, the upper front teeth and jaw project further forward than the lower teeth and jaw. It should be highlighted that the greatest bone dehiscences were observed on the lingual aspect of mandibular incisors. Among the typ … Definition: Orthodontic treatment with a limited objective, not involving the entire dentition. Meaning of decompensation. Decompensation definition: the inability of an organ, esp the heart , to maintain its function due to overload... | Meaning, pronunciation, translations and … Pre-surgical orthodontic treatments have the objective of establishing harmony between the dental arches by moving the teeth to ideal positions in relation to their bony bases, in order to achieve adequate antero-posterior occlusal and transverse relationships at the moment of surgery. Bonding: The process of attaching brackets to your teeth using a special safe adhesive. decompensation also facilitates the possibility of fully corrected inter-arch relationships at the time of surgery by optimising the surgical movements. At this stage, the facial profile and occlusal relationships were worse than in the initial stage (Figure 3). Orthognathic surgery is exacting and requires systematic presurgical decompensation with frequent reference back to the original study models.
