Novel maxillary arch expander for bilateral cleft lip and palate patient and correction method

Abstract

The invention discloses a novel maxillary arch expander for a bilateral cleft lip and palate patient and a correction method. The maxillary arch expander comprises a hyperbolic labial arch 1, an adjacent hook 3, an arrow clamping ring 4, a first spiral arch expander 5, a second spiral arch expander 6, a third spiral arch expander 7 and a Y-shaped splitting base support. The Y-shaped split base support comprises a front base support 81, a left base support 82 and a right base support 83 which are connected through a spiral arch expander. The Y-shaped split base support covers the palate part and the palate side of the dentition; two adjacent hooks 3 are respectively positioned between the left and right second premolar teeth and the first molar teeth and are fixedly connected with the Y-shaped split base support; the two arrow clamping rings 4 are located on the left first molar tooth and the right first molar tooth respectively and fixedly connected with the Y-shaped split base support. The hyperbolic labial arch 1 is positioned in a mesial anterior tooth region of the fracture and is fixedly connected with the Y-shaped split base support. According to the invention, the problem that the maxillary expansion of a patient with cleft lip and palate on both sides cannot control the anteroposterior process of the front jaw and the over-wide fracture at the same time is solved, the correction procedure is simplified, and the treatment time is shortened.

Description

technical field

[0001] The invention belongs to the technical field of stomatology, in particular to a novel maxillary arch expander and correction method for patients with bilateral cleft lip and palate. Background technique

[0002] Cleft lip and palate is the most common congenital birth defect of the oral cavity and face. The prevalence rate in my country is 0.082-0.16%, ranking first among all birth defects. Sequential treatment for cleft lip and palate patients has become the consensus of experts and scholars at home and abroad, that is, patients at different growth and development stages receive different treatments according to their own conditions, including cleft lip surgery, cleft palate surgery, orthodontic treatment, bone graft surgery, voice training, etc. . Due to the impact of congenital development and surgery, the incidence of malocclusion in such patients is very high, about 97%. Orthodontic treatment plays an important role in the sequence treatment of ...
