While polyethylene terephthalate glycol (PETG) is widely used in orthodontic appliances such as clear aligners and retainers, there is limited experimental data assessing its performance under functional stresses, such as those encountered during dental movements and palatal expansion. This study aims to evaluate the ability of PETG thermoplastic material to withstand deformation under functional and expansion forces, specifically within the context of orthodontic applications. To estimate the firmness of the screw within the appliance, a universal Instron testing machine was used to record the forces released by each activation of the expander within the upper part of 10 clear modified twin blocks (MTBs) made from PETG and compare it with that released by 10 conventional twin blocks (CTBs).

Materials And Methods: The sample comprised 28 skeletal Class I adolescents with dental Class II malocclusion and maxillary crowding of >4 mm who received nonextraction treatment. Fourteen patients were treated with a modified MARPE with distalizer (MMD), while another 14 patients were treated with a modified RPE with distalizer (MRD).

Traditional surgical techniques for segmental maxillary surgery include a combination of interdental osteotomies with paramidline bony cuts while keeping the palatal soft tissue intact. Besides surgical complexity, segmental maxillary procedures have been associated with higher incidence of relapse and complications. We present our experience with specific hard- and soft-tissue modifications (midline bony osteotomy and reflection of palatal soft tissue with carefully designed incisions) which will allow surgeons to perform larger expansions with a low incidence of complications and decreased relapse.
