A patient with defective dentition in the upper jaw was placed with implant in left upper jaw. Telescopic overdenture was fabricated and supported by the implant and canine tooth in right upper jaw. The patient felt very comfortable, and this type of restoration could provide sufficient stability and maintain tooth and peri-implant tissues healthy. The preliminary clincal results of this restoration show that isolated canine tooth and single implant supported telescopic overdenture are feasible.

Spinal muscular atrophy(SMA) is a serious neuromuscular degenerative disease that severely impairs the quality of life for patients and entire families.The emergence of disease-modifying treatments such as nusinersen and risdiplam has gradually changed the natural course of SMA patients.It is particularly important to include the activities of daily living(ADL) ability reported by patients or caregivers in the comprehensive assessment of SMA patients.There are many ADL-related assessment tools, and studies have found that disease-modifying treatments can somewhat improve the ADL ability of SMA children.This article reviews the progress on the effect of disease-modifying treatments on ADL in SMA patients, which can provide a reference for exploring more comprehensive and effective assessment tools and treatment decision-making in subsequent clinical practice.
