Digital repair for a patient with limited mouth opening:a case report and literature review
摘要
Abstract
Objective To explore an accurate method to obtain an intraoral model of patients with specific limited mouth opening(microstomia)due to systemic scleroderma.Methods This study followed medical ethics,and informed consent has been obtained from patients.A case of Ken's Type Ⅰ mandibular dentition defect scleroderma with limited mouth opening was addressed with digital technology as the leading method combined with the traditional impression method of segmental impression.Individual trays were made based on the patient's left and right mandibular dentition,and segmented molds were obtained.Simultaneously,intraoral scanning was performed to obtain the morphological data of both the soft and hard tissues of the upper and lower mandibles.After each part of the model was obtained,the man-dibular model was scanned and digitally aligned to form the final denture model,and the final removable partial denture was designed and made by computer aided design/computer aided manufacturing(CAD/CAM)technology.At the same time,combined with the literature,the diagnosis and treatment of removable partial denture in patients with limited mouth opening were retrospectively analyzed.Results The denture was well retained and achieved a good repair ef-fect.The patients expressed satisfaction with the mastication efficiency and other functions of the denture.The findings of the literature review show that the integration of digital technology with the traditional impression method,along with computer fitting,can accurately obtain the patient's oral model and facilitate successful follow-up repairs.However,when the anterior mandibular dentition of the patient is absent,the margin of error is increased in this procedure,which deserves further exploration.Conclusion Utilizing digital technology as the leading method,combined with the tradi-tional impression method of segmental impression,for the repair of dental defects in patients with limited mouth open-ing,has proven to be effective.Thus,patients report a positive medical experience with high satisfaction,indicating that this approach is worthy of clinical promotion.关键词
