Full mouth rehabilitation using orthodontic treatment and implants in patient with collapsed occlusion: A case report / 대한치과보철학회지

The distance between the natural teeth and the implants is an important factor in preserving the periodontal tissues and esthetics. And abnormal positional displacement and tilting of the teeth during restorative procedure may require intentional root canal treatment and may affect masticatory function. This report is to present a successful full mouth rehabilitation of a patient with uneven dentition and collapsed occlusion using orthodontic and implant treatment. The patient had no symptoms or discomfort of temporomandibular joint disorder such as pain or sound. The orthodontic treatment was continued until implant provisional prosthesis delivery. And the vertical height of occlusion was elevated 2mm on anterior basis for anterior teeth protection and esthetics. After the orthodontic treatment, the implant abutments and natural teeth were finally restored with porcelain-fused-to-metal crowns and bridges. Satisfactory function and esthetic outcomes are observed after 6months of follow up.

Effect of different teeth arrangement methods on the masticatory efficiency of complete dentures / 实用口腔医学杂志

Objectives:To evaluate the effect of different teeth arrangement methods on the masticatory efficiency of complete dentures.Methods: Three complete dentures for each of ten edentulous patients were made respectively by using maxillary teeth arrangement,mandibular teeth arrangement and comprehensive teeth arrangement methods.After three months of wearing,the masticatory efficiency of the three complete dentures was tested by light absorption method,and was compared to that of dentulous subjects.Results:The masticatory stroke and masticatory efficiency in denture wearing group were fewer and weaker than those in dentulous group in either bilateral mastication or unilateral mastication. Good masticatory efficiency was gained after three months of wearing the complete dentures made by the three different teeth arrangement methods.There were no significant difference in the masticatory stroke and masticatory efficiency of complete dentures made by mandibular teeth arrangement and comprehensive teeth arrangement methods,but they were both higher than those made by maxillary teeth arrangement method.Conclusions:The complete dentures made by mandibular teeth arrangement method and comprehensive teeth arrangement method are feasible for restoration of masticatory efficiency of endentulous patients.
