Abstract: Objective:To evaluate the clinical effects of the key-way attachment in fixed restoration of mandibular first and second molar deletion.Methods:A 1 -5-year follow-up study was conducted on 1 6 patients with the reconstruction of mandibular first and second molar deletion.The key-way attachment was used as a connector in the fixed partial denture,with the third molar and 2 sec-ond premolars as the abutments.Results:During 5-year follow-up,1 3 of the fixed partial denture were good-looking,stable and functioning.The abutments were stable,without endodontic and periodontal disease.No absorption of alveolar bone was observed by X-ray examination.3 cases were failure.Bleeding on probing of third molar was observed in 1 patient 1 year after restoration.1 re-tainer of a denture on the third molar was loosing 1 .5 years after restoration.1 patient had dental caries on the third molar 5 years af-ter restoration.Conclusion:The key-way attachment as a connector is useful in fixed partial denture in patients with mandibular first and second molar deletion.
