Abstract
Objective: To evaluate patients’ satisfaction, biting force measurement, and radiographic evaluation of abutment teeth of tooth implant-supported fixed partial denture, unilateral attachment, and conventional partial denture in mandibular distal extension cases. Materials and Methods: Twenty-four participants were selected according to the following criteria: participants with unilateral mandibular distal extension with last standing second premolar abutment; participants having abutments with sufficient occluso-gingival height and good periodontal condition. Participants were divided into the following three equal groups: participants of the implant group received fixed tooth implant-supported fixed partial dentures, attachment group participants received unilateral attachment removable partial dentures, and conventional group participants received conventional removable partial dentures. The evaluation included patient satisfaction using “OHIP14” questionnaires, biting force measurement, and radiographic evaluation of terminal abutments using the ANOVA test. Results: Participants of the implant group were mainly satisfied with their prosthesis than the attachment group, which is higher than the conventional. Regarding biting force measurement, there is a statistically significant difference (p < 0.05) between all groups, including the implant group and attachment group, as well as between attachment and conventional group (p < 0.05). The conventional group showed statistically significant (p < 0.05) highest mean bone loss, while there was no statistically significant difference between implant and attachment groups; both showed statistically significantly lower mean amounts of bone loss. Conclusion: The tooth implant-supported fixed prosthesis could be considered a superior line of treatment for managing distal extension cases. Unilateral attachment, which is considered an excellent alternative in the case of implant placement, is not recommended.

Summary
The proportion of partially dentate patients is increasing due to the maintenance and improvement of oral health care. The main drawbacks of treatment with removable partial dentures are caries, alveolar ridges resorption, loss of correct occlusion, fracture of clasps or occlusal rests, and inflammation of the underlying mucosa from traumatic irritation [8 - 10]. Another line of treatment is implanted tooth-supported prosthesis. Implants can be connected to stable and rigid teeth [11 - 13] It seems that splinting with an extra tooth may provide more effective compensation for compromised periodontal supports [14]. The research hypothesis was that the implant group would provide a better result than other groups
