Abstract Fourteen patients with upper completely edentulous arch and only one standing natural canine. Each patient received dental implants with 10.5mm length and 3.8 diameter at the canine regions of the mandible. After the osseointegration period (4 months) the patients were divided into two groups. Seven patients for each. group I patients received mandibular over-denture retained by bar clip attachment and supported by implant on one side and natural tooth on the other side. group II patients received lower implant splinted to the natural canine by bar joint attachment utilizing soft liner material. Both groups were supplied with conventional maxillary complete dentures. The patients were evaluated clinically and radiographically immediately after over-denture delivery, after six months and after twelve month. The clinical evaluation included; implant mobility and gingival index. The radiographic evaluation included; measuring mesial, distal, buccal and lingual bone height difference.Cone Beam Computed Tomography was used to obtain panoramic and cross sectional views for both implant and natural for accurate measurements analysis. Statistical analysis was performed in order to compare between the two groups. The results of the study showed no implant mobility with slight non-significant gingival inflammation in both groups. Statistically, group (I) shows significant bone loss than group (II) around both dental implant and natural tooth. |
