Abstract
Objective: This study was carried out to radiographically evaluate the effect of the two different CAM techniques of BioHpp frameworks fabrication (milled and pressed) on the supporting structures of Kennedy Class I telescopic partial dentures using the digital parallel radiographic technique ( Digora software system).
Materials and Methods: Fourteen patients with mandibular Kennedy class I and opposing short maxillary Kennedy class I were selected. The last standing abutments for all patients were the premolars. After receiving zirconia primary crowns, patients were divided into two groups, group I received milled BioHpp telescopic RPDs, and group II received pressed BioHpp telescopic RPDs. Patients of both groups were evaluated at the time of denture insertion, at six months, and at 12 months. The evaluation included measurements of bone height changes mesial of the first abutment and distal of the second abutment and at the crest of the residual ridge.
Results: There was a statistically significant difference in the marginal bone height changes between the two groups. Group I (milled BioHpp) showed more bone resorption around the abutments than group II, while group II (pressed BioHpp) showed more resorption at the residual ridge crest than group I.
Conclusion: Milled and pressed BioHpp telescopic partial denture produced acceptable treatment options regarding bone loss. Milled BioHpp frameworks (group I) had a greater effect on bone resorption around the abutments than pressed BioHpp (group II). Pressed BioHpp showed more bone height changes at the residual ridge area than the residual ridge milled one.
