Sažetak
Purpose: In a conus crown supported denture, the longevity of the abutment teeth depend on their localization and number ; the incidence of further abutment teeth loss is greater in a small number of abutments and linear support. Additional implants in strategic positions can provide better support, better force distribution and can change linear support into a triangular or a rectangular support In narrow alveolar ridges standard diameter implants can not be inserted without augmentation. We tested if mini dental implants (MDIs) with Oball retention can be used as strategic implants for additional support and retention of removable prosthesis in patients having narrow ridges. Material and Methods: Ten patients with removable dentures retained with 1 to 2 conus crowns received 1 to 2 MDIs in order to change the linear support into triangular or rectangular. The insertion torque was > 35 N/cm2 for all MDIs and they were immediately loaded. Patients completed the OHIP-EDENT and the Chewing Function Questionnaire (CFQ) prior to MDI insertion, after MDI loading and up to 4 years. Ten patients with only 1 or 2 conus crown retained dentures were controls. Results: Ten patients have been successfully wearing the prostheses supported with one or two conus crowns and one to two MDI over 4 years ; no MDI or tooth was lost, no tooth showed mobility. The OHIP-EDENT and the CFQ questionnaire's scores were significantly reduced after MDI loading and remained low throughout the 1 to the 4 year observation stages. Control subjects showed increased abutment teeth mobility. Conclusion: Although further research for clinical validation of the described treatment is needed, preliminary clinical results indicate the effectiveness of MDI insertion as additional retention, stabilization and support of partial removable prosthesis otherwise supported by only 1 or 2 conus crowns, thus protecting abutments from overloading.
